Whatever one may say, the motherboard is the "fundamental foundation" of any system. In many ways, the possible scalability and reliability of the entire configuration depends on it. Today, we got a motherboard for testing, which, no matter how strange it sounds, is the most affordable variation from the Republic of Gamers division on the LGA1151.
I won't be mistaken if I say that components with the ROG logo are easily recognizable by enthusiasts. This series has long established itself among overclocking professionals, modding and simply lovers of good systems. Personally, my acquaintance with the boards of this series began with ASUS Rampage Extreme, and exactly with that “rampage” for LGA775. To be honest, it still works successfully in one of the systems, and after all, more than a dozen Bench sessions were held on it. At that moment, the ROG line was represented by only a few board options. But now the situation is completely different, there is IMPACT, GENE, RANGER, HERO, FORMULA and EXTREME.
So, I propose to take a look at the ASUS Maximus VIII Ranger, find out distinctive features, try to find cons and see how the system behaves during overclocking.
Contents of delivery
Packing, how could it be without it! The Ranger comes in a vertically positioned box with a detailed description on the sides, so detailed that the manufacturer used a hinged lid - everything needs to be mentioned. The design, like other ROGs, uses the familiar range of red.

The delivery set is extended, of course, it cannot be compared with the maximum variations, but you cannot call it empty either. Among the paper part, there was a place for a user manual, a cable marking kit, as well as the famous sign on the door and several ROG stickers. From the functional part, there is a blank for the case panel, a set of SATA cables, an SLI bridge and a Q-Connector adapter, and we didn’t forget about a lotion for easy installation of the processor. I listed everything, but I almost forgot to mention about the bolt for installing "bars" in the M.2 slot :).

Visual inspection
Maximus VIII Ranger is made in the reference ATX form factor, from here and the familiar dimensions of 305 x 244 millimeters. If we talk about the visual component, then black textolite is used, the element base is also in black and gray. I use cooling radiators gray shades with small inserts saturated red. As a digression, since we have already remembered the past boards of the ROG line, here is a link to a couple of photos of Rampage Extreme.

The general arrangement of the ASUS Maximus VIII Ranger elements, then in more detail.
.png)
In general, the arrangement of elements on the printed circuit board is standard, there are no obvious voids or overloaded areas. The reverse side of the board has only minor strapping elements, there are no fundamental microcircuits, let alone connectors.
Note that the Ranger has a connector for connecting an additional fan panel, the EXT_FAN port. This socket is not included in the kit, and the situation when seven standard 4pin connectors are not enough seems difficult. There is no overclocking module in the kit, with the name OC Panel, however, the ROG_EXT port for its connection is available;).
.jpg)
The list of slots of the I/O panel is extensive and quite balanced, I will list it here. Separately, we note the presence of two USB 3.1 various types and a BIOS recovery key that uses USB BIOS Flashback technology.
- One PS/2 for mouse or keyboard;
- One RJ-45 LAN connector;
- Two USB 2.0 and four USB 3.0;
- One USB 3.1 each (Type-C and Type-A);
- One HDMI and DisplayPort each;
- One optical S/PDIF;
- Five miniJack audio connectors;
- USB BIOS Flashback key;

The LGA1151 socket is ready to accept, probably, everything available processors of this performance, a complete list can be seen on the manufacturer's website. The socket itself is solidly executed, the clamping frame is painted black and tactilely a little more massive than that of the same one.
.jpg)
The processor part is powered by a ten-phase system controlled by a PWM controller labeled DIGI + EPU ASP1400B. Two phases are used to power the integrated graphics core, while the other eight supply power to the CPU itself. The element base uses assemblies marked TI CSD87350, MicroFine chokes and Black Metallic capacitors. To supply power from the PSU, one standard 8-pin connector is provided.
.jpg)
The cooling system is based on three separate aluminum alloy radiators. Two cool power system assemblies, the third is used for the Intel Z170 chipset. All radiators are fastened with bolts, two radiators are provided with backplates, which, due to the presence of thermal pads, also participate in heat removal from the back side of the board. Here I would like to praise ASUS, I remember in the old days "collective farms" small radiators from ZALMAN for "water" races.
.jpg)
In terms of RAM, everything here is quite standard for the Intel Z170: four DIMM-slots of the DDR4 standard with the ability to set the volume to 64GB. The maximum declared frequency in overclocking mode is 3400 MHz, XMP profile supported. The system with one phase is responsible for the power supply of the memory strips. It is worth noting that for older ROG models, “overclocking frequencies” make up a slightly higher bar.
.jpg)
The expansion slot configuration is as follows:
- PCI Express 3.0x1;
- PCI Express 3.0 x16 (maximum x16 lanes);
- PCI Express 3.0x1;
- PCI Express 3.0 x16 (maximum x8 lanes);
- PCI Express 3.0x1;
- PCI Express 3.0 x16 (maximum x4 lanes).
I am glad that the manufacturer has wisely approached the location of the slots, so if you want to assemble a tandem of two video cards, there will be additional space between them, which in theory will improve their temperature regime. Of course, two cards can only work in x8 + x8 mode.
.jpg)
What is the sound system based on? Correct on 7.1 channel HDA codec Realtek ALC1150. ASUS named the entire sound path SupremeFX 2015, it probably includes all the developments of the manufacturer in this direction. The component audio base is expanded to the maximum, there is an ESS ES9023P DAC and a TI RC4580 operational amplifier.
In the previous generation of motherboards, ASUS conducted an experiment with the release of an entry-level board - Maximus VI Hero, where they abandoned many controllers that expand functionality, but retained all the overclocking capabilities of the older representatives of the line, high-quality element base and an efficient cooling system.
Such a solution gained popularity, and when updating the lines, the manufacturer decided to make the board even more affordable than the Hero. The hero of the review, ASUS Maximus VII Ranger, became such a model.
Packaging and equipment
The motherboard comes in a medium-sized cardboard box, about the same size as the recently tested ASUS Z97-A. For the Republic of Gamers line, this is a bit unusual.
If we talk about the design, then continuity has been preserved here - dark red tones are used.
The front side of the package has a hinged "door":
The spread on the left lists some of the features and proprietary technologies implemented on the motherboard. On the right is a photo of the model, the manufacturer did not place a transparent window (as in the products of the upper price range).
On the back of the box are the main technical characteristics of the board, as well as an image of its interface panel.
The interior of the package is closer to regular ASUS motherboards than to ROG models. Inside, there are not the usual two boxes, one of which contains the board, and the second contains the delivery kit. No, this time the motherboard is simply placed on a cardboard pallet and additionally packed in an antistatic bag:
Under the cardboard pallet at the bottom of the box is the delivery set:
It includes:
- Q-Connector blocks for more convenient connection of the front panel of the case and two USB 2.0 ports;
- Plug for back panel corps;
- Four SATA cables;
- Set of stickers for marking cables;
- Cardboard plate for the door handle with the inscription "DO NOT DISTURB";
- Detailed user manual in English;
- Flexible SLI Bridge;
- Driver disk and software.
The delivery set cannot be called rich, but everything you need is present here. Despite the fact that the Maximus VII Ranger is the youngest member of the ROG line, the I/O panel plug is made with a soft gasket, as in the solutions of the upper price range.
Design and features of the board
ASUS Maximus VII Ranger is made in the dimensions of the ATX form factor - 305 x 244 mm.
To be honest, the motherboard looks a little “empty”, large pieces of bare textolite are striking, without an abundance of soldered controllers and strapping. There are only six SATA connectors and the lack of an interface SATA Express.
The only thing you can't complain about is the overall layout of the board: all the elements are located in their places, and the radiators of the cooling system inspire confidence. As a result, despite the rather poor equipment in general, one gets the impression of a quality product.
Confirms the general mood and look at the reverse side of the board: as soon as the question concerns reliability or overclocking orientation, there are no complaints about the motherboard. The power converter heatsinks are secured through pressure plates, and the chipset heatsink is secured with four spring-loaded screws.
There is relatively enough space around the processor socket:
Yes, power converter heatsinks can complicate the installation of some cooling systems, but there should not be a fundamental incompatibility. As for the top graphics port, it is at the height of the second expansion slot for PCI-E X1, and far enough away from the processor socket. "Fitting" Silver Arrow SB-E Extreme showed that the installed cooler does not interfere with the video card.
Four slots are soldered for DDR3 memory, which are equipped with latches only from above:
Since the graphics port is at a sufficient distance from the RAM slots, the use of latches on only one side looks like an unjustified solution that worsens the fixation of modules.
The manufacturer declared the following DDR3 operating modes: 1333, 1600, 1800 (overclocking), 1866 (overclocking), 2000 (overclocking), 2133 (overclocking), 2200 (overclocking), 2400 (overclocking), 2600 (overclocking), 2666 (overclocking) , 2800 (overclocking), 2933 (overclocking), 3000 (overclocking), 3100 (overclocking), 3200 (overclocking) MHz. List of frequencies available in motherboard BIOS boards: 800, 1066, 1333, 1400, 1600, 1800, 1866, 2000, 2133, 2200, 2400, 2600, 2666, 2800, 2933, 3000, 3200 MHz.
The maximum memory size of 32 GB indicates that the board supports 8 GB memory modules.
To activate the Dual Channel mode, you need to install memory strips in slots of the same color, that is, either 1/3 or 2/4. To provide the greatest compatibility modules and stability during overclocking, the manufacturer recommends using red connectors first, that is, a 2/4 pair. When using only one bracket, it is recommended to install it in the second slot.
Continuing the review of ASUS Maximus VII Ranger, I will say that in the upper right corner of the board, not far from the RAM slots, there are several goodies at once:
There's room for a POST code indicator, system power/reset buttons, and a MemOK! button that you can use to troubleshoot memory compatibility issues.
Expansion slot configuration:
- PCI-E 2.0 X1;
- PCI-E 3.0 X16/8;
- === empty space ===
- PCI-E 2.0 X1;
- PCI-E 3.0 X8/0;
- PCI-E 2.0 X1;
- PCI-E 2.0 X4/X2.
There are no complaints about the configuration, the graphic ports are separated by a sufficient distance, which is enough to cool multi-graphic configurations, the top graphic port is at a sufficient distance from the processor socket, since it is located at the height of the second expansion slot. Yes, only six expansion slots are used here, with the maximum seven for the ATX form factor, but the empty space is located under the graphics port, and in most cases it would still not be used, so this cannot be attributed to minuses.
ASUS motherboards are well-deservedly popular all over the world, and for good reason. This company has an impressive range of a wide variety of models, ranging from budget to the most advanced. Thanks to this, the manufacturer successfully competes in the market in various price segments. Also, a lot of attention is paid to gaming topics, whether it's extended functionality or some kind of gaming paraphernalia. With the advent of Intel Skylake processors, ASUS has replenished the specialized ROG series with several models, one of which we will consider today.

Packaging and equipment
All motherboards belonging to the premium ROG series have a similar packaging design. The model name flaunts on a dark red background, and a number of key features are indicated on the back: ROG SupremeFX 2015 sound subsystem, USB 3.1 ports (Type-A / Type-C) and support for the Keybot II function. Here you will also find detailed description functionality of the board and all ports on the back panel, and for a more complete summary, you can use the QR code.
But that's all, because the front of the box opens and allows you to get even more information on our board. The main emphasis is on indicating the components of the audio subsystem, support for proprietary technologies based on the Intel network adapter and describing the capabilities of Keybot II. A lot of attention is paid to describing the reliability of the device, which is achieved through the use of high quality components. If this is not enough for you, then on the image of the motherboard you can see the location of connectors, ports and various buttons.
Here is a typical set of ASUS MAXIMUS VIII RANGER:
- Detailed user manual and other documentation;
- Set of stickers for SATA cables and keyboards;
- Sign on the door “Game ON! You shall not pass";
- Bridge SLI;
- Plug on the rear panel of the case;
- Corporate emblem and three ROG-themed stickers;
- Four SATA 6Gb/s cables;
- CD with drivers and utilities;
- Auxiliary frame for safe installation processor;
- Q-connector for connecting cables from the front panel;
- Bolt for fixing the board in the M.2 slot.
Appearance and features of the board
What do we see on the example of ASUS MAXIMUS VIII RANGER? Great design, which is based on a combination of black textolite with stylish radiators. Despite belonging to such an outstanding series, the board's form factor obeys the classic ATX canons (305 x 244 mm). All this contributes to the compatibility of the motherboard with any productive configuration.
The manufacturer is trying to adhere to the concept of DIY (Do It Yourself). Therefore, the entire set of connectors, all kinds of ports and buttons is located in such a way as to make it as easy as possible to assemble a PC and make convenient process further operation of the device.
Let's move on to the interface panel, which includes:
- 1 x PS/2 for mouse/keyboard connection;
- 2 x USB 2.0;
- BIOS Flashback button (update BIOS from a USB-drive through a special port);
- 2 x USB 2.0;
- 1 x DisplayPort;
- 1 x HDMI;
- 1 x USB 3.1 (Type-A);
- 1 x USB 3.1 (Type-C);
- 1 x LAN (RJ45);
- 2 x USB 3.0;
- 1 x optical output;
- 5 x audio jacks.
An 8-pin connector is provided for additional power.
Next, we see 4-pin connectors CPU_OPT, CPU_FAN for connecting a processor cooler and W_Pump for powering the CBO pump. Slightly to the left are elements with the designation PA102FDG - these are P-channel field-effect transistors with logic level control, which allows you to directly control the transistor without additional drivers. Thanks to their presence, auto-tuning of fans is performed through ASUS Fan Xpert 3.
For RAM, 4 slots are available with the ability to install up to 64 GB. Declared support for a wide range of frequencies from 2133 MHz to "sky-high" 3400 MHz in overclocking mode. There is only one latch on each slot, on the other side there is a latch. This approach greatly facilitates the installation of RAM, just remember the situation when the installed video card blocked the bottom latches.
Next to the MemOK! there is a digital display of POST codes. Elements marked NTMFS4C09N are power transistors from On Semiconductor, and AS358M are two low-power operational amplifiers. In addition, there is a 4-pin CHA_FAN4 connector for connecting a case fan nearby.
Near the 24-pin connector there is a connector for outputting two USB 3.0 ports to the front panel and a 4-pin CHA_FAN2 connector for connecting a case fan. Also, I note the presence of CPU / DRAM / VGA / BOOT_DEVICE indicators, which are useful for identifying a malfunction during the initial system initialization.
All six SATA 6 Gb / s ports are based on the controller integrated into the native chipset. At the same time, two of them are separate, and the remaining four are part of two SATA Express. Declared support for Raid 0, 1, 5, 10.
Just below the heatsink is an M.2 connector that allows you to connect compatible devices of various sizes (2242/2260/2280/22110).
On the lower edge on the right is:
- Panel - connection of body panel connectors;
- EXT_FAN - connector for Fan Extension Card (card with additional ports for fans);
- CHA_FAN3 - fan connector;
- USB3_34 - USB 3.0 connector;
- USB1314/USB1112 - USB 2.0 connectors;
- ROG_EXT - port for connecting ASUS ROG panels.
VBOOT_TEST and LN2_Mode are also located here, which serves to eliminate the Cold Bug.
On the lower edge on the left you can find:
- TPM - connector for TPM module (improving system security);
- CLR_CMOS - complete reset of all BIOS settings;
- RESET - system reset button;
- START - button to turn on the system;
- TB_Header - required to connect a proprietary ThunderboltEX expansion board;
- AAFP - audio output not front panel.
Hidden under the cover labeled SupremeFX is the eight-channel Realtek ALC1150 audio codec. A little lower is the TI R4580I element, which is a dual operational amplifier specifically designed to work with the audio range. The final picture is complemented by Nichicon audio capacitors and an ESS ES9023P DAC.
The controller with ROG 035-A2 is required to use dedicated function panels.
Chip TPU (TurboV Processing Unit) - is responsible for the automatic overclocking of the processor. To the left is the BIOS chip and flash memory with the designation Winbound W25Q128FV. A little higher is an element marked IDT 6V41538NLG - it is a clock frequency generator, on the basis of which ASUS PRO Clock technology is implemented. This makes it possible to overclock the processor by increasing the value of the BLCK bus.
For expansion cards, 2 x PCIe 3.0/2.0 x16 (x8+x8), 1 x PCIe 3.0/2.0 x16 (x4), 3 x PCIe 3.0/2.0 x1 are provided. NVIDIA Support SLI and AMD CrossFireX will allow you to create configurations with multiple graphics accelerators. The nice thing here is that you can use two three-slot video cards and still have one more slot for installing a sound card or another expansion card.
For bandwidth sharing PCI-e bus specialized multiplexers ASM1480 manufactured by ASMedia are responsible.
Not far from the integrated audio codec, the Nuvoton NCT6793D controller is soldered, which is responsible for the operation of I / O devices and system monitoring.
As network controller Intel I219V is used.
Near the PCIe x1 slot there is a 4-pin connector for the CHA_FAN1 fan and a 2-pin T_Sensor connector for connecting a cable with a thermistor.
The corresponding radiators are responsible for cooling the chipset and power transistors. Two heatsinks located in the near-socket space and a heatsink for the Z170 system logic are mounted on screws. For more efficient heat transfer, special thermal pads are used.
The latest chipset Intel Z170 visually differs little from the same Intel Z97. An important feature in this case, the voltage controller for the processors has been transferred to the motherboard, which will certainly be appreciated by overclockers.
USB 3.1 ports are provided by a third-party ASMedia controller labeled ASM1142. Very close you can find the Etron EJ179V chip, which is responsible for the implementation of the USB 3.1 (Type-C) connector. To the right, the ASM1442K chip is soldered, which acts as a signal converter and is responsible for switching between HDMI and DisplayPort video outputs.
The power subsystem under the control of the DIGI + ASP1400B controller is made according to a 10-phase scheme. Texas Instruments 87350D transistor assemblies are used as power switches.
The sound path is equipped with a red backlight, support for a variety of effects is included. The implementation of the backlight is a significant plus in the direction of the gaming direction, since some of the cases are equipped with a transparent window, through which you can admire your computer assembly.
SettingsUEFIBIOS
The simplified BIOS mode is titled EZ-Mode. Basic information about the state of the system is available here, it is possible to automatically overclock using the EZ Tuning Wizard or configure the operation of connected fans through Q-Fan Control. You can also choose a boot device here, you can change the language or set the date. Speaking of the Russification of the menu, it is still far from perfect, so I recommend using the English version.
The most interesting is revealed when moving to advanced mode mode. The first tab "My Favorites" is empty by default, you can use it to create a custom window with the right set parameters. If earlier the window was empty, now the manufacturer has created his own blank and provided this page with standard set options that may come in handy when overclocking. The "Main" tab is informative and here you can only set the date / time or select the language.
"Extreme Tweaker" tab - includes all the settings necessary for overclocking (changing the processor and memory voltage, setting the processor multiplier, timings and memory frequency, etc.). In addition, there is monitoring of all possible values of the supply voltage.
The “Advanced” tab contains the rest of the list of options that do not affect overclocking. Here you can change the processor power saving settings, disable turbo mode or Hyper-threading, configure SATA ports, configure the settings of the integrated graphics controller, turn off the backlight and much more.
"Monitor" tab - monitoring of temperature and voltage indicators, as well as control of fan speed.
The Boot tab provides a number of boot optimization options and allows you to set the priority between drives.
“Tool” tab - in this tab you can update the BIOS, load a previously saved profile with system settings, or perform a full cleaning from the solid state drive (Secure Erase).

An Intel Core i7-6700K was used as the central processor. The role of the thermal interface was assigned to Arctic Cooling MX-2.
Overclocking and testing
It was decided to compare the performance of the processor in two cases, when operating at a frequency of 4000 MHz and in overclocking mode. Using the ASUS MAXIMUS VIII RANGER motherboard, we managed to increase the processor frequency by 17%, it was 4700 MHz. This result was achieved by manually setting the processor supply voltage to 1.45V. Another overclocking method is available by raising the frequency of the BCLK bus, but this should be done carefully, as it is connected to other buses. You will not be able to overclock processors without the letter K in the name using BCLK, since this opportunity essentially blocked.
I propose to get acquainted with the results of various test applications.
Thanks to the overclocking capability, we get a noticeable increase in performance in all test applications. But we should not forget about the safety of overclocking, so try not to exceed the allowable values for one or another parameter. In addition, there will be no significant spread in the obtained values between different motherboards, since the speed in this case depends only on the processor. On the other hand, the motherboard directly affects overclocking, and therefore, to some extent, performance.
Conclusion
By adding the MAXIMUS VIII RANGER to the range, ASUS has gone to meet advanced gamers and enthusiasts. The fact is that the price for this model is quite affordable, given that the motherboard in question belongs to the Republic of Gamers premium series. At the same time, the functionality of the board is so extensive that it can be safely recommended for purchase. Also, it is worth noting the successful design of the device, thanks to which it will become a worthy decoration for any gaming assembly or modding project.

According to the editors, taking into account all the pros and cons, the ASUS MAXIMUS VIII RANGER motherboard receives the Gold award.
ASUS motherboards from the Republic of Gamers product line are well-deservedly popular among overclockers and gamers. In addition, ROG family models are often chosen by advanced users who value high quality and rich expandability, as well as a number of proprietary technologies that significantly increase the functionality of devices. It is not surprising that with the release latest processors The Intel Skylake vendor has expanded the Republic of Gamers product line with LGA1151 motherboards, and today we had the honor to meet one of the representatives of the ROG series - a system ASUS board Maximus VIII Ranger.
The new product is the youngest model of the Republic of Gamers family, however, it has most of the features that are typical for ASUS gaming motherboards. A little later, we will get acquainted with the hardware and software of the Maximus VIII Ranger, as well as the results of a study of its overclocking potential and performance level, but for now I suggest that you familiarize yourself with technical specifications devices:

Contents of delivery
Thanks to the recognizable packaging design, the products ASUS gaming series on store shelves cannot be confused with competitors' products. On the front surface, decorated in dark red tones, only the name of the model is applied, and most useful information located on the back of the box.
On the back of the package there was a place for short specification motherboard and a schematic representation of the rear panel connectors, as well as information about key features Maximus VIII Ranger, such as the presence of an advanced SupremeFX 2015 sound subsystem, support for a high-speed USB 3.1 interface and proprietary Keybot II technology designed to expand the functionality of the keyboard.
The delivery set of the novelty is quite diverse, it consists of:
- detailed user manual;
- a set of mounts for SSD format NGFF;
- DVD-ROM with drivers and software;
- plugs for the back panel of the I/O Shield;
- adapter for safe installation of the processor in the socket;
- NVIDIA SLI bridge;
- four SATA 6 Gb/s cables;
- a set of stickers for the keyboard and interface cables;
- adapter Q-Connector;
- a sign on the door that reads "Game ON! You shall not pass";
- three stickers with the ROG logo on the case of the system unit.
Design
The motherboard is exactly the same size as the ATX standard, and all its main components are in their usual places. In the ASUS Maximus VIII Ranger palette, the bright red connectors that were a trademark of previous generations of ROG motherboards have been replaced by dark gray and black slots. The novelty is based on the Intel Z170 chipset and is designed to operate Skylake processors in LGA1151 design. Four DIMM slots are used to install DDR4 RAM modules. The maximum amount of RAM can reach 64 GB, and frequencies up to 3400 MHz are supported in overclocking mode.
Components on the back side of the PCB are almost non-existent except for the area behind the CPU socket where there is a pair of metal plates that are part of the power node's cooling system. However, they should not interfere with the installation of coolers with large reinforcement plates.
Excess heat from power elements The processor VRM is allotted by a pair of large heatsinks, and the design does without the use of thermosyphon tubes.
On the soles of the coolers there are gaskets made of elastic thermal interface, screw fastening ensures reliable fixation of radiators, and metal plates on the reverse side of the PCB, they not so much participate in the cooling of the voltage converter, but help prevent deformation of the textolite.
The heat from the system logic chip is removed by a medium-sized flat heatsink, however, due to the minimum heat dissipation of the PCH chip, the efficiency of such a cooling system is sufficient regardless of the operating mode.
The ASUS Maximus VIII Ranger power subsystem is powered by an eight-pin connector. The processor VRM has ten phases, of which eight channels form the voltage for the computing cores and the L3 cache, and the remaining two are responsible for powering the north bridge built into the processor. Ten integrated assemblies TI CSD87350 are used as power elements, the digital PWM controller DIGI + EPU ASP1400B is responsible for VRM control.
All components of the power supply unit fit on the front side of the PCB, and on the reverse side of the printed circuit board there are several ceramic capacitances and resistances in the SMD version.
The motherboard is equipped with seven connectors for connecting fans with support for PWM speed control, as well as a pair of pins to which an external temperature sensor is connected. Three more Carlsons and the same number of thermal sensors can be connected to an additional Fan Extension Card, for which the Maximus VIII Ranger has a special EXT_FAN port, although the card itself will have to be purchased separately. Fans of overclocking in an open testbed will appreciate the fact that the new product has power, reset and reset UEFI buttons, next to which there is a ROG_EXT connector designed to connect external module control and monitoring of the OC Panel, familiar from the reviews of the older ASUS motherboards of the Republic of Gamers family.
In the lower right corner there is an indicator of POST codes and a Mem_OK!
To install graphics accelerators, the motherboard offers a pair of PCI Express 3.0 x16 slots that can operate in x16 + x0 or x8 + x8 modes, allowing you to build AMD CrossFireX and NVIDIA SLI systems based on Maximus VIII Ranger. The third PCI Express 3.0 x16 slot is connected to the chipset and is always in [email protected], which, however, does not prevent using it to install a third AMD video card in a CrossFireX bundle. Three PCI-E 3.0 x1 ports are used to install expansion cards, and two of them are guaranteed to be available even when using graphics accelerators with massive cooling systems.
The disk subsystem of the novelty, based on the capabilities of the Intel Z170 system logic, consists of two SATA 6 Gb / s ports and two SATA Express 10 Gb / s connectors, each of which is combined with a pair of SATA 6 Gb / s interfaces. Storage devices can be combined into RAID arrays 0, 1, 5, and 10, and enable Intel Smart Response Caching Technology.
To install NGFF solid-state drives, an M.2 “Type M” port is provided, to which four PCI-E 3.0 lanes are connected. Devices with both PCI Express and SATA interfaces are supported.
The SupremeFX 2015 audio subsystem is based on the modern 7.1-channel HDA codec Realtek ALC1150. To protect against electromagnetic interference, the sound chip is covered with a metal shield, an insulating gap is made in the metal conductors of the printed circuit board, separating the audio subsystem from the rest of the motherboard. The headphone output uses digital-to-analogue converter ESS ES9023P. The output stages are equipped with Japanese electrolytic capacitors NICHICON, to work with stereo headsets with high internal resistance used operational amplifier RC4580. In addition, a miniature electromagnetic relay is used to prevent clicking when power is applied to the motherboard.
For work Gigabit networks Ethernet is responsible for the Intel I219V controller, and for connecting various peripherals, ASUS Maximus VIII Ranger has eight chipset USB ports 2.0 and six USB 3.0 channels. The optional ASMedia ASM1142 controller provides two USB 3.1 interfaces with throughput 10 Gbit / s, moreover, one of them has a "Type C" version. As a result, on the rear panel of the Maximus VIII Ranger there was a place for:
- PS/2 combo port;
- four USB 2.0 interfaces and USB pairs 3.0;
- USB BIOS Flashback buttons;
- HDMI and DisplayPort digital video outputs;
- network socket RJ-45;
- one USB 3.1 Type A (red) and one USB 3.1 Type C;
- digital optical audio output S/PDIF;
- five analog audio connectors with gold-plated inserts.
The motherboard supports the USB BIOS Flashback function, designed to update the control microcode without the need to install a central processor and RAM modules, which is enabled by the button of the same name. In addition, it should be noted that digital video outputs support image output in 4K resolution. UEFI Setup
The Maximus VIII Ranger motherboard is equipped with UEFI-based firmware, the setup menu interface is reminiscent of ASUS Republic of Gamers motherboards based on Intel 9-series chipsets. UEFI Setup offers two modes: a simplified EZ Mode, which is used for the basic configuration of the motherboard, and an advanced Advanced Mode, designed to fine-tune all possible firmware parameters. EZ Mode provides users with basic information about the operating modes of the main components and displays hardware monitoring readings. In addition, in Easy Mode, you can enable X.M.P. profiles, set the date and time, and set the fan mode.
To improve performance, you can use the EZ Tuning wizard, which allows you to optimize performance personal computer depending on the type of cooling system used and the nature of the tasks performed.
Unlike EZ Mode, where only basic settings are available, in advanced mode, users have full control on UEFI. So, in the Main section, information about the version of the control microcode is displayed and the menu display language is selected. At the same time, an information panel is located on the right side of the interface, which displays the current parameters of the CPU and RAM, as well as the voltage on the main power buses.
The Extreme Tweaker tab is responsible for numerous overclocking and performance enhancement options. It is here that the base frequency and multipliers of processor cores are set, the MultiCore Enhancement option is turned on, which increases performance in single-threaded applications, the RAM mode is configured, and the EPU Power Saving Mode is activated.
Maximus VIII Ranger firmware offers several sets of settings increased performance, which are located in the Overclocking Presets subsection. In addition, UEFI Setup allows you to choose one of two automatic overclocking profiles TPU I and TPU II, the effectiveness of which will be evaluated in the practical part of today's review.
For the RAM subsystem, you can select a clock frequency up to 4266 MHz inclusive, and in the DRAM Timing Control submenu you can adjust the main and many additional timings that will help you set any RAM for maximum performance.
The DIGI+ VRM tab is responsible for managing the digital power subsystem, including the Load-line Calibration option, switching frequency of power elements, and shutting down unused VRM phases at moments of minimum load.
A number of secondary voltages are also set here, fine tuning of which can improve overclocking results.
| Parameter | Voltage range, V | Step, B |
| CPU Core/Cache Boot Voltage | 0,6-1,7 | 0,005 |
| DMI Boot Voltage | 0,3-1,9 | 0,01 |
| Core PLL Boot Voltage | 0,7-1,6 | 0,00625 |
| CPU System Agent Boot Voltage | 0,7-1,8 | 0,0125 |
| CPU VCCIO Boot Voltage | 0,7-1,8 | 0,0125 |
In the Internal CPU submenu power management controls for Intel SpeedStep functions and turbo boost, as well as limits on the power consumed by the processor.
In the Tweakers Paradise subsection, experienced overclockers will find many interesting options that will help them achieve high clock frequencies, including adjusting some specific voltages.
| Parameter | Voltage range, V | Step, B |
| DRAM VTT Voltage | 0,5-1,3 | 0,00625 |
| VPPDDR Voltage | 1,865-3,135 | 0,005 |
| DMI Voltage | 0,3-1,9 | 0,01 |
| Core PLL Voltage | 0,7-1,6 | 0,00625 |
| Eventual DRAM Voltage | 1,0032-2,0064 | 0,0066 |
| Eventual CPU Stanby Voltage | 0,8-1,8 | 0,00625 |
Among other things, the Extreme Tweaker tab allows you to set the multiplier for the L3 cache memory, as well as manage the power supply on the processor, RAM modules, and all major motherboard components.
Several control modes are available for the voltage on the computing cores and the L3 cache, including Manual, in which the required value is specified explicitly, as well as Offset, where users can set an increase to the nominal value, and Adaptive, which combines the capabilities of the two previous ones. A complete list of parameters, their ranges and change steps are given in the following table:
| Parameter | Voltage range, V | Step, B |
| CPU Core/Cache Voltage Override | 0,6-1,7 | 0,005 |
| CPU Core/Cache Voltage Offset | -0,635…+0,635 | 0,005 |
| DRAM Voltage | 1,0032-2,0064 | 0,0066 |
| CPU VCCIO Voltage | 0,7-1,8 | 0,0125 |
| CPU System Agent Voltage Offset | 0,7-1,8 | 0,0125 |
| PCH Core Voltage | 0,7-1,8 | 0,0125 |
| CPU Stanby Voltage | 0,8-1,8 | 0,00625 |
The Advanced section is responsible for setting up extension functions and implementing additional features motherboard.
The CPU Configuration tab is used to display detailed information about the CPU, configuring its specific features such as Hyper-Threading and hardware virtualization, and configuring CPU power saving features.
The System Agent (SA) Configuration submenu is intended for managing the integrated graphics adapter and built-in north bridge, and ROG Effects allows you to turn off the LED backlight.
Settings additional controllers are located in the Onboard Device Configuration subsection, and the SSD SMART Information tab displays the status disk drives, moreover, not only solid-state, but also NMWR.
The functions of hardware monitoring and setting the fan operation mode can be found in the Monitor section, which displays temperatures from three built-in and four external thermocouples, displays the rotation speeds of the impellers of ten coolers, and voltage readings on the processor and main power buses.
Carlson speed control is located in the Q-Fan Configuration submenu. For each of the ten fans, you can choose one of the three built-in profiles, or set the operation mode manually by linking the speed with the readings of one of the temperature sensors.
Among the additional features of the Maximus VIII Ranger setup menu, one cannot fail to note the EZ Flash 3 utility, which allows you to update the control microcode, including via the Internet, and the SSD Secure Erase function, designed for low-level cleaning of solid state drives.
In addition, new items in UEFI Setup allow you to save up to eight profiles with settings and view the SPD parameters of RAM modules.
Complete software
ASUS pays special attention to the software component of its products, and Maximus VIII Ranger is no exception to this rule. Along with the motherboard, buyers receive a set of all the necessary drivers and a range of software, of which overclockers will surely be interested in the Ai Suite 3 application. It includes many functional modules, which are responsible for controlling the speed and mode of operation of the cooling system, fine-tuning the power subsystem and implementing additional functions. At the bottom of the window is an information panel that displays system monitoring readings. After launching the program, the Dual Intelligent Processor 5 module opens by default, which is used for overclocking, power saving management, fan settings and much more.
With the 5-Way Optimization utility, users can take advantage of the automatic performance optimization function, and experts have the opportunity to intervene in this process to achieve the best results.
The TPU module serves to manual control acceleration parameters, and Fan Xpert 3 is responsible for adjusting the speed of rotation of the cooler impellers, both in automatic and manual modes.
The DIGI+ VRM subroutine is designed to configure the digital power subsystem, it allows you to adjust the operation of the Load-line Calibration function, set the switching frequency of power elements and turn off unused phases of the voltage converter at minimum load.
The Dual Intelligent Processor 5 includes the Turbo App utility, with which you can select the performance profile, fan operation mode, network and sound subsystems for each application, as well as the EPU software module that is used to enable proprietary features reducing energy consumption.
In addition to the above, users are offered a subroutine for cleaning hard disk from temporary files, which will help improve the responsiveness and speed of the operating system.
In the event that of all the features of the Ai Suite 3 software product, only overclocking functions are needed, it makes sense to use the TurboV Core utility. This small program has a minimalistic interface, but allows you to adjust all the basic overclocking parameters.
To adjust the delays of the RAM subsystem, the manufacturer offers the Mem TweakIt application, which, unfortunately, is this moment does not allow you to adjust timings, but can be used to obtain comprehensive information about the current mode of operation of memory modules.
One way to improve system responsiveness and performance is to cache frequently accessed data from disk drives in a dedicated area of RAM. For these purposes, ASUS offers the RAMCache utility, which allows you to select a storage device, as well as specify the amount of RAM to store temporary data.
Thanks to proprietary Keybot II technology, users have the ability to record macros and assign hotkeys to any keyboard.
Fans of online battles may appreciate the function of managing network connection bandwidth using the GameFirst III application, which allows you to set network packets gaming applications highest priority, including through low-level interaction with ASUS routers that support ROG First technology.
Finally, it is impossible not to mention the convenient and functional utility Sonic Studio II, designed to implement software effects for sound processing, noise reduction for the microphone and increase voice intelligibility.
The study of the overclocking potential and the level of performance of the ASUS Maximus VIII Ranger motherboard was carried out as part of test system the following configuration:
- processor: Intel Core i7-6700K (4.0 GHz, 4 cores 8 threads, 8 MB L3 cache);

The frequency potential of the ASUS Maximus VIII Ranger was evaluated using an engineering sample of the Intel Core i7-6700K. Using the powerful Noctua NH-D15 air cooler, the motherboard overclocked the test Skylake to 4700 MHz, while the L3 cache ran at 4500 MHz. The CPU Core/Cache Voltage parameter has been increased to 1.35 V, which, together with the setting of CPU Load-line Calibration to Level 6, provided a voltage within 1.35 ± 0.02 V, judging by the data program monitoring. At the same time, the system demonstrated absolute stability during the LinX stress test, and the temperature of the hottest core did not exceed 92 ° C.
As for overclocking the RAM subsystem, the "motherboard" made it possible to raise the frequency of the Kingston HX424C15FBK4 / 32 test kit to 3066 MHz with timings of 15-16-16-36-1T. At the same time, 1.39 V was supplied to the memory modules, and the nominal voltage of the "system agent" was increased by 0.15 V.
In terms of increasing BCLK, the novelty did not disappoint, allowing you to overclock the base frequency to 350 MHz. Interestingly, the key parameter that ensured stability was the CPU Stanby Voltage, which had to be increased to 1.5 V. Otherwise, there were problems with the "cold start" of the motherboard.
Of all the automatic overclocking features, the best results were obtained using the TPU II profile, the activation of which led to an increase in the base frequency to 4600 MHz when the voltage was increased to 1.42 V. It should be noted that such a high Vcore value is clearly excessive for our Core i7-6700K , so this mode can be recommended only to owners of highly efficient cooling systems.
The result of the optimization wizard EZ Wizard was the overclocking of the processor to 4527 MHz, which was obtained by increasing the multiplier to 44 while increasing BCLK to 103 MHz. At the same time, the firmware independently increased the CPU Core / Сache Voltage to 1.34 V, which can be considered optimal value for such overclocking.
As for measuring fps in modern video games, in three out of four cases, the productivity of ASUS Maximus VIII Ranger turned out to be at the level of rivals, while in the real-time strategy Star Craft II, the novelty significantly took the lead.
power usage
To evaluate the energy consumption of test benches, the Basetech Cost Control 3000 instrument was used, with which the average level idle power consumption and peak power consumption during the LinX 0.6.5 stress test.
As measured by ASUS Maximus VIII Ranger proved to be the most economical both in the absence of load and intensive use of CPU computing resources.
conclusions
Undoubtedly, the junior ASUS model in the product line of Republic of Gamers motherboards deserves every attention. Thanks to a well-thought-out design and high-quality element base, the Maximus VIII Ranger showed an excellent margin of safety during overclocking, except that it was not possible to reach the maximum frequencies for the RAM subsystem. But, in normal mode, the novelty pleased with a high level of performance and moderate power consumption. At the same time, the device is endowed with the Keybot II function and support for GameFirst network traffic prioritization technology, and also has an advanced SupremeFX 2015 sound subsystem, which will be appreciated by gamers. Traditionally, the wealth of settings and stability of UEFI Setup are at the highest level for ROG series products, and the bundled software successfully complements the functionality of the firmware. As for the expansion options, their list is close to optimal, but not overloaded with redundant options, which in the end significantly increase the price of the product. The same applies to the delivery set: nothing superfluous, but at the same time, all the necessary accessories are available.
As for the retail price of ASUS Maximus VIII Ranger, at the time of writing the review, Ukrainian online stores were asking for about $250 for the novelty. Let's hope that the excitement around the components for the Intel LGA1151 platform will subside, and the youngest of the "motherboards" of the Republic of Gamers family will fall in price by at least 10%, but even now it can be recommended for purchase as the basis for a powerful gaming PC or a powerful tool for the brave overclocking experiments.
The Asus Maximus VIII Ranger motherboard, of course, is not new for a long time, but it is still relevant today and will remain so for a long time to come. This board belongs to the elite gaming (ROG) series based on Intel chipset Z170, which was called Maximus VIII. In this series, the Ranger model is the most inexpensive solution with a minimum package, but it has everything you need to assemble a productive gaming PC on its basis.
In addition to the Ranger, the Asus Maximus VIII series includes models such as Formula, Extreme, Gene, Hero, Impact, as well as several variations based on these models. All boards in this series only support 6th generation Intel Core (Skylake-S) processors.
Completion and packaging
The Asus Maximus VIII Ranger board comes in a small burgundy box, on which all the advantages of the board are eloquently painted. The delivery set is very modest. In addition to the board itself, a user manual (only in English), a DVD with software and drivers, two SATA cables (all connectors are latched), an SLI bridge for two video cards, a rear panel cover, a traditional Q-connector, and there is also a plastic mounting frame designed to facilitate the installation of the processor into the socket (many Asus motherboards are equipped with such frames).

Form Factor
The Asus Maximus VIII Ranger board is made in the ATX form factor (305×244 mm), and nine standard holes are provided for mounting it into the case.
Chipset and processor socket
The Asus Maximus VIII Ranger board is based on the Intel Z170 chipset and only supports 6th Gen Intel Core processors with an LGA1151 socket (codenamed Skylake-S)
Memory
The Asus Maximus VIII Ranger board has four DIMM slots for installing memory modules (dual-channel operation). The user manual notes that the board supports unbuffered DDR4 (non-ECC) memory. Memory with XMP profiles is supported, and the maximum memory can be 64 GB (when using 16 GB modules)
Expansion slots and M.2 connector
For installing video cards and expansion cards, the Asus Maximus VIII Ranger motherboard provides three slots with the form factor PCI Express 3.0 x16 (PCIe 3.0 x16), three PCI Express 3.0 x1 slots and an M.2 connector
Of the three slots with the PCI Express 3.0 x16 form factor, the first two (counting from the processor socket) are based on 16 PCIe 3.0 processor lines (these two slots differ in color - they are gray), and the third slot is based on 4 chipset lines PCIe 3.0, that is, it is a PCI Express 3.0 x4 slot in the PCI Express x16 form factor. The operation of the last PCI Express 3.0 x4 slot has nothing to do with the operation of the first two slots. And the first two slots with PCI Express 3.0 x16 form factor (based on processor lines) work as follows.
The first (counting from the processor socket) PCI Express 3.0 x16 form factor slot is switchable and can operate at x16 speed or at x8 speed. The second PCI Express 3.0 x16 slot always works only at x8 speed (in fact, it is a PCI Express 3.0 x8 slot). Accordingly, the following two modes of operation are implemented for these two slots: x16/- or x8/x8. That is, if only the first slot is used, then it will work in x16 mode. If the first and second slots are used, they will run at x8 speed. To switch the operating modes of PCIe 3.0 x16 slots, ASMedia ASM1480 multiplexers / demultiplexers of PCI Express 3.0 lines are used.
When installing two discrete Nvidia GPU-based graphics cards, Nvidia SLI technology is supported, and when installing AMD GPU-based graphics cards, CrossFireX technology for two (x8/x8) and three (x8/x4/x4) graphics cards is supported. In the case of three AMD graphics cards a PCI Express 3.0 x4 chipset slot is also used.
Three PCI Express 3.0 x1 slots implemented via Intel Z170 chipset
In addition, the board has an M.2 connector that allows you to install 2242/2260/2280/22110 drives. This connector supports PCIe 3.0 x4 and SATA 6Gb/s drives, and it uses four PCIe 3.0 chipset ports and one SATA 6Gb/s port.
Video connectors
Since Skylake processors have an integrated graphics core, and the Intel Z170 chipset supports the use of processor graphics, to connect a monitor on the back of the board there is a DisplayPort 1.2 video output (4096× [email protected] Hz) and HDMI 1.4b video output (4096× [email protected] Hz).
SATA ports, SATA Express connectors
To connect drives or optical drives, the board provides six SATA 6 Gb / s ports and two SATA Express connectors. All SATA 6 Gb / s ports are based on the SATA controller integrated into the chipset and support the ability to create RAID arrays of levels 0, 1, 5 and 10. Moreover, four of these six ports are part of two SATA Express connectors. Recall also that for the implementation of each SATA Express connector, in addition to two SATA 6 Gb / s chipset ports, two PCIe 3.0 chipset ports are also used.
USB connectors
The board provides six USB 3.0 ports, two USB 3.1 ports, and eight USB 2.0 ports for connecting all kinds of peripheral devices.
USB 3.0 and USB 2.0 ports are based on the Intel Z170 chipset (recall that the chipset supports up to 14 USB ports, of which up to 10 ports can be USB 3.0). Moreover, two USB 3.0 ports and four USB 2.0 ports are placed on the rear panel of the board, and to connect four more USB 3.0 ports and four USB 2.0 ports, the board provides the corresponding connectors (two connectors for USB 3.0 ports and two connectors for USB 2.0 ports) .
To implement two USB 3.1 ports on the board, the ASMedia ASM 1142 dual-port controller is used. Both USB 3.1 ports are routed to the rear panel of the board. Moreover, one port has a Type-A connector, and the other port has a symmetrical Type-C connector.
network interface
To connect to the network, the Asus Maximus VIII Ranger board has a gigabit network interface based on the PHY controller (physical layer controller) Intel i219-V (the MAC layer controller integrated into the chipset is used). This controller uses the PCIe chipset port for connection.
How it works
Traditionally, we recall that the Intel Z170 chipset has up to 20 PCI Express 3.0 ports (lines), up to 10 USB 3.0 ports and up to 6 SATA 6 Gb / s ports. In this case, there can be no more than 26 high-speed ports (PCIe, USB 3.0 and SATA 6 Gb / s).
Well, now let's see how the capabilities of the Intel Z170 chipset are implemented on the Asus Maximus VIII Ranger board. Actually, everything is quite simple here.
Indeed, let's count the number of controllers, connectors and slots that connect to the PCIe chipset ports. A PCI Express 3.0 x4 slot and three PCI Express 3.0 x1 slots require a total of seven PCIe ports. Intel controllers i219-V and ASMedia ASM 1142 are 3 more PCIe ports. In addition, we take into account the M.2 connector and two SATA Express connectors, which require 8 more PCIe ports. That is, in total, 18 PCIe chipset ports are required, that is, even less than what the chipset can provide. However, despite the fact that there are enough PCIe chipset ports for everything, the PCI Express 3.0 x4 slot shares two chipset ports with two PCI slots Express 3.0x1. By default, the PCI Express 3.0 x4 slot works in x2 mode, in which case all PCI Express 3.0 x1 slots are available, but if the PCI Express 3.0 x4 slot works in x4 mode, then two PCI Express 3.0 x1 slots will be unavailable. With this separation, a total of 16 PCIe chipset ports are required. Of course, it is not very clear why it was necessary to share a PCI Express 3.0 x4 slot with two PCI Express 3.0 x1 slots. Apparently, this is just a legacy from some other board (as we assume, the Asus Maximus VIII Hero board), which was taken as the basis for the Asus Maximus VIII Ranger board.
The only thing left to figure out is the total number of high-speed I / O ports, which should be no more than 26. In this case, you need to take into account that only two high-speed ports are required for each SATA Express connector, which can be configured as either two SATA ports or two ports PCIe 3.0. In addition, the M.2 connector shares the SATA chipset port with the first SATA connector on the board, meaning that if the M.2 connector is in SATA mode, the first SATA 6Gb/s port on the board will be unavailable. If we take into account 6 more USB 3.0 ports implemented through the chipset, then we will get a total of 24 high-speed I / O ports. The block diagram of the Asus Maximus VIII Ranger board is shown in the figure.
Additional features
As with all boards in the Maximus VIII series, the Asus Maximus VIII Ranger has quite a few extras.
Let's start with the fact that the board has power, reset, reset BIOS (Clear CMOS) buttons, as well as a POST code indicator. There is also a Mem OK button, traditional for Asus boards!
A USB BIOS Flashback button is located on the back of the board for easy updating. Board BIOS using a USB flash drive. To do this, you just need to copy the BIOS to a USB flash drive and, after inserting it into a special USB 2.0 port, press and hold the USB BIOS Flashback button for 3 seconds.
The next feature is the presence of the LN2 jumper, which is important for extreme overclocking.
Another feature of the board is the presence of the FAN Extension connector, which is designed to connect the Asus Fan Extension board (included in the package). This board allows you to connect four additional fans and three thermal sensors.
There is also a two-pin connector on the board for connecting one temperature sensor.
There is another specific ROG Extension connector on the board, which is designed to connect various accessories ROG series. But these accessories are not included in the package.
Another feature of the board is the presence of a panel of LED indicators Q LED, which allow you to perform primary diagnostics of the system during its boot. These LEDs are located in front of the 24-pin power connector.
Supply system
Like most boards, the Asus Maximus VIII Ranger model has 24-pin and 8-pin power supply connectors.
The CPU voltage regulator on the Asus Maximus VIII Ranger board is 10-channel based on a PWM controller labeled Digi+ VRM ASP1400. The power channels themselves use NexFET chips (one chip per channel).
Cooling system
To cool various heat-producing components, the Asus Maximus VIII Ranger board has a total of three heatsinks. One separate heatsink is installed on the chipset, and two more heatsinks are installed on both sides of the processor socket and remove heat from the processor voltage regulator elements.
In addition, to create an efficient heat dissipation system, the board has six four-pin fan connectors (including the CPU cooler fan). In addition, there is a separate four-pin connector for connecting a water cooling pump, as well as a two-pin connector for connecting a temperature sensor (not included in the kit)
As already noted, the board also has a special Fan Extension connector for the Asus Fan Extension board (not included), which allows you to connect four additional fans and three thermal sensors. Traditionally, the speed of any fan, including fans connected to the Asus Fan Extension board, can be configured either through the UEFI BIOS or through the Asus Fan Xpert 3 utility.
Audio subsystem
The Asus Maximus VIII board's audio subsystem is marketed as ROG SupremeFX 2015. It includes the popular Realtek ALC1150 8-channel (7.1) HDA audio codec. However, it is not so much the audio codec that is of interest, but other elements of the audio path: ESS ES9023P DAC, dedicated clock generator, specialized Texas Instruments RC4580 headphone amplifier, Nichicon capacitors, etc. All elements of the audio path are isolated at the level of PCB layers from other board components and allocated to a separate zone .
The rear panel of the board has five minijack audio connectors (3.5 mm) and one optical S/PDIF connector (output).
To test the output sound path intended for connecting headphones or external acoustics, we used the Right Mark Audio Analyzer 6.3.0 utility and an external Creative E-MU 0204 USB sound card. Testing was conducted for stereo mode, 24-bit/44.1 kHz.
According to the test results, the audio section on the Asus Maximus VIII Ranger board received a "Very good" rating.
The full report with the results of testing in the RMAA 6.3.0 program is placed on a separate page, a brief report is given below.

UEFI BIOS
If we talk about the UEFI BIOS, then it is completely standard. Exactly the same UEFI BIOS (in terms of interface and capabilities) is used on the Asus Maximus VIII Gene board or, for example, on the Asus Maximus VIII Formula board. We will not repeat ourselves and refer the reader to the relevant articles.
