In this article we will look at the Asus ROG Strix Z370-E Gaming gaming motherboard from the Asus ROG (Republic Of Gamers) series on the Intel Z370 chipset for Coffee Lake processors.
Options and packaging
The Asus ROG Strix Z370-E Gaming board comes in a small box.
The package includes a user manual, a DVD with drivers and utilities, cable stickers, four SATA cables (all connectors with latches, two cables have an angled connector on one side), a plug for the rear panel of the board, an SLI bridge for two video cards , antenna for Wi-Fi module, cable for connecting an RGB strip, cable for connecting an addressable RGB strip, one thermal sensor, a set of cable ties, a holder for installing an additional fan measuring 40x40 or 50x50 mm on the board (itself fan not included) and a plastic frame for safe installation of the processor in the socket.
Board hardware configuration
A summary table of the characteristics of the Asus ROG Strix Z370-E Gaming board is given below, and then we will look at all its features and functionality.
The Asus ROG Strix Z370-E Gaming board is made in the ATX form factor (305x244 mm). For its installation in the housing, standard nine holes are provided.
The board is based on the new Intel Z370 chipset. Accordingly, the board only supports processors Intel Core 8th generation (code name Coffee Lake) with LGA1151 connector.
Since Coffee Lake processors have an integrated graphics core, there are Display Port 1.2, DVI-D and HDMI 1.4 video outputs on the rear panel of the board to connect a monitor.
To install memory modules, the Asus ROG Strix Z370-E Gaming board has four DIMM slots. Unbuffered DDR4 (non-ECC) memory is supported, and the maximum memory capacity is 64 GB (using 16 GB modules).
To connect storage devices or optical drives, the board has six SATA 6 Gb/s ports, which are implemented on the basis of a controller integrated into the Intel Z370 chipset. These ports support the ability to create RAID arrays of levels 0, 1, 5, 10.
One of the features of the board is large number implemented USB ports. Thus, there are six USB 3.0 ports, six USB 2.0 ports and three USB 3.1 ports.
All USB 2.0 and USB 3.0 ports are implemented directly through the Intel Z370 chipset. Two USB 2.0 ports and two USB 3.0 ports are located on the rear panel of the board, and to connect four more USB 2.0 ports and four USB 3.0 ports, the board has two USB 2.0 connectors and two USB 3.0 connectors (two ports per connector).
Two USB 3.1 ports located on the rear panel of the board are based on the ASMedia ASM3142 controller, which connects to the chipset via two PCIe 3.0 lines. One of these ports has a Type-A connector, and the other has a Type-C connector.
The board also has another vertical connector (a typical connector for Asus boards) for connecting the front USB 3.1 port, which is implemented on the basis of another ASMedia ASM3142 controller.
To connect to the network, the Asus ROG Strix Z370-E Gaming board has a gigabit network interface and a Wi-Fi 802.11b/g/n/ac wireless interface. The gigabit network interface is implemented based on the Intel I219-V physical layer controller (used in combination with a chipset MAC-level controller). The Wi-Fi module is based on the Realtek RTL8822BE controller. This module is installed in a vertical M.2 connector.
For installing video cards, expansion cards and drives, the board has three slots with the PCI Express x16 form factor, four PCI Express 3.0 x1 slots and two M.2 connectors.
The first (if you count from the processor socket) slot with the PCI Express x16 form factor (PCIE_X16/X8_1) is implemented based on PCIe 3.0 processor lines and is a PCI Express 3.0 x16 slot. This is a switchable slot that can operate at x16/x8 speeds (multiplexers-demultiplexers of PCIe 3.0 ASMedia ASM1480 lines are responsible for switching lines).
The second slot with the PCI Express x16 form factor (PCIE_X8_2) is also based on PCIe 3.0 processor lines, but always operates at x8 speed. In other words, this is a PCI Express 3.0 x8 slot, but in the PCI Express x16 form factor.
The third slot with the PCI Express x16 form factor (PCIE_X4) is implemented on the basis of PCIe 3.0 chipset lines and is a PCI Express 3.0 x4 slot, but in the PCI Express x16 form factor.
The operating mode of the PCIE_X4 slot based on PCIe 3.0 chipset lines is in no way related to the operation of other slots implemented on the basis of PCIe 3.0 processor lines. The operating modes of the PCIE_X16/X8_1/PCIE_X8_2 slots, that is, slots based on 16 PCIe 3.0 processor lines, can be as follows: x16/—, x8/x8.
The board supports Nvidia SLI and AMD CrossFireX technologies and allows installation of two Nvidia video cards ( symmetrical mode x8/x8), as well as two or three (in x8/x8/x4 mode) AMD video cards.
PCI Express 3.0 x1 slots are implemented via the Intel Z370 chipset.
In addition to the PCI Express slots, the board has two M.2 connectors, which are designed for SSD drives with a standard size of 2242/2260/2280. One connector (M2_1) supports PCIe 3.0 x4 and SATA drives, while the other (M2_2) supports only PCIe 3.0 x4 drives.
Like most boards, the Asus ROG Strix Z370-E Gaming model has 24-pin and 8-pin connectors for connecting the power supply. The processor supply voltage regulator on the board is controlled by an ASP1400BT PWM controller in combination with six MOSFET drivers. The power channels themselves use SiRA12DP and SiRA14DP MOSFET transistors from Vishay Intertechnology.
The board's cooling system consists of three radiators. Two heatsinks are located on two adjacent sides of the processor socket and are designed to remove heat from the MOSFET transistors of the processor voltage regulator. Another radiator consists of two parts. One part is intended for cooling the chipset, and the second is for cooling the SSD drive installed in the M.2_1 connector.
In addition, to create an effective heat dissipation system, the board has six four-pin connectors for connecting fans. Two connectors are for the processor cooler, and two more are for additional case fans. One connector can be used to connect the CBO pump, and another one can be used for the cooling fan of the SSD drive installed in the M.2 connector. In addition, there is a connector for connecting an Asus Fan Extension card (not included in the package), as well as a connector for a temperature sensor.
The audio subsystem of the Asus ROG Strix Z370-E Gaming board is based on the Realtek ALC1220 codec and is isolated at the PCB layer level from other board components. The rear panel of the board has five mini-jack audio connectors (3.5 mm) and one S/PDIF optical connector (output).
How does this work
Now, after a brief introduction to technical characteristics Asus ROG Strix Z370-E Gaming board, let's see what is shared with what (if it is shared at all), that is, whether the capabilities of the Intel Z370 chipset are enough to implement the entire set of ports, slots and controllers that were discussed above, without separating them from each other with a friend.
Let's remember that the Intel Z370 chipset has 30 high-speed input/output ports (HSIO), which can be PCIe 3.0, USB 3.0 and SATA 6 Gb/s ports. Some ports are strictly fixed, but there are HSIO ports that can be configured as USB 3.0 or PCIe 3.0, SATA or PCIe 3.0. Moreover, in total there can be no more than 10 USB 3.0 ports, no more than 6 SATA ports and no more than 24 PCIe 3.0 ports.
The chipset on the board includes: a PCI Express 3.0 x4 slot, four PCI Express 3.0 x1 slots, two M.2 connectors, a network controller, a Wi-Fi module and two ASMedia ASM3142 controllers. All this together requires 22 PCIe 3.0 ports. In addition, six SATA ports and six USB 3.0 ports are used, which means another 12 HSIO ports. In other words, there are 34 HSIO ports in total. And we haven’t yet taken into account that one M.2 connector can operate in SATA mode. It is clear that you cannot do without separation of ports and connectors.
The M.2_1 connector is shared along the SATA line with the SATA#1 port, that is, if the M.2 connector is used in SATA mode, then the SATA#1 port will be unavailable. Conversely, if SATA#1 port is used, then the M.2 connector is only available in PCIe 3.0 x4 mode.
The M.2_2 connector is shared with the SATA#5 and SATA#6 ports as follows. The chipset's two HSIO ports can be configured as either two SATA ports (SATA#5, SATA#6) or two PCIe 3.0 ports. If these ports are configured as two PCIe 3.0 ports, then together with two more chipset PCIe 3.0 ports we get four PCIe 3.0 ports, which are used for the M.2_2 connector in PCIe mode. If ports SATA#5 and SATA#6 are used (that is, two HSIO ports of the chipset are configured as two SATA ports), then the M.2_2 connector is only available in PCIe 3.0 x2 mode. The operating mode of the M.2_2 connector is set in the BIOS settings.
In addition, one ASMedia ASM3142 controller, on the basis of which a vertical connector for connecting the front USB 3.1 port is implemented, is shared with two PCI Express 3.0 x1 slots (PCIE_x1_2 and PCIE_x1_4). The operating mode (PCIE_x1_2 and PCIE_x1_4 slots or ASMedia ASM3142 controller) is set in the BIOS settings.
Taking into account the specified divisions, all 30 high-speed chipset ports are used on the board: 18 PCIe 3.0 ports, 4 SATA ports and 6 USB 3.0 ports. Two more chipset HSIO ports can be configured as either two SATA ports or two PCIe 3.0 ports.
The block diagram of the Asus ROG Strix Z370-E Gaming board is shown in the figure.
Additional Features
The Asus ROG Strix Z370-E Gaming board does not belong to the top segment and does not have many additional features. There is no POST code indicator or any buttons. There is only a CLRTC jumper for resetting BIOS settings and a two-position CPU_OV jumper, which allows you to set higher voltage values on the processor when overclocking it.
The only thing that can be noted is the implementation of RGB lighting for the connector panel casing. The backlighting of the casing is quite bright and expressive. The backlight is configured traditionally using the Asus Aura Sync utility, which allows you to select the backlight color and various effects.
But nothing else on the board is highlighted.
In addition to illuminating the connector panel casing, the board has three connectors for connecting LED strips. Two four-pin connectors (12V/G/R/B) are designed to connect 12V LED strips of the 5050 RGB LED type, and one three-pin (5V/D/G) connector is for connecting a WS2812B digital strip with individually addressable LEDs. The LED strips are controlled through the same Asus Aura Sync utility that is used to control the board backlight.
Among the additional features, we can also note the presence of a five-pin connector for connecting a Fan Extension board, which allows you to connect additional fans and thermal sensors, as well as the presence of a connector for connecting a COM port (although this is unlikely to be needed by anyone today).
And the last thing worth mentioning is the presence of special mounting holes for attaching modding elements made on a 3D printer to the board.
UEFI BIOS
Of course, there is nothing special in the UEFI BIOS of the Asus ROG Strix Z370-E Gaming that would not be present on other Asus boards based on the Intel Z370 chipset. Actually, this is how it should be. Everything is standard, typical and functional.
Diagnosis
The Asus ROG Strix Z370-E Gaming board can be considered as classic version solutions based on the Intel Z370 chipset. On the one hand, it is quite simple (for a solution based on the Intel Z370 chipset), on the other hand, everything you need and even more is on the board.
Indeed, in addition to traditional SATA ports, there are two M.2 connectors, which will allow you to create a very high-performance data storage subsystem. For example, two M.2 drives with a PCIe 3.0 x4 interface can be combined into RAID 0 and this array can be used as a system drive, while slower but capacious HDDs can be connected to SATA ports. However, even one M.2 drive with a PCIe 3.0 x4 interface will be quite enough for a high-performance PC.
Let's add here the presence of modern USB 3.1 ports, the ability to install two video cards in Nvidia SLI or AMD CrossFireX mode, as well as the presence of a wireless Wi-Fi module.
If a K-series processor is used in combination with the board, then the UEFI BIOS of the board provides excellent opportunities for overclocking the processor. In addition, it is possible to create an efficient, customizable cooling system.
What distinguishes this board from top solutions is the lack of sophisticated backlighting, which, by the way, not everyone needs. However, the absence of sophisticated lighting in this case does not mean, of course, that it cannot be created. The board has three connectors for connecting LED strips. So lovers of transparent cases will have something to do here.
If you need a productive, functional computer without unnecessary show-off, then the Asus ROG Strix Z370-E Gaming is great option. The retail cost of the board at the time of publication of the article was about 16 thousand rubles.

New question
A small-sized, quiet and powerful computer is the dream of any user. The slots on ATX and EATX boards are mostly empty; one or two PCI Express, two or three SATA and one M.2 are used. So why buy a large tin box and put a huge motherboard in it if more than half of the space will be unused? That's right, there's no need. Powerful systems require small-sized but multifunctional motherboards. Such as ASUS ROG Strix X470-I Gaming

Equipment
The box is modest in size, four times smaller than a regular cardboard box for an ATX board.A standard set of accessories was included - instructions, stickers, a plug for the rear panel, a disk with drivers, SATA cables, an antenna, and a backlight connection cable. Yes, trends have already made their way into all form factors, and even if you can’t fit your little finger between the connectors on the PCB, there’s always room for a dozen LEDs.
Appearance
A full-size gaming board, compressed to Mini ITX dimensions, looks like this:
The installation is very tight. Everything that does not fit on the main board is mounted on separate small ones on top of each other. In this way, ITX mothers are similar to power supplies - in cheap and weak series everything fits on one piece of PCB, while in expensive ones entire blocks are placed on separate printed circuit boards to save space.
An interesting point is that the board under AMD processors. Socket AM4 took up a lot of space, but there is enough free space near the plastic mounting supports for large coolers.
All Ryzens are supported, including the 2700X with a TDP of 105 watts. It requires a powerful power converter, and it is here, right between the socket and the rear panel. There are six phases in total, controlled by the IR3555 controller.
A large heatsink is installed on the power transistors, shifted towards the rear panel so as not to interfere with the CO on the processor.
There are only two slots for RAM. The distance between the slots is enough to accommodate strips with large radiators. Modules with frequencies up to DDR4-3600 inclusive are supported.
Below the DIMM slots are the contact blocks for the second and third USB, two of the four SATA, and the indicator pins for the front panel of the case.
To the right of the ATX24 power connection socket there are four LEDs that display the stages of POST. This, of course, is not a two-digit indicator, but you can understand the progress of the process.
There is one PCI Express slot, with sixteen lanes, for a video card. They placed it at the very edge, which is not exactly a “classic” for ITX boards, but there is no other way.
Immediately behind the PCIEx16 is a multi-story structure, crowned by a heatsink for one of the M.2 slots. To the right of it are two more SATA. The ROG logo on the heatsink is illuminated, and power is supplied through a seven-pin connector.
There's a small one underneath PCB, on which an M.2 connector, an audio codec and three minijacks are mounted.
The second M.2 is on the back of the board, right under the system logic.
On the “ground floor” there is a chipset with a small heatsink, a TPU control chip and a “multi” (input/output controller) IT8760E.
This is how you can simply and reliably place both a drive with a radiator and a sound card in a minimal area, without interfering with the wiring for the chipset on the main board.
The rear panel is rather sparse - six USB different versions, HDMI and wired network, three audio card jacks and two high-frequency sockets for Wi-Fi antenna 802.11ac and Bluetooth.
At all wireless network It is much more common on ITX boards than on ATX. The reason for this selectivity is not very clear. Many users will be willing to give up wires if they have high-speed wireless with an external antenna that guarantees good reception in concrete boxes.
There are three four-pin connectors for fans, one of them can power a powerful consumer (SVO pump, for example). Next to it is a four-pin connector for a regular RGB strip and a three-pin connector for an address strip.
The UEFI BIOS menu has undergone minor reductions compared to that on full-size ATX boards.
The Ai Tweaker section still has many options for changing voltages, frequencies and timings.
The Advanced section allows you to configure in detail the operating modes of the processor, slots and interfaces.
Temperature monitoring is fully available, as is fan speed control.
The Tools section contains small but very useful utilities for setting up the system. You can quickly find out the contents of SPD RAM, view the video card data, “remember” the settings in one of the profiles, or vice versa, load them.
Overall I liked the board. The Ryzen 7 2700X processor was picked up without problems and worked as part of the gaming platform together with the GTX 1080 Ti Poseidon card for a week. I did not feel any disadvantages associated with the reduction in size. You can complain about the lack of quick start, reboot and BIOS reset buttons, but such boards rarely work on open benches, and there is no particular need for them.
Let's sum it up
ASUS ROG Strix X470-I Gaming is an excellent small-sized motherboard for the latest AMD Ryzen processors. It is great for building both play and working system in a small-sized housing. It will not be difficult for the power supply system to feed top AMD stones for Socket AM4, and the motherboard will not cause problems with installing large video cards. Everything you need for overclocking and tuning is in the BIOS, and perhaps the only objective drawback of the board is the small number of USB connectors, both on the rear panel and under the headers.The price is adequate - building a full-fledged motherboard in Mini ITX format using high-quality components is not cheap, and it is unlikely that other manufacturers can offer something similar in functionality and dimensions for less money.

- Small board dimensions
- Powerful power subsystem
- Supports the entire line of Ryzen processors
- Built-in Wi-Fi 802.11ac and Bluetooth modules

Form factor
The Asus ROG Strix X299-E Gaming board is made in a standard ATX form factor (305x244 mm), with 9 holes provided for mounting it into the case.
Chipset and processor socket
The Asus ROG Strix X299-E Gaming board is based on the new Intel X299 chipset and supports Intel Core-X processors (Kaby Lake-X and Skylake-X) with LGA 2066 socket.
Memory
To install DDR4 memory modules, the Asus ROG Strix X299-E Gaming board has 8 DIMM slots. If a 4-core Kaby Lake-X processor with a dual-channel memory controller is installed (Core i7-7740X and Core i5-7640X models), then 4 front memory slots are used, and the maximum amount of supported memory will be 64 GB (non-ECC Unbuffered DIMM) . When using Skylake-X processors with a quad-channel memory controller, all 8 slots can be used, and the maximum amount of memory supported will be 128 GB (non-ECC Unbuffered DIMM).
Expansion slots and M.2 connectors
To install video cards, expansion cards and drives on the Asus ROG Strix X299-E Gaming motherboard, there are three slots with the PCI Express x16 form factor, two slots with the PCI Express x4 form factor, a PCI Express 3.0 x1 slot and two M.2 connectors .
The first and second slots (counting from the processor socket) with the PCI Express x16 form factor are implemented on the basis of PCIe 3.0 processor lines and are PCI Express 3.0 x16 slots, that is, they can operate at x16 speed (depending on the processor used). These slots are designated on the board as PCIEX16/X8_1 and PCIEX16/X8_2.
The third slot (counting from the processor socket) with the PCI Express x16 form factor supports x8 speed and is a PCI Express 3.0 x8 slot, but in the PCI Express x16 form factor. Moreover, depending on the processor used, this slot can be implemented on the basis of PCIe 3.0 processor lines (in this case it operates in x8 mode), or it can be implemented on the basis of PCIe 3.0 chipset lines (in this case it operates in x1 mode). This slot is designated PCIEX8/X1_3 on the board.
The operating modes of slots with the PCI Express x16 form factor depend on which processor is used.
Let us recall that the Intel Core-X family includes processors with 16 PCIe 3.0 lanes (these are 4-core processors of the Kaby Lake-X family), as well as with 28 and 44 PCIe 3.0 lanes (Skylake-X family processors).
Let's start with the processor variant with 44 PCIe 3.0 lanes. In this case, all three slots with the PCI Express x16 form factor are implemented via PCIe 3.0 processor lines. The operating mode of PCIEX16/X8_1, PCIEX16/X8_2 and PCIEX8/X1_3 slots is as follows: x16/x16/x8. Moreover, in the case of a processor with 44 PCIe 3.0 lanes, you can use up to three video cards in CrossFire mode and two video cards in SLI mode.
In the processor version with 28 PCIe 3.0 lanes, only two slots (PCIEX16/X8_1, PCIEX16/X8_2) are implemented via PCIe 3.0 processor lines, and the PCIEX8/X1_3 slot switches to PCIe 3.0 chipset lines and operates in x1 mode, sharing with the PCI slot Express 3.0 x1. The operating mode of PCIEX16/X8_1 and PCIEX16/X8_2 slots is as follows: x16/x8. In the case of a processor with 28 PCIe 3.0 lanes, you can use up to two video cards in SLI or CrossFire mode, which are installed in the PCIEX16/X8_1 and PCIEX16/X8_2 slots.
In the processor version with 16 PCIe 3.0 lanes, again, only two slots (PCIEX16/X8_1, PCIEX16/X8_2) are implemented via PCIe 3.0 processor lines, and the PCIEX8/X1_3 slot switches to PCIe 3.0 chipset lines and operates in x1 mode. The operating mode of PCIEX16/X8_1 and PCIEX16/X8_2 slots is as follows: x16/- or x8/x8.
Two slots with PCI Express x4 form factor, a PCI Express 3.0 x1 slot and both M.2 connectors and are implemented via PCIe 3.0 chipset lines. Moreover, out of two slots with the PCI Express x4 form factor, only one slot operates in x4 mode and is a PCI Express 3.0 x4 slot. This slot is labeled PCIEX4 on the board. The second slot is designated PCIEX1_2 and operates in x1 mode, that is, it is a PCI Express 3.0 x1 slot, but in the PCI Express x4 form factor.
The first M.2 slot (M.2_1) supports PCIe 3.0 x4 and SATA drives with frame sizes 2242/2260/2280, while the second M.2 slot (M.2_2) is vertical and supports only PCIe 3.0 x4 drives with frame sizes 2242/2260 /2280/22110.
SATA ports
To connect storage devices or optical drives, the board provides 8 SATA 6 Gb/s ports, which are implemented on the basis of a controller integrated into the Intel X299 chipset. These ports support the ability to create RAID arrays of levels 0, 1, 5, 10.
USB connectors
To connect various peripheral devices, the board provides 8 USB 3.0 ports, 3 USB 3.1 ports and 4 USB 2.0 ports. All USB 2.0 and USB 3.0 ports are implemented via the chipset. 2 USB 2.0 ports and 4 USB 3.0 ports are located on the rear panel of the board, and the board has corresponding connectors for connecting 2 more USB 2.0 ports and 4 USB 3.0 ports.
USB 3.1 ports are implemented via ASMedia ASM3142 controllers. There are 2 such controllers on the board. One controller is connected to the chipset with 2 PCIe 3.0 lines. Based on this controller, 2 USB 3.1 (Type-A) ports are implemented, which are located on the rear panel of the board.
Another ASMedia ASM3142 controller is connected to the Intel X299 chipset with one PCIe 3.0 line, and only one USB 3.1 port is implemented on the basis of this controller. To connect this port, the board has a special vertical connector.
Network interface
To connect to the network, the Asus ROG Strix X299-E Gaming board has a gigabit network interface based on the Intel i219V PHY-level controller.
In addition, there is also a built-in dual-band (2.4 and 5 GHz) Wi-Fi module (802.11a/b/g/n/ac and Bluetooth 4.2). There are two antennas for this module.
How does this work
Let us remind you that the Intel X299 chipset has 30 high-speed input/output ports (HSIO), which can be PCIe 3.0, USB 3.0 and SATA 6 Gb/s ports. Some ports are strictly fixed, but there are HSIO ports that can be configured as USB 3.0 or PCIe 3.0, SATA or PCIe 3.0. Moreover, in total there can be no more than 10 USB 3.0 ports, no more than 8 SATA ports and no more than 24 PCIe 3.0 ports.
Now let's see how all this is implemented in the Asus ROG Strix X299-E Gaming version of the board.
The difficulty in this case is that for processors with different numbers of PCIe 3.0 lanes the implementation will be slightly different. Thus, when using processors with 28 or 16 PCIe 3.0 lanes, the PCIEX8/X1_3 slot switches to PCIe 3.0 chipset lines and operates in x1 mode, sharing with the PCIEX1_2 slot.
Let's start with the processor variant with 44 PCIe 3.0 lanes, when all slots with the PCI Express x16 form factor are implemented through PCIe 3.0 processor lines. In this case, only 40 PCIe 3.0 processor lanes are used for three PCI Express x16 slots. The PCI Express 3.0 x1 slot (PCIEX1_1) is shared with the ASMedia ASM3142 controller, on the basis of which a vertical USB 3.1 port is implemented. The PCIEX4 slot is shared with four SATA ports (SATA#5-#8), meaning the chipset's four high-speed (HSIO) ports are configured as either SATA ports or PCIe 3.0 ports. In addition, the SATA#1 port is shared with the M.2_1 connector, which supports both SATA and PCIe devices.
As a result, all 30 HSIO ports of the chipset are used.
The block diagram of the Asus ROG Strix X299-E Gaming board in the processor version with 44 PCIe 3.0 lanes is shown in the figure.
The processor version with 28 PCIe 3.0 lanes for two slots with the PCI Express x16 form factor uses only 24 PCIe 3.0 processor lanes. The PCIEX8/X1_3 slot switches to PCIe 3.0 chipset lines, which operates in x1 mode and is shared with the PCIEX1_2 slot. As a result, 30 HSIO ports of the chipset are used.
The block diagram of the Asus ROG Strix X299-E Gaming board in the processor version with 28 PCIe 3.0 lanes is shown in the figure.
The case with a processor with 16 PCIe 3.0 lanes is almost no different from the previous version. The only difference is in the organization of slots with the PCI Express x16 form factor based on PCIe 3.0 processor lines.
The block diagram of the Asus ROG Strix X299-E Gaming board in the processor version with 16 PCIe 3.0 lanes is shown in the figure.
Additional Features
This is not to say that the Asus ROG Strix X299-E Gaming board has a lot of additional features. Let's start with the fact that there is a POST code indicator and a power button.
But here are the reboot buttons, reset BIOS settings and the traditional MemOK button! not here. There are no switches on the board either. Partially buttons and switches replace jumpers. Thus, there is a jumper for resetting BIOS settings and a CPU_OV jumper, which allows you to set more high voltage power supply to the processor when overclocking it than is provided in normal mode.
Another feature is the presence of a connector for connecting a temperature sensor.
There is also a special Intel VROC Upgrade Key connector, which is a standard connector for boards based on the Intel X299 chipset. More information about Intel VROC (Virtual RAID on CPU) technology can be found in our article dedicated to new Asus boards based on the Intel X299 chipset.
The next feature of the board is the implementation of RGB backlighting. The backlight here is minimal; the black plastic casing on the rear panel is illuminated, for which a special translucent insert is made in it.
Located next to the processor socket decorative element in the form of a prism. This prism has a transparent window with the inscription ROG, which is also illuminated.
There are also connectors for connecting LED strip, and there is not one such connector, but three. Two of them are traditional four-pin (12V/R/G/B) connectors for connecting standard 5050 RGB strips with a maximum length of up to 3 m. Another connector is three-pin (5V/D/G). This is an addressable or digital connector for connecting an RGB strip with no more than 60 LEDs.
Other features of the Asus ROG Strix X299-E Gaming board include the presence of a connector for connecting a COM port, as well as the presence of two 3D_Mount mounting holes for attaching modding elements printed on a 3D printer.
Power system
Like most boards, the Asus ROG Strix X299-E Gaming model has a 24-pin connector for connecting the power supply. In addition, there is also a separate 8-pin ATX 12V connector and a four-pin ATX 12V connector.
The processor supply voltage regulator on the board is 8-channel and is controlled by a controller labeled Digi+ VRM ASP1405.
Cooling system
The cooling system of the Asus ROG Strix X299-E Gaming board consists of 2 radiators. One heatsink is designed to remove heat from the processor voltage regulator elements.
Another composite heatsink is designed to cool the chipset and the SSD drive installed in the horizontal M.2 connector.
In addition, to create an effective heat dissipation system, the board provides two 4-pin connectors for connecting CPU cooler fans, two 4-pin connectors for connecting case fans, two 4-pin connectors (AIO_Pump, W_Pump) for connecting a water cooling system, a separate 4 - a pin connector for connecting a drive cooling fan installed in the M.2 connector, as well as a 5-pin connector for connecting a Fan Extension card, to which you can connect additional fans and thermal sensors.
Audio subsystem
The audio subsystem of the Asus ROG Strix X299-E Gaming board is based on the Realtek ALC1220 codec. All elements of the audio path are isolated at the level of PCB layers from other components of the board and are allocated in a separate zone.
The rear panel of the board has 5 mini-jack audio connectors (3.5 mm) and 1 optical S/PDIF connector (output).
To test the output audio path intended for connecting headphones or external speakers, we used an external Creative E-MU 0204 USB sound card in combination with the Right Mark Audio Analyzer 6.3.0 utility. Testing was carried out in stereo mode, 24-bit/44.1 kHz. According to the test results, the audio path on the Asus ROG Strix X299-E Gaming board received a “Very Good” rating. The full report with testing results in the RMAA 6.3.0 program is posted on a separate page, followed by a short report.
