Motherboard Layout

The AX370-Gaming 5 motherboard features the matte black PCB with white plastic overlays and black heat sinks common to the current generation of GIGABYTE AORUS line boards. The plastic overlay sits over the upper VRM heat sink and rear panel components, as well as over the audio components, functioning to spruce up the board's aesthetics as well as offering protection for the covered components. The board's ATX form factor provides more than enough surface area to house the designed-in integrated features, as well as giving the board compatibility with most available consumer enclosures

The board back completely free of components with the exception of small capacitors sitting underneath the CPU VRMs and power circuitry sitting in the center hole of the CPU backplate. If your cooler requires replacement of the stock back plate, the center CPU circuitry could become problematic if the backplate does not have a hole in its center to compensate.

GIGABYTE integrated a 10-phase (6+4) digital power system into the AX370-Gaming 5, capable of providing more than enough power to the CPU for whatever torture tests you choose to throw at it. Designed with the GIGABYTE Ultra Durable power system, the board includes IR digital power controllers and PowIRstage ICs, Server Level Chokes, and Durable Black capacitors is its digital power system design. The CPU VRMs are cooled by two standalone aluminum heat sinks to the top and right of the CPU socket.

The board's 8-pin ATX12V power connector is located to the upper right of the CPU socket, in between the two VRM heat sinks. This is also a 4-pin system fan header just above the ATX12V connector.

GIGABYTE designed the board with a single PCIe x4 M.2 slot in between the primary and secondary PCIe x16 slot with the port sitting just above chipset heat sink. The slot accommodates M.2 cards up to 110mm in length and is keyed for M-key type devices with standard SSD, PCIe x2, and PCIe x4 type M.2 drives supported. Note that the M.2 and U.2 ports share bandwidth, resulting in the M.2 port being disabled with a U.2 device plugged into the integrated port.

The board has a total of four DIMM slots with Dual Channel memory mode active with modules in slots 1 / 3 or 2 / 4. The board supports up to 64GB of memory running at a maximum speed of 3200MHz. Note that memory speeds above 2400MHz are considered overclocked speeds and are outside of the official AMD stock memory speed specifications. The memory slots are steel reinforced for extra strength. Further, GIGABYTE integrated RGB LEDs in between the slots, configurable via the UEFI or the RGB Fusion Windows applet.

Directly below the memory port block are multiple USB 3.0 / 3.1 Gen1 headers, the 24-pin ATX power connector, and two 4-pin system fan headers. The acrylic overlay directly below the DIMM slots glow when the board is actively powered, in line with the RGB LED settings from the UEFI or Windows RGB Fusion applet.

To to right of the DIMM slots are the CMOS reset, board reset, power, and OC buttons, and the CPU primary (CPU_FAN) and CPU secondary (CPU_OPT) 4-pin fan / power headers. The 3-pin header just above the CPU fan headers is likely a debug header used for factory-based board validation testing. The OC button enables BIOS-assisted automated overclocking of the board, based on factory configured settings.

The AMD X370 chipset is covered by a low profile chromed black heat sink with an AORUS overlay. In addition to the PCIe x4 M.2 slot, the board features four SATA III ports, two SATA-Express ports, and a U.2 port in the port block directly below the chipset heat sink. The SATA-Express ports can be used individually to add another four SATA ports to the system. All SATA ports are usable in conjuction with the a drive seated in the M.2 port and do not share bandwidth with other board integrated devices or ports. However, the M.2 and U.2 ports share bandwidth with the M.2 port automatically disabled when a device is plugged into the U.2 port.

The board contains a total of six PCIe slots – three PCIe x16 slots and three PCIe x1 slots. The PCIe x16 slots can be used in x16 / 0 / x4 or x8 / x8 / x4 modes. Note that the third PCIe x16 slot operates at x4 mode only if no cards are installed in any of the PCIe x1 slots. The third PCIe x16 slot operates at x1 speed with a card installed to PCIe x1 slot 1, and at x2 speed with a card installed to PCIe x1 slot 2 or 3.

The board's integrated audio components are covered by a white plastic overlay just above the PCIe ports with the AMP-UP Audio logo stamped into its surface. The audio subsystem lives on an isolated PCB to minimize line-noise and distortion caused by other integrated components. The PCB separator line illuminates according to the color scheme configured through the UEFI or the Windows RGB Fusion applet. To ensure balanced audio performance using headphones or external speakers, GIGABYTE designed the audio subsystem with dual Realtek ALC 1220 CODECs, dual smart headphone AMPs, Nichicon Audio capacitors, and support for Soundblaster X-Fi MB5 technology.

GIGABYTE integrated support for connecting an RGB LED strips directly into the board using the RGB LED headers located in the upper left quadrant of the board. Connecting an RGB LED strip to the header synchronizes the LED strip color and activity with that of the motherboard's integrated LEDs. The board is shown with an external RGB strip connected to the header in the board's upper left quadrant (by the CMOS battery). Notice that the board has multiple integrated RGB zones (in addition to the RGB header) – around the CPU VRM heat sinks, lining PCIe x16 slots 1 and 3, integrated into the underside of the board's audio separator line, in between the DIMM slots, and the underneath the acrylic overlay located just under the DIMM slots.

In addition to the RGB LED header, the front panel audio header, LED Demo header, the BIOS Select and DualBIOS switches, and a trusted module port header. The 5-pin LED header supports use of either a 4-wire RGB LED strip or a 5-wire RGBW strip with the board. The BIOS Select switch forces the board to boot using the main BIOS (in the 1 position) or the backup BIOS (in the 2 position). The Dual BIOS enable switch enables the board's Dual BIOS functionality in the 1 position, or disables it in the 2 position (forcing the board into single BIOS mode).

Along the mid and lower left side of the board are the trusted module port header, the CMOS battery, the USB 2.0 headers, the two-digit diagnostic display, the system status LEDs, 4-pin system fan and pump headers, a temperature header, the front panel header, and the CMOS reset jumper. The Status LEDs give a visual indicator for troubleshooting issues with LEDs illuminating to indicate a malfunctioning device. LEDs show status for the CPU, memory, PCIe x16 slots, and the BIOS. The 2-digit diagnostic display can be used for debugging system issues during system initialization. The displayed debug codes can be decoded using the table from the motherboard manual. The 4-pin water pump header can be used to power and monitor a standard 12V water pump – an AIO cooler's integrated coolant pump or a pump integrated into a DIY loop.

The AX370-Gaming 5 motherboard contains the following integrated ports in its rear panel assembly: a hybrid PS/2 port, two USB 2.0 ports (yellow), four USB 3.0 ports (blue), four USB 3.1 10Gbps ports (red) – three Type A and one Type C, dual RJ-45 ports – an Intel I211-AT GigE port (to the left of the audio ports) and a Rivet Networks Killer E2500 GigE port (above the USB 3.0 ports), an S/PDIF digital audio output port, and five analogue audio output ports. The USB 3.1 Type A port located about the Type C port and the Type C port are tied by the ASMedia controller, while the two USB 3.1 Type A port to the left of the audio ports are tied to the AMD X370 chipset controller.
