Gigabyte Z790 Eagle AX Motherboard Details
The Gigabyte Z790 Eagle AX box includes the motherboard, the user's manual, two Wi-Fi antennas, two SATA cables, M.2 screws, and one pack of thick and thin M.2 rubber pads. Use the thick black pad under double-sided M.2 SSDs. For single-sided drives, stick the thin gray pad onto the thick one first. Only the M2A_CPU slot has a heatsink. Remove the protective film from its thermal pad and from the bottom of the heatsink before you put it back.
Memory is split into two channels: DDR5_A1/A2 and DDR5_B1/B2. With two modules, Gigabyte recommends the DDR5_A2 and DDR5_B2 sockets. A single module should also go in DDR5_A2 or DDR5_B2, although Dual Channel mode can't run with only one module. For best results, use matched modules of the same capacity, brand, speed and chips. The BIOS detects memory specifications automatically.
Each of the six fan and pump headers is 4-pin and rated at 2A and 24W. SYS_FAN2B has no Sense pin, and SYS_FAN2A and SYS_FAN2B share synchronized settings. The two addressable LED headers take standard 5050 strips rated up to 5A (5V), with a maximum of 1000 LEDs. Connect the strip's triangle-marked power pin to Pin 1, because a wrong connection can damage the strip.
Gigabyte recommends a power supply of 500W or greater. If the 8-pin 12V CPU power connector isn't connected, the computer won't start. Four status LEDs (CPU, DRAM, VGA and BOOT) help with troubleshooting. A lit CPU, DRAM or VGA LED means that device isn't working normally. A lit BOOT LED means the system hasn't reached the operating system yet.
Q-Flash Plus updates the BIOS while the system is in the S5 shutdown state. Save the BIOS file to a USB drive, plug it into the dedicated USB 2.0 port on the back panel, and press the button. The QFLED blinks while flashing and stops when it's done. The RST_SW button and RST jumper can be remapped to other tasks with the BIOS "RST_SW (MULTIKEY)" setting.
During POST, press Delete to open BIOS Setup, F12 to open the one-time Boot Menu, or End to go straight to Q-Flash. You can reset the CMOS by shorting the CLR_CMOS pins, or by removing the CR2032 3V coin battery for one minute. Afterwards, select Load Optimized Defaults in BIOS Setup.
The LAN port has two LEDs. The speed LED is orange at 2.5 Gbps, green at 1 Gbps, and off at 100 Mbps. The activity LED blinks while data is moving. The HDMI port supports Dolby TrueHD, DTS HD Master Audio and 7.1-channel LPCM at up to 192KHz/24bit. To set up 7.1-channel audio, assign the front panel line out as the side speakers in the audio software.
To install Windows on a RAID volume, you first need to load the Intel RST VMD Controller driver from a USB drive during setup. Note that an M.2 PCIe SSD can't be in the same RAID array as an M.2 SATA SSD or a SATA hard drive. After Windows is installed, GIGABYTE Control Center offers to download the drivers, as long as Gigabyte Utilities Downloader is enabled in the BIOS.
