AMD X399 chipset motherboard

The GIGABYTE X399 AORUS PRO motherboard is built on the AMD X399 chipset and uses the TR4 CPU slot. It supports DDR4 memory up to 128 GB across eight DIMM slots. The ATX form factor measures 30.5 cm by 24.4 cm.

High core-count desktop builds

This board suits builders who need many cores and large memory capacity for workstation workloads. It is not aimed at mainstream consumer platforms or small form factor cases. Buyers wanting a compact layout or standard desktop CPUs should look elsewhere.

Eight DDR4 slots for 128 GB maximum

The eight DDR4 DIMM slots allow a total of 128 GB of memory, the single specification that determines if this board matches your capacity needs. Populate all slots to reach the supported limit.

Questions about this item

How do I install this board in an ATX case and which standoff pattern catches people out?

Mount the 30.5 by 24.4 cm ATX board using the standard nine-hole standoff layout; the lower-right corner hole near the I/O shield is the one builders most often miss.

What component will need replacement first and how do I do it?

The metal battery holder on the board takes a standard coin cell; when the system starts losing time or BIOS settings after power-off, pop out the old cell and press a fresh one in.

Which thermal or power limit appears first during a long all-core workload?

The 8-pin and 4-pin CPU power connectors feed the VRM; under sustained load the VRM temperature rises first, so keep airflow over the heatsink area to avoid throttling.
