Our take on the Gigabyte GA-990FXA-UD3 (rev. 1.0)

The Gigabyte GA-990FXA-UD3 is a full-size ATX motherboard for AMD's AM3+ socket, built on the 990FX chipset. It stands out for its six SATA III ports, dual-card SLI and CrossFire support, and a legacy set of connections that includes FireWire and eSATA. It suits people keeping an FX-series or Phenom II build alive, or assembling one from spare parts. Against later AM3+ boards it lacks M.2, USB 3.1 and Wi-Fi, and its DDR3 memory tops out at 2000 MHz. Owners rate it as a stable, well-laid-out board for its era, with early revisions drawing complaints about VRM cooling under overclocking.

Pros
  • Six SATA III ports for drives and RAID arrays
  • SLI and CrossFire support on two PCIe x16 slots
  • FireWire, eSATA and legacy PCI alongside modern ports
  • Four DDR3 DIMM slots, up to 32 GB
  • Full ATX layout with room for large coolers
Cons
  • No M.2 slot and no Wi-Fi
  • DDR3 memory capped at 2000 MHz
  • AM3+ CPUs are long discontinued, so upgrade paths are closed
  • Early revisions have weak VRM cooling for high overclocks
  • No integrated graphics, so a discrete GPU is required

Questions and answers

Does this board support M.2 SSDs?
No. It has no M.2 slot, so storage goes through the six SATA III ports or a PCIe adapter card.
Which CPUs fit the GA-990FXA-UD3?
It uses the AM3+ socket and also accepts AM3 chips. That covers AMD FX-series processors and older Phenom II and Athlon II models.
Can it run two graphics cards?
Yes. It supports both SLI and CrossFire across its PCIe x16 slots, though the lanes split when both are populated.
How much memory can it take?
Four DIMM slots hold up to 32 GB of DDR3, with official support up to 2000 MHz.
Does it have built-in Wi-Fi?
No. Networking is a single Gigabit Ethernet port, so Wi-Fi needs a PCIe or USB adapter.
Is it good for a modern gaming build?
No. It is tied to discontinued AM3+ CPUs and DDR3, so a current socket board is the better base for a new build.
Where is the Gigabyte GA-990FXA-UD3 (rev. 1.0) cheapest?
At Newegg, for $479.43, as of our latest check.
