Socket AM3+/AM3 AMD 990FX ATX Motherboard

The MSI 990FXA-GD80 is an ATX motherboard built on the AMD 990FX chipset for Socket AM3+/AM3 processors. It supports 64-bit AMD Phenom II and Athlon II CPUs in a dual-channel DDR3 layout. Four memory slots accept up to 32GB of DDR3 at speeds from 800 to 2133MHz. The board provides six SATA 6Gbps ports, two PCI Express 2.0 x1 slots and one legacy PCI slot.

Builders keeping AM3+ platforms alive

This board suits enthusiasts maintaining or upgrading existing AMD Phenom II or Athlon II systems that rely on DDR3 memory and the 990FX chipset. It delivers eight-channel audio via the Realtek ALC892 codec and Gigabit Ethernet through the Realtek 8111E controller. Builders starting a new platform with newer sockets or different memory standards should look elsewhere.

Dual-channel DDR3 up to 32GB

The single specification that decides compatibility is the four-slot dual-channel DDR3 controller limited to 32GB maximum capacity. Verify that your processor, memory kit and cooler fit the AM3+/AM3 socket and DDR3 voltage requirements before purchase.

Questions about this item

What ATX case clearance and standoff pattern does the board need?

The board follows standard ATX dimensions and standoff locations; mount it in any case that accepts full-size ATX motherboards.

Which power connectors must be seated during installation?

Connect the 24-pin ATX main power and the 8-pin EPS CPU power near the socket; the system will not POST if either is loose.

When should the onboard CMOS battery be replaced?

Replace the included CMOS battery when the system loses date and time settings after power-off, typically after several years of use.
