GIGABYTE GA-990FXA-UD3 R5 rev. 1.0 AMD motherboard

AM3+ motherboard for AMD FX systems

This ATX board uses the AMD 990FX chipset and supports FX, Phenom II, Athlon II and Sempron 100 Series processors in the AM3+ socket. It is built for desktop builders who want a standard layout with SATA 6 Gb/s and USB 3.0 connectivity. The design targets enthusiasts assembling a high-performance AMD platform.

Check CPU socket and DDR3 memory speed

Verify that your processor fits the AM3+ socket and matches the listed FX, Phenom II, Athlon II or Sempron 100 Series families. The board runs DDR3 at 1066, 1333, 1600, 1866 and 2000 (O.C.) MT/s, so confirm your modules are rated for the desired speed. Ensure your case accepts ATX dimensions and that the power supply provides the required 24-pin and 8-pin CPU connectors.

Thermals noise and power draw in normal use

The 990FX chipset and voltage-regulation area are cooled by heatsinks without active fans, so noise depends on the CPU cooler and case airflow you choose. Power consumption scales with the installed processor and memory configuration; the board itself adds only the chipset and VRM overhead. Adequate case ventilation keeps temperatures stable during typical workloads.
