990FXA-UD7 Firmware

Five $160 To $240 990FX-Based Socket AM3+ Motherboards

Gigabyte's Hybrid EFI takes a beating from the marketing departments of its competitors, but we have yet to see any of its competitors’ claims against it demonstrated in a meaningful way. With Windows 8 on the horizon, suggestions that UEFI will be required could turn out to be true. Then again, we're still waiting for proof that UEFI will help slash the boot time of Microsoft's next-gen operating system.

Gigabyte’s traditional M.I.T. menu provides most of the settings needed to extract ultimate performance from any compatible CPU.

A full set of frequency, ratio, and voltage controls are present. But we were a little disappointed to find fixed-voltage mode missing for the CPU. Something else is also missing…

We find that missing something in the 990FXA-UD7’s “Advanced Features” menu. Multi-level Load Line control allows overclockers to overcome a phenomenon known as Vdroop, where CPU voltage is normally reduced under high loads.

Getting back to the M.I.T. menu, we find a fairly complete set of DRAM timings and clock strength controls in its “DRAM Configuration” submenu.
