Although it was the GUI that often scared new overclockers away from the BIOS, underlying limitations of that technology were the driving force behind Asus’ switch to UEFI. Nevertheless, we enjoy and appreciate the BIOS-like simplicity of the Sabertooth 990FX's UEFI interface.
Spanning three pages, Asus’ Ai Tweaker menu provides a wide range of clock and voltage controls that, unlike those of many competitors, actually work in a predictable manner. For example, when we disabled AMD Turbo Core to stability-test our maximum continuous overclock, the Sabertooth 990FX actually locked in the speed we set.
A little experimentation with Asus’ multi-stage Load Line Calibration revealed that the “High” setting kept our overclocked CPU very close to the continuous voltage we desired.
Asus-specific features are primarily limited to operational modes for its PWM, though all of the expected CPU, DRAM, and chipset voltage settings are also available.
Primary, secondary, and tertiary memory timings are individually selectable from Ai Tweaker’s DRAM Timing Control submenu.
