DX79TO Firmware

Six $200-$260 LGA 2011 Motherboards, Reviewed

Intel’s atypical GUI is easier to use than a number of competing firmware implementations, though it does take a few minutes to master. The main “Performance” menu, for example, shows many settings, but only a few are selectable.

Host Clock Multiplier refers to the setting formerly known as a boot strap on older LGA 775 boards. This sets the ratio between the X79 PCH and CPU base clock. Other settings include base clock, CSA voltage, I/O and PLL voltage, and PCH core voltage.

CPU core voltage is found in the DX79TO’s Processor Overrides submenu, along with V-Droop control, current limits, and Turbo Boost ratios. Setting Runtime Turbo Ratio to Enable allows a single Turbo Boost multiplier to be adjusted from within Windows while reducing firmware GUI ratios to a single setting. We used the 47x ratio with a slightly underclocked 98.88 MHz BCLK to reach a stable 4.616 GHz overclock.

The DX79TO’s Memory Overrides submenu includes memory voltage and multiplier, plus primary and secondary timing controls.
