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.
Since the boards all have vastly superior profit margins, your statement is misleading. Why is everyone too afraid to reveal the truth about motherboard pricing?
A comparison of the time between the power button being pressed and the installed bootloader starting would be very interesting to me. I was thinking it might be easiest to measure this by having no OS on the boot media and measuring the time to the "please insert boot media" message, but I'm sure you can think of other ways of doing it.
I'm also informed that on some boards the boot time varies dramatically dependent on whether any Overclocking is enabled, as compared to the stock settings - that would also be worth knowing.
not anymore, asrock is no longer affiliated with Asus and is owned by Pegatron Corp.
