The BIOS

The full featured UEFI BIOS on all the ASUS LGA1155 boards is nothing short of impressive. It is full featured, and can do everything and much more than any traditional style BIOS such as screenshots and overclocking profiles. The ability to use a mouse in the BIOS is a key feature that new users will find handy, as the UEFI GUI makes using the BIOS a hassle no more. ASUS claims that boot times are improved as well, and we found the BIOS to be pretty snappy.

The BLCK Skew is unique to the ROG boards, and a feature that benchers cannot live without. What it does is allow a delay for the CPU and PCH and PCI clock signals to align correctly. Due to the different positions of these components on the boards(further away from each other) their clock signals need to be delayed to give the overclocker the most optimum BLCK frequency.

GPU DIMM POST allows the user to monitor their GPU from the BIOS, saving time when benching to make sure everything is ok before boot.

We did face an annoying issue during testing – some of the gaming-grade mice we used (Razer and Steelseries) exhibited strange issues or did not work at all in the UEFI Bios.
