The ASUS UEFI BIOS are by far one of the most effective and clean UEFI BIOS that have come across the Legit Reviews test bench so far. When you first boot up either of the ASUS Republic of Gamers motherboards you are presented with the Extreme Tweaker page within the Advanced mode. Here we have, or can jump to all of the pages that we will need for overclocking. The first option on the Extreme Tweaker page is the CPU Level Up. You can set you Intel Core processor to either 4.2GHz or 4.6GHz. Beleow the CPU Level Up feature we can manually set the Bclk, Maximum Turbo ratio, Memory Frequency, as well as the iGPU Max Frequency. This particualar shot is from the ASUS Maximus IV Extreme-Z. If you remember back to the layout page, there is no video out on the Extreme-Z, yet we can still tweak the iGPU!

Scrolling down the Extreme Tweaker page we can see the sub-pages for the DRAM Timing, GPU DIMM Post, CPU Performance Settings, as well as the DIGI+ VRM/Power control. Below the selection of sub-pages we begin to see our Voltage Options. The ASUS Maximus IV Extreme-Z and the ASUS Maximus IV Gene-Z should has enough voltage options for any level of overclocker out there.

One little tidbit I noticed about the ROG BIOS (aside from the colors which match the ROG Red and Black) was that the system doesn’t default to the EZ Mode. Instead it heads directly into the Extreme Tweak and if you want the EZ Mode you have to switch to it.
