ASUS Rampage IV Extreme – Easy Overclocking Guide

Ed- Originally written by Raja in ASUS North America, this is currently one of the most popular threads in our Rampage forum. If you’ve just bought a new ROG X79 board and want to get up and running quickly, this OC guide will certainly help!

Easy Overclocking Guide

This guide is aimed at beginners who wish to set up the R4E with a manual overclock rather than use the preset profiles. We’re going to identify the key settings to get you up and running.

• Enter UEFI (BIOS) and navigate to the Ai Tweaker Menu:

• Set Ai Overclock Tuner to Manual
• Set the desired core ratio (multiplier) for the CPU. We recommend 43~45X depending upon your cooling.

• Set memory frequency to the specified speed of your memory modules (assuming they are 1.5V).

Then simply press F10 and save and exit UEFI.

This will get you up and running quickly. After this you may with to run a stress test to check the system is stable before you begin tweaking voltages.

The only voltages you may wish to change manually are CPU Vcore, DRAM Voltage and VCCSA. There are two ways of changing Vcore, the first is Manual mode, which allows you to set a static voltage that does not change with processor frequency. The second and more desireable operating mode is Offset Mode, for which we have a guide here:

We recommend that you stay under 1.40Vcore for long term use, and most CPUs should give you 4.3GHz quite happily under that level of voltage.
