The easiest way to overclock on the Intel platform is to simply change the frequency divider in the BIOS. To achieve the best overclock we try to stay with the timings that the XMP profile recommends. If we run into any issues we will bump up the voltage to see if we can get our system to boot and become stable.
The XMP profile puts this kit at 3200 MHz. In the BIOS I started moving up the frequency divider without changing the timings or voltage. I was able to get up to 3400 MHz without changing anything. At 3500 MHz the system would boot, but blue screen. So I decided to bump the voltage up to 1.45V and we not only had a successful boot, but also a stable system. So without changing timings we were able to get an extra 300 MHz out of this kit.
