The easiest way to overclock memory 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 3600 MHz. In the BIOS I started moving up the frequency divider without changing the timings or voltage. I was able to get up to 3800 MHz without changing anything. Then I had to start changing the voltage to get a stable boot. I was actually able to boot all the way up to 4000 MHz, but the kit was not stable. Anything over 3800 MHz was not stable, even if I upped the voltage to 1.45V. 3800 MHz with no voltage or timings change became our final overclock.
