We are using the Asus P8Z77-V motherboard to test today's memory kit. It supports RAM from many manufacturers and gives us a large amount of flexibility to tinker with memory multiplier, base clock and timings settings.
Thanks to the fully-functioning XMP profile, we had no problems configuring the memory kit for use at its 1600MHz frequency and correct timings.
CPU-Z gives visual confirmation that this 32GB RipjawsX memory kit supports an XMP-1600 configuration.
Our system's CPU-Z validation can be found here.
We increased the memory voltage to a BIOS setting of 1.700V and relaxed the timings to 11-11-11-30-3T before aiming to improve the memory frequency. Increasing the motherboard’s ‘DRAM Current Capability’ to 130% and ‘DRAM Power Phase Control’ to Extreme allowed us to push the memory as far as possible.
Our initial attempts gave much success as we breezed through the 1,800MHz and 1,866MHz memory dividers. 2,000MHz was a step too far for the 1,600MHz RipjawsX memory kit, so we had no choice but to aim for more precise tweaks.
Backing down to the 1,866MHz divider and increasing the base clock by 1MHz increments gave no luck; the kit wouldn't post once its frequency passed 1,866MHz.
With our stable overclock frequency achieved, it was time to see how tight we could get the timings.
We were able to achieve complete stability with timings of 10-10-10-27-2T, but anything tighter and the system wouldn't post.
Increasing this high-capacity memory kit's frequency by an entire divider left us impressed with our overclocking attempts, especially given the fact that only a small relaxation of the timings was required.
Our final overclocked configuration was 1866MHz with 10-10-10-27-2T timings and a voltage of 1.700V.
