Now with the stock benchmarks completed, let us see how far we can overclock the Dark Z FPS memory kit. In stock configuration, this kit is advertised to run at a speed of 4000MHz at a voltage of 1.45v with CL16-18-18-38 timings. Unfortunately, due to the limitation of our test bench we were only able to get the kit to run at 3600MHz with CL16-18-18-38 timings.
Since we know we can’t get the Dark Z FPS to run any fast than 3600MHz we are going to try and tighten the timings a little. With only a slight bump of 0.01v to 1.46v, we successfully booted and stabilized the kit with timings of CL16-16-16-36.
With the overclock applied we only slight changes in read/write/copy speeds which are within a margin of error but we did see a reduction in latency of 0.8ns.
Re-running the SuperPi benchmark with the new timings we were able to shave off just over a second with a final score of 7 minutes and 5.8 seconds.
