Benchmarks - Overclocked
As with all of our reviews, we pit the default speed system against the overclocked one in a head-to-head byte match. The only difference is that with our memory reviews we leave the base system (CPU, Chipset etc..) at default so that the only thing we are changing is the memory module. You can see this with the Sandra CPU Tests and at that point the only performance advantage is from increased memory performance.
There are different approaches to overclocking memory and while you may not get an extra 25FPS in your games the increased bandwidth and lower latencies can often unlock the potential for other system efficiencies or may have a net zero impact depending on what actually changed.
The effective overclock for these tests was 7200Mhz and to attain these clocks I used the XMP profile and simply raised the memory frequency.
Memory overclocking is a pretty arduous task of trial and error. As with most overclocking there is a balance that we want to maintain including the relationship between temperature, voltage and frequency. Given that your system memory also drives CPU performance it is not uncommon to see performance go down with an overclock that has been pushed too far or has a mismatched setting.
Much to my surprise there was very little change between the factory 6800Mhz and 7200Mhz. Given that this is only 400Mhz that would explain why the benchmark results didn't change much. Bandwidth did increase with a latency reduction and unfortunately, that is all I could get from these modules without running into stability issues.
