Cinebench R15
We used the ‘CPU’ test built into Cinebench R15 to measure the effect that system memory has on computational performance.
Super Pi 32M
We used the '32M' test in Super Pi to analyse the effect that system memory has on single-threaded performance.
Performance in CPU-heavy tests is close between all of the kits. Cinebench penalises Corsair's Vengeance LPX set for its higher latency, although we must remember that the kit is sold as a 2800MHz part and the 3000MHz XMP configuration is a welcomed ‘bonus'.
Super Pi typically shows preference for memory frequency over timings, and that is proven in our test results. Performance differences for each kit are within 0.6%, although Kingston's modules do repeatedly outperform the other two by three seconds. The result could be tied to enhanced tertiary timings, or it could simply be an interpretation of Super Pi's benchmarking accuracy.
I AM IN IT TO WIN IT GREAT MEMORY
Thanks KitGuru – been struggling to work out how to get my Corsair 4 x 4GB 2800MHz to play ball in my Rampage V – just the article I needed to get my head around the XMP settings 🙂
Is there any real difference between DDR3 and DDR4 that would justify to get DDR4 for a new rig right now despite the difference in price ?
You don’t have a choice if you plan on building an X99 system. It only uses DDR4 memory modules and you can’t use DDR4 on Z97 and older mainstream motherboards. But if you mean Z97 with DDR3 vs X99 with DDR4, then their is real and significant performance difference.
yes, I meant Z97+DDR3 vs Z99+DDR4, especially for games.
