Since the time of launch of Haswell CPUs, the debates on RAM frequencies above 1600 MHz supported by the Processors became prominent. Few said that 1866 MHz or higher frequency doesn’t help, the other half said that it does have a significant impact. And then suddenly out of the mist, Corsair declares something quite unexpected which would definitely shock both the parties and their preference.

Haswell benchmarks show: High Frequency RAMs give boost in Gaming

Corsair suddenly releases some gaming benchmarks that astonished the non-believers of the fact that higher frequency RAM modules don’t affect game-play performance. They obviously did this because Haswell-E along with X99 “Welsburg” chipset that would have support for DDR4 DIMMs and the future owners of X99 platform would definitely stress on high quality and performance RAMs. This might be a marketing strategy for their future products. Anyways, they did break a quite big misconception that few gamers and tech enthusiasts had about the RAM frequency affecting game-play, but one may recall that Kaveri APUs’ performance were significantly improvised using high-end frequency RAM and AMDs own Gaming RAMs lineup with high frequencies like 2400 MHz. Corsair’s benchmarks were provided by a Swedish over-clocking site, which are quite interesting.

Testing was done with 4 types of RAM modules with different Frequencies. 1600 MHz, 1866 MHz, 2133 MHz and 2400 MHz, all provided by Corsair. The 0% baseline is the 1600 MHz non OC frequency. And it is evident from the benchmarks that the difference between 1600 MHz and 1866 MHz is quite noticeable. This is quite an astounding fact, since you are getting better game-play performance with just a better RAM with higher frequency.

The graph is a bit old-school and the CPU used to be an over-clocked one at 4.5 GHz, the frame rate difference between the two modules is a  quite impressive number of 9 FPS which is remarkable considering only RAM is added. But we would again like to prompt that this could be a marketing strategy by Corsair. But if it isn’t, then go hurry up and get an 1866 MHz module. But one has to also rely on the other hardware like the motherboard to support the OC frequency of 1866 MHz and above. So we suggest the upgrade only if you can avail the feature and not something that would prove to be a waste of money. So what’s your opinion on the RAM DIMMs with O.C’ed frequency?
