Corsair Dominator Platinum 3300MHz DDR4 Memory Overclocking:

Corsair DDR4 3300MHz 16GB Kit

Can Corsair’s fastest memory kit available be overclocked beyond 3300MHz? We wanted to see if there was any overhead left in the Corsair Dominator Platinum 16GB (4 x 4GB) 3300MHz DDR4 memory kit (CMD16GX4M4B3300C16), so we tried overclocking it by raising the baseclock on our Intel Core i7-5960X Haswell-E processor up from 103.2MHz to see if we could get more than 3300MHz on the DDR4 DRAM.


We know that Corsair is reaching the limits of what is possible today at 3300MHz, but we were able to squeeze out a little extra by raising the BCLK of the processor up to 104.2MHz. This extra MHz was able to give us a final DDR4 clock speed of 3335MHz with CL16 timings.  Not too bad! Our system failed to post when trying beyond 104.2MHz, so this is about the maximum for this memory kit with 1.35V.


We were able to get 3300MHz stable with a 1T command rate on the ASUS X99 Deluxe motherboard that we used for testing as well. By tightening the command rate we were able to improve the latency and copy test results in AIDA64.


The Corsair Dominator Platinum 16GB 3300MHz DDR4 memory kit might be the fastest memory kit sold by Corsair, but there is still some headroom left in it for enthusiasts looking to tighten timings or overclock the kit. It should be noted that Corsair recommends the ASUS X99 Rampage V Extreme motherboard when using this memory kit. We were using the ASUS X99 Deluxe, so your results might be better on a board that is better optimized for overclocking. Nonetheless our results are still impressive and even more so if you consider the fact that we aren’t using the recommended platform.
