Corsair Dominator GTX Series PC3-18000 4GB Kit - Overclocking

PC3-18000 translates to a massive 2250MHz DDR which is to date the fastest memory kit we've looked at, outperforming the two recent PC3-17600 kits from G.Skill and A-DATA we saw recently which carry with them an already impressive 2200MHz DDR.


While we would tend to be wary of our system being able to achieve this massively high clock rate, we did have some luck overclocking a 2200MHz DDR kit to around 2250MHz DDR in the past. Since we knew our testbed was capable of those speeds, the only reason we wouldn't be able to achieve the rated speed today would be because of the Corsair modules.


The good news is that the Dominator GTX modules played extremely nice and getting to 2250MHz DDR (or 2258MHz to be exact) wasn't an issue at the default 8-8-8-24-2T timings.

With that achieved with no real problems, as always we also took the time to see how overclocking went. Now, I have to be honest here. To say I expected anything over 2250MHz DDR would be a flat out lie; but it's my job and it was time to see what was going on with these modules.




You can see the validation here.


Slowly working our way up to 2300MHz DDR, we continued to boot into Windows and were able to run wPrime. Taking a bit more time and moving even more northward, we eventually found the sweet spot at a massive 104MHz DDR above its stock clock, giving us a total of 2354MHz DDR. This is just an insane number and we hope that when it comes to testing we see some performance improvements with the kit.


Important Editor Note: Our maximum overclocking result is the best result we managed in our limited time of testing the memory. Due to time constraints we weren't able to tweak the motherboard to the absolute maximum and find the highest possible FSB, as this could take days to find properly. We do however spend at least a few hours overclocking every motherboard to try and find the highest possible overclock in that time frame. You may or may not be able to overclock higher if you spend more time tweaking, or as new BIOS updates are released. "Burn-in" time might also come into play if you believe in that.
