OCC has published a review on the Corsair Dominater 2x2 GB DDR3 1600 Cas 8

Much like with the Kingston memory the Corsair Dominators were able to make it above the 2000MHz mark. However, they didn't make it quite as far. The Dominators were able to reach speeds of 2026.6MHz with timings of 9-9-8-24. With Corsair's DHX cooling, these modules should be able to run at these settings without any problems. I know some of you skeptics are wondering why you'd need memory that runs at 2000MHz. The answer is you really don't, but having memory that can achieve these higher speeds is a good thing. This means you'll be able to overclock your CPU farther then you would have been able to with a generic memory kit.
