Corsair Dominator TWIN2X2048-8500C5DF

"I was amazed at the shear brute force with which these Dominator sticks churned through our benchmarks. Whether talking about stock performance or overclocking prowess, the power, strength and flexibility of Corsair’s premiere line of memory modules are simply amazing. If you can swallow the price tag, these bad boys will reward you with a lot of benchmark and gaming ass kicking."

"To sum it all up, you could say that Corsair is a very safe way to go when it comes to compatibility between different motherboard manufacturers. The overclocking potential is undeniably there and if you can access high voltages, you can reach both high frequencies and fast latencies. The included fan, which can also be purchased separately and used for most other memory models and brands, is of high quality and functionality. The price of this kit in particular is $370 at the moment, but it doesn't seem to be updated in all stores as the exact same memory (8500C5D) costs about $290 separately and the fan costs about $20, which adds up to $310 - a few tens of dollars above the corresponding memory from other manufacturers."
