CORSAIR XMS 4GB (2 x 2GB) 240-Pin DDR3 SDRAM DDR3 2000 (PC3 16000) Desktop Memory

I have these operating at 1600mhz @ 7-7-7-19 @ 1.58v. I have these on a P67 MB with an i7 2600 CPU. No complaints at all. A lot greater than other brands as I had no trouble receiving these to run at specified speeds and timings (and better). I purchased these particularly to run @ 1600mhz with tight timings as I wanted voltage lower than 1.60v (per Intel). Cost was a little greater than other 1600mhz memory, but these are not 1600mhz chips. Functions on a number of Gigabyte P55 and P67 boards.

Decent price / speed none. This ram is faster than the necessary for my board (GIGABYTE GA-870A-UD3 AM3). Utilizing this ram and some water cooling, I was able to over clock my 3.5 Ghz X4 BE to 4.two Ghz.
