Sorry about that, I (as usual
) was too in a hurry to help. There is however a compatible module CMX8GX3M2A2000C9 DDR3-2000 (XMS3-16000 9-10-9-27*2CH) 8GB Kit (2 x 4GB) 1.65v 9-10-9-27-2, but somehow I think you'd be better off if you get feedback from people using the same combo you are planning to buy. I did, and it was a good choice.
I'm using a 2x2 Kit, KHX1333C7D3K2/4GX. Very good timings at 1333, and XMP support, no issues so far. They don't come cheap, but for my gaming rig they are perfect. I wouldn't go for 6 or more Gb of RAM unless they are really needed.
