I got some Gskills installed today, they are the F3-17000CL9-2GBXMD models, basically the step down from these, but at 1.5v and 9-11-9-29-2t. Using the XMP profile they were set at 9-10-9-28-2t. I am running two kits for 8gb total and had to increase the voltage to 1.55v. All I can say is that Gskill is selling some impressive ram kits right now. Here is a screen shot:



I haven't tried to tweak them since I just got them installed, but for $200 ($99.99 for each kit), I think they are pretty impressive.
