Thanks...

I think you need to decide on 2x1 or 2x2. The best OCing 2x2GB kits are Dominator, Mushkin Ascent, and GSkill 1100 Pi. If you go 4x1, will your mobo let you take advantage of the good Micron stuff and do you want the reliability problems that accompany D9GMH? I love my Team Xtreem, but right now it's somewhere between here and Taiwan on its way back from RMA...:(
