VapoChill LS / Mach II GT with new setup?

Finally unpacked some computer stuff and set up my rig, I just replaced my 8gb of corsair xms2 with 8gb of OCZ Blade series low voltage 1150 , absolutely amazing memory, I didnt do any tweaking what so ever, and was able to hit 4.2ghz right off the bat, no adjustments to voltage on CPU or mem, I will mess around with this come the weekend and try to push 4.8ghz! Think Ill keep this q9650 for another month then go "big boy status" and step up to the I7!
