So far I have read that you can overclock a Q6600 to 3.6GHZ on air. In my system I dont want to deal with liquid so I wanna stick with air cooling. So basically I was wondering would I be able to hit that speed with DDR2 800 without overclocking the ram or should I go with 1066? Also, I was wondering if I would get better performance if I bought 1066 and underclocked it to run at tighter timings? I plan on getting 4x1GB sticks. Price is not a large consideration here either.
