why are you guys talking as if RAM effects your CPU overclock.
It doesn't matter what the hell kind of RAM you got, that's why theres memory dividers to keep your memory running down at around 200 while you crank up the HTT for your CPU.
With good quality 1GB RAM you can take it not only .4GHz over, but (If you're lucky) 1.0GHz over
RAM does NOT effect that....his CPU will overclock as far as it can go based on what week it was made, luck of course is the biggest part of it, but RAM does NOT effect your CPU overclock, they are two completely seperate things.
Only time you need to worry about getting good RAM is if you want to OC your RAM as well and have it follow your CPU up when raising the HTT to get the most of out of your system
