I have always had better responses by clocking the CPU and keeping the RAM normal and cool. I am a very strong believer in Software related speed and find a format/Re-ghost every 3 months keeps my baby at full speed.
You would be suprised.
I have never been sucessfull clocking RAM with 3 different boards and chipsets. I useually get crashing when upping the RAM.
BTW How you doing Adam??
