Looking at overclocking my system but I'm getting a bit confused, and some guidence would be great.

If I do over clock the system does the memory have to be over clocked?

My specs are:

Q9450
Asus P5Q Pro Turbo
Corsair XMS2 DDR2 PC2-8500C5 (4GB) Twin sticks
BFG 8800 GTS 640MB
OC2 GameXstream 600w Slinet SLi
Zalaman Cooler
