PC2-6400 or PC2-8500? Tags: Memory RAM Product Last response: January 8, 2010 7:34 PM in Memory Share Bobypoisson January 8, 2010 7:02:27 PM I currently have a 32 bit windows XP OS and I will upgrade to a 64 bit Windows 7 OS and at the same time, I will get a 8 gig set of RAM. My motherboard, Asus M4A78 PRO, supports 1066 mhz RAM but is the performance difference with 800 mhz RAM worth the price? My CPU is a AMD Phenom II X4 940 and my graphics card is an Asus EN8800GTX. Do you have any suggestion of what RAM I should get? Will I be able to overclock my system?
