i have an e6750 that i am oc'ing on my gigabyte p35-ds3 board. it was 3.2ghz stable without changing the voltage, but i heard 3.4 was approachable without changing the voltage. i just went up to 3.3 and when i booted up, cpu-z says my g.skill pc2-6400 is 412.6mhz and 5-6-6-16...although it's rated at 400mhz 5-5-5-15 (which was perfect for a 3.2ghz oc). what does this mean exactly? should i go back to 3.2?
