[freak200169]

Ive been wanting to oc system but have never messed with the timings. ive seen a cupple reviews that have been to DDR502 but am not sure what the #s (5-2-2-2) mean so i can set the accordingly. ex: which # is ras-cas, precharge..ect? also which this setup, air cooled, what do you think the max oc i would be able to achieve? if any? lol and i used PCMark04 and got 3431 for memory is that bad? thanx
