When I originally built my rig, I had a good overclock going, but when I replaced my motherboard, video card and RAM, it stopped working so well. The CPU still overclocks, but it doesn't even reach 3.0GHz, it dies around 2.8GHz. It was originally an e6550 @ 2.33GHz, and I know the problem isnt my motherboard as the motherboard was reviewed as a good overclocker and has tools built into the bios for overclocking.
It seems like my problem is my RAM as it is DDR2-667 and My current FSB is 400. Would it be dangerous to push it anymore? should I just buy more RAM with a higher FSB rating?
