the ram i'm using came from a 2-3 year old alienware. it's default clock rate was 166mhz and i OCed it to 200mhz. right now fsb is 220 and the multiplier is 10x with the memory at 200mhz like I said above, and it seems to be stable, i've had prime95 running for about 12 hours with no errors and I've run memtest in the past for many hours with no errors. it seems to me that the problem isn't with my processor or memory on their own, but rather how they communicate. what should I do to make the system more stable at higher OCs?
