i'm looking at my bios and the voltage for my memory is running at 1.8v & 5-7-7-24 (or something like that). the memory i bought said 5-5-5-15 @ 2.0v. should i manually adjust the timing on my memory?
Yes, manually change them.
also, my e8400 is reading at 8x for the multiplier. should i up it to 9x and turn off speedstepping?
Yes, run it at 9x with SpeedStep disabled. I prefer to disable SpeedStep (when OCing only) because the $4-5 in savings per year are not worth the possible instability.
i tried to up the voltage of the memory from 1.8 to 2.0v and my computer would hang at the "verifying DMI pool data" or something like that... i'm not sure if upping the voltage is the culprit though.
Try 1.9v. Also keep SPD at 2. What FSB are you running?
