Damn, those EP45T's really seem to play along nicely with quads too Hoss331, and that vcore is astounding! If I knew a little sooner I would have probably gone for one of these and avoided all the hassle I've had with getting a decent set of DDR2. Since mid-november I've been waiting on nearly £200 worth of refunds from a DOA kit and a pair of mislabelled dominator GTs

I backed down to 490x9 last night and CPU was stable with 1.40625 vcore (1.36 in CPU-z), so whatever damage I might have done, it doesn't seem too drastic. Just nudging up to 495x9 now, and I'm getting errors about 12 minutes into small ffts which I think is a good point to properly tune the refs and vtt as I've not been 100% on these.
I've gone about finding stability using my knowledge from the MIIF, which has got me a fair bit of success, but I would like to hear a summary of some of your methods in case I'm missing anything if anyone is willing to oblige?
