Official MSI P7N Diamond (780i) Discussion/Review/Overclock/Guide/BIOS Thread

[silent-circuit]

Hi Silent,

Standard questions apply here:

what bios are you using?
what are you trying to OC to?
what are you setting for vCore and vDimm?
how far have you pushed other settings?
Lastly, what is the VID of your X3220?

Just for s and giggles, try a GTL REF between 30-35 instead of 65-67 and see if that improves things any.

Bios is 1.1 B4, taken from the MSI forums. I haven't tried the Performance BIOS as this one was apparently better for quads in most cases.

I'm trying to hit 3.6Ghz (400Mhz FSB x9) stable with the X3220 and move up from there.

vcore is +0.2 (probably more than it needs) and vdimm is 2.1v which is suggested by Patriot (at 5-5-5-22 2T, not pushing the sticks at all, just trying to get stable first)

I just bumped things a notch or two above your recommended. It's very hit and miss, mostly miss right now. So far this isn't doing any better than the 680i LT did, and it cost a hell of a lot more, so I was expecting /some/ improvement.

I don't believe this board is reading my VID properly; the IN9-32X MAX and the 680i LT said it was 1.18, this one seems to think it's 1.24.

Cooling is a Black Ice Pro II with a pair of Panaflo low speeds at ~8 volts on a rheobus and a Swiftech Apogee GT with AS5. I've cranked the fans and had no better results. Temps are higher on this board, presumably due to its setting the vcore higher, but they don't top ~45C load at stock and I haven't seen higher than high 50s C when I've managed to get it to do anything at 3.6Ghz.
