I'm already learning to hate this board with a quad, just like every other Nvidia chipset board I've been through (EVGA 680i SE, XFX 680i LT, Abit IN9-32X MAX).

Tried Mark's suggested settings and plenty of vcore with my X3220 -- it'll get in to Vista occasionally, but I've yet to get more than a couple of minutes in with Prime95 on 4 cores. It doesn't just stop the threads, it locks hard.

Tried upping a few things, but the northbridge is already running hot from feel and I'll be the first to admit I don't know what half those settings are referring to, so I'm a bit leery of setting them sky high. Mark's default settings don't normally get in to Vista. With a bump, sometimes they do, sometimes they bluescreen before getting a desktop up, other times they black screen.

I've seen plenty of "DRIVER IRQ NOT LESS THAN OR EQUAL" and similar bluescreens, and multiple references to 'ecache.sys' if I'm remembering correctly. Nothing very helpful; just general instability I figure.

It's fine at stock, of course... but I didn't pay this much to run stock. I'm pretty pissed off.
