they're all at default right now, MCH is set at 1.250V.
It could be the mem voltage, it's now set at 1.78V and my Plats are rated 1.8V but so far this was not a problem, just that one time. too bad the voltage adjustment still has a quite high granularity of 0.4V, 0.1V would be perfect.
Anyway, I'll find the time to re-install everything from the ground up and see what happens.
My main gripe now is with the ATA/SATA issue, why the drives are labeled as ATA if they are not. Maybe it was when I flashed to the latest 1521 BIOS, the board initially had a very early 1251 BIOS still with lots of issues/bugs. Maybe re-installing will do the trick.
also the Dolby tab doesn't show up in the IDT control panel.
