I know that seems to be totally oposite to what would work.. but with those settings I have had no problem booting over 1200. I was playing around with mine tonight and would not boot when i chaged from mod to light (wtf) back to mod and booting again... (still failing stress, but i may be just trying to push it too hard).

My only other differnce was more volts, but we have differnt ram and yours may melt at my 2.3v

Thanks mate but no go. I tried those combos before, and just did again then for the hell of it, and no go.

I just updated to bios 1201 and made no difference. I was hoping it would. I'll just keep playing with it.

Have you tried using a higher VTT?

No, It's not my cpu holding me back. I can be stable at 571 FSB with those vcore/vPLL/vVTT settings. It's either my ram, or the MCH, or bios, that is my issue. However as this has been my situation from bios 0610 to 1201, I think I can rule out bios. It must be ram or MCH.

In bios 1201 the ram voltages for me have changed. Now:

Bios/ Real Idle/ Real Load
1.96v /1.97v / 1.98v
1.98v /1.99v / 2.00v

Now I basically get what I set, and it increases by 0.01v under load. That is much better.
