ASUS P5Q-E (P45) pre-view

There is vtt and there is pll, i am guessing you quoted vtt (FSB termination), cause PLL starts at 1.50v.

I am actually amazed you can do 4.25GHz with 1.12 vtt, but that might be because of auto strap setting you are using (which could be defaulting to 400MHz).

Did you make sure the board is stable at 430MHz FSB and those settings? Drop your multi and test it at 430x8 or less and see if you dont get errors. If you do, then you might want to up vtt or vNB until it is stable. It will be hard to figure out what to do next without this step.

Also, try with your CPU GTL 2 at auto instead of 0.670.

Thank you. I'll try your suggestions.

Yes, the 1.12 for PLL was an error, it's 1.52.

I will raise VTT from 1.12 a little. The Auto strap is defaulting to 333, btw.
