Don't know if you commented on my post, but thanks in any case. I will try to up the vcore and see what happens. And I'll up the VTT a bit more maybe 1.4 or maybe a bit higher and see if it will help.

I still need to put the QX9650 in and see if I can get 450FSB stable.
VoodooProphetII, I wasn't commenting on your post sorry. Just sharing some observations. If it helps though

I wouldn't think you need 1.4 VTT for 450FSB. 1.35 should be enough. In fact nearer the beginning of this thread Eternal Fantasy posted settings for a Quad at 450fsb.

Is that power supply of your's going to be up to the job? A GTX280 and QX9650?
