I'm at a loss to explain it. It's rock stable in everything, but crashes out of 3D apps at 4.3GHz+. I have tried 2 different video cards and its the same. The cards are fine they work perfectly at lower cpu clocks.

I had to set the NB GTL Ref to -70mv or it would crash out in 3D at 4.0GHz, but now with that set up, it does 4.23GHz fine. Dropping to 1:1 ram at a little over 900MHz does nothing, changing NB GTL Ref just makes it worse, changing vNB makes no difference, changing PCI-E freq does nothing, changing clock skews/ram skews seems to help a little but only delays the inevitable. I even changed PSU, and flashed to the latest BIOS, but the same thing happens. I know this board well and I cannot 'adjust out' this issue.

I Never Can OC On My M2F In High FSB
Can I Go For Change Board To DFI P45 For Best OC??? DFI Is The Better Than M2F For Get High FSB Over 500.....?
Is That Think Better Or Stay With M2F Then In Future Go For Corei7 Or Phenom 2
Tanx For Sugestion
Sorry For My Bad English
To get over 500FSB on a 9550 you will need to give it a lot of vcore. Depends on the stepping, if its an E0 it will do it more easily but regardless its not going to do it at a 'normal' vcore, and it's almost certain it will not be anywhere near stable. DFI P45's are not very good overclocking quads from what I've read but give one a go if you think its your board.

Well at least finally you got a decent board. Such a shame Asus dropped the ball on the QC on these mobos, but as a result in the meantime you found a way better mobo for less money, so that's something. Good luck with the sale.
