New M/B now unable to OC my 9800pro/xt

Hi All;
I just finshed up on installing my new Abit Nf7-sV2. I kept my 9800pro flashed to XT. It was never a high over clocker, but was very stable. I would use 432/372 with no problem.
Now, When I use the ATI tool, it will barely stay at stock XT speeds. Does anyone have an idea as to where I should begin to look. I have also just installed a modded vesion of the ATI catalyst bios. No change at all.
Thanks in advance
Bill

are you talking about the catalyst drivers? as in the omega drivers? if so that can effect your overclock

Make sure that your agp/pci is locked at 66/33 in bios. If that doesnt work try the ati 5.2 benchmark they worked great on my 9800pro > xt. 5.3 and 5.4 cause problems for me.
