I don't know how u guys are getting any overclocks at all?

I'm running an EVGA 7900GT and no matter what I set in nibitor it boots to 450mhz 20% fan speed at 1.2v.

Nvflash mybios.rom -5 -6 [ENTER] it flashes as usual successful but it stays at 20% fan and 450mhz...

Is it a Windows 7 ultimate x64 issue?

I'm getting better fps on a dual xeon x86 rig with 1gb ram and a 7300GT agp at 600Mhz in Windows 7 Ultimate x86....

What's up with this...
