P4, overclocking with Nvidea Gpu

 

Since installing an Nvidia BFG 6600 video card I can no longer OC my 2.4
P4/533 CPU.
It used toOC to 3.0 Ghz and run stable, Now it will not OC at all I canset
the fsb in bios but when I rebbot it goes back to defaults, MB is a gigabyte
8P2667 ultra. it OCs fine with my ATI 9800 older Video card.


Any ideas?

Thanks to all who read or reply, Rene Lamontagne

 Have you tried  setting the AGP/PCI frequency to 66/33?

Yes , AGP/PCI are locked at 66/33,

The PSU is an Enermax EG465P with 20 amps on the 12 volt rail, 44 amps on
the 5 volt and 38 amps on the 3.3volt rail,

I have tried a 500 watt Antec with same results.

The video card is a BFG 6600 OC which is factory overclocked.

Thanks, Rene

 


 If you put the ATI back in can you overclock then?

 Those P/Ss should be enough unless you've got a lot of other
hardware in there. If you do, try disconnecting most of it just to
see if it will post when OC'd with the BFG card in place.

Yes, putting the ATI 9800 back in lets me overclock as usual.

Also, I borrowed the X1950 ati card from my Sons system last night and it
also worked fine , was able to OC the 2.4 to 2.9 or so , BTW Nvidias
response to this was Don't Overclock !

I guess I may just have to go to a newer ATI card but don;t want to spend
too much as this AGP system is getting pretty outdated.

Thanks, Rene
