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 |

Any ideas? Thanks to all who read or reply, Rene Lamontagne The new card probably uses more power than the 9800 did (you didn't mention which version of the 6600 you have) and the power supply you have can't output enough current for both the video card and overclocking the CPU. You probably need a higher wattage PSU if you want to OC the CPU. ----------------- www.Newsgroup-Binaries.com - *Completion*Retention*Speed* Access your favorite newsgroups from home or on the road ----------------- |

Any ideas? Thanks to all who read or reply, Rene Lamontagne Have you tried setting the AGP/PCI frequency to 66/33? Bill -- GMail, Google Goobers and Web to Usenet gateway users. This century's answers to AOL and WebTV. 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 |

The video card is a BFG 6600 OC which is factory overclocked. _____ I don't think you should give up on your current equipment. Since the PCI and AGP bus speeds are locked to the standard 33/66 MHz, and your power supply is completely adequate (500 Watts should handle several LARGE hard drives, enough peripheral cards to fill all the slots, more memory than you can install, multiple removable media drives plus any AGP display adapter that will fit; remeber, 500 Watt power supplies were rare in the Pentium 4 era) then it is time to look at some other change that may have affected your ability to overclock. The 'gigabyte 8P2667 ultra' designation does not show up as a motherboard on the Gigabyte site, so I can't look up particulars for you motherboard. ** My first suggestion is that you check to see if you may have made a change in the motherboard BIOS that cause a reboot when the FSB is not set to the correct speed. This is a setting sometimes available in Pentium 4 era motherboards. ** Second suggestion, make sure that all connectors are properly mated and that all the connectors are still good (no pins or sleeves in the Molex connectors have slipped out to the point that good contact is no longer made - it happens, ask me how I know B^) ** Third suggestion is that you try reducing the overclock amount to 0 MHz; check for proper operation, then gradually increase the overclock amount until you find you need a higher than standard CPU core voltage (just like beginning the overclock all over again.) I can not offer any more specific suggestions without a manual for your particular motherboard, and that I can't download without a correct identifier. If you can find another motherboard identifier and post that, then perhaps you can get additional help. I still have a working aBit Pentium 4 system that I first overclocked with a Pentium 4 1.6a GHz to 2.4 GHz, and later to 3.3 GHz with a Pentium 4 2.7 GHz. The power supply used was cheap and rated at 300 Watts. It's retired now (I made a mistake in choosing RamBUS memory when it was cheaper than alternatives, and installing only 640 MBytes - and then RamBUS got too expensive to consider adding more.)

Phil Weldon Sorry about the model of MB, it is a Gigabyte GA-8PE667 ultra, When fsb is set to 166 which is default its OK but enen 1 MZ over, say 167 it resets to 166 on bootup, no other changes to the bios . Installing the ATi 9800 or X1950 lets it OC to 2.8 to 3 GHZ. So it is definatly the Nvidia 6600OC card which prevents it, Luckily I found Another Saphire X1950 video card this a.m. and everything is runnig happy at 2.9 MHZ again. Thanks for all the help and suggestions. Regards, Rene |
