Video Card Speed Change?
It has seemed to me that my computer had been operating slower and
slower. I confirmed this by checking the reported CPU speed and doing bench marking with various utilities. The PC has a 550Mhz CPU and was originally bench marked at 233Mhz (doesn't sound like much but it makes a HUGE difference). I finally (by accident traced the problem to a new NVIDA GeForce PCI video card. The card had to be removed to get the mother board out and because I was changing jumper settings to get the speed corrected to 550 Mhz, I simply left it out while testing. When I finally got the machine running properly, the only thing left to do was button up the case and reinstall the video card. As soon as I put the card in, the speed dropped to 333 Mhz. Through trial and error I have determined that with the card out the machine runs at 550 Mhz. With the card in the machine runs at 233 Mhz sometimes and 333 Mhz sometimes. What is causing this and can it be corrected? |

What speed is your nVidia card? AGP 2x, 4x, or 8x?
Check in the bios settings for the AGP speed, and see that it matches your card. Note also that some video cards are incompatible with some motherboards, voltage wise. See the article here http://www.devhardware.com/c/a/Video...ware-Part-3/5/ Good Luck BarryG "saeengineer" wrote: It has seemed to me that my computer had been operating slower and slower.

Note also that some video cards are incompatible with some motherboards,= =20 voltage wise. See the article here http://www.devhardware.com/c/a/Video...ware-Part-3/5/ Don't know the speed of the card. It wasn't in the documentation. It is a PCI card not an AGP. Thanks for the article. I replaced a previous NVIDIA TNT 32 M card with the new GeForce 64 M. I didn't have any speed issues with the TNT. |

I'm only stabbing the dark, but you may be using a PCI 2.3 card in a PCI 2.2 slot or some such thing. See this article http://www.pcisig.com/specifications...tional_pci_23/ Good luck BarryG |
