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.

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.

There have been several PCI versions in the past also. 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.
