View Full Version : 8x AGP card, 8x capable slot, runs at 4x!?

I have a 256mb GeForce FX 5200 AGP card (8x capable) plugged into the AGP slot of my FIC AU31 mobo, which is supposedly capable of running AGP at 8x. When I run Everest, the entry for my AGP bus shows 8x @ 4x. A warning note tells me that my AGP is running below optimum speed, that it may cause performance penalties.

I finally managed to upgrade the BIOS (neither FIC nor E-machines provided an upgrade, for those of you who aren't familiar with the excellence of the AU31), and I have AGP speed set to 8x there. I've got my aperture open to 64, if that makes a difference. Fast write is enabled. I've got 1 gig of memory installed.

Even after upgrading the BIOS, no dice. I uninstalled and reinstalled the card's drivers, using the most recent available, no good. I made sure all my hardware drivers and Win XP updates were in order. I have all of the Nvidia console settings cranked to max, though I can find no way to specify the AGP speed as 4x or 8x anywhere in the Nvidia software or in XP.

I notice in Everest's system resources breakdown that all of the (obviously) AGP-related resources seem to be listed as Shared or Undefined. My PC knowledge ends where these details begin - I know nothing about memory addressing or whatever these details are exactly, but could the lack of dedicated resources mean anything in this case? It's just a shot in the dark at this point.

Ideas anyone? Could Everest just be wrong? Any help would be much appreciated!

The only troubleshooting step I could recommend would be to try another AGP card that you know is 8x capable and see if it works. this sounds like either everest is wrong OR you have yourself a defective card.
My other advice would be to get rid of that paperweight and get yourself a more up-to-date computer, if it's in your budget.
