Hello.

I recently upgraded to a Voodoo 3 2000 AGP card, and ever since I've been getting random BSOD errors, all starting with "VMM(01)". My system is an AMD K6-2 500 (not overclocked, but with a BIG GlobalWin heatsink / fan http://www.PCGuide.com/ubb/smile.gif), 128MB RAM, Gigabyte GA-5AA motherboard. I've heard various solutions on the net relating to better cooling and increasing the CPU core voltage slightly, but neither seems to have any effect. When I switch back to my old graphics card (an S3 ViRGE PCI), everything's fine. Could it involve the AGP slot? I'm using the latest BIOS and drivers.

Thanks

I read this fourm entry (which could very well be the same one you read) http://forums.32bit.com/showthread.php?threadid=2536&pagenumber=1
There seemed to be varying opinions. To continue with the cooling issue, check to ensure air flow in the system in not inhibited, even with a nice HSF combo if the flow is blocked, well you know...
Another idea popping into mind, based upon the pci card working and the agp not, is there is a timing issue. Have you incorporated the VIA patch for AMD processors over 350MHz (also known as the USB fix)? If not, research it here http://www.usbman.com/Guides/VIA%20Tips%20and%20Tricks.htm and download if applicable to your system. Let us know how things work out. Also, which Operating System are you using?

One of these days I'm gonna cut you into little pieces...

Thanks for the info. I'm using Win98 SE, but the GA-5AA is based on the Aladdin V chipset so the VIA stuff doesn't apply. I noticed that the Voodoo is putting out *serious* amounts of heat for some reason, so I'll try attaching a fan to the CPU and see if that makes any difference. I read someone's comments on the justification of the CPU core voltage increase - they said that if the PSU isn't up to scratch the larger voltage the AGP takes up affects the system CPU; how true that is I don't know... Maybe it's just time for a new PC! http://www.PCGuide.com/ubb/smile.gif

I've just found the following website relating to incorrectly installed VxDs. It looks quite interesting and may be of assistance to anyone else having similar problems:

I've yet to try this myself - I'm going back to university tomorrow, so my PC's all packed up. I'll let you know if it works.
