Default Strange hardware problem -- overheating

Hello! My Quadro FX 1000 worked fine for a year or so in an older PentiumII Xeon box. I then moved it into my newly built Opteron system, where it worked fine for a month.

Now it still works in text mode (huh!), but when I try to bring up X, the system usually locks up emitting only a steady loud beep.

At best, only the display seems locked up, but I can get in from another system and see the Xorg process taking up 100% of the CPU.

Although the little fan, that is mounted on the card's heatsink is spinning, the entire card is very hot to touch and I need to wait for it to cool down. The rest of the system seems cool and works fine...

What could be wrong? Thanks!

Check mobo voltages and/or AGP drive strength.

Thanks a lot for the prompt response!

After pulling the card out and using a PCI one I can go into BIOS to take a look.

There is a setting for "PCI Latency Timer" -- currently at 96. Should it be higher or lower?

There is also "AGP Aperture Size", currently at 128MB (I remember raising it from 64) -- is that what you refer to as "AGP drive strength"? How does this value affect the card's temperature? There is also "FW Enable" switch, which I set to "Enabled" without knowing, what it is. Can you comment?

What else should I be looking for?

Go through your logs (/var/log/) and target the most recent ones when it locks up.

Just a thought: check your ram with memtest86. This problem is one for new systems but do a check anyway.

If I remember correctly the Quadro FX1000 is based on a GeforceFX 5800/5900 chip. These boards use an external molex connector to get more power. Make sure you give the FX1000 its own powerlines from the powersupply and that you don't share the same powerline with other devices. Further make sure that your powersupply is powerfull enough. I would check these things first.
