I'm not sure what has gone wrong, but my Windows 7 work station has quit receiving GPU work units. All of my preferences seem to be correct. What can I do to get this corrected? Suggestions?

I suggest you start by unhiding your computers and posting the first 30 lines of the BOINC event log so we can see what is happening (or not happening).

I'm having the same problem with my GeForce 9800 GTX+ card. The GPU is recognized by BOINC but your servers never send any GPU work units to my system. As per your instructions I've included the startup lines from the BOINC event log...

This problem has persisted for at least 2 months...

When checking the project preferences, have you checked that it says "Use Nvidia GPU"? If not, enjoy your preference accordingly. Make sure they are for the correct venue/location that your computer is set for: home.

I would bet it is the block that SETI put in place against the 34x.xx drivers on older (Pre-Fermi) GPU's.

I would recommend going back to 337.88 and seeing if that allows work.

Stupid phone. I meant "change" not "enjoy". Teaches me to not triple check what I swiped.

---

I verified that "Use NVIDIA GPU" is checked in my preference section. I just downloaded and installed the older NVIDIA driver package. I'll post a follow-up message with the results...

Thanks for you comments. I wonder why the SETI folks blocked the newest NVIDIA driver release...

It's because Nvidia dropped support for older (pre-Fermi) videocards from those drivers. See @Pre-FERMI nVidia GPU users: Important warning for a lot more information.

---

The older drivers brought the CUDA work units flowing back into my PC. Thanks for the advice! I guess it is time to read through the "@Pre-FERMI nVidia GPU users: Important warning" notes...

Best Regards,
