I have rebuilt on of my home computers recently and have not been successful at getting GPU grid work to complete since. I get the above captioned error code. I have rebooted my PC, reloaded 180.48 driver and upgraded to BOINC 6.4.5 earlier tonight without success.

All thoughts and comments welcome. I am running XP Pro SP3 32bit, Q9950, EVGA 790i Ultra mobo and 2xGTX260 Core 216 (not overclocked) and not running in SLI mode.

By the way, I found nonthing about 6.53 application. What's new in this version?

Good morning all,
I wanted to post a final message to this thread to advise I have managed (some how) to get GPUGRID working again on one of my home computers. I tried a number of things including downgrading to BOINC client 6.4.2, and I also downgraded and installed NVIDIA driver version 178.28. After a number of reboots and who knows what else, it started working again about 36 hours ago.

It seems that GPU computing is definitely in its infancy and needs to mature a bit before it will be ready for the general masses. I am glad to help in this growth process.

GDF, thank you for your suggestion. I am back crunching again!

Neil
