Running windows vista, just upgraded to boinc 7.0.25
I am receiving computation errors on Collatz 3.11 nvidia GPU. There are no indications of errors in the event log. Anyone else having computation errors? I had been running verson 6.10.56 for a long time with no problems. What would you recommend? I searched the forum and did not see anything recent about comp errors llike I am experiencing.

Looking at your host, I'd say update your drivers to something more recent, 197.16 was the 1st driver to support OpenCL, probably way too old, and one of your failed Wu's:

- exit code -11 (0xfffffff5)

Or wait for Slicker to restrict the OpenCL app to newer drivers.

I re-enabled the CUDA apps as well as added a new CUDA 4.2 app. nVidia driver 301.42 or later is required for it, so if you are going to update your driver, you might as well grab the latest one so it will handle both OpenCL and the CUDA 4.2 application which is quite a bit faster than the OpenCL version.
