This GTX 260 has done F@H for 2 months using 185.85 drivers with no errors. Any other drivers error rate is 20-30%. Have run Fur and CUDAmemtest several times with no errors. All errors seem to be same as above.

Thanks!

Update:

Have installed 182.50 drivers and took OC off CPU. GPU is and was at stock clocks. So far it is 1 hour into a WU which is almost twice as any of the others so maybe........

Another update.

Installed Vista 64, Nvidia driver 186.18 and Boinc 6.6.36. First WU errored. If second one does will try 185.50.

Running out of ideas here......

I'd suggest 182.50 drivers. An oldie but a goodie. We've had various issues with 185.xx and 186.xx drivers on GPUgrid. Remember you have to uninstall the old drivers before reinstalling. Also finish off any cuda work (regardless of project) and make sure you report it before doing the driver reinstall.
