Problem with running GPU tasks

While SNAFU still reigns supreme I overcame the GPU stoppage. I noticed in Windows system tray that GPU computing was "disabled at user request". Wrong. Actually I'd set BOINC to 'use GPU while computer is in use' but that factoid was ignored.

Bull in the china shop, I deleted BOINC directories and started all over again. Presto! GPU computing is working. My regrets to all the inconvenienced wingmen. I plan to stick with 6.12.34(64) for a while. This all started when I installed BOINC 7.0.25(x64) and Nvidia 301.42.

----------------------------------------------------

Situation normal in the SNAFU sense. I just upgraded to Nvidia 301.42 and Boinc 7.0.25(x64). Suddenly my GPU is at idle, no GPU work although I have downloaded GPU work in my queue from Collatz and Primegrid. Its not running.

GPU Caps Viewer says the GPU core is idling along at 50MHz, load near zero. Here's a copy of Boinc startup event log. Any experts see a clue here?

PS - thinking "corruption" I reinstalled Nvidia, no improvement.

Thanks Art

Try installing Boinc 7.0.28 instead, 7.0.25 had a number of Bugs since fixed,

Startup messages don't tell you much about running tasks. You would need to set a number of debug flags in cc_config.xml.
you want cpu_sched_debug and coproc_debug. you also want to attach the files global_prefs.xml and global_prefs_override.xml here.

What could have happened is that you looked at the local preferences and instead of 'cancel' clikced 'ok' thereby enableing [default] local preferences. These override the ones supplied via the web.
Depending on boinc version it can grab some of the settings from the actual web setting, making no difference at start, but making it impossible to change anything later via the web settings.
Deleting the boinc dirs would have deleted the local preferences files, thereby intruction boinc to use the web settings again.

NB if you edit a post at a later time because you want to add something it REALLY helps if you mark the new portions with 'edit'.

I take it the upper part of your post is the later edit, meaning it is working now.

You should still skip boinc 7.0.25 and update straight to boinc 7.0.28 if you want to update.

Thanks for the tip. Reading between the lines, 28 is more stable than 25. Although Boinc says its "for testing only". After deleting the directories and starting over its all working now with V6.2.34(x64).

Am I missing anything vital by sticking with it?
Thanks
