Message 19840 - Posted: 9 Sep 2014, 9:04:15 UTC

I have an amd 7770 and an r7 265. Both cards use only 80% of their capacity with Collatz large and solo. Is there some setting I can use in app_config to raise these percentages a bit higher? I am using boinc 7.0.64 and need to continue with that version.

Are you leaving a cpu core free for each gpu to keep it fed and running at full speed?

Then Slicker's answer in this thread is the problem, in message #19835.
