With gminer 2.04 to 2.06, was only seeing frequent miner program restarts on c32, now with v2.08 certain rigs see illegal memory errors, and the restarts may have gotten worse. Highest shares accepted over the past day has been 370 shares before a restart. Solution has been to revert those memory error rigs to c31. I've tried +0 memory, -300, -502, & that didn't solve. Solution was to isolate the problem card and point it to c31. Even better is reverting to a previous version of gminer, 2.06 or prior for c32 stability. Also, gps of 2080 Ti has decreased slightly with 2.08. 1070 Ti received 15.4% bump from .26 to .3 gps, 1080 Ti is 13% bump from .46 to .52.
