Common issue I think but I keep getting one of my cards (can be either) rev down for 10 mins then when it restarts it returns the above in BM log. I don't wsnt to reset project. Have underclocked core + mem + even have a desktop fan blowing at PC to keep things below (or little over) 80C. AVG avoids folders:+ ident protection off,, did leave a core free but made no dif. Virtually every trick in the book.
