maybe i found most idiotic fix for crashing, i downgrade my GPU drivers to 576.02, REMOVE ram cleaner, Turn back on OC profiles on GPU an MB software!
you asking "and where idiotic part?"
IT'S STARTS HERE: when i turn up a Server i WAIT for it to say: "Server is Load Good Game", than wait for MOAR preset and other mod to shop up in consel, AND ONLY AFTER THAT i turn on Launcher, i played two almost houred raid! EACH!, no crashing...
i dont know how the hell it's works, guys
