I have reached an incredible 905MHz Core, 1810MHz Shader and 4400MHz Memory @1.2V 52C loaded! I have run OC Scanner for several hours with no errors and OCCT has also produced no errors! When I had all of my problems I was using Nvidia Inspector , since I change to MSI's newest version of Afterburner the buzzing/problems disappeared and OC limits exceeded my wildest expectations! EVGA's OC Scanner (79% GPU usage) does not fully stress my card like Furmark does use 99% GPU usage, is GPU usage the same thing as GPU load? There is absolutely NO buzzing anymore, just a quiet heavily OC'ed card!
