Is the bench/game hard locking when this happens? I never got vertical bars like that with my card.
If I pushed the memory too far I would get a pure black screen and a hard lock or a crash; not always a BSOD though.
Pushing the core too far I would get artifacting and flickering which was typically solved by more voltage. Even when I ran out of voltage to add, a benchmark would complete no matter how severe the artifacting got...I let it go one time through a whole bench expecting it to crash because of how awful the the artifacting/flickering was, but it finished the bench. My score was lower than previous runs but it held through, I was
What are your temperatures on VRMs and the core like at those clocks? If your rig pics are up to date it looks like you're
What drivers you running? Did you scrub drivers before re-installing each time?
I would reduce the memory clock back to stock and see if that 1175 core is stable with +100 mV; 100mV seems a little high for only 1175 unless you got an underwhelming card.
What utility are you using to OC? Whichever you use. make sure ULPS is disabled and you are forcing constant voltage. A few people have had issues with AB, myself included. Trixx has solved some strange issues for a few people, you may want to consider trying it.
