Just tried that... No go.
I tried installing the 11.7 drivers and see what happened. Good news! Now when I start the miner the temperature shoots from 40c to 80c in literally 4 seconds. I clicked stop there... I'm afraid to let it go. Temps were confirmed in CCC/GPU-Z and MSI Afterburner?! The fan goes from quiet to 100% in that time frame as well.
I'm so confused... Im burning the whole thing down and starting from scratch with a fresh Win 7 install.
