Over the summer I bought a new PC, including the Dirt 3 version of Sapphire's HD 6950. It worked out fairly well, especially after a shader unlock, but I was never able to push it quite where I was comfortable with. Sapphire's Trixx utility seemed to produce poor overclocks for whatever reason, so I decided to use MSI Afterburner.
However, after a certain point, GPU-Z, which I was using to monitor things, refused to report voltage. And MSI Afterburner refused to allow me to see or change voltage. I could still change voltage in Trixx, but without monitoring tools I had little method of correction, and as stated it seemed unstable anyway. This might be related to a driver issue, as I believe it coincided with a Catalyst update...but I don't know for sure.
I have tried a few basic troubleshooting methods. I reflashed to the stock BIOS. I performed a clean install of Catalyst. I made extra sure that it really was the stock BIOS I flashed. Unfortunately, nothing doing. I haven't tried reseating the card, updating the motherboard BIOS, or switching to the secondary video BIOS yet, however.
I'm hoping it is an issue that can be solved with a registry edit or something I've overlooked! I'd hate to have to try to send the card back to Sapphire; I don't think they'd take it back.
