It could be third party controllers...sounds like it.
Trixx, Afterburner, Asus installed?
It's a brand that I've never heard of called PC Partner. Cant see any drivers on their website. In saying that though, I never looked on sapphires website for the Drivers. I did a quick google and found them on their website. I will give this a shot and see what happens.
Update: Installing Sapphire drivers didn't help. The only difference it made was in MSI Afterburner, the memory clock and clock speeds have defaulted to the minimum, and I can't raise them.
