Over the weekend I followed the GPU2 guide for folding on multiple on graphics cards. I disabled crossfire and then made a dummy plug for my second card. Once done with the dummy plug I connected it and configured [email protected] so that I run a separate client on each GPU. Now I get a "write protect" error when opening GPU-Z to monitor my cards' temps and also when launching the [email protected] client on the 2nd GPU. I am also noticing issues with clock switching on the second card and not quite sure what is causing all of this.
