I have two 8800GT's folding in SLI mode. For some reason GPU2 finishes (sometimes) but doesnt automatically download the next work unit. I have to exit and restart?
The next unit should be downloaded and started automatically. Is your network connection properly always on? Which GPU drivers are you using?
It might be getting blocked by a firewall, have you created an exception in windows firewall for the FaH client? (Win firewall is a PITA as you all know)
Certainly worth trying. Drivers above 190 are supposed to allow folding with SLI in place, but who knows what might be different
