Folding for 4 years but I still have questions. How do I add a GPU folding slot in FAHControl? I did try to install the second GPU and re-start and tried to "Add" in the Slots tab but the pop-up doesn't accept any input. I did have some problems with that GPU but it does pass Combuster in its OC state. Edit: I tried to install the second card in another rig and after 2 minute off folding it BSOD my rig in stock settings. Bad, bad GPU. RMA'ed. Any folding results from the new 290X?
