Yesterday I rebuilt one of my open air dual GTX 970 machines into a 4U rack case. Unfortunately I lost the BIOS profile due to a dead motherboard battery, but I remembered most if not all of the overclock settings and had it back up and running again in no time. I left it on a bench in the comms room folding overnight and came back 24 hours later to check on it and install it into a cabinet, but instead of the ~600k PPD it normally produces, it's now churning out a mere ~120K PPD. Both cards are folding on FahCore_21, one is on 48k PPD and the other at 65k PPD. Does anyone know what might be going on here? This has crippled my efforts and I would like to get it running properly again. I had attempted to install a third card in the machine, but I didn't have enough PSU cables for my old 1250W Enermax to spread the load across the rails and it refused to boot with all three installed, so I pulled one and put it back into another board for now until I get some connectors from Hong Kong and make up some more PCIE cables.
