GTX 970 System - Low PPD After Rebuild

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.

Cards are not being utilised properly at all, the GPU usage as reported by MSI Afterburner is hovering around the 60-70% mark, whereas my other system's identical GPUs are between 80-90% and sometimes higher. Uninstalling and re-installing display drivers now.

Copied from the FoldingForum.org topic on the problem, in case anyone was wondering what solved the issue.

Temps were not that bad; I was a little disappointed with the cooling performance of the 4u case but it needed to go in a rack, I can modify it to improve upon that and hopefully keep the fan noise levels at an acceptable level. I am having to run the card fans at about 75% duty cycle to keep the GPU temps between 65-70 degrees Celsius, but the Twin Frozr V coolers on these cards are very quiet, even at 100% they're almost inaudible over the 8x chassis fans which are my real noise concern - something I plan on managing with a GRID+ fan controller.

Anyway, after hours of pulling my hair out I solved this issue very late last night/early this morning. I remembered that when my old EVGA X58 Classified 3 based gaming system at home was running one of these 970s, it had a similar problem with extremely low GPU performance right after a CPU upgrade. I'd borrowed the i7 980X from it to test another board, and replaced it with an i7 930. When I swapped the 980X back into the board again I was experiencing almost unplayable frame rates in games like BF3 and GTAV, which the GTX 970 was previously not having any trouble with. After hours of troubleshooting that issue, the solution was another complete BIOS reset, which solved the problem.

The same thing happened last night with the dedicated folding machine. I loaded defaults, set the CPU overclock values from memory, booted into Windows and the system immediately began utilizing 95% of both GPUs. Something in EVGA's X58 BIOS restricts the performance of the PCIE lanes on the board. I went through every BIOS menu several times with a fine toothed comb and couldn't find anything even remotely related to PCIE performance or anything else that would bottleneck a GPU. All I know is that as soon as I remembered my saga with the low FPS on my gaming rig, I was almost certain this was the same thing. It's quite a common problem too, if you Google "GTX 970 low FPS" or "GTX 970 low GPU usage" you'll see plenty of other people having the same issues in games. Something that gets changed on the board during a CMOS reset/update bottlenecks the PCIE lanes and the only solution I have found with my X58 Classified boards is to load the defaults and go from there.

Note sure, as the architecture is different in this case (one being Kepler and the other Maxwell).
One way to find out ... give it a go

Cheers Doc , it's the misses pc atm and I could use that for folding from time to time.Just don't want to add a card that may slow down this system ..Only just assembled it a few days ago and there is no overclock on it yet !
