I have been noticing that my 780Ti's are not producing the same amount of PPD for folding. As I was researching why, I noticed that when I did a GPUID, the PCI lanes it has for each card do not match what my mother board says they should. I checked my BIOS and they are all set for Gen3. I have an ASUS Rampage Black IV Black Edition board with an 4960X for my CPU. The GPUID I got yesterday it stated that the first slot was PCI x4 3.0, the second was PCI x8 3.0 and the third one was PCI x16 3.0. Not sure why the first one is x4 when it should be x16. I can pull some data when I get home latyer today, but I cannot figure why this is happening. Any ideas?
