I have a Dell T7610 and I got 2x P40s for running LLMs. However, nno matter what I do, I can’t get both of my P40s to work on the system. Both of them work by themselves in either PCIE slot, but when both of them are plugged in, the one on the first PCIE slot always returns an error in device manager. Does anyone have any experience with setting up these cards in a system like this?
