I have been trying to get a P2200 working in one of the x8 slots on the X10DRH-CT motherboard. The fan is spinning, and the PCIe link is detected in the BIOS, but once booted lspci doesn't list the device, and dmidecode says the slot is not in use. I tried a Quadro 600 that is exhibiting the same problem, and an AMD R9 Nano, which is working as expected.
The working AMD card is externally powered, and I am now wondering if the issue is that the x8 slot is not supplying enough power for the P2200 or 600. I know the PCIe spec calls for only 25W on anything < x16, but I have never encountered a motherboard where this is actually a problem.
Am I SOL with this, or is there anything I can try to get this working on the X10DRH-CT? Any way I can confirm that bus power is indeed the issue here? It could be a red herring.
Thank you!
