rzande1Hi everyone. This is driving me crazy. I have the i9 10900k which has the internal gpu. I am trying to get my system to use my EVGA gpu but for whatever reason it will only show a picture from the DP port on the motherboard. Anyone have any ideas? I am using my old EVGA classified gtx590 which (while it is pci 2.0) be compatible with the pci 3.0 slot. I was waiting for the new Nvidia 3000 series to hit before upgrading. Does anyone have any ideas?
rzande1Thanks so much. That was the issue but of course also uncovered that my GPU has failed too.
rzande1Ok maybe we are talking in circles here. I have one physical gtx590 Evga classified card. It is the single card that I have been using for the past 10 years or so. I don’t have two physical cards. There might be multiple processors within that single card but still just one card.
TiN_EEIt's not much about GPU itself, but rather use of PCIe x16 to dual PCIe x8 bridge that GTX590 has. If that bridge is not initialized correctly then PCIe host will not even see the GPUs behind it. Rather special case here, so direct connected old GPUs still should work fine in modern boards.

TiN_EECorrection, bridge chip on 590 (and previous cards like GTX 295, 7900 GX2, 7950 GX2) is somewhat quirky and problematic Gen2 NV NF200 bridge and not more standard PLX. It's operation was not without issue even with current motherboards of that era. It's bit much to expect designers of modern HW spend time to support 11 year old bridge-connected VGA, to be fair.
