Title: x99p-SLI not detecting second GPU - "base system device" in device manager
Post by: romandesign on April 14, 2016, 09:47:21 pm

There is a broken device in Device Manager - shows up as "base system device", and in properties has "PCI slot 2 (PCI bus 4, device 0, function -). When I install second GPU in slot 2 - it's not detected at all. However in slot 3 it is detected and working, but the "base system device" is still showing. How do I fix that?

I would rather put the second card in slot 2, it has more lanes and there will be more room for air to cool the main GPU.

Look in Miscellaneous Settings and under PCIe Slot Configuration maybe you can change something in there.

Plus have you done this too:

When two or more graphics cards are installed, we recommend that you connect the SATA power cable from the power supply to the ATX4P connector to ensure system stability.
