almulder Posted December 2, 2021 Share Posted December 2, 2021 So I have discovered "lspci -vv" today and notice that I have a few things that show they are downgraded. Is this normal? If not any idea how to fix it, as I have a few devices that are like this, but all others are fine. Including my RTX2080 (also at 2.5) I have an AMD x3970 in a gigabyte TRX40 Aorus Master with a GTX 1050ti, RTX 2080, LSI SAS9207-8e in the PCI slots, and all 3 nvme slots used, and only the first 3 sata onboard connections are used. (I should have plenty of PCI lanes so I dont think that is the issue) Example: 21:00.0 VGA compatible controller: NVIDIA Corporation GP107 [GeForce GTX 1050 Ti] (rev a1) (prog-if 00 [VGA controller]) Subsystem: eVga.com.

Bios is up to date, and pcie link speeds are set to Slot 1 - x16 Slot 2 - x8 Slot 3 - x16 Slot 4 - x8 GTX1050ti = slot 1 SLI card = slot 2 RTX2080 = slot 3 but they still show downgraded, and from others that I have seen run this also show downgraded for stuff. Thoughts? Quote Link to comment
