Is there a way to use a PCIE 4 nvme in a PCIE 3 PC and use the right/read speeds of the PCIE 4? Happy to use an external adapter or anything. I've heard it caps it to PCIE 3 speeds of 3000ish so trying to work around this without replacing motherboard.

If your pc doesnt support PCIe gen 4 there is no way to run it at gen 4 speed, expansion card or not.

But PCIe is bacward and forward compatible, so you can use a gen 4 m.2 on gen 3 PCIe, just with gen 3 speeds

If you want me to answer, please use the quote function or tag me. I dont get notified unless you do

PCIe Gen 3 will not impact the performance of a 980 PRO.
