PCIe 3 Riser cable

[jchakramakal]

I have a B550 mobo with PCIe 4 x16 slot and recently purchased a RTX 3070. Once I get it I need to change gpu in my system from RX580.

The riser cable i'm using currently in my itx case is a PCIe 3. I know I need to get a PCIe4 riser cable.

 

But will the PCIe 3 riser cable work until I get the new one?

The riser cable can probably do PCIe 4.0, if not you can set the slot to 3.0 in the BIOS. You won't see a performance loss, though.

Yeah, people have benched RTX3090s on both PCIe 3.0 & PCIe 4.0, there is absolutely no difference in performance between the two.

Ya, that's helpful. I'll try that.

Its a custom build case. Attached some pics. You can see, its height adjustable and in the inside I can adjust the plate were mobo is installed based on GPU thickness/CPU cooler height.
