gpu GPU PCIe lane didn't run at x16 3.0 as it should, instead run at x4.

[curxe]

I just find out that my gpu didnt run at x16 (Gen 3, coz I know I got Gen 4 PCIe gpu) while browsing stuff in bios. I was scouring the net for some information but because theres always something that I miss. If possible, I want to get it work but if i cant do so, I appreciate new knowledge from this thread. I also provides some details of my pc here.

p/s: Navigating the msi bios is confusing af. That one of the reason I asking this here coz it might be in the bios setting itself.

which slot have u put it in? also how many m.2 ssds do u have

Put it under load - it'll probably start showing 16x in GPU-Z.

have you tried clicking on that question mark next to the PCIe x16 4.0 textbox?

You didn't answer the slot question.

if you plugged it in the bottom port then it's gonna be running at x4 speeds.

This is the mobo that I used and the gpu was using the PCIe with that metal housing

Thanks to everyone that trying to help me with this case, I able to get x16 to work.


I had to clean the PCIe lane with Isopropyl and reseating the gpu. Didnt know which one of em help me fix the problem tho.
