GPU not using PCIe 4.0 x16 8 (SOLVED)
Hi everyone, I recently changed my GPU and MOBO

GPU: RX 6600xt and MOBO: H510M-A PRO which states PCI 4.0 x16 support but the readings in GPU-Z says my GPU is on PCIe 8.0 x 4.0 instead of x16

No NVME connected to MOBO, in BIOS i've only touched Resizable Bar (enabled)

Updated BIOS for MOBO nothing else so far.


PDF for my MOBO: https://storage-asset.msi.com/datasheet/mb/global/H510M-A-PRO.pdf

Any help is appreciated!

The RX 6600 XT only uses x8 lanes. It is a limitation of the card.

So it's working as intended? 4.0 x8 is fine?

Like Omega says it only runs at x8, that's the maximum bandwidth.

Thank you so much guys, I was very worried something was up with my MOBO or my PC.

Yes because it runs on 8 lanes. My rx6400 only runs on x4 pcie 4.0. only four lanes. If you want 16 lanes you have to get x16 card.
