Can anyone please help me with this? I have an ASRock B450 pro4-f motherboard with r5 2600x and a msi rx 570 8gb gpu. I have no SSD just two HDDs. But for some reason my gpu is running at 8x 3.0 instead of 16x 3.0. I'm just hoping nothing is faulty here. And yes I have put the gpu in the 16x slot. I have also reseated my gpu and cpu. I have never updated bios before so I'm a bit nervous about that and I don't know if motherboard has a backup bios if anything goes wrong. Not too sure if it would solve the problem. I have given the bios settings in the attached image. I have updated the graphics card driver twice and also ddu it once. So I don't Think it's a gpu driver issue.

Lots of graphics cards fall back to lower power states when idle.

 

Is it still running at x8 when you're running a benchmark i.e. Furmark/Heaven/3DMark?
