Hello everyone! Today i realized, that my Sapphire pulse rx 580 8gb GPU what have pci e 3.0 x16 ,running at x8. My motherboard is Asrock A320M-HDV. It can handle the Pci-E 3.0 X16. So how is it possible that the gpu running like this? I have very low fps all games on 1024x768 settings too!! I think because of this thing.  i have the newest bios version on my motherboard. I do not have any nvme , just a sata winnchester.

| Look in the bios advanced settings for PCIe x16 Bus Interface. It is probably set to Auto. Try forcing it to Gen 3. In mine it is under Advanced - AMD PBS but I have a different model mb. |

| Well the only other thing I can think of is if you have any other card in one of the other 16x slots, even a USB ports add on, that can slow down all the other 16x slots. What other cards in other slots do you have installed? |

| I do not have only one pci e 16x port. And every other hardver like audio card or something like this is integrated. Do not have nvme. |

| Sounds like you need to contact the video card manufacturer. |
