i7-8700K to 5 5600X - RTX 2080 performance halved

[kingmustard]

Old system:

• Intel Core i7-8700K
• Gigabyte X370XP SLI
• 16GB DDR4-3000

New system:

• AMD Ryzen 5 5600X
  • Latest chipset drivers installed
• ASRock B550M Pro4
  • Latest UEFI, dated Nov 6, 2020
• 32GB DDR4-3600
  • Until I sort it, I have stability issues when running at 3600 MHz (18-22-22-42) so I am currently running at 3200 MHz (18-22-22-42)

I noticed Serious Sam 4, which I was playing before I upgraded, was chugging and the framerates weren't as good at all.

 

I have ran a few benchmarks and can see that it appears my GPU is having issues.

 

Any ideas?

Hmmm, kinda weird but things you could try :

 

1) DDU nvidia drivers and reinstall (IF you haven't done that already)

2) Reset Nvidia Control panel just to be sure

3) Go to bios and change PCIE to PCIE-3.0 instead of 4.0

 

Personally that would be my todo list. After that it's hard to say.

I removed the NVIDIA drivers in Safe Mode with DDU and reinstalled but no change.

 

There appears to be no option in the UEFI to change the PCIe speed (I tried everywhere, including Advanced > AMD CBS > NBIO Common Options).

Ugh, is this one of those AsRock things again...

 

You could ask AsRock. Someone else had BSOD issues with a riser card that needed pcie3.0.

 

"BIOS > Advanced > AMD PBS > PCIe x16 Bus Interface (Auto/Gen1/Gen2/Gen3/Gen4)"  Pasted from post.

 

If you happen to have MSI afterburner you could check if the GPU can boost where it should. And if you still have BOTH systems up and running check if the clocks match. One thing you also could do is install older GPU drivers and check does that help, something like 3-4 versions.

I don't have "PCIe x16 Bus Interface" anywhere, unfortunately.

 

I have done as you suggested and posted on the ASRock Reddit

What PCIe slot are you using? GPU-Z is only listing an x1 slot. The B550M pro4 requires you to use the top slot for proper bandwidth.

The top slot. The reinforced one.

By the looks of your setup you have only 225 watts of power going into your GPU. It is designed to use 300 watts.

 

This is my 1080 ti connected to a RM850x. It has an 8 pin and a 6 pin like your 2080. I use two cables to get the 300 watts the GPU needs to perform properly.

I reseated the GPU and unplugged/replugged the GPU power cables and now it's working a treat

 

Thank you
