FPS drop/microstutter debugging after replacing 95% of the PC and multiple re-installs

Can you explain the problem you had with amd in fine detail ?

Fine detail? That EVERY game had stutters like crazy no matter the settings/GPU/mem and other things I changed. The best visible way to see it is to watch the video in my post.

I replaced AMD CPU and mobo with Intel and the problem is fixed. All other components are the same, not sure where the issue is, but it has something to do with AMD chipset or CPU, and no updates or settings I tried resolved the issue.

wait.. did you change cases also?

Change? No. But I ran with all case plugs disconnected except the power. I also ran it with no case as I was changing out motherboards and had the same result. There is no doubt that it is 100% an issue with the CPU or Motherboard.

I had similar issues on 5950x and 3090. I was able to find settings that helped, and after weeks of changes the problem has been resolved. I think the setting that fixed the occasional freezing like the video shows was turning off XMP in BIOS.

Hi there! I have a friend with the exact same issue on iRacing. He’s on an AMD 3700x, 3080, 32GB of memory, and an Intel 660p.

My question is when you when to the Intel hardware did you also upgrade that Intel 660p? I’ve noticed in my Google searches many cases of stuttering and the 660p come up in a ton of them.

What do you think?

I did replace the Intel 660p with Samsung 980 Pro, it made no difference with the problem that I was having.
