Micro stuttering in Games

xDTrammell · June 15, 2021

So I have been trying to diagnose issues with my system for a few weeks now and I am at a point where I would like to get some ideas from some other people.

I have been having an issue where when playing games my frame times will spike to 80 or 90 ms randomly for no apparent reason. This only happens for a second or so but if you are playing a completive game this can be the matter of life or death. I first noticed the issue in Apex Legends and then after that I started to notice it in Call of Duty, as well as other games. Apex legends seems to be the worst but unfortunately is the main game I play at the moment. I have spent hours coming through every guide put out to try and improves fps in Apex to no avail. So I started looking at hardware issues, when I first got my PC I had issues with applying the DOCP/XMP profile where the system would not boot with it enabled, I thought this was a BIOS issues as it was such a new platform when I got it in December so I waited for BIOS updates to see if the issues would be fixed with patches. Things seemed to get better as bios updates were released I was actually able to enable the DOCP profile but sometimes when rebooting the pc it would not boot without resetting the BIOS. I recently purchased new RAM because I found other forum post of people having similar issues the ram I had before was CMW32GX4M2C3200C16.

When I ordered the RAM I didnt get the 2nd set until the next day so the first day that I got the new set of RAM the issues seemed to be fixed and everything was running stable. When I got the second ram kit all of the stuttering came back in games. So the system seems to have issues whenever I introduce 32GB of ram to the system as that was was the ram kit before was 32GB as well.

I wanted to ask if you think my next step should be to RMA the motherboard? If anyone has any suggestion please let me know.

Specs:

Motherboard - Asus Prime X570 Pro

CPU - AMD Ryzen 5900x

GPU - Nvidia RTX 3080 (Founders Edition)

RAM - 2 Kits of G.SKILL 16GB (2 x 8GB) Trident Z Neo Series (F4-3600C14D-16GTZNB)

Are you by any chance using Resizable BAR feature? That thing works like pure garbage on NVIDIA cards. With ReBAR enabled, Borderlands 3 runs like an absolute turd. Constant stuttering, lagging, even half a second long pauses. God knows how other games are affected, but it seems Borderlands 3 is one of worst offenders. And I'm seeing similar in Necromunda: Hired Gun which makes me believe anything based on Unreal is affected. And if entire engines are affected, god knows what else is also affected. Could be Source too which is used by Apex...

I was using that at one point but I disabled that as well and the problem still persisted. I had an issue when I first got the PC with an awful audio crackling that was solved by setting my PCI slot to gen 3 instead of gen 4 which fixed that issue at the time this was later solved with a bios update but I gave that a try again for this issue and that did not help either.

Edit: The only things that seemed to have help so far were buying the new ram kit, this has allowed me to have my DOCP profiles enabled with no crashing and no stuttering and then when introducing the second 16gb kit the stuttering issues return.
