So, to give a small amount of background, I'm A+ certified, Server+, and several other certifications along with having worked in IT for a little over 8 years and I can't figure this out, so I'm turning to you guys for help. I've tried everything I can think of and I'm literally at my wit's end. I upgraded from a 2700X and Vega 56 in June of 2020 that had no issues with this machine that has been a nightmare for me. It's hard to enjoy anything with constant micro stuttering and the sense that the game isn't running well.

Games are stuttering such as Jedi: Fallen Order, Call of Duty: Modern Warfare, Call of Duty: Black Ops Cold War, Call of Duty: Warzone, and many others. I've included some screenshots of what appears to be downclocking in Jedi Fallen Order and a video where I'm running the Unreal Engine 4.0 Elemental Demo and you can see an extreme stutter at the end when he hammers the ground. I've tried absolutely every remedy I can think of. Just a bit of background, I work in IT for a living and I'm A+, Server+, and several other certs, but I'm at my wit's end. I'm posting here as a last resort to see if you guys have any ideas.
Here is my User benchmark run:
Unreal Elemental Demo Stuttering (small stutters are due to screencap, not apparent on my pc) the stutters I see are massive like at the end of this clip:
Here is the correlating Performance stats screenshot from Radeon during that clip (the spike is when the stutter happens)
Here is a screenshot of a major stutter on the Heaven Benchmark.
GPU has been RMA'd - still stutters
PSU has been replaced - still stutters
OS has been reimaged - still stutters
Tried different RAM - still stutters
MOBO has been replaced - still stutters
Added liquid cooler - still stutters
tried every wacky youtube video out there - still stutters
disabled XMP, PBO, etc, etc - still stutters
Added more fans - still stutters
and many more things that I probably forgot about.
I'm starting to wonder if it has something to do with my CPU as it's one of the few things that haven't been replaced. Please if you guys have ANY suggestions that might help, I will try, I just don't know what to do anymore.
Please, can anybody make sense of this? See below for the constant frametime spikes in COD: Black Ops Cold War. Any help is appreciated.
