Question High end PC - stutters/FPS drops

[Snusmakaren]

Hey!

I've tried to find similiar topics, and haven't been able to find an soloution to my problem.

Here's my specs:
CPU:: AMD Ryzen 9 3900X Processor 12 cores / 24 threads / 4.6 GHz
Motherboard:: ASUS ROG Strix X570-F Gaming - ATX / X570
Chassi:: Corsair Obsidian 500D SE / RGB
Power: Corsair RM750X V2 / 750W / 80+ Gold - Svart
Cooling: Corsair H100i RGB Platinum / 240mm
GPU:: MSI GeForce RTX 2080 Super Gaming X Trio 8GB
Memory: Samsung SSD QVO 860 2TB
OS:: Windows 10
RAM:: Corsair Vengeance RGB PRO 32GB (2x16GB)
Extra fan: Corsair LL120 RGB / PWM / 120mm / 1-pack / Add-on - Svart

So I do experience stutter and FPS drops in...honestly...all games. The PC is kinda new, bought it just some months ago. So I play games such as Battlefield, World of Tanks, LoL, Assassins Creed etc...The FPS drop lasts for 1-2 seconds, then everything is normal again, it doesn't matter what kind of settings I have, I do still get it, I mean, I shouldn't even be able to get it?
This is happening every day, every game I play. My old PC, which is 100 % worse, didn't suffer from these FPS like I do now, it's so odd. I can't seem to understand what the main problem is...

Things I've tried:

• Disable Xbox game bar- no difference
• Clean my pc from dust - no difference
• Uninstall iCue - no difference
• Tried another monitor - no difference
• Disable shadowplay in Geforce experience - no difference
• I have updated every single driver you possibly can upgrade - no difference
• Disable USB port 3.2 - no difference
• Did a sfc/scannow, found nothing - no difference
• Closed background programs - no difference
• Turned off diagnoistic policy service- no difference
• Reduced graphics - no difference
• Uninstalled MSI Afterburner - no difference
• Put battery power - to prefer maximum performance
• Tried vsync on and off - no difference
• Scanned my pc for viruses - no difference
• Reinstall windows - no difference

My temperature while gaming seems to be fine, I get my GPU temp around 50 % and my GPU usage around 98 % in Assassins Creed oddyseus. Similiar result in the other games. my CPU temp is around 62 % and my CPU usage is hard to say, considering it jumps around a lot.
I've spent a lot of money and time on this PC, I did not build it, the company built it. I have tried most of the things I can think off. There shouldn't be any problems with this PC, considering the specs.

All help is appreciated, and thank you for taking your time to read this.

You have two different types of RAM, that's probably the culprit no?

My bad, posted it's full name. No different types of RAM.

Maybe run ccleaner and use the tool that checks for problems in your registry. When I lasted scanned I found a ton of problems with my registry.
