[SOLVED] Heavy stuttering below 60fps. Can't be VGA, SSD or Monitor problem. Its either the Mobo, CPU, PSU or RAM. Please help me identify the faulty component

Hi, I'm in a month old struggle with my PC. The problem is this:
https://streamable.com/jggtt (1440p, smooth 60fps, but below its stuttering)
https://streamable.com/nu2zb (1080p, locked 59fps 16.9 ms frametime, same stuttering)

So basically before this I enjoyed stutter-free gaming on my rig, over the years I had several GPU's (1070, Vega 56, 1080 etc), all worked fine. But for some season about a month ago I noticed stuttering in games, firstly I thought its the games, but then I tried other games in my library and all of them have stuttering. Almost all my games are without stuttering at stable 60fps, but as you can see in the videos, below 60, even at 55-59 they stutter heavily. Other games have stutteing even at stable 60fps 16.6ms frametime.

The things I've tried:
  • reinstalled windows to another SSD (so i have the same problem on different SSD's)
  • tested with other monitors (1080p60Hz Fujitsu monitor, 4K60Hz LG monitor, Oled 4K LG TV)
  • tested 4 GPU's (RX 560 4GB, RX 570 4GB (this is the GPU in the videos), 1060 6gb, 1080 Ti), all with the newest drivers, previous drivers deleted with DDU.
  • tried turning vsync on-off
  • downloaded the newest drivers for the mobo, and updated BIOS
Nothing helped. One thing that is worth a mention: my 4K60Hz monitor has freesync, and some better optimized games, like Tomb Raider 2013 are running smooth in the freesync range (40-60fps) with the RX 570. But others, like AC Black Flag have heavy stuttering with the same card in the freesync range.

My specs:
GPU: RX 570 4GB/EVGA SC 1080 Ti
CPU: I5 6500 (I know its not a recommended CPU for todays standards, but gaming at 4K with a good GPU I had no problem with it so far (before a month ago, when the stuttering began), as at 4K the GPU is doing most of the workload)
Mobo: Gigabyte GA-B150-HD3P
RAM: Crucial 16GB DDR4 2133 CL15
PSU: Cooler Master G650M 650W
SSD: Samsung 860 EVO 250GB
Windows: newest Win10

Do you have any idea what could cause it?
If there is no solution, then I'd buy a 3700x/3800x with an x570 mobo, but even then what if its the PSU or the RAM that is cousing the stuttering? What would you do in my place?
 
tell me what's the temp of you CPU ?
I can see 3 ways this can happen:
THERMAL THROTTLING
or
SINGLE CHANNEL RAM
OR
WINDOWS configuration.

if its TT, temp of your CPU should be above 70 while load and AIDA(great tool) will show this:

red line means cpu is overheating.....

if its single channel ram, (1,3,5 sticks, wrong seating, different sizes) then you need to adjust ram to do MATCHING PAIRS.

if its windows, here's a tutorial:

and a reminder
NEVER SET MINIMUM TO 100%, YOUR CPU NEEDS TO COOL DOWN SOMETIMES to boost when you need it.
config should be
100% max
10-15% minimum

even 99% in max means cpu will not turbo, so you use 2.5Ghz instead of 4Ghz when you need it.

@Rdslw
In my streamable links yu can see that the temps are below 50, so thats not it.

My RAM is 2x8GB matching pairs, and I just ran a 2 hour long memtest (people say that I should run it longer), no errors.

Tried the last one, set the minimum to 15%, didn't help.

Appreciate the effor tho

Ah, yes. I am thinking that's it. Might want to defragment and run some tests in the drive (whatever tests are available from the manufacturer). One test to run would be to put to one of your games in the SSD and see if the stuttering stops.
