Annoying stuttering on some games - High End PC-!

[KhaderKh]

Hi, 

I have the below specs:

 

i7 9700k@ 5.00ghz @1.3v w\ AIO 240mm

Asus Prime Z390M Plus

2x8GB DDR4 3000mhz HyperX Predator

Gigabyte rtx 2080super gaming OC

Seasonic Focus FM 650W Gold 80+

2K Screen

 

I have stuttering issue in some games like:

 

NFS Heat

COD BO4

Mafia 2 and 3

A way out

Two point hospital

COD MW (the new one)

Planet Zoo

 

Other games dont stutter:

 

Shadow of war

Shadow of the tomb raider

Anno 1800

Overwatch

Total War Warhammer 2,Three Kingdoms and Troy

 

The stuttering is not on all games but its annoying

 

I tried everything:

 

- Changing RAMs, Slots...etc

-Temps are fine across the PC using HWINFO, MSI AB

- Bios to default - No OCing-

-Multiple Bios versions and multiple drivers for GPU

-Ran Aida64 stress test, 3d mark, userbenchmark... all fine

 

I have cable mods, tried the original with the same issue.

 

Sometimes I can hear coil whine and when stutter occurs in that 1ms the coil whine disappears. 

 

A friend of mine told me it might be motherboard issue!!

I wonder if your 2080Super is hitting its PWR-Wall and instead of dropping 15Mhz, it may 'skip' a little dropping 30-45Mhz in an instant, and back up..
A flat graph with a single 1ms spike, random/occasionally would have me believe so.. (Seen on my 2080Ti also)

Yes its hits the 250 power limit, I need to check spikes in core clocks.
