FPS Stutter

[ZigaPC]

Hi all, so I've recently purchased and built my first pc. But I get really bad FPS Stutters in almost every larger game. Here are my pc specs:

GPU : Strix 1070 Ti

CPU : i5-9400F

MOBO : B360M Bazooka

SSD: KINGSTON 240GB

PSU : Corsair C750M

HDD : 500 GB WD

RAM : Single Channel 8GB Corsair Vengence 3000MHz(I know my MOBO supports 2666 only but it was cheaper)

Games I play are Rust, ARK, Fortnite, etc.

Is that good? Also my OS is on the same ssd as my games
