Ryzen 7 Fps Drop and Stutter

Hi,

 

I am experiencing fps drop and stuttering problems with my ryzen 7 1700 setup in games Battlefield 1, H1Z1, Gta V.

 

My problem is same with the below Youtube link. You can see the problem in time code 9:35:

AMD Ryzen 5 1400 @ 3.8GHz & RX480 8GB Oyun Performansı ( Game Benchmarks ) - YouTube

 

I installed latest Amd chipset driver. All Windows 10 updates applied. My motherboard's bios is at F7 version.

 

I am curios about that is this a common issue with Ryzen or still memory compatibility issue?

 

My system spec:
