Question FPS Drop from 60 to 5 after CPU upgrade

[jw.jsmith95]

Hello everyone,

I have bought new CPU last summer because I fuc*ed up my PC build and I would buy Ryzen instead of FX . So, I've been playing for years without any problems or any FPS drop before upgrade.
I have decided to upgrade my old CPU from AMD Phenom II X4 940 3,00 Ghz to AMD FX-8350 Black edition.
After upgrade I have noticed some FPS drop after a while in new games like mirror's edge catalyst, Tom Clancy's the Division, Battlefield 4, Assassin's creed Unity or Syndicates and even AC 3 or Black Flag and so on except Fortnite and some other MP games. First half an hour is 60+ FPS and then suddenly it starts to fall to 5-10 for few seconds and then again goes back up to 60 and for few minutes FPS drop happens again. My vertical sync is off in Nvidia control panel, preferring maximum power, every game has VSync off 'Cause if I turn it on it becomes even worse. What should I do? My all drivers are updated and I am checking on them almost every 24 hours. Even few times a day.

My system is:

AMD FX-8350 (I have unlocked all 8 cores and max temp is showing around 40-50°C + LC CC 95)
Nvidia geforce GTX 1050 Ti by Gainward
8 GB RAM 1866 Mhz DDR3
Windows 10 Pro 64
ASRock 970 Pro 3 R2.0 DDR3

P.S. Sorry for my bad english ♥

Most likely the problem is from your MB, because it has 4+1 power phase, they will overheat during the games.

Try disable two or more cores in the BIOS, and try the games again. If you don't get problem after disable the cores, then you will need to install the VRMs heatsink, like https://www.techpowerup.com/forums/...therboard-mosfets-mosfet-cooling-2-jpg.62294/

Or add the small fan on the VRMs section, like: https://encrypted-tbn0.gstatic.com/...1kR6yBQE3Qo3YpE_ALwKnkeKbSY0peWnHrclOGFpZcOqs
