RX 480 Bad Performance, used to be great

Hello, I have an issue with my RX 480 (Asus Strix RX 480 8GB OC), it used to have good performance: Doom 90 FPS +, BF 1 80-90 FPS, Far Cry Primal 70 FPS +.

I had to reinstall Windows and I also installed a new RAM stick, after this I got only 50-60 FPS in all games and drops to 10-20.

I have monitored the temps for CPU and GPU and both remain in good level, CPU 60° max and GPU 65° max, memory remains stable for GPU.

I have reinstalled drivers using DDU and the performance keeps low, I don't know what could it be.


Any ideas?
