Hello, i've bought RX 5700 two months ago and game to game im constantly observe downclocking issue, im tired tbh...

I was playing Gears 5 for 2 days straight, my thoughts at first was that game is heavy, that my gpu isn't strong enough for WQHD you know... I was constantly telling myself that 25-30 fps on ultra is ok BUT THEN i've saw this guy's video on youtube and i was really surprised. From that point i've tried a couple different drivers (20.2.1, 19.12.2, 19.10.1 - i've always using DDU in safe mode) even chipset drivers (didn't do anything), tried HDMI 2.0 cable, tried without FreeSync, tried with different power plans (Ryzen Balanced, Win10 Balanced, High perf - none of them fixed downclocking).

I have never used Chill, EnhancedSync, Anti-Lag, Image Sharpening.

My PC specs:

Windows 10 Home x64 1909

PSU: Corsair RM 650x

MB: Gigabyte B450m DS3H

CPU: Ryzen 5 2600 stock 3.4 GHz (tried 3.9 GHz allcore OC, didn't fix anything)

RAM: 8 GB x2 hynix MFR OCed to 2933 MHz (i've tried it stock 2133, no result)

GPU: MSI RX 5700 EVOKE OC

Monitor: Samsung C27JG54QQI (WQHD VA 144 Hz, DP 1.2a, tried HDMI 2.0), i've tried without FreeSync - didn't fix anything.

I DON'T HAVE ANY BLACKSCREENS AT ALL (never single one)

i've uploaded an example of downclocking issue.
