Hello, i've bought RX 5700 two months ago and game to game im constantly fighting low clocks issue, im tired already... I don't have this problem in World of Tanks (will update game list when retested)
I was playing Gears 5 for 2 days straight, my thoughts was that game is heavy, 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'm speechless. 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 (nope), tried without FreeSync (nope), tried with different power plans (Ryzen Balanced, Win10 Balanced, High perf - nope).
I have never used Chill (tried once for Gears 5 with 141-141 range - didn't do anything), EnhancedSync, Anti-Lag, ISharpening.
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 4.0 GHz allcore OC, didn't fix anything)
RAM: 8 GB x2 hynix MFR OCed to 3000 MHz with tightened timings (i've tried it stock 2133, no result)
GPU: MSI RX 5700 EVOKE OC (with crap thermalpads - 1st revision, memory temps while gaming is 94 degrees Celsius)
Monitor: Samsung C27JG54QQI (WQHD VA 144 Hz), i've tried without FreeSync - didn't fix anything.
I DON'T HAVE ANY BLACKSCREENS AT ALL (never single one)
But i have brightness flickering with FreeSync (im at peace with it already, tho its a panel problem)
i've upload a video of this mess
I can add any additional info about my system if needed.
Strange that in-game it tells GPU Usage (lowest left text - Предел графического процессора) 99%...
I've run superposition bench with 4k optimized preset and according to GPU-Z my RX 5700 holds 1650-1700 MHz clocks.
