I have issues almost every day I play on my PowerColor RX 5700 XT. Some of them are below.
All of these can be solved by reboot until next time.
I'm on latest version of both chipset and video driver, motherboard has the latest BIOS but I also had the same problems with previous versions.
I've tired to underlovt to lower the temperature (it's not more than 80 degrees now) and to disable FreeSync, I think both things made it slightly better but I still have the issues.
I have no issues on Linux with open source drivers. I mostly play Valve games (HL, HL2 etc.).
I contacted PowerColor, they said they can RMA but it will take multiple weeks and I will need to pay for shipping from Singapore to the US and back which is at least 20% of the price + I will need to pay 7% import tax. I don't want to do this without knowing that this RMA will actually help.
PowerColor support said these can be software problems and told me to contact AMD first, they said refund is not possible.
I've already reported the issue via AMD software but nobody contacted me regarding this.
Please contact me if you need more info to debug this.
Today I also got system crash (reboot) while playing Warcraft 3 Reforged. Event log says it was caused by Radeon Software.
My current settings are shown below but I've tried to use the default, default was less stables and very hot as it's overclocking the GPU (official PowerColor spec is 1755MHz(Game) / 1605MHz (Base) / Up to 1905MHz).
I have also tried to disable FreeSync and other display imrovements, it did not help (at least in StrarCraft)
