I think that we need to understand the core point of that amdgpu.ppfeaturemask=0xfffd7fff trick which helps me to avoid GPU lockups on Linux. The temperature of GPU is under 60 C before the lockups of Tomb Raider. No strange statistics when I enable AMD's hardware overlay on Windows. I have no useful games' logs both on Linux and Windows - everything looks like it used to be. If I try to play Tomb Raider 2013 on Windows nowadays the system still lockups but rather in some particular moments (for example when Lara takes a torch in the beginning of game) and reboots automatically after a few seconds. Also I can't enable overclocking mode in BIOS. MSI Afterburner doesn't help too because of A320 chipset. What does Linux driver's amdgpu.ppfeaturemask=0xfffd7fff parameter actually change? Why does it solve my problem? How could I activate the same thing on Windows? Radeon control panel doesn't provide me overclocking tab (new integrated iteration of Radeon OverDrive for Windows) because Vega 3 is integrated graphics.

Maybe it's an exclusive bug in AMD drivers for Linux and Windows that reveals itself only with this unique combination of Vega 3 and particular motherboard? Or maybe it's a problem with cooperation between AMD drivers and BIOS? And I remember that there were no lockups in SuperTuxKart game on Linux when I used older version of Mesa library in the beginning of 2021.

So this fact make me think that the problem is rather software related. And I have to just activate this mode - no need to actually overclock or downclock GPU. As far as I know this string enables Radeon OverDrive technology in official AMD Linux driver. If I add driver's parameter amdgpu.ppfeaturemask=0xfffd7fff to Linux kernel settings everything works just fine: no lockups, no any other bugs. Is it hardware malfunction of Athlon and/or motherboard? I have an argument against such proposition. I need to investigate this problem more deeply with your assistance. Changing of any BIOS settings doesn't help and I use fresh 6.60 version.
Of course I don't overclock APU because of limited A320 chipset. When I launch various CPU or graphical stress tests both on Linux and Windows everything works absolutely stable without lockups. When I start to play any games on Linux or Windows the PC lockups more or less randomly so I have to press reset button. And there is a strange bug with integrated AMD Vega 3 GPU. I use AMD Athlon 3000G APU on ASRock A320M-ITX motherboard. I need advanced help with my mini desktop. Hello, pals and gals! I'm advanced hardware/software user with 20 years of experience.
