Thanks, the reason I asked was because on the whole games are playing fine, except Death Stranding, after an hour it would crash with an error quoting both Nvidia and AMD drivers (but maybe just because I have both installed).
There is a known EXPO / SoC voltage issue since the recent BIOS patches, previously WHQL were updated and my kit was removed lol it won't do EXPO but the RAM plays nice at one notch lower speed below on custom timings, I put it through all kinds of stress and fine. I have also yet to try b and c BIOS versions.
I'll see if I can disable iGPU and uninstall the AMD graphic drivers and test again thanks.
