Hi guys I think I've fixed it after a few hours gaming now no crashes. My overall point stands that every other bench, game and stress test passes on my machine but BF6 seems to scratch a frailty somewhere and that this seems to be experienced by many going off forums. It seems to be people who are using XMP/EXPO by default (because why wouldn't you, it's what you pay for and is labelled stable with the platform you install it to).
I've found setting VDDSOC to 1.25 stable on Asus x670e(prime pro) / 9800x3d @ CL30 6000mhz 1:1. I think Asus bios was setting it too high by default and read somewhere that too much makes FCLK unstable. Very strange and I do think BF6 have an unstable engine in some way given literally everything else is fine for me.
I set VDDG CCD & IOD to 850mV just in case too low and I set CPU VDDIO/MC voltage to 1.3 as the Asus bios was setting it to something like 1.46 default which is surely too high and I read inversely affects FCLK stability). The final thing I can mention is Asus have an 'Asus Performance Enhancement' setting 'on' by default so I disabled that in case it was trying to pump anything beyond PBO which is enabled thereby causing instability. I set EXPO from I to II as well, seems to be same voltages/speeds however unless there's a hidden lower level timing change that impacted/helped
I use EXPO II so including subtimings and have no crashes.
9950x3d/5090/64 GB DDR5 6000 CL30/990 Pro 2 TB mainboard is ASUS TUF GAMING B850-PLUS WIFI with latest bios (1402) and chipset driver by AMD (7.11.26.2142).
