No one is fixing nothing at this point that is the reality. They are busy with the new lines of mainboards and even with those they are dragging their feet. They don't even read this forum at most you get a mod to send them a quick note and a link, that is the extent of the involvement from what I observed.
I have this issue on my own B650 Tomahawk and 7700X and G.Skill EXPO 6000 CL32 going on more then two and a half years now. There is no upcoming magical bios update.
I suspect at first I was okay, then a few months of running buggy over 1.3V spikes problematic bios (the first ones were bad, I have my PC since late 2022) it took out (degraded it just enough) my integrated memory controller of the CPU. So if I want restarts then I run 4800, if I want EXPO 6000 then no restarts. Most likely I need a new CPU to actually resolve this issue.
