I updated to this version last week and have had some issues with it. As it's non-downgradable, I'm stuck for now. But am I?
Some folks were able to resolve their issues after some fiddling, so I thought it might help to put these things together in one place, while hopefully receiving a better bios version soon.
To me, it seemed (and made sense) as if the issues were different among DDR4 and DDR5 boards, but apart from that the issues sounded familiar throughout the whole portfolio of motherboards.
As an idea:
TUF GAMING Z690-PLUS D4
Issue: Board doesn't boot.
Solution: Memory training takes much longer with bios 2004. Wait a bit longer, have RAM re-trained, then turn on MRC fast boot.
Issue: RAM won't boot at previous speeds / certified settings.
Solution: Thorough CMOS clear with onboard jumper bridge might play a big role in a major version leap.
