Good, now try to flash 1515 BIOS. It contains AGESA 1.0.0.7b, which you can Google what has changed. The rest of the BIOS is probably the same. I only see a different boot logo. Anyway to me 1515 made memory much more stable and I can now actually use restore memory context option, which reduces boot time to about 5s

The firmware does not exist. I already have it on it and it's stable.

If there is ANY black screen issues and you have an RTX 40xx card, it is 100% the power cable to the card itself. I had the exact same issue, the sense wires (2-4 tiny wires) don't make good contact and through thermal expansion/contraction, they can disconnect and it causes the GPU to drop offline as a safety precaution. This was producing endless nvidia driver error logs, as well as frequent sudden reboots and other issues.

If you have a cablemod cable, they know about the issue as well and will refund your cable if you order a replacement and cut the old one.
