AP Initialization after microcode loading - after enabling xmp

Just put a new build together. MSI Meg x570 unify, 5900x, G.SKILL TridentZ RGB Series 32GB (2 x 16GB) 288-Pin DDR4 SDRAM DDR4 4000, rtx 3070. Factory bios everything boots and runs fine. I went into the bios today and noticed that my memory speed was running at the default 2133mhz. I enabled one of the default xmp profiles to run it at 4000mhz, rebooted, and now I receive error message "AP Initialization after microcode loading" 0_0. Anyone have any insight into why I may be receiving this message?

Just found the following thread where apparently this is a common issue with msi motherboards. When I did the bios update I used the latest stable release and not the beta release (because beta), but some users stated using the beta bios corrected this issue. Going to give that a go and see how it turns out.

Updating to the latest (beta) bios resolved this issue. I was able to enable xmp profile, and ram is now running at 4000mhz...nicccce.
