Question PC won't boot with XMP enabled ?

[paparei]

hello im recently switch to this combo
R7 7800X3D

Asrock B650e pg riptide

RTX 3080 Galax

Corsair Vengeance RGB 64GB 2x32GB
When my bios at 1.21 ver, I can use XMP 5600 profile fine, no problem.

But after i update my bios to 1.28, i turned on XMP, saved and restart. After that my PC wont boot up.
Is there an issue with 1.28 ? and should i update to 1.29 ver even though its in beta? Thanks.

did you read this info?
*First boot with XMP/EXPO enabled will take a longer training time than pervious BIOS.
Debug LED will stay at DRAM and flashing a few minute. After that, system will back to the normal boot speed.

so wait a bit longer than usual after flashing

because of the bios flashback feature of your motherboard, try the beta, if it won´t work -> flashback

yes i did read that, well i actually don't know how "longer" is exactly because for normal it took me like 30 sec and I'm been waited 10min+ or so.
i decided to downgrade to 1.24 And can use XMP like normal.
