Upload your dump in bios section and request a clean me bios for same. There is already a detailed guide on how to clean me by moderator @smdflea.

@tsiga, i cant say this with cetainity but newer mb's requires clean me bios to flash. Just flashing a dump from working mb doesnt work on another very same mb-sometimes do work but with late display. So, better to flash a clean me bios to rule out bios issue.

So, you need to troubleshoot. Post schematic if u have. I'll recommend to check powergood of ram ic is present or not and DRAMRST# is present or not.
