No needed the bios update for that, but i recomand to do the update, i've got the same problem from the start & i solved it by putting the memory random in the slots & tested it over & over again, one by one untill the system accepts & do the post properly... i guess it could be solved with just an update, but i"m not sure, i Always got memory problems in the beginning, don't know why, asus boards have also a very listed memory compatibility list in there manuals, learned to dl & watch before i by memory for a knew board though 🙂
