more cores less heat more cache and cheap on ebay
i think i remember something about the checksums, but "partnumber" doesnt ring a bell.
is there a version on the motherboard (rev 1, rev 2) it s on the motherboard, physically
check if the UD5 has a backup bios and the method to restore backup bios if it is indeed dual bios
use usb boot FreeDos to flash. flashing under windows is dangerous.
i m pretty sure others flashed a UD5 so something else is at play here.
then once u manage to flash the UD5, you ll have to modify the bios rom to fit the reference of your nvme (guide in the signature) and flash again
finally once u flashed, dont put the nvme yet, have to edit the bios settings to disable sata3 and special gigabyte raid and extra controllers, else it will conflict with nvme rom mod
keep us updated. goodluck.
edit : better idea. do u have somewhere the original bios you flashed on the motherboard ? check the name and ref and version, that might help you choose. i see 3 bios for UD5, 2 for rev 1, 1 for rev 2. id you revision, it s crucial, it s between the pci slots.
