MSI GT72 6QD bios unlock

[Zibri]

Hello!
I wish to unlock the OC (just for testing) and other menus in my bios..
But I have a few questions...

1) I downloaded afuwin 3.5.4 dumped firmware.
2) run amibcp 4.55..which crashed on saving.. so I downloaded afuwin 5.03 which worked.
3) in amibcp I just selected SETUP and on the right column modified OC from default to USER.
4) saved bios.

Is this the correct procedure? Do I flash it with afuwinx64 again?

Attached the original (1782.rom) and modified (1782oc) bios.
