@Svan - looks good then, that all looks like exact edits I did for you!

Here's the three places where you see current "in-use" microcode with AIDA64 and HWINFO64 (two places, one in small CPU-z like window and one in the large AIDA64-like window)


For the G03VI is this AMD or Intel CPU system? Anyway, yes, go ahead and lets dump, that way you get familiar with using that, how it works on your system, and so you can find which version software works with that system too.
That way if recovery is needed then you have a valid backup already made and know what works and how etc

@Svan - Great, then it's as it looked, mod BIOS flashed in fully and is working fine
Start a thread for your other system, about the dump, and put all the details there especially chip ID, and I'll try to help you on it.
In regard to your 1, 2, 3 choices in PM, I forgot to reply. You can often just dump BIOS region via FPT and edit then reflash too, if it's an Intel system.

@Sober - if FIT tab is grayed out, then there is no FIT table in your BIOS.

@Keep3r88 - 406C4 is added to the BIOS in your attached image above, not sure what you mean you can't? What doesn't work?
I didn't check the file, since your image shows it's already added.

H20EZE breaks BIOS usually for something like that (CRC32 checksum usually). How are you flashing BIOS? I can do mod properly for you, but need to know how you are flashing first.

@Keep3r88 - send me programmer dumped BIOS and I will update the microcodes for you
Before you know it's the mods that are failing, and not your write process, please dump BIOS, erase chip, blank check, and then program the BIOS back and ensure that it works.
This way you know your write process is working with programmer, then if edit BIOS fails you know it's the BIOS edit not the programming of the BIOS with programmer.
