Such combination is not recommended in AMD systems as you must use 2x2GB and 2x1GB memory stick to obtain it.
Which is not good idea[mixing memory sticks]
For best results and optimal performance, use 2x matched memory sticks only.

Go to reseller to sort for you.
Let him try with different memory sticks{AMD Tested}.
The message may gone by itself, often such fake message can come from bad or not compatible memory stick.

Make sure to change the extension to .ROM.
Nope, system is expecting original file name A7577AMS.200 as Bas mention as well.

Ah, I see. Thought it needed a .ROM, but I'm obviously wrong.
But if we already knew this, what's this whole topic about then?
Get the file on a stick and make it recover. Can't be that hard... ???

I would suggest to try with AMD regular memory stick 1st before attempt any BIOS recovery.
Else he really can kill his board, while attempt to recover healthy BIOS{Too possible to be memory error and not BIOS failure
[bad|not compatible memory stick can produce the same fake message.]
Also BIOS hardly can corrupt to this stage by itself, he tell never touched the BIOS:
