@memphisobrien I'm glad I managed to help you. 
@MrGenius figure it out that the module VRAM_Info is where the amount of ram is stored. I opted to find a proper donor for your vbios (same module size (kinda implies same supported memory type)).
I have an idea about what value is actualy controling the amount of ram installed (in this particular bios case, no clue about others) but well I'm not sure it's only what I believe it is (i see no point for more than 1 value for the amount of ram, but there might be data regarding how that amount is obtained).
No clue why AMD decided to keep the amount of ram in the vbios and not use auto-detect for it.
Test one of the gpu with 3dmark or/and unigine valley (valley should be enough for your gpu). 1 hour max, if there are problems you will see them fast (crash or anomalies).
Check the temps.
Also if you play games look for texture anomalies (with amd it can easily be the drivers...) and/or artifacts.
If you see texture anomalies ( something like random white/black lines (or block(s)) ) try an older driver. (With my hd 7750 on Win 8.1 I can't use drivers newer than 15.6, 15.7 and newer result in random texture corruption, I can actually reproduce it easily in Dota 2 menu..., funny part is that I don't experience it with 15.6 and older or in Linux... so I put the blame on AMD drivers).
I have no clue what they actually do when they make the fake vbioses... so there can be other things that are not right in the vbios
. (But what do I say here... I've seen new gpus from well known manufactures that had problems...)
