What size bios should I have 6770M GDDR5?

[Meaker]

ATIflash and GPU-Z both extract 64KB bioses from my board.

RBE warns that these could be too small (my card uses GDDR5).

Here is a screenshot of the extracted bios (left) a 6670 Desktop (same chip but on desktop) and a forced dump of a hex value 20000:

Any way of checking what I should be getting? If my forced bios has caught everything?

Looking at the files there does seem to be more code in the forced dump.

I've attched both bioses.

the second 64k of the bios seems to be the same as the first 64k

Is it possible this is a GDDR5 card with a 64kb bios size?

Went ahead and flashed, yep 64k size all working fine.

Are those files you posted the bios from the 6770? They do look like it, so I just want to make sure.

Has anyone here flashed a 5770 to the 6770 bios? If so, any word on how well it works? More specifically, will it enable HDMI 1.4 functionality?

Thanks.
