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...
Couple of things.
The HD6770M has only 8 rops, not 16.
Also when capturing the bios it only extracts the first 64KB.
This is a GDDR5 card and the desktop version (6670) has a 128KB bios so I think this should too.
RBE can't access the 3d clock settings on an HD 4770 bios and no tools can overclock either of the cards when they are in crossfire. Am I stuck until a new version of RBE comes out? I have tested each card and know what they can safely reach.
