Ok so I've had only 1 680m in my m18x r2 for a few months and just today i received my second card. My master card has the following vbios: 80.04.5b.00.02 and I'm guessing that's slv7's unlocked one. So... I check the vbios version of my newly arrived card and it states it the same version. I'm not sure how this is possible if i haven't flashed it yet? I guess I wouldn't care if the core clock of my new 680m went above 719mhz... what's the proper procedure here? Am I not supposed to flash the new card so both vbios' match? Or is there a newer version of the unlocked vbios I should be using? Thanks for all your help in advance.
