Flash MBP GPU

[rabidz7]

What would happen if I flash my late 2011 1GB 6770M GPU with this 512MB rom? Would it work?

Why do you want to do this?

The question is why? Your 6770M in the MBP already has a bios for Macs.

Looks like he's trying to flash a FirePro M5950 bios to 6770m.

M5950 and 6770m are the same so you're not going to see any gain, if not much, by flashing, unless you're running software that functions better with FirePro/Quadro cards.

I want to lower voltage and increase clocks.

Maybe I'm being pessimistic, but this sounds like a great way to turn your computer into a paperweight.

I'm not sure how graphics switching works on OS X, but if it's anything like on Windows, it'll just use the integrated graphics.

you are going to blind flash a vbios that is not supposed to work on macs, in a non mxm gpu

pal its a sure way of having a very heavy paperweight

get someone that knows how to modify vbios and ask if it can do something for you, svl7 from notebookreview and techinferno is a very trusted guy, however I dont know if he ever did any work on macs

Most likely the vbios is not on a separate chip. Most laptops have the vbios inside the main bios/efi.
If that's the case you will need to hack Apple's firmware to change the vbios, and you still need to get the efi part of the bios.

Most likely just nothing will happen, as the flashing application won't be able to do its job. But if its does, I am quite sure you will have a fried computer - Apple computers use their own customised firmware.
