Flashing Radeon HD6770 to HD5770

6 posts in this topic

Recommended Posts

Hey guys, The last time I flashed my video card from Radeon HD6770 to HD5770, It worked great on Snow Leopard. But not so much the same on Windows 7, It goes to a terrible resolution and disables aero. My assumption, is that Windows 7 stopped recognizing the video card. Does anyone know how to get it working for both Operating systems? My theory is if I do this:


Then it will work for both?

to 6770 or 5770 ?


if to 5770, yes, you can !





my flashed 6770 into 5770 work fine on 10.6.8/10.7.3/10.8 without any patched kext.

Okay, I kept everything the same except for the Video ID, which I changed to HD5570, and when I reset my machine I got an error message do I need to install the drivers and that's it?
