Yes, thank you for the reply

I've already tried this, it give's me the same error "OUT OF RANGE" :/

But why it could be hard in AMD? I mean I'm trying to get working my video card...

I understand that you're trying to get your video card working, but with an AMD there's more. The kernel was written for an Intel processor. A patched kernel can give problems.

?

Read this post for an example:?http://www.osx86.net/topic/19281-graphic-artifacts-bugs-using-amd-hd-7770-on-mountain-lion-1084/

Also are you trying with the VGA port or DVI. DVI will be a better choice, maybe you need a DVI2VGA converter in that case.

My ASUS 4850 is working fine in Lion, but I'm using an Intel processor and you're using an AMD processor.

?

Maybe read these links can help:

Or ask help from gils83, he has a HD4850 running with Lion

One of the main "rules" of Hackintosh is: AMD CPU's are most likely not to work, that's why you'll see, that almost everyone with a perfectly healthy running Hackintosh are using an Intel CPU.
