Hi,

 

I recently replaced my HD4650 with a faster HD5570.

 

The new gfx card uses the ATI5000Controller and the ATIX3000 kexts. The old card uses ATI4600Controller and ATIX2000.

 

Now the new HD5570 also runs good with the ATI personality I edited for the HD4650. This personality "Flicker" resides within ATI4600Controller and not the loaded ATI5000Controller, but it works.

 

- Could I miss some features of the HD5570 because the personality resides within the wrong ATI4600Controller (which osn't loaded)? It's detected as HD5000 series in the system profiler.

 

 

The HD5570 doesn't seem to work as snappy as the HD4650 on the desktop. So I already tuned the bios with higher energy saving timings. But it doesn't accelerate the desktop. Regarding the 2d performance of the HD5570 I have these questions:

 

- My computer is identified as MacPro3,1. Is there another better profile with an real Mac that has a HD5570 (or HD5670) inside?

 

- I read that the HD5670 and the HD5570 have the same core. So I changed the bios to be identified as HD5670. Still OSX identifies my card as HD5000 series. I read posts in the net where people have a hd5670 that is identified as HD5600 series by OSX. Is there a way to let OSX detect it as HD5600 series? Do I have to patch the device id? Is the device id inside the bios?

 

- I need a tool to determine the actual gfx card timings under OSX. What tool is available for this?

 

Thanks for info.

Have you tried Chameleon and AtiConfig? I found the best framebuffer for my Sapphire HD 5570 is Eulemur. See post 67.

toleda, thanks! Works great with your Eulemur config. The gfx card is now detected as "HD5500 series" instead of "HD5000 series" in the system profiler. So I guess more acceleration possibilities are enabled now.
