AMD Radeon HD5770 with official AMD driver

Hi all,

I just installed Windows 7 64 bit Home Premium on my new 6-core Mac Pro with Boot Camp. So far no problems, except that I can't install the official Catalyst drivers from AMD/ATI's homepage - the installation goes through, however it fails with en error saying that the Video Driver couldn't be installed. I previously installed all Boot Camp drivers.

Anyone had the same problems already? I need the official AMD drivers because I have more than one display and want to group them with Eyefinity for gaming.

Thanx in advance,
CJ

2010 Mac Pro, Windows 7, Windows 7 Home Premium 64 bit

Hi CJ and welcome to Discussions,

in such case it sometimes helps to first remove/uninstall all 'old' driver files/remnants.
Either by using the "Software"-Tab from the Control Panel or something like the free Driver Sweeper http://downloads.guru3d.com/download.php?det=745 or the paid Driver Cleaner.

Regards

Stefan

Hi Stefan and others!

Uninstalling all ATI drivers and reinstalling from scratch didn't help - somehow the latest ATI display driver has an issue with the Mac Pro - however what helped was intalling the shipped Apple ATI driver (from Bootcamp) AFTER installing the latest official drivers - that way only the control manager installed first and after the error message the ATI driver that Apple delivers installed fine. So now I have an Eyefinity display array working flawlessly over 2 displays!

Maybe installing only the control center after the Bootcamp drivers would have also worked.

Cheers,
CJ
