ATI Mobility 4870's Driver

I'm having a hell of a time trying to install the 10.6 Catalyst Drivers. When I do manage to get it installed CrossFire doesn't work and when I go to the device manager, both cards are listed but one of them is marked as unable to start or something, driver installed.

Anyone have any ideas? I've checked the driver forum stickied and I did the method one person suggested there, however, same result.

If you call AMD technical support level 1 they will probably tell you to go to Dell for a video driver. If you ask to speak to a level 2 tech they will probably tell you that the Catalyst Mobility drivers will work for some Alienware systems and not for others depending on your hardware. When you ask them which systems it will work on and how to tell the difference they will probably tell you they don't know.

I assume you tried the catalyst mobility drivers as opposed to the catalyst drivers and know the difference. Many people with your system have had success with the driver and many with dual 4870's have failed. I have often wondered if different countries are being shipped slightly different hardware or different drivers as it doesn't make sense that this fails so frequently for some but also works so frequently for others. Why does AMD say it will work on some Alienware M17x R2 and not others? Maybe it works with some motherboards and not others?

Try rolling back to the 10.5 and see if that works. From what I have read they seem more reliable than the 10.6

 

For 4870's - 10.3 was the best, IMHO. At least on my system it behaved better than 10.4-10.6.

 

I couldn't get 10.6 to work right, tried for a while too. 10.5 has been pretty good to me so far.

 

If you have the a05 bios It will not work correctly I use a02 and they installed fine.

 

I have the 4870's, i720, and A04 bios. I spent an entire day and half trying to get 10.6 to install and never got it working. Even reformated my computer. As has already been said though, there have been a lot of complaints with 10.6 so it's not a big loss any way. Maybe with 10.7 ATI will break their habit of putting out crap drivers like their last three.

 

when i try install 10.6 with defaul instaler setting i had also problem to install driver.
I choice install to program files (x86) and was succes strange
