When I install the drivers of two 4870X2 in XP x64 it can't boot except if I disable ONE of the four GPUs.
Is it true that XP x64 does not support more than 2 GPUs or that is just for Crossfire (NOTE: XP is limited to support 2CF Cards while Vista support 3)..

I can not get benefit of the third GPU..

Dam you AMD.. We pay 530$ for each card and you did not put a manual printed book with it.. Not even a digital guide!!

Uh, if you disable a GPU, you have 3. Just get the latest drivers and try switching slots.

**cough**XP64**cough**problem*cough*

Hey Di7, it was supposed to be supported since CCC 8.9, but many people still can get it work (quadfire), since it needed support from Microsoft aswell from ATI, and only ATI did it, you can expect problems...

Thats the link saying xp 64bit supports quadfire.

If x64 is the problem, you can get a 32-bit disc from Microsoft for $10 or so.
