Hi,
I use dual 4870x2 cards in my system. When I run “aticonfig --odgc --adapter=all”, there is always an error message for adapter 2:
"get clocks failed for adapter 2".
While the other three cards are ok.
If I pull out either one card and run this command again, there is no error occured.
I have exchange the PCI-E slots for these cards. It still reports this error. I have tested this in OpenSUSE 10.2 and 11.0 operating system. The driver versions I used are from 9.4 to 9.6.
Best regards.
This is the output I get for a dual 4850x2 system:

Do CAL and amdcccle detect all 4 GPUs?
In amdcccle you should see screens numbered 1,3,5,7 in the display manager
For CAL, I wrote a little test program that reports how many cal devices were found:
$ ./caltest
CAL Runtime version 1.4.317
Found 4 devices. Using device 0.

The was the biggest problem I had. With the latest catalyst 9.6, I found I had to plugin a monitor to each card (or a DVI cable from a kvm switch) ... with catalyst 9.5 this was not necessary.
I am running Ubuntu intrepid on a MSI GD70-790fx motherboard, or an ASRock x58 deluxe. Both work with dual 4870x2 or 4850x2.

Hi emuller. Have you ever used dual 4850x2 in Windows XP? Do I have to plugin four monitors for these two cards with driver 9.6 or 9.5?
Thank you.
