    Help with dual 4870x2 cards in a system

    wgbljl

      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.
          Device Type = GPU RV770
          Max 1D Width 4294967295.
          Max 2D Width 8192.
          Max 2D Height 8192.
          Found 1024 MB GPU RAM.
          Found 625 MHz GPU device clock.
          Found 993 MHz GPU memory clock.
          Found 10 SIMDs.
          Wavefront Size 64 .
          Device open and ready.
          Found 944 MB available GPU RAM.
          Found 1217 MB available uncached remote RAM.
          Found 490 MB available cached remote RAM.
          Kernel compile and link sucessful.
          Device sucessfully closed.

          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.

              Thank you Emuller. You are right! But I am very curious about this feature.
              I remember that I have tried catalyst 9.5 after using catalyst 9.6 failed. It seems that it also does not work. Now I plugin another monitor for the other card.
