Hi there. Today I installed a second 5870. However it is not recognized by poclbm  Huh I used varios information scattered around the Wiki and the board . It is installed and initialized. Crossfire is diabled:

* 0. 01:00.0 ATI Radeon HD 5800 Series
  1. 02:00.0 ATI Radeon HD 5800 Series

* - Default adapter


On the first GPU i'm mining with no problems like before:


Adapter 0 - ATI Radeon HD 5800 Series
                            Core (MHz)    Memory (MHz)
           Current Clocks :    850           1200
             Current Peak :    850           1200
  Configurable Peak Range : [600-900]     [900-1300]
                 GPU load :    94%

Adapter 1 - ATI Radeon HD 5800 Series
                            Core (MHz)    Memory (MHz)
           Current Clocks :    157           300
             Current Peak :    850           1200
  Configurable Peak Range : [600-900]     [900-1300]
                 GPU load :    0%


But poclbm does not recognize the second GPU:


No device specified or device not found, use -d to specify one of the following

_[0]   Cypress
_[1]   AMD Athlon(tm) 64 X2 Dual Core Processor 3800+


using -d 1 uses the CPU which is way too slow ;-)

Am I missing something?

Hi all! I'd be grateful for help.
I have the same problem, but use another miner ( m0mchil's miner ) on win 7.
Two cards are shown as device 0.

Help please.  Sad

Now in bat file:
"start poclbm.exe --host=mining.bitcoin.cz --port=8332 --user=me.me --pass=pass --device=0 -v -w 128 -f 60"

What i must do?

Unfortunately this solution is Linux specific  Sad I had to tell poclbm which X-server it should use. Sounds a bit ridiculous for numbercrunching but i guess it's due to the fact that the GPUs are still graphic cards instead of a co processor from the ATI programmers point of view.

As you mentioned .bat files i guess you are searching for a windows solution... but perhaps my explanation helps you find the windows equivalent?!
