Print Page - miners (cgminer and poclbm) don't see the second GPU.

Hello. I've got two display cards:

Code:

$ aticonfig --list-adapters
* 0. 01:00.0 ATI Radeon HD 5800 Series  
  1. 04:00.0 ATI Radeon HD 5800 Series  

* - Default adapter

But CGMiner only see one device:

Code:

$ ./cgminer --ndevs
 [2013-04-14 10:35:21] CL Platform 0 vendor: Advanced Micro Devices, Inc.                    
 [2013-04-14 10:35:21] CL Platform 0 name: AMD Accelerated Parallel Processing                    
 [2013-04-14 10:35:21] CL Platform 0 version: OpenCL 1.2 AMD-APP (1113.2)                    
 [2013-04-14 10:35:21] Platform 0 devices: 1                    
 [2013-04-14 10:35:21] 	0	Cypress                    
 [2013-04-14 10:35:21] 1 GPU devices max detected

Poclbm on the other hand, shows some enigmatic message:

Code:

$ python2.7 poclbm.py 

WARNING: no adl3 module found (github.com/mjmvisser/adl3), temperature control is disabled


OpenCL devices:

[0]	Cypress
[1]	AMD Phenom(tm) II X4 945 Processor

No devices specified, using all GPU devices

It confuses me much. If my Radeon HD 5800 is recognized as "Cypress", then both should be Cypress. If my Radeon HD 5800 is recognized as "AMD Phenom(tm) II X4 945 Processor", both should be that, too. They are two identical card bought the same time from the same vendor, from the same shipment.

Having one as "Cypress" and the other as "AMD Phenom(tm) II X4 945 Processor" makes me believe poclbm also only recognized one of the video cards. I would be able to verify this if I can mine with poclbm, but I cannot, which is another topic: https://bitcointalk.org/index.php?topic=175691.msg1828977

Thanks!

And you are certain that 'AMD Phenom(tm) II X4 945 Processor' is not just the CPU?

Well, Okay, I misread it. I thought it is a GPU. But that reenforced the question: why miners only see one GPU? It is clearly identified as many graphic cards in aticonfig output. I should see more "Cypress" there, but there was only one. The mystery is still not solved.
