Topic: CGMiner Confusing/Mixing up my GPUs (Read 1444 times)

I have confirmed this issue on a different computer, simply UNINSTALL, reboot, then reinstall the drivers, should solve the problem

I think this problem is fixed now that I reinstalled the drivers.  
Thank you everyone for your help
No i was not using crossfire.

Alright then, a few questions for you then:
First and most important, why the "-d 1" option? are you using two different cards that need different settings? With what i see, you are telling it to use the config file for just device #1. I would remove that and try again.
second, if the first doent work, can you post the whole config file?

What --gpumap option did you use exacly?

--gpumap 0:1,1:0 should do the trick.

Make sure your config file isn't conflicting.

dont run you cards in crossfire. this will reduce your mining speed for sure

If you are running the cards in crossfire, the cards will clockdown to the slowest card. If one card has to clock down due to heat, the other card must match its speed. I have had problems running in crossfire and sli before. If running crossfire, take them off and setup a fan on top of the cards to keep them cool.

good luck!

Hi there.  I have a couple of mining rigs working well, but on one of my rigs, it seems that CGMiner is confusing the video cards.  

I have confirmed the same problem, and it even happens in cgminer 2.97 all the way to cgminer 3.11.
I am running 2x7950s here

The problem is, say GPU 1 is overheating, it will downclock GPU 0, and not help the situation, because its slowing down the wrong GPU.

Here is a screenshot of this issue in action


You can see clearly GPU0 is in use (from the temperature), even though it thinks GPU1 is in use.  I have tried gpu-map and gpu-reorder and could not seem to solve the problem.

I am running Catalyst 13.1
