This must sound stupid but I can't find a f*ckin clue anywhere, and I can't believe nobody has made this question before: how do you identify a specific gpu from 6 identical cards in a mining rig? The only thing special about this card is 10ºC more in GPU temperature. You can't tell it apart with your hand obviously. Is there any option in Claymore miner that can help with that?
A guy at work asked me the same question. The fastest method i suggested was to use Claymore to turn 1 fan to 100%.
So easy to do on the fly and map your GPUs that way.
