Re: Claymore's ZCash AMD GPU Miner v8.0

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.

I must be really stupid but I can't see any difference between a fan at 50% and a fan at 100% on these cards.

There's another thing that can help you - with Rx400 you can make custom bios and among other things set minimal fan speed to a unique for this gpu number.
EDIT: and after setting proper -di order for claymore (you do it in conjunction with watttool - the order there is good) by disabling and anabling during runtime (you'll see activity drop from 100 to 0%) - you know it all
