Is there a way to tell which GPU is in which slot? For instance, lets say I have a 5 card rig and GPU 3 is having issues. If I want to physically pull GPU 3 and try it in another rig, how do I know which card is GPU 3?
When the miner is running, you can press a number (0 - 9) to turn a card off or on. I just watch the fans, and start with 0, then 1, etc...
