that´s a good point. I already recognized that if you have one GPU as GPU0, it will not stay GPU0 if you add or remove a card. I added 2 cards to my rig...I printed the GPU number with a label printer to the GPU´s...but you can forget everything if you edit the number of gpu´s...you need to find out with spinning fans which one is which one and set oc manually again. if one card crashes and the rig restarts without that card...your oc settings will be totally mixed...true ! good point.....but maybe a point for the operating system not to start the miner.....
but if one could add this to phoenixminer, would be great to see.
Thanks, I just made a powershell script that counts the display adapters using devcon.exe (windows) and shuts down the system after a timeout if it can't find required number of display adapters, or runs the normal batch. It's not fool-proof or as graceful as having it on phoenix miner. Haven't yet tested the script in real-life conditions yet, and don't know what happens if the drivers are disabled instead of a gpu/riser failure. Will have to test those some time.
I hope this kind of behaviour can make it into phoenix miner itself.
