Noob question: If I have 3 x R606 miners, do I need to run 3 instances of cgminer? Or is there a way to run just one instance of cgminer and control all 3 miners?
If they are all linked to the same pc then a single instance of cgminer will pick them all up. However it will try to run them all at the frequency you set it to, which can be problematic if you have a unit thats not as fast as the others. But a single instance for each one means you can tweak them individually to get the best performance from each.
