are you talking about asic boost? regardless, either port works
you can have as much machines as you with the same address, the hashrate will combine.
if you want to separate some miners just put "address.S19" or "address.1" and that machine will show its own bestshare/hashrate
Thanks chillfactr. Just 2 x Canaan 1246's 83T was a thought for now.
Is ckpool only solo, or do we have the capability to merge/pool with others - don't see it. Got 1 machine on solo for now.
