It can handle as many as your miner can. I run 10 gridseed 5-chips on one instance and 2 gridseed blades on another.

A. Miner software questions should go here Mining Software
B. Um, ever tried looking at the 2PAC thread? As in the very 1st post where all your setup questions are answered?

Then why are you posting here? This is a local thread of course most of us will speak in our language . Or are you planning on moving here to simply mine bitcoin? If yes, It's a no because I am afraid that all of your earnings will just go to your electricity bill . The power consumption here is really high and in fact the rate is increasing every year so just find another place .

P.S. : If you will be posting in a local thread like this, Be sure to add that you don't speak or understand their local language and also please specify the reason .
