What I did right?

I did managed to put together 4 GPU ethereum mining rig, which was running at 92 MH/s hashrate earning for me 12$ a day and used 500w of electricity. I also bougth a second PSU 750W for my next GPU. For now I have 5 GPU and room for 3 more. Becouse of recent price rally my MSI GTX 1060 6gb graphic card price went from 325 EUR to 405 EUR I haven't got those three, but that that will be later!

Overclocking

I am using MSI Afterburner to overclock my graphic cards improving hashrate from 17 Mh/s to 23 Mh/s per graphic card!

What I did wrong?

I bought a wrong motherboard!!!!! This MSI Z270 TOMAHAWK mobo don't support 6 GPU. I spent 2 days to figure that out, I changed BIOS, drivers, surfed through the forums and realized that it can't be done! So now I gave this mother board back to store and ordered another one! My rig will be down next 3 days and I wont be able to make money!

Now I am wating for my motherboard and will be running my 115 MH/s ethereum mining rig!
This is my experience into mining. Everyting I do is something new for me and I am learing a lot!
If there is someone out there also minig with rigs I will be thankful for the suggestions!

BACK TO MINING SOON!
