Notes:
1. Each AntMiner R4 has 6 PCI-e connectors for +12V/15A DC STABLE input on hash boards and 1 PCI-e connector on the controller, all the 7 PCI-e connectors are required. Do not connect more than one PSU to the same hash board to prevent possible damage and instability.
2. Power consumption figures will vary with your PSU's efficiency, the ambient operating temperature and the accuracy of the power meter.
3. Power supply unit is not included. The Antminer R4 can operate with APW5 as well as the APW3 power supply unit. To get the most out of the R4, Bitmain recommends the APW5 power supply.
4. Please download the latest R4 user manual from the "Downloads" sub-menu under the "Support" menu on Bitmain website's .
I just received my bitcoin nerdminer. It took a little bit of concentration to get it up and running. Getting the password to work was my biggest hurdle. I am going to purchase the solo miner next with hopes of actually mining coins!

Better than i knew it was
I ordered one Gamma from Bitcoinmerch, and another from competitor. The one for Bitcoinmerch took a couple months to arrive, the competitor a few days. However, on the Bitcoinmerch unit the unit ran cooler, quieter, and lower power. I noticed it had a better heat sink, and a better fan.

One of nerdminer 2 had issues but issue was resolved
I ordered the set with 7 nerdminer 2 and of them had issues from the beginning. I have been told to flash the nerdminer 2, I tried 50 times without success. I even tried clearing it and now my nerdminer 2 is not working at all. I was hoping they would send me one as a replacement and they did.
I changed my rating because bitcoin merch sent me a replacement nerdminer 2. This made my day!
