Bitmain Antminer D3 - X11 ASIC Miner

Antminer D3 Miner

The Antminer D3 is Bitmain's ASIC miner for the X11 hashing algorithm.    X11 is growing in popularity so it is natural that the larger hardware manufacturer of crypto-currency miners has decided to enter the market with their commercial offering.  The D3's design is in the same line of all the Antminers since  the S7 miner.  The length is very close the S9 miner.  The miner has the same configuration of: three hashing boards, controller board, two fans and an aluminum case.   The units is a little higher than an S9 but outside of that, basically the same.

The web interface is the same Linux powered setup you find in all of the Bitmain offerings.  There are five mineable coins for the  X11 protocol.   DASH by far is the coin that almost everyone is mining with these units.   With the growing popularity of this miner, we could see the difficult spike significantly when this launch.  Each units takes 1,200 watts a piece.   On a 20-amp you can safely run two miners and potentially three miners but please note you will be 1.3 amps over the normal de-rating of 80% of the breakers maximum capacity.

Overall another solid offering from Bitmain and should do a good job mining for X11.

Bitmain Antminer L3+ (Litecoin SCRYPT Miner)

Antminer L3+ Miner

The Antminer L3+ is the ASIC-based 2nd generation offering from Bitmain supporting the SCRYPT hashing algorithm.  This algorithm is primarily used in mining for Litecoins, there are a number of other SCRYPT supported cryptocurrencies that support this protocol, including:  Gulden, Verge, Digibyte, Auroracoin, GameCredit and the famous Dogecoin.  Before Bitmain's entrance into in the SCRYPT market, KNCMiner was a major player in this mining hardware segment for the launch of the L3 miner series.  KNCminer's Titan series was their first ASIC miner that supported SCRYPT with a major jump in hashing performance.   

The L3 series is an even more significant jump in performance.  The L3+ is clocking in at over 500 Mh/s at only 800 watts per miner. One of the nice things you get with the magic 800 watts power draw number, is that when you run them at 208 volts or higher, you can fit four L3+ miners on a single 20-amp circuit.  That is a pretty big deal for large miners and crypto hosts.  People who handle large amounts of miners know that utilizing the most amps from your circuits is critical for infrastructure efficiency.  Four units per breaker makes this a good fit for doing co-location.   With these types of numbers, it is clear this will become the bulk of hashing power for the Litecoin network.  This still  have the same standard design you have gotten since the Antminer S7.  It is shorter than the S7 & S9.   

Same basic parts will need serving over time, this include: Front & Back fans, hashing boards, control board and rarely PSU.  These are easy units to breakdown and I could fully service a unit within 10mins.  Overall these are great mining units.

Bitmain Antminer S9 ASIC Miner

Antminer S9 Bitcoin Miner
The S9 Bitcoin miner from Bitmain is their newest offering in their hardware lineup.   Released in June of 2016, they are coming in a number of models.  The Antminer S9 miner models are available in different speeds based on the batch order.   Hashing speeds are: 14Th/s, 13.5Th/s, 13.0Th/s, 12.0Th/s and 11.5Th/s.  At the wall, the S9 miner consumes about 1,330 to 1,450 watts under full hashing load.  

The design is very similar to the Antminer S7 unit.  The S9 is a little longer than the S7 but outside of that, basically the same.   They both share the same administration interface that the entire Bitmain miner family uses.  It is a very simple setup to get the unit mining, estimated setup time is under 5mins once you have it plugged in and on your network.

The performance increase is amazing compared to the S7 miners.  With very similar power consumption, this is a major upgrade from Bitmain and these will become the majority of Bitcoin SHA256 mining power on the Bitcoin network.  Out of warranty service is still very high  with only a few parts to support or replace in the event of damage.   

Parts normally needing service after 12-18 months of service are:  (3) Hashing Boards, Front or Rear Fans and Control board.   Normally you will see one or both fan bearings go out and if they are hosted in a high temperature environment, you will see a hash board failure potentially.   Control board and PSUs have very low failure rates.
