AntMiner S9

Characteristics AntMiner S9

Antminer S9

Model S9 the most popular brand of "ashik Antminer, defined the main features of miners not only the manufacturer Bitmain, but also competitors. Beginning with the 9-series on a 16nm chip, its number has only changed in the larger side with the release of a new, more modern chip.

The material of Antminer S9 case and subsequent devices was aluminum in a rectangular form factor with coolers on the front and back panels. The fans provide efficient air cooling of working nodes with an optimal number of fans.

The Antminer S9's parallel layout, which was repeated for all other models, simplified chip replacement and repair, and allowed for the installation of heat sinks between the chips to dissipate excess heat.

Antminer S9 works with the following parameters:

• Working algorithm: SHA-256
• Cooling system: air
• Type and number of processors: BM1387, 16nm
• Hash rate: 11-14 TH/s
• Power consumption: 1400W
• Energy efficiency: 96 J/TH
• Operating temperature range: 15-35C
• Noise level: 76 dB
• Weight: 4.5 kg (without PSU)
• Dimensions: 350 x 135 x 158

Wide range of hash rates is due to different years of hardware production. The first models of Antminer S9 heated up to 90 C because of its high computing power, which forced Bitmain to limit the ASIC-miner parameters by means of software.

Over time, independent developers have selected the optimal frequency values for operation without severe overheating with a high hash rate, most fully revealing the possibilities of the 16nm chip. These custom firmwares are available for installation in a special section of the website.

Antminer S9SE.

At the end of June 2019, Bitmain released a special build of the Antminer S9, which received the index SE (Special Edition). ASIC miner was assembled on the same 16 nm chips as the whole Antminer 9 series, but it showed higher hash rate and energy efficiency.

The special offer included a relatively low price for the hardware at that time, which led to the sale of the first batch in a few hours. In fact, even then Bitmain began to develop a relationship with miners, when the prepayment was ahead of the fact of delivery by several months.

 Antminer S9SE specifications:

• Working Algorithm: SHA-256
• Cooling system: air
• Type and number of processors: BM1387, 16nmX189pcs
• Hash rate: 17 TH/s
• Power consumption: 1280W
• Energy efficiency: 80 J/TH
• Operating temperature range: 5-50C
• Noise level: 76 dB
• Weight: 8 kg
• Dimensions: 350 x 135 x 158

Since the release of Antminer S9SE, independent developers have selected and tested many settings of processor frequencies and hash rate characteristics. The most optimal values were included in the customized firmware, posted in a special section of our website.

In contrast to the stock software by Bitmain, the custom updates allow you to work with the increased profitability, without compromising the ASIC-miner performance. The miner returns the investment faster, can choose used models, reducing the threshold "cost of entry" into mining.

Antminer S9K

The "K" model in the Antminer 9 series appeared as Bitmain's experiment in the use of FinFET chips from Taiwanese manufacturer TSMC in mining.  The 16nm chip uses high-density transistors that increase SHA-256 algorithm computation speeds while consuming less power.

The Antminer S9K, released in the fall of 2019, attracted miners at a relatively low cost with higher specs in the lineup:

• Working Algorithm: SHA-256
• Cooling system: air
• Processor type: 16nm FinFET
• Hash rate: 14 TH/s
• Power consumption: 1250W
• Energy efficiency: 85 J/TH
• Operating temperature range: 15-35 °C
• Noise level: 76 dB
• Weight: 4.5 kg (without PSU)
• Size: 350 x 135 x 158

The above specifications are based on the Bitmain mining software defaults. The years of hardware exploitation allowed the independent developers to select the optimal settings, which give the most complete opportunities of the 16nm processor.

On our site posted custom firmware, which opens the owner Antminer S9K access to work on an increased hashrayte. This will increase the profitability of mining and accelerate the return on investment.

Antminer S9J

The Antminer S9 variant with the index "J" hit the market in late summer 2018. The manufacturer Bitmain presented it as an upgrade of the basic model S9, where the problems revealed in the course of operation were solved and the possibilities of the 16-nm chip were expanded.

As a result, Antminer S9 J "out of the box" produces the following characteristics:

• Working algorithm: SHA-256
• Cooling system: air
• Processor type: 16nm BM 1387
• Hash rate: 14.5 TH/s
• Power consumption: 1350W
• Energy efficiency: 93.12 J/TH
• Operating temperature range: 15-35 °C
• Noise level: 76 dB
• Weight: 8 kg
• Dimensions: 350 x 135 x 158

Compared to Antminer S9, the manufacturer managed to raise the profitability of the assembly "J" by 30%. This result can be increased by using the custom firmware on our website. These updates are the result of years of selection and testing of optimal parameters by independent developers.

The characteristics are tested and the custom firmware will not disturb the normal operation of the equipment. At the same time they will increase the profitability of mining and the rate of return on investment.

Antminer S9I

In 2018, the manufacturer of ASIC miners actively experimented on the most successful series Antminer 9.  The letters in the name assigned to the models indicated specific changes. The release of Antminer S9I was an attempt to work on energy efficiency through design solutions, without changing the basic chip - 16 nm.

Bitmain put a new kind of fans on the cooling, the use of which led to the following characteristics of the Antminer S9I

• Working Algorithm: SHA-256
• Cooling system: air
• Number and type of processors: 189XBM 1387 (16nm)
• Hash rate: 14 TH/s
• Power Consumption: 1375W
• Operating temperature range: 15-35C
• Noise level: 76 dB
• Weight: 4.2 kg (without PSU)
• Size: 350 x 135 x 158

As you can see the above parameters, Bitmain managed to achieve an increase in hash rate compared to the basic version, due to overclocking processors, solving the problem of overheating with the help of new fans. In 2018, such performance was considered a breakthrough.

Years later, independent developers created custom firmware that increased the hash rate and/or reduced energy efficiency, which can be found in a special section of our website. These programs will allow miners to increase the financial return of their mining operations and accelerate the return on their equipment investment.

Antminer S9duo

Model Antminer S9duo appeared as a result of a private upgrade of basic ASIC-mainers Bitmain. Independent developers realized the launch of Antminer S9 with a single control board and a single power supply. The modification successfully works in "dual" mode, giving double hash rate with optimal energy efficiency.

The S9duo concept has found widespread use in farms, allowing by doubling to solve the problems of repairing faulty control boards and creating a stock of power supply units. Split of two Antminer S9 miners is easy enough, the process is shown in details on our Youtube channel.

The working version of Antminer S9duo produces the following characteristics:

• Working algorithm: SHA-256
• Cooling system: air
• Number and type of processors: 378 BM 1387 (16nm)
• Hash rate: 20 TH/s
• Power Consumption: 1500W
• Operating temperature range: 5-40C
• Noise level: 2X76 dB
• Weight: 12.5 kg
• Dimensions: 2X (350 x 135 x 158)

The custom version of Antminer S9duo requires a special update to monitor and control mining on a common split control board. On our website you can find time-tested and many tests custom firmware, for the model Antminer S9duo.

The update will set the optimal parameters for dual ASIC-mainers, prolonging the life of boards, processors, power supply and air cooling system.  The received hash rate will increase the speed of working off of the invested investments and increase the expediency of purchasing of used model.
