Antminer S9K, S9SE Evaluation

Antminer S9K, S9SE Evaluation

In June 2016, Bitmain released the Bitcoin Antminer S9, using 189 Bitmain self-developed BM1387 bitcoin miner chips of the latest generation, with a hash rate of 11.85 TH/s, a power of 1172W, and a power consumption ratio of 100W. /T. The BM1387 chip is the fifth-generation bitcoin miner chip independently developed by Bitmain. It adopts TSMC's 16-nanometer FinFET process and is designed with a fully customized solution. As a result, the maximum hash rate of a single chip can reach 74GH/S.

The Antminer S9 series has been in existence since 2016. The first Antminer S9 started with a hash rate of 11.852. Different models of S9 with different hash rates have been iterated continuously, and 13T and 14T versions have also been launched. In May 2018, Bitmain continued to launch upgraded versions of S9 with models S9i and S9j. The hash rate ranged from 13T-14.5T, and the power consumption was further reduced. In the winter of 2018, the market was also in the cold winter season. Bitmain also developed a water-cooled S9 Hydro bitcoin miner with a hash rate of 18T and power consumption of 1800W.
After many winters and summers, Antminer S9 still occupies a dominant position in the Bitcoin mining industry. Today, we evaluate the latest Antminers S9K and S9SE of Bitmain's Antminer S9 series.
Antminers S9K 14T and S9SE 16T were launched in July 2019. The Bitcoin market just experienced a small peak at that time, and the price reached $1,413.83. So perhaps this miner was born for this wave of the market.
Antminer S9SE-16T and S9K-14T are shorter and smaller than the first-generation S9. The physical size of Antminer S9K 14T and S9SE 16T is 321.3*129.6*200mm, and the weight is 4.56kg.

The number of power plugs of the three models of S9 is the same. There are three 6-pin power plugs on each of the three hash boards of the miner, plus the power supply connector of the control board; each miner needs 10 6-pin power connectors. It's just that the new generation of miner plugs has been replaced with more high-temperature-resistant materials.

Antminer S9SE 16T is the latest generation of S9 from Bitmain. The difference from previous generations is that a protective cover is designed for the position of the control board and power interface. It can be removed by removing the middle screw at the back of the cover, convenient for installing the power cable.

Antminer S9 hash board Antminer S9 hash board power supply unit Voltage and ground value test of Antminer S9 power supply unit 12V voltage test Test method: adjust the Fluke 15B+ multimeter to the DC gear; the red test lead is placed on the positive pole of the power interface of the hash board, and the black test lead is placed on the negative pole of the power interface. PIC chip voltage test There is a white dot next to the PIC chip, which is 1st Pin. Test method : Adjust the Fluke 15B+ multimeter to the DC gear, measure whether the 1st Pin of the PIC chip has output, and the normal voltage is about 3.3V. If there is no 3.3V, please check the connection status of the hash board test line to see if the hash board is normal; if not, you need to re-program the PIC. MOS tube voltage test There is a black dot on the MOS tube, which is the 1st Pin (Figure 1). This is because the voltage of t

What is the Antminer BM1489 ASIC chip?

What is the Antminer BM1489 ASIC c hip? Antminer  BM1489 ASIC chip is an ASIC chip on the Bitmain Antminer L7 hash board for mining Litecoin and Dogecoin. In the integrated circuit industry, an ASIC is considered an integrated circuit designed for a specific purpose. The characteristic of ASIC is to design and manufacture special integrated circuits according to user requirements. The chips used for mining are called ASIC miner chips. Compared with general-purpose integrated circuits, ASICs have the advantages of smaller size, lower power consumption, improved reliability, improved performance, enhanced confidentiality, and reduced mass production costs. In terms of mining hash rate, ASICs are tens of thousands of times or higher than contemporary CPUs and GPUs, so ASIC chips on the market are also more popular than them. Image courtesy of ZEUS MINING For example, Bitmain Antminer L7 , which is currently sought after by the market, is a standard ASIC miner, and it is the best choice f

How to use Antminer BM1387 tin tool to replace damaged chips?

How to use Antminer BM1387 tin tool to replace damaged chips? In the repair work of the h ash board, the most common problem is to replace the ASIC chip, which  is the most easily damaged part of the h ash board. In this article, I will use A ntminer as an example to show my friends how to use Antminer BM1387  tin tools to replace damaged chips?  Although there are many chip models, most of the pin positions and sizes are the same. ASIC chips are usually small in size and the pins are arranged closely, which brings great difficulty to maintenance and replacement. Because when replacing a new ASIC chip, it is necessary to accurately apply solder paste on each tiny pin, then heat it to melt, and finally fix it on the h ash board. For how to solve this problem, after various attempts, we finally chose a convenient and efficient way: making professional tin tools (ASIC tin tools). Its principle is to fix the chip on the base, then use a special steel mesh to align the pins of the chip, and

How long is the life of a miner?

How long is the life of a miner? Participating in mining is one of the important ways to enter the blockchain industry and enjoy industry dividends. Moreover, mining is more stable and more suitable for large institutions and significant funds to enter the market than buying currency. Mining is a highly specialized thing. Therefore, many new miners will face many problems before entering the market, such as: What are the ways to participate in mining? How to select miners scientifically? Is it more cost-effective to buy new miners or to buy used miners? Today, we will solve a problem many new miners may encounter before entering the market: How long can the purchased miners dig coins? In other words, how long is the life span of miners? 1. The physical life of the miner The life span of a miner can be divided into the "physical life" and "economic life". The physical life of a miner refers to the time from the time the miner is put into use in a brand new state unti

How to check and repair the hash board resistance?

How to check and repair the hash board resistance? After some fixed resistors are open or their resistance increases, their surface will have apparent changes such as cracks, pins disconnect, or blackened color. At this time, we can use an intuitive check to confirm whether they are good or bad.  If the appearance of the suspected resistor is normal, you need to test it with a multimeter to determine whether it is normal. Measuring resistance with a multimeter is divided into two methods: in-circuit detection and non-in-circuit detection. In-circuit detection is to directly measure the resistance of the suspected resistance on the circuit board to determine whether it is consistent with the nominal value. Non-in-circuit measurement is to measure the resistance after removing the resistance from the circuit board or suspending a pin. 1. Detect fixed-resistance (1) First, write down the nominal value. If it is a color ring resistor, first find out its resistance value according to the co
