On February 27, 2020, Bitcoin Antminer S19 series was announced by Bitmain, the latest bitcoin miner S19 series is announced in 2 models: Antminer S19 Pro 110T and Antminer S19 95T, the S19 Pro has a single machine power of 110TH/s and energy efficiency ratio as low as 29.5J/TH.

The two new models went on sale online on March 23 at the Bitmain online official. The first sale will be shipped during 2020.05.11-2020.05.20, both models are currently sold out.

As we all know, Bitmaincoin's ant miners with the letter "Pro" are all top-of-the-line flagship miners with excellent performance, stable and reliable operation, and playability (adjustable voltage regulation) is also not to be underestimated.

Antminer S19 Pro 110T Unpacking

This time, we received the S19 Pro 110T engineering prototype. The industrial carton packaging is simple, no logo. Just arrived at the feeling is that the Antminer machine has become bigger and heavier. From the volume and weight can directly feel the change of the new mining machine. Logistics packaging size: 680x425x535, the whole weight 15.3kg, compared with the previous series can be described as "higher and stronger".



The mining machine inside the box covered by the pearl foam cotton using the form of button cover for protection. There is also a layer of anti-static bag package.



First of all, look at the appearance of the whole machine with integrated power supply, all-in-one machine design, front and rear parallel dual fan exhaust air cooling, dual 10A power supply interface. Machine can be placed up or lying down. The machine is 370x195.5x290mm and 13.2kg in weight.







Antminer S19 Pro 110T Infrastructure

Our analysis of the mining machine is mainly to dismantle the three main components of the mining machine (control board, mining board and power supply), and then do some comparative analysis of the auxiliary parts (housing, heat sink, fan, connection wires, etc.).

Control Board

Remove the air side control panel cover screw and push the button up to open the control panel cover.



To facilitate the next step, remove the protective cover that connects the power supply to the copper plate next to it (the two screws of the protective cover also hold the power supply cover in place), and you can see the power supply and voltage regulation cables of the control board.



The first thing to see is the connecting copper row of the power supply and the arithmetic board, the ant S19 Pro 110T is different from the ant S17+ 76T, no longer cross walk, the positive copper row is marked with the symbol " + ", the more significant difference is the increased thickness of the copper row.



Another notable feature is the lengthening of the cable that connects to the power board, which means that the power board is longer than its predecessor, and next to the cable are four 4-core cooling fan ports and the control board power supply port.



Remove the baffle in front of the control panel and the connecting wires on the control panel to pull the control panel out of the inlet side.



The Antminer S19 Pro 110T uses a redesigned control board with the PCB color changed to blue, while the size and interface remain the same as the 17+.





Control board interface description: SD card slot, used for firmware upgrading; IP Report, used with the ant tool to find the IP address of the mining machine; LAN socket; Reset/restart button (long press to restore the factory settings); LED indicator - display the mining machine operation status.

Power Supply

Remove the air side power supply retaining screw, and push back, then remove the entire power supply. The Antminer S19 Pro 110T is paired with a new, up to conversion rate 95% APW12 power supply that offers 12-15V adjustable voltage, a nominal maximum load of 3600W, and a limit load of up to 4000W.





This new APW12 power supply also uses two 10A power cords for power supply. Dual input can reduce the safety risk of input cord socket heating and so on. The entire power supply is larger than the previous series, the cooling channel is larger, three fans are used to provide active cooling for the power supply, the fan size is updated from the S17 series 40mm fan to 60mm, the benefit is that the fan speed is reduced and the power failure rate is also reduced.



Mining board

The Antminer S19 Pro 110T uses a deep, custom-optimized cooling design that uses only four 1.65A fans to provide heat dissipation for the power plate.





The Antminer S19 Pro 110T uses a new mold for its housing, instead of using the S17+ split combination. It goes back to a one-piece molded die-casting, with the power supply, control board, and arithmetic board slots designed to be in place in one step, with a flat bottom when laying flat and no seesaws, and the finished product is not expected to be shipped with a rubber pad.







The Antminer S19 Pro 110T comes with 3 built-in mining boards, which are more square and simple, with heat sinks affixed on both sides, and a deep, custom-optimized thermal design that is more visible.





The chip surface uses 2 whole pieces of heat sink to dissipate heat, the whole piece of heat sink is designed to flow linearly, air resistance is less convenient for air circulation, can quickly bring out the heat and effectively reduce dust accumulation, the heat sink and chip contact surface uses pink heat transfer gel filling and fixed with screws.





On the other side, a single heat sink is used to dissipate heat, the area of the heat sink gradually increases from the air inlet side to the back, effectively ensuring that the whole arithmetic plate evenly dissipates heat.



The Antminer S19 Pro 110T is equipped with a new generation of TSMC 7nm custom chip, the chip model is BM1398. 114 chips in each mining board, a total of 342 chips provide 110T computing power, and each chip provides nearly 322G computing power. Imagine the first generation of ant mining machine ant S1's computing power is only 180G, this ant S19 Pro 110T a chip is already nearly 2 Antminer S1, it is really the Yangtze River after the wave pushing forward, a generation is stronger than a generation...

This is the end of the internal analysis of the Antminer S19 Pro 110T and the last family photo.





Antminer S19 Pro 110T Software Configuration

Start the Antminer S19 Pro 110T by connecting the two prepared 10A power and network cables to the miner. Wait for the miner light to go off, enter the router or use the APMinerTool iwith the miner's IP report button or use the BTC.com Mining Pool Batch Tool to scan the LAN to find the IP address.

Enter the found IP address into the browser address field, then enter the login username and password (both default "root") to enter the mine control page.

The first step of mining: configure the mining pool, click "Mine Machine Configuration" to enter the mine pool setting page. In this page you can set 1 main mining pool and 2 backup mining pool, you can set the fan speed to fixed mode. You can set the mine machine working mode to "normal" or abnormal mode (sleep), let the mine machine sleep is definitely abnormal mode. After setting up, remember to click on "Save". And the latest firmware has a feature that allows you to switch pool miners in the middle of a run without changing the hardware configuration, saving you the trouble and efficiency.

The next step is to modify the IP address of the miner as needed.

The new interface shows the machine model number, algorithm, arithmetic curve, running time, mining pool information, hardware/firmware version, reset button, restart button and all the useful information in one interface. The arithmetic curve can keep the arithmetic running curve of the mine machine in the past 6 hours, which is convenient for miners to observe the operation of the mine machine at any time. It is more than a more humanized mining experience, it is simply a mining enjoyment...

Antminer S19 Pro 110T Actual Test Data

The firmware of the Antminer S19 Pro 110T is a new design. The mining machine is fast to start. The process of self-testing frequence is optimized, and the mine starts immediately (about two minutes). After setting up the mine pool, testing the Antminer S19 Pro 110T for more than 24 hours, the following data is obtained.

The inlet temperature (room temperature) is 25 degrees, the inlet humidity is 64%, the outlet temperature is 35.2 degrees; the outlet humidity is 40%; the power outlet temperature is 31.8 degrees; the temperature between the power supply and the mine is 26.6 degrees. The Ant S19 Pro 110T consumes 3229W overall.
