Basic Data

Package 

Antminer D3 is packed in five layers of industrial cartons, with logistics and storage graphic marks, commodity bar codes and the logo of Antminer D3. Xiaobian got version 19.3g this time.

The packaging protective layer of the mining machine adopts pearl cotton board, which effectively ensures the transportation safety and prevents collision during transportation. In addition to the miner, an English manual of the miner is attached in the box.

Appearance and Workmanship

Antminer D3 adopts the design of double fans and three calculation force plate miner. The body is formed as a whole. It adopts precision die-casting design and aluminum alloy materials to provide strong protection for the computing chip and improve the overall heat dissipation efficiency of the body.

From the top of the mining machine, it can be seen that D3 is composed of three force calculation boards. Each force calculation board has three pci-e6pin interfaces and three data lines connecting the controller from the force calculation board.

From the front of the miner, you can see the configuration of IP address feedback button, network cable interface, reset button and status indicator (as well as Antminer D3logo and QC label). A fan with a diameter of 12cm can be seen on the front, from which the air enters.

From the back of the mining machine, you can see the cooling fan of the mining machine, and the air comes out from this side.

D3 adopts bit continental self-developed chips, and there are 60 chips on each computing board. Bitland provides D3 chip with heat sink independently, continuing the practice of Antminer series at all costs. The overall internal structure of the mining machine is very tight. The interval extension of the heat dissipation module brings a larger heat dissipation area. At the same time, the interval also forms a unique air duct inside the mining machine, which can maximize the use of the fan and structural cavity to push the heat dissipation effect to the extreme.

Installation And Commissioning

The power supply for this test uses the ant power supply apw3+, and the mine pool uses the ant mine pool under bit continent. The installation and wiring method is the same as that of S9 and L3+, and the connection is carried out according to the official video tutorial of Antminer. https://v.qq.com/x/page/l0560u1kh9z.html

Heat And Noise

The Antminer PPLNs mode is adopted for mining. The test site is a meeting room with an area of about 30 square meters and the room temperature is 28 degrees. The heating and noise test is carried out after the miner operates for 24 hours.

10cm away from the outlet of Antminer D3, the measured miner noise is 88DB, but the noise drops to 70dB more than 1m away. After closing the door, there was no obvious sound.

After 24 hours of operation, it can be seen in the background of the mining machine that the temperature of the D3 force calculation board is 64 degrees and the temperature of the chip is 84 degrees. These temperatures are in the normal range.

Computing Power And Power Consumption

Hourly force calculation curve of Antminer D3

Antminer D3 power consumption

The official standard computing power of Antminer D3-19.3g is 19.3g. In the actual test, the average value of the actual computing power is about 19.41gh/s, which is higher than the nominal value. The actual test power of Antminer D3-19.3g is 1278w, and the power consumption per g is 65.8w/g.

On October 24, 2017, the price of dascoin was 1940 yuan. According to the income model of ant mine PPLNs, the income of one D3 24 hours a day was 0.067dash, equivalent to 130 yuan. According to the calculation of 0.3 yuan per kilowatt hour, the daily electricity charge of D3 is 9.2 yuan, and the daily income is about 120 yuan.

Summary

The overall performance of ant miner D3 is amazing. The power consumption per unit computing power is as low as 65.8w/g. The computing power remains stable under long-time operation. D3 also shows good strength on overclocking. Antminer D3 continues the Seiko quality of bit continent. The product runs stably without failure and is very convenient to install. In actual operation, the calculation force will be higher than the nominal calculation force. D3 is not noisy. After closing the door, there is basically no noise. Civil houses can also be used. Dascoin has great development potential in the future. Using ant miner D3 to dig dascoin is a good choice.
