Ant Dash Miner D3 Review

Dash was created in 2014. Compared with Bitcoin, it has higher anonymity and faster transaction speed. The Dash team has made many technical upgrades this year and actively cooperated with other companies to promote the application of Dash. The efforts of the Dash team have caused the price of Dash to soar from a few dollars at the beginning of this year to the current 300 dollars.
Bitmain, a professional mining machine manufacturer, officially launched the Dash mining machine D3 in August this year. This is a new ASIC mining machine launched by Bitmain for a single encrypted digital currency after the Bitcoin and Litecoin mining machine series. The editor got a D3 these two days and conducted a comprehensive evaluation of it. Next, let's take a look at the performance of D3!
Basic product data

Unboxing photos <br/>Antminer D3 is packaged in a five-layer industrial carton. The outer box has logistics warehousing graphic labels, product barcodes, and the Antminer D3 logo. The editor got the 19.3G version this time.

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

Appearance and workmanship <br/>Antminer D3 adopts a dual-fan, three-computing board mining machine design. The body is one-piece formed, using precision die-casting design and aluminum alloy materials. In addition to providing strong protection for the computing chip, it also improves the overall heat dissipation efficiency of the body.

From the top of the mining machine, you can see that the D3 is composed of three hash boards. Each hash board has three PCI-E6pin interfaces and three data cables connecting the hash board to the controller.

From the front of the mining machine, you can see the IP address feedback button, network cable interface, reset button and status indicator light (as well as the Antminer D3 logo and qc label). A 12cm diameter fan can be seen on the front, and air enters from this side.

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

D3 uses Bitmain's self-developed chips, and there are 60 chips on each hashboard. Bitmain equipped D3's chips with independent heat sinks, continuing the practice of the Antminer series at all costs. The overall structure of the mining machine is very tight, and the extended intervals of the heat dissipation modules bring a larger heat dissipation area. The intervals also form a unique air duct inside the mining machine, which can maximize the use of fans and structural cavities to push the heat dissipation effect to the extreme.
Installation and debugging <br/>The power supply used in this test is Ant Power APW3+, and the mining pool uses Ant Mining Pool under Bitmain. The installation and wiring method is the same as S9 and L3+. Connect according to the official video tutorial of Ant Miner. https://v.qq.com/x/page/l0560u1kh9z.html
Heat and noise <br/>The Antminer was used in PPLNS mode for mining. The test location was a conference room with an area of ​​approximately 30 square meters and a room temperature of 28 degrees. Heat and noise tests were carried out after the mining machine had been running for 24 hours.
The noise level of the Antminer D3 was 88dB at 10cm away from the air outlet, but it dropped to 70dB at 1m away. After closing the door, there was no obvious noise.

After running for 24 hours, you can see in the background of the mining machine that the temperature of the D3 hashboard is 64 degrees and the temperature of the chip is 84 degrees. These temperatures are within the normal range.

Computing power and power consumption

Antminer D3 hourly computing power curve The official computing power of the Antminer D3-19.3G version is 19.3G. In actual tests, the actual computing power average is around 19.41GH/s, which is higher than the nominal value. The power of the Antminer D3-19.3G version in actual tests is 1278W, and the power consumption per G computing power is 65.8W/G.
As of the press date (October 24, 2017), the price of Dash is 1940 yuan. According to the Ant Pool PPLNS profit model, the profit of a D3 in 24 hours is 0.067 DASH, which is equivalent to 130 yuan. Calculated at 0.3 yuan per kWh, the daily electricity fee of D3 is 9.2 yuan, and the daily profit is about 120 yuan.

Antminer D3 power
Overclocking test <br/>The default operating frequency of Antminer D3 is 537M. Set the frequency of the mining machine to 650M and overclock it. After running for a period of time, the computing power of D3 increases to about 22.7G. At this time, the temperatures of the computing board and chip are higher than the default state. The temperature of the computing board is 74 degrees, the temperature of the chip is 97 degrees, and the power rises to 1589W. Under overclocking, the power consumption per unit computing power is 70W/G, which is slightly higher than the default operating frequency. Long-term overclocking is not recommended.

Summary <br/>The overall performance of the Antminer D3 is surprising. The power consumption per unit of computing power is as low as 65.8W/G. The computing power remains stable after long-term operation. The D3 also demonstrates excellent strength in overclocking.

Antminer D3 continues Bitmain's precision quality. The product runs stably without any failures and is very easy to install. The actual computing power will be higher than the nominal computing power during operation. D3 does not make much noise. There is basically no noise after closing the door. It can also be used in residential houses. Dash has great potential for future development. Using Antminer D3 to mine Dash is a very good choice.
