review, configuration and profitability of buying used devices

The first industrial mining devices were focused on bitcoin mining. But soon the developers turned their attention to other mining algorithms and immediately got a bunch of problems.

The bitmain antminer D3 model, created for mining the Dash cryptocurrency at the time of release, promised a profit of $ 120 per day. But the happy buyers did not even have time to return the money spent on ASIK, when the rapidly increasing complexity of mining turned the D3 miner into a useless toy. Nevertheless, bitmain antminer D3 is on sale to this day. And so, let’s talk about how the way out of this situation was found, as well as the technical characteristics of the Dash mining rig.

Antminer D3 specifications

The bitmain antminer D3 integrated circuit device is made in the form of a rectangular tube with two fans. The miner is small and lightweight and has a fairly moderate energy consumption. Let’s take a closer look at ASIC d3, characteristics and configuration settings.

In practice, the speed and power consumption of ASIK exceed the bench parameters. Even on the factory firmware, antminer D3 accelerates to 19-20 GH / s, while consuming 1200 W if the room temperature does not exceed 25 ° C.

Where to buy and how much does it cost

You can buy a machine for mining cryptocurrency using the X11 antminer D3 algorithm in Moscow in many outlets, but it is best to purchase it from a representative of Bitmain. Website address: https://ibmm.ru/, price 9850 р., there is a delivery service in the Russian Federation and the CIS. On the aliexpress website, antminer D3 with a power supply costs from 11 550 р.

Connection and setup, step-by-step guide

Bitmain miners must be inspected before shipment to the customer, both at the factory in China and at the point of sale of the regional dealer. Nevertheless, you need to double-check everything personally. Connecting and configuring antminer D3, like any other ASIK, should begin with a visual inspection and quality control of the assembly. To do this, it is enough to turn the product 2-3 times, if nothing has fallen off inside, we start connecting and setting up bitmain d3.

• Connect the power cables to the boards as shown in the picture.
• Download and run IPReporter.
• Select the default mode (default), if you have one miner, Shelf, Step, or Position is suitable for a farm of several devices.
• Press IP Report on the back panel and hold until you hear a beep.
• Copy the received IP and enter it in the address bar of your browser.
• Open antminer D3 settings management, default name and password— root.
• If you have a static address, write it in the Network tab.
• Click Save & Apply and go to the pool settings section.

Connecting antminer d3 to a mountain pool.

• Войдите в General Settings/Miner General Configuration
• Write down the first configuration of the priority pool (Pool URL), in total you can specify 3 mining addresses. The miner will automatically switch to the server lower in the list if the first one is not available.
• Specify the miner’s name in the Worker section
• In the next paragraph, specify the password for the device on the pool.
• Click Save & Apply and reboot.

You can adjust the operating frequency in the Configuration – Advanced Settings section, but take into account the breakdown of the miner during overclocking – not a warranty case. Repair of antminer D3, in case of an unsuccessful experiment, will have to be paid for by yourself.

The dashboard (Miner Status) shows:

• number of chips;
• operating frequency;
• hashrate of each board;
• temperature of hash boards and chips.

Normally working nodes of the miner have the status “O”. In case of incorrect operation “X”, and two dashes (-) denote a complete failure.

If you wish, you can work on this device with Hive OS, D3 is included in the list of supported ASIKs.

Overclocking and flashing the device

The preinstalled antminer d3 firmware is displayed in the Overview / File System Version section.

To update:

• go to Upgrade.
• Select the update archive and click Flash image, the green indicator should blink.

At the end of the antminer D3 firmware, you will see the Overview window, restart the miner to apply the updates.

To improve the productivity of your miner, you can install alternative software on him.

Write the firmware file to the SD card, insert the media into the miner control board connector and flash antminer d3 from the file on the storage device.

Attention! You install any unofficial firmware at your own peril and risk. Repairing antminer D3 in case of a breakdown during non-standard overclocking, or an update error, will be your problem. However, if your rig has been used for more than 6 months, then the warranty has already expired. Remember, too, that increased overclocking requires increased ventilation of the device and a low room temperature.

Positive and negative qualities of D3

Consider the pros and cons

The D3 miner cannot be operated in apartment buildings, the noise of its fans is higher than the legal norm for residential premises. However, this disadvantage applies to all devices based on integrated circuits.

Calculation of payback ASIC D3 profitability 2020

Online service whattomine will help you calculate the daily profitability for antminer D3. Go to the ASIC section, and enter in the X11 column, hashrate and power consumption asic antminer d3, the calculator will show all profitable coins.

However, the calculator calculated the daily profitability for the asic antminer d3 based on the factory parameters of the device. In addition, when the rate of cryptocurrencies stabilizes, all costs will pay off with interest.

When calculating the profitability, the cost of electricity was not taken into account, if calculated with the cost of light, the profitability is negative!

At one time, bitmain antminer D3 caused a storm in the cryptocurrency community. The reviews did not concern the quality of the device, in principle there were no complaints about it, but the situation with a sharp loss of profitability. Buyers were given $ 150 coupons to purchase goods on the Bitmain website as compensation. Then the Dash rate took off, and the situation returned to normal.

History clearly demonstrates the weaknesses of ASIKs:

• impossibility of rebuilding to another algorithm
• rapid loss of relevance.

As soon as a new model comes out, the old miner, like in the fairy tale of Charles Perot, turns from a golden carriage into a pumpkin.
