ASIK AntMiner T9 + is considered one of the most productive mining devices of the Chinese company Bitmain. The new version of Bitmain T9 went on sale on January 30, 2018, becoming a direct competitor to the S9 model. In fact, ASIK Antminer T9 is a budget version of the popular Antminer S9 in the past, this device has retained the palm in terms of the number of sales in its price category for more than two years. And this is not at all surprising, because ASIC chips with the BM1387 marking, made according to the 16 nm process technology, were on both the Bitmain S9 and T9 asics. Of course, the more expensive Antminer S9 had more chips to compute, but in terms of price to performance and energy efficiency, the T9 was unmatched. But alas, this is all in the past.
The equipment operates on the SHA-256 algorithm, which made it possible to mine Bitcoin and Bitcoin Cash coins with it. You can also mine other cryptocurrencies, in the current period for ASICs on SHA-256, the most profitable are the DGB and Peercoin cryptocoins. It is still not worth putting them off for a long time, it is better to exchange them for BTC or BCH. The greater the variety of digital assets in the wallet, the less chance of going broke. Cryptocurrencies are volatile and tomorrow the rating of the most profitable coins for mining may change. But since we are reviewing a specific mining machine, it is more important for us now to understand how profitable the purchase of T9 + will be in 2020. Let’s take a look at the configuration and use features and start by describing the model.
Description and characteristics
The main characteristics of ASIK T9 + turned out to be quite decent. The performance of the model at 10.5 TX / s is provided by 162 BM1387 chips made according to the 16 nm process technology and located on three separate boards. The device is powered by a powerful 1.4 kWh power supply and takes up less space than a compact microATX computer system unit.
In the upper part of the aluminum body of the ASIC miner there is a control board with a connector for connecting an Ethernet cable, through which the equipment is connected to the Internet. There are also LEDs showing the operating modes of the device. On the upper edge of the block, you can see the connectors for connecting the miner to the power supply.
The inside of the Bitmain ANTminer T9 + is cooled by 2 coolers located at the front and back of the case. The fan speed is up to 6000 r / s and up to 4300 r / s, respectively. The noise isolation of the device is quite effective, but, taking into account the power of the miner and the operation of the cooling system, the level of generated noise reaches 75 dBA.
Tab. 1. The main parameters of the model.
| Characteristic | Value |
|---|---|
| Device hash rate, TH / s | 10.5 (from 10 to 12, depending on the pool and coin) |
| Mining algorithm used | SHA-256 |
| Chips and process technology | 162 pcs. BM1387, 16 nm |
| Electricity consumption, W | 1406-1419 |
| Noise level, dBA | up to 75 |
| Temperature (working, maximum) | 40 (81) |
| Case dimensions, cm | 32х12,5х19 |
| Weight, g | 6500 |
Thanks to the ANTminer T9’s speed of 10.5 TH s, the model was considered competitive enough for 2019. In 2020, the capabilities of the miner have significantly decreased. Custom firmware allows you to overclock this miner up to 16 Th / s… But given that the S17 can accelerate to 75 Th / s, with a consumption of 3000W, and the new S19Pro, in general, up to 110 Th / s (consuming not much more), mining on the T9 is profitable only if you got it very cheaply and you Pay nothing for electricity.
Official Stores
At the very beginning of sales, ASIK was available on the official website of the manufacturer and in several Russian stores. The cost of the model abroad was 41,958, in Russia – about 200,000 rubles. The decline in cryptocurrency rates and the increase in the complexity of their production led to a decrease in the price of the miner. Now it can be purchased ten times cheaper.
On the site https://ibmm.ru/, offering official Bitmain products, the price is not specified and is communicated personally to the client on a specific request. On https://www.avito.ru you can buy ANTminer T9 in Moscow for only 8000 rubles, or even for 6000 rubles.
Step-by-step guide to set up and connect
It is worth connecting and configuring equipment using an operating system specially designed for mining. When using Hive OS, T9 is configured in the same way as other Bitmain models:
- The ANTminer T9 is connected to the power supply and the Internet.
- The device is connected to the mains and starts up.
- The IP address of the equipment is determined using a browser.
- A suitable pool is selected to be used for mining.
- After registering on the service, a worker is created and the transition to the ANTminer T9 settings is performed.
- For each miner board, data is entered that correspond to the parameters of the pool. You can find them out on the FAQ or HELP tabs of the selected service.
- Settings are saved.
- The hardware is restarted.
If all actions were performed correctly, the technique automatically starts mining cryptocurrency. If errors were made during the Bitmain T9 + setup, the miner should be restarted again.
If you have any other problems, you should contact the technical support of the manufacturer or pool, as well as get acquainted with the information on thematic forums.
Overclocking and flashing the device
To increase the functionality of the device, company representatives recommend updating the ANTminer T9 firmware by downloading the latest software version on the manufacturer’s website. After flashing, the technique works more stable, although there is no increase in the hash rate.
You can increase the efficiency of the device by overclocking it. Increasing the number of fan revolutions and the frequency of the chips allows you to increase the mining speed from 10.5 to 16 TX / s. In this case, the increase in productivity is accompanied by an increase in the noise level from 75 to 80 dBA and an increase in the maximum operating temperature. Overclocked equipment works faster, but its service life is reduced.
To learn how to flash T9 + with custom software from MSKminer, which will allow you to overclock ASIK up to 16.5 Th / s, follow the link https://youtu.be/5pfReGHaQc8 and watch a detailed video tutorial. You can download custom firmware from MSKminer on the website https://www.soleniy.com/proshivki-dlya-asikov.
Please note that you perform all actions at your own peril and risk. No one except you is responsible for the breakdown of the device due to an unsuccessful flashing.
Good and bad qualities
The advantages of the T9 + model include the following characteristics of an ASIC miner:
- affordable cost, especially if you buy ASIK T9 bu (although the resource of the model will be lower);
- high performance;
- the ability to work with one of the most popular algorithms;
- high reliability – although repairing the ANTminer T9, if its chips fail, is almost impossible.
Among the disadvantages of technology, high energy consumption is noted – with round-the-clock operation, it will significantly increase the cost of paying for utilities. The owners of the T9 miner note the noise they create even without overclocking – the overclocked version makes even more noise. Therefore, it is worth installing an ASIC in a separate or at least non-residential premises.
Payback calculation: profitability 2020
To determine whether it is worth buying a device in 2020, the calculation of the average revenue from the extraction of cryptocurrency will help. To do this, you can use the popular calculator service. WhatToMine… Here you can enter the following information:
- 1400 watts of power consumption;
- 16500 Gh / s hash rate (let’s say that the custom firmware is successful and everything works);
- Important! Electricity was not included in the profitability calculation.
The calculation for the ASIC ANTminer T9 by the WhatToMine calculator shows that it is still profitable to mine a number of popular coins with the help of the miner. There is no Bitcoin among them. The maximum daily profitability for the ANTminer T9 model of 1.71 US dollars of net profit is provided when mining the DGB-SHA (DGB) cryptocurrency.
When calculating the payback period for equipment, take into account the cost of electricity in your region.At the moment, buying this equipment is unprofitable, since the profitability at an outlet price of $ 0.05 / kWh is only $ 0.03 per day. Of course, when digital gold rises in value, all costs will pay off. In the meantime, you will need to buy ASIK, find where to place it and pay for electricity costs from your own funds, without spending cryptocurrency. But why, if there are many more profitable mining machines on the market. We recommend buying newer models from the same manufacturer. Best to pre-order Bitmain Antminer S19 Pro… Happy mining!
