The crypto winter has its positive aspects. The long stagnation in the market forced the manufacturers of mining devices to seriously work on the energy efficiency of their products.
The result of hard work was the emergence of new, most economical models. For example, Bitmain has released a low-cost SHA-256 mining machine. Bitmain antminer S11 device, assembled on 16 nm chips, but similar in characteristics to antminer T15. At the same time, it is cheaper, which increases its competitiveness in the cryptocurrency miners market.
The bitmain antminer S11 model, made in a two-story version, comes complete with a power supply and, according to the manufacturer’s statement, is sold in an official store in batches of 1 to 10 pieces per hand. At the time of this writing, all the bitmain antminer S11 miners on the official website have been sold.

This means that budget ASICs are in demand even during the downturn in the cryptocurrency market. Let’s take a closer look at the ASIC s11 device characteristics and features of the model.
| Model | Antminer s11 |
|---|---|
| Hashrate, (maximum performance) | 20.50 TH/s |
| Hashrate, (power saving mode) | 16/17.50 TH/s |
| Maximum power consumption in high performance Watt mode | 1435 Watt |
| Maximum power consumption In economy mode | 1024 Watt |
| Energy efficiency in maximum performance mode | 74.5 J/TH |
| Energy efficiency (In economy mode) | 67.5 J/TH |
| Number of hash chips | 252 |
| Number of hash boards | 3 |
| Network connection | RJ45 Ethernet10 / 100M |
| Dimensions (edit) | 238/175 / 278mm |
| The weight | 8.1 kg |
| Noise level | 76 dB |
As you can see from the table taken on the official website of the manufacturer, the dimensions, weight and consumption of bitmain antminer S11 almost do not differ from S15 and T15… The operating temperature of the mining machine is 40 C, the hash rate at maximum overclocking can be increased to 20.95 TH / s, and on alternative software, up to 23.95 TH / s. Some experts advise against experimenting with overclocking ASIKs “in the air”, but placing the devices in a container with immersion liquid.
Where to buy and how much does it cost
You can buy a device for mining antminer s11 bitcoin in Moscow from an official dealer of Bitmain, on the website https://ibmm.ru/katalog/bitmain/antminer-s11, for 18,500 rubles, delivery to all regions of the Russian Federation is possible.
On aliexpress.com, the price for new antminer s11 miners starts at 19,000 rubles, shipping to the buyer is free.
Connection and setup, step-by-step guide
As stated in the bitmain antminer S11 operating manual, all devices are pre-tested and configured to ensure the most comfortable conditions for the user to start the drilling rig. And yet, carefully inspect the new manner, flip it over several times to check for any loose cooling heatsinks.
Antminer S11 connection begins with the server configuration. Procedure.
1.Go to: https://shop.bitmain.com/support and download IPReporter.zip
2.Unzip the application and run as administrator.
3.Choose one of the work options:
- Shelf, Step, Position – suitable for a farm of several miners in industrial mining.
- Default – suitable for a home miner.
4.On the controller board, press the IP Report button. Hold until you hear a beep (about 5 seconds). The IP address will be displayed in a window on the computer screen.
6.In your browser, enter the provided IP address.
7. Go to your control panel to configure antminer S11 using “root” as username and password.
8.In the Network section, you can assign the DHCP IP address.
9.Click the “Save and Apply” button.
Now you need to connect antminer S11 to the pool.
Open General Settings.
1.Set connection parameters
- Pool URL – 3 pools can be registered in the antminer S11 settings. Server # 1 will be used by default. If the connection to it is lost, the miner will automatically switch to the next pool in the list.
- Worker — ID on the selected pool.
- Password — your miner’s password
2.Click Save & Apply and restart the miner.
To check the working status of your device, go to Miner Status… The working parameters of the miner can be adjusted automatically. The miner stops working if the hash board temperature reaches 95 C.
Information is available on the control panel
- ASIC # – the number of chips in the chain.
- Frequency – operating frequency.
- GH / S (РТ) – hash rate of each of the boards.
- Temp (PCB) – board temperature.
- Temp (Chip) —heat the chips on each board.
- ASIC status:
- Oh – everything is fine
- X – miner is not working correctly
- – – the miner is offline, or out of order.
You can connect antminer S11 to p2pool, this is a very promising Bitcoin mining pool. As for Hive OS, ASIK bitmain antminer S11 is not included in the list of supported devices and, unfortunately, we could not find data on usage in the hive.
And so the pool is running, the miner status is “O”, which means that the antminer S11 setup is complete.
Overclocking and flashing the device
To check the firmware version, go to the Overview tab. The File System Version column displays the version of the current firmware. If the manufacturer’s website has a new version of the firmware for antminer s11, you can proceed to the update.
Attention! If, during the flashing process, power is cut off, or contact with the server is lost, the miner will have to be sent for repair.
To start the upgrade, go to Upgrade.
- Check the box to save the current settings (default), or uncheck if you want to change the miner settings.
- Click Browse (the button is in Chinese) and navigate to the update file. Select the update file, then click Flash image. A notification message will appear if the antminer S11 firmware can be updated and the green light will flash.
- To install unofficial firmware on antminer S11 device:
- write the firmware to the SD card;
- insert the SD card into the miner slot;
- select Upload archive, upload from removable media;
- click Flash image.
After the completion of the antminer S11 firmware, the following message will appear.
You will be prompted:
- Reboot – reboot to start the miner with new software.
- Go Back – continue working with the current version.
Overclocking antminer S11 is carried out by increasing the operating frequency. The manufacturer has installed overclocking protection in the standard firmware; with an increase in frequency, the power of the power supply decreases. Alternatively, you can use an unofficial firmware by downloading it on one of the Internet resources, for example, MSKMINER. But keep in mind, you do all the manipulations at your own peril and risk.
Repair of antminer S11 in case of a fiasco with alternative software, you will have to pay out of your own pocket. In Moscow, warranty and post-warranty repairs of antminer S11 and other ASIKs are performed by a service center BitSouls.
Positive and negative qualities of S11
The advantages of the S11 are its price and the ability to operate in an economical mode. This option will be the most optimal in regions with expensive electricity. Asik S11 used, taking into account the recent appearance of this model on the market, is not found on sale as often as s9. And buying a used ASIC S11, like any other model, is not a good idea.
The disadvantage of the S11 miner is noise, in full overclocking it makes much louder noise than the antminer S9. By and large, ASICs are devices for industrial mining, if you want to purchase the S11 noise miner, it will be the main argument against such a purchase. However, this problem applies not only to this model.
Payback calculation
Terms of return invested in a purchase ASIC money will help to calculate the mining profitability calculator. First of all, for antminer S11, the daily profit depends on the bitcoin rate and the cost of electricity. We go to the corresponding tab of the WhatToMine calculator, enter the price of one kilowatt in dollar terms and the service will display the profitability indicator of antminer S11 per day, at the current BTC rate.
There are not so many reviews of antminer S11. Bitmain cares about the reputation of the brand and produces quality products that can safely serve at least the manufacturer’s stated warranty period. So there will be positive reviews for this model soon. The device is inexpensive and given the high potential of bitcoin, you should think about purchasing it.
By the way, recently a new optimistic forecast of the bitcoin rate flashed on the network in just two or three years – $ 400,000. Of course, this is just someone’s assessment of the prospects of the cryptocurrency, but who knows, suddenly these numbers will become reality.
