Antminer Z9 Mini: Specs | Hashrate | Profitability | Set-Up | Pros & Cons| Ethereum and Zcash (2020 & 2021) – The first devices on integrated circuits were created to mine Bitcoin for other coins using the SHA-256 algorithm.
The possibilities of these industrial mining monsters scared the cryptocurrency development teams so much that many blockchain networks began to take active measures to protect against ASICs. The fears were fully justified, the threat of a 51% attack hung over all crypto coins. And by and large, the only obstacle to its implementation for the same Bitcoin is the price of the issue.
The Zerocoin Electric Coin Company, the creators of the Zcash payment system, also once claimed the absolute “asic resistance” of their cryptocurrency. But alas, the music did not last long. One of the leaders in the production of mining machines, the Bimain company launched the asic bitmain antminer z9 mini and bitmain antminer z9, running on the Equihash algorithm.
A powerful and energy efficient miner with high profitability – asic bitmain antminer z9 mini aroused great interest among crypto-miners, the first batch was sold out instantly.
The next turn was the release of the full-size model bitmain antminer z9, and the manufacturer did not keep itself waiting long.

On antminer Z9 and z9 mini devices, the manufacturer soon blocked the overclocking option. But, when using modified software, the asic bitmain antminer z9 mini model overclocks to 16 ksol / s, and the antminer z9 – 58ksol. You can download the modified firmware for asic bitmain antminer z9 mini on the forum bits.media, in the “Hardware” section. Firmware available for both bitmain antminer z9 / z9 mini models on forum pages Bitcointalk (user efudd).
When overclocking the equipment, you should control the temperature of the hash cards and calculate the amount of energy consumed in accordance with the power of the power supply unit.
At the time of this writing, it is impossible to buy antminer z9 mini at retail on the official manufacturer’s website. On the territory of the Russian Federation, you can purchase antminer z9 mini in the Bitmain online store, IBMM at a price of 40,000 rubles. On the Alli-Express website, you can buy antminer z9 mini for 16 395.67 rubles. (without power supply).
Upon receipt of the order, carefully inspect the packaging and the device itself. Before connecting the asic z9, turn it over several times to check if there are any loose cooling radiators. If everything is in order, you can proceed to the second stage.
On the antminer z9 device, the mining setting does not differ from other bitmain models. If you are using a static IP address, you need to register it in the miner control panel. Static IP, in order to connect asic z9 is optional, for one or two miners.
The next stage of launching antminer z9 is setting up the pool.
The factory default antminer z9 uses Antpool. You can use other pools. The yang007 value is a sub-account, the numbers on the back differentiate your miner.
To install modified firmware from the Bitcointalk forum:
Instructions on how to overclock the asik z9 to 62 ksol.
It is best to tweak antminer z9 overclocking settings with fans set to 100%. When finished, adjust the speed of the fans to your liking, and check the stability of the output. Keep in mind that sometimes at a lower frequency, the device will show a higher and more stable hashrate. And do not forget, you use all modified firmware at your own peril and risk.
To change the pool, just specify other values for Pool 1. We take the settings on the selected service in the “Help” section. If you are a beginner and do not know what to mine on asic z9, please login to miningpoolstats.
This service provides a list of all Equihash coin pools that asic z9 mines.
Initially, the asic bitmain antminer z9 mini / z9 models were created specifically for mining Zcash, other altcoins were not so profitable. The online mining profit calculator will help you find the most profitable coin at the moment.
The main advantages of the asic bitmain antminer z9 mini / z9 are
The main disadvantage of the device is noise. This is a problem with all IC devices. The antminer z9 has the same decibel level of noise as a production facility or a crowded office.
And it far exceeds the limit noise levels established by law in apartment buildings.
Will help to calculate the profitability of antminer z9 calculator WhatToMine… We find the device in the list of supported miners and look at the asic z9, what is profitable to mine. At the time of this writing, the WhatToMine calculator calculated the profitability for antminer z9 as follows.
To calculate the profitability for antminer z9 mini for today:
Miners who bought the asic bitmain antminer z9 mini appreciated the efficiency and comparative low noise of this device. The model requires increased noise insulation measures, and is intended primarily for large players in the crypto-mining industry. However, if you live in a private house and can accommodate your miners in a room isolated from housing, then you can purchase a full-size version.
However, Bitmain has already released antminer z11, surpassing the ninth model in all respects. For the price, of course, too. But more about that sometime next time. Happy mining Lord prospectors.
