Technical specifications, the cost, pros and cons, the calculation of payback Z9 in 2019 and the customer reviews of device Antminer z9

The very first devices on integrated circuits were created for bitcoin mining of other coins on the SHA-256 algorithm.

The possibilities of these monsters of industrial mining frightened the team of cryptocurrency developers of so much that many blockchain networks began to take active measures to protect against ASICS. Fears were justified by the threat of attack 51% hungover all cryptomelane. In addition, the only obstacle to its implementation on the same Bitcoin is the price of the issue.

The company Zerocoin Electric Coin, the creators of the Zcash payment system, also once claimed the absolute stability of their own cryptocurrency. But it did not last long. One of the leaders in the mining industry, Bimain company released ASIC Bitmain Antminer Mini Z9 and Z9 Bitmain Antminer working on the Equihash Algorithm.

Technical parameters

Powerful and energy-efficient miner with a high return – ASIC Bitmain Antminer Z9 mini aroused great interest among CryptoStorage, the first batch sold out instantly.

Next was the release of a full-size model Bitmain Antminer Z9, and the manufacturer did not keep us waiting.

The manufacturer soon blocked the overclocking option On the Antminer Z9 and Z9 Mini devices. However, if you use the modified software, ASIC Bitmain Z9 mini model accelerates to 16 ksol/s and Antminer Z9 – to 58ksol. Modified firmware can be downloaded for ASIC Antminer Z9 mini in the "Hardware" section of the bits Firmware for both models is available on the Bitcointalk forum pages (efudd user).

When overclocking the equipment, the temperature of the hash boards should be controlled and the amount of energy consumed should be calculated in accordance with the power of the PSU.

Where to buy and how much it costs

At the time of writing, the Antminer z9 mini model is not available on the website of the official manufacturer. On the territory of the Russian Federation, you can buy Antminer z9 mini from an authorized Bitmain’s dealer, Antminer-Russia company for 29 000 rubles. On Ali-Express Antminer z9 is sold for 16 395,67 RUB.

This service is available to list all the pools for coins Equihash algorithm that produces ASIC z9.

What to mine, how to choose a profitable token

Initially, models ASIC Bitmain Antminer mini Z9 /Z9 were created for the extraction of Zcash for other altcoins that were not as profitable. Find the most profitable coin now will help the online calculator of mining profit.

Pros and cons, what you need to know about the Zcash algorithm

The main advantages of devices are:

  • Performance;
  • Energy consumption;
  • Compactness;
  • Easy to set up and run.

The main disadvantage of the device is noise. This is the problem of all devices on integrated circuits. The noise of Antminer z9, in terms of decibels, is the same as the noise in the workplace, or in a crowded office.

And it exceeds the statutory boundary noise levels in apartment buildings.

Customer reviews of Antminer z9

Miners who bought ASIC Bitmain Antminer Z9 mini appreciated the efficiency and comparatively 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 their miners in an isolated room from the housing, you can buy a full-size version.

However, Bitmain has already released Antminer z11, which is superior to the ninth model in all respects. The price is high, too. We will talk about it next time.
