Antminer Z9mini Latest Review

Antminer Z9mini is a new mining machine launched by Bitmain in May. After the launch of this mining machine, the Antminer family has added another member. Z9mini mining machine can support Equihash algorithm encrypted digital currency, and currently can mine encrypted currencies such as ZEC. Antminer now has multiple product lines such as S series, L series, D series, and Z series. So today we will take a look at the performance of this mini version of Z9mini mining machine.

Z9mini basic parameters

Like other miners in the Antminer family, the Antminer Z9mini is packaged in a five-layer industrial carton. However, because the miner is a mini version, the overall packaging is more than half smaller than that of ordinary miners. The outer box has a logistics warehousing graphic representation, a product barcode, and the logo of the Antminer Z9mini. The packaging protective layer of the miner is made of pearl cotton board, which can effectively ensure the transportation safety of the miner and reduce collisions during transportation. In addition to the miner, the box also comes with a Chinese and English manual for the miner.

Z9mini appearance and workmanship

The Antminer Z9mini adopts a single-fan, three-computing-board mining machine design. The body is one-piece formed, using precision die-casting design and aluminum alloy materials. This design not only provides strong protection for the computing chip, but also improves the overall heat dissipation efficiency of the mining machine body.

From the top of the mining machine, you can see that the Z9mini is composed of three hashboards. Each hashboard has a PCI-E6pin interface. Each PCIE interface needs to be connected to a power supply. The Z9mini control board has a PCIE interface, which is connected to a power cord. Next to it are three data cables connecting the hashboard to the control board.

On the front of the mining machine, we can see the IP address feedback button, network cable interface, reset button and status indicator light. The front fan of the mining machine is the air intake area; it is worth noting that the heat dissipation area of ​​Z9mini has removed the fan and uses a honeycomb-shaped heat sink, making the overall design more compact and smooth. The internal structure of Z9mini is very tight, and the extension of the heat dissipation module interval brings a larger heat dissipation area. The module interval also forms a unique air duct inside the mining machine, making the maximum use of the fan and structural wall to maximize the heat dissipation effect.

Z9mini installation and debugging

The power supply used in this test is Ant Power APW7 , and the mining pool used is Ant Mining Pool under Bitmain. The installation and debugging of Z9mini can be carried out according to the official video tutorial of Ant Miner. The link is as follows: https://mp.weixin.qq.com/s/mlBfrdRgMO7g4eRfAgd0SQ

Z9mini heat and noise

This time, the mining was conducted in the PPS mode of AntPool. The test location was a conference room with an area of ​​about 10 square meters and a room temperature of 27 degrees. After the mining machine was running for 24 hours, the heating and noise of the mining machine were tested.

At 10 cm away from the air outlet of the Antminer Z9mini, the noise detector measured the noise of the mining machine to be 65.5 dB . After closing the door of the conference room, the operation sound of the mining machine can hardly be heard. Relatively speaking, the noise of the Z9mini is still relatively low.

After running for about 24 hours, you can see in the background of the mining machine that the chip temperature of Z9mini is about 56 degrees , which is within the normal range.

Z9mini computing power and power consumption

The official hashrate of the Antminer Z9mini is 10k sol/s . You may wonder what this hashrate means. Actually, the unit sol/s is similar to h/s, indicating how many answers can be found per second. The answer refers to the term in the Equihash algorithm, which is essentially the same as how many HASH can be calculated per second.

In this test, we can see that the actual average hashrate of the Z9mini is around 10.97Sol/s , which is slightly higher than the nominal value. In terms of power consumption, the actual power of the Antminer Z9mini is 252.1 W , which is also lower than the nominal value.

Z9mini Summary

Although the Antminer Z9mini is slightly smaller than ordinary mining machines, the product quality still maintains the precision quality of the Antminer. The product runs stably and is very easy to install without any malfunctions. In the actual evaluation, the performance of the Antminer Z9mini is also quite impressive. Both the computing power and power consumption are better than the official standards. The noise performance is also good, and there is basically no noise after closing the door. In short, the Antminer Z9mini is a mining machine worth buying, and its compact appearance will definitely attract you!
