[Mining Review] Jinbei HS5 Disassembly Test

With my heart trembling with excitement, I am going to disassemble the Jinbei HS5 today. Yes, it is the latest gold mining tool just launched by Jinbei Mining Machine, which has always been committed to bringing forth new products to shock the eyes of miners!

Compared with previous products, Jinbei HS5 has two highlights that deserve your attention:

First of all, the performance has increased significantly. The official website states that the HS5 has a computing power of up to 2700Gh/S, which seems to be a bit fierce. The editor once had the honor of doing a disassembly and evaluation of the Jinbei HS3-SE. Compared with the characteristics of HS3-SE, which is both internal and external, HS5 can be said to have spent all its efforts on internal cultivation. The image of HS5, which is low-key, can finally make miners believe that it is a HNS mining machine for profit, rather than a smart home appliance. (Of course, HS3-SE once had impressive returns, but its cool appearance exceeded everyone's imagination of mining machines).

Secondly, HS5 supports dual mining of HNS and SC. Old hands in the mining circle know that a machine that can mine dual means that you are 50% less likely to shut down than other ASIC miners. Jinbei fans must be familiar with HNS, so I won’t explain it here. I will just briefly introduce SC:

SC (Siacoin) is a relatively early cryptocurrency that is only used for the Sia cloud storage system. The total amount is 44.6 billion, and it is now fully circulated. The peak market value is 26 billion, and the lowest price is 0.000078 yuan and the highest is 0.77 yuan (unexpectedly, it is a veritable 10,000-fold coin). SC is listed on 23 exchanges, and 6 of the top 10 exchanges are listed, including Binance, Huobi, and OK. From the perspective of blockchain browsers, SC is still quite active, with a total of 960,000 addresses holding coins, 1,200 transactions in 24 hours, and a total of 13 million transactions.

Old miners love and hate SC. Some people jokingly call SC "the old immortal". In 2018, the peak price of SC once reached 7 cents. The current price is 6 cents, which is 11 times away from the peak. Recently, someone on Bihu predicted that the upward channel of SC has been opened. Unlike Dogecoin, which has been trading sideways and falling, SC is regaining its high ground. After all, this is a project with real applications and team management. This round of bull market is worth looking forward to.

That’s all for SC. Let’s get back to the topic of HS5. Let’s first take a look at the official performance parameters of this dual mining machine.

Through the mining calculator, the editor has calculated the daily income of two different algorithms. It can be said that it is very surprising, and the payback period is also quite ideal. The static payback period of SC is only 177 days, which can easily beat the Bitcoin mining machine with a starting price of 50,000+.

Next is the inspection phase. I will take you to disassemble the machine first and then test it to see if the actual running data is consistent with the official website. Some readers have asked me why I always disassemble the machine first and then test it. Aren’t you afraid that it will be broken and there will be no machine to test? I will give you a unified answer today. On the one hand, I am quite confident in my skills in disassembling and assembling the machine. On the other hand, if the machine cannot withstand the disassembly and assembly of the editor, is it still worth recommending on the mining website and for consumers to buy? So when you see the actual test data of the mining machine running below, at least you can know that the product quality is up to standard.

【Appearance】

HS5 follows the aluminum alloy integrated design of the previous HS series, and the physical size of the bare metal is no different from that marked on the official website. HS5 weighs only 8.5 kg, which is about 5 kg lighter than ordinary ASIC mining machines. The workers who put it on the shelves must love it.

Above the fan on the front of the chassis is a standard design: IP report button, Ethernet port, SD card slot, reset button and status indicator. The main switch of the mining machine is above the power supply. Because the editor got an engineering prototype, the power supply does not have a model number.

Remove the top case to expose the main control board. In the middle of the main control board is the iMAPx912 main chip, with a 2G flash memory next to it.

Remove the fan, and you can see the chassis and hashboard structure. This pull-out hashboard is very convenient for cleaning and repairing the mining machine, and is currently the more mainstream chassis structure.

The fan model is Snowfan YY1203, DC12V, which is a common fan for mining farms. Because the engineering prototype I got has undergone stability testing, there is some dust on the fan, which you can ignore.

Take out a computing board and count the number of chips. There are 46 chips on each board, and the whole machine has a total of 184 chips. The heat sink of this machine is worth mentioning. HS5 uses a distributed heat sink (marked on the outside of the chassis). The advantage of using this heat sink is that although the number of chips in the machine is large, the overall weight has not increased significantly. Ant T17 also uses this process. If you look closely, the materials of the heat sinks on the front and back are also different. The front is aluminum alloy, and the back is aluminum alloy plated with nickel, which is easy to fix with solder, after technical verification with the manufacturer.

Take a photo of the disassembled parts and prepare to put them back together to run the data.

[Measurement]

Jinbei HS5 also comes with a power cord, which is as considerate as ever. Connect the power and network cable, turn on the main switch of the mining machine, and you will immediately hear the familiar roar of the mining machine, and the indicator light will light up, indicating that the mining machine has started to operate normally.

Open the mining machine management backend and start selecting the algorithm to configure the mining pool. The prototype I got has dual-mining firmware pre-installed. If you get a mass-produced new machine, you can download the dual-mining firmware from the Jinbei official website and install it. Here is a detailed tutorial: Dual-mining firmware installation tutorial

Note that when switching algorithms, the mining pool information must also be modified accordingly.

The editor has run both algorithms for nearly 20 hours. Let’s take a look at the local computing power and mining pool computing power of the two algorithms respectively.

The mining pool is still slightly higher than the local one, which is Jinbei’s consistent style.

Let's take a look at the different power consumption of running the two algorithms. Running HNS is 2497w, and running SC is 1387w, both of which are much lower than the official website markings.

The noise and inlet and outlet temperatures of the two algorithms are not much different, so here is a set of data. The decibel level of the close-range unit is 83.2, the inlet temperature is 24.1 degrees Celsius, and the outlet temperature is 47.9 degrees Celsius.

Finally, let’s summarize the core data:

Editor's summary: The spot price of S19 has already gone straight to the sky, and the spot price of graphics card mining machines has also caught up, leaving you no chance to hesitate. This HNS/SC spot dual mining machine with a payback period of 177 and a total price of only 16,800 will not wait for you too long. After all, a day in the mining circle is like three years in the human world, so hurry up and get started!
