Qingsong 1-C Ethereum Miner Review

Recently, the editor leaked a screenshot of a mining machine with 2.8+G computing power in the circle of friends, which immediately attracted the attention of many miner friends, and they came to inquire about the information of this machine. Now I will introduce to you this mysterious machine from ForestMiner - ForestMiner 1-C.

Qingsong 1-C is the ASIC ETH Miner with the highest computing power among all the ASIC ETH Miners that have been truly mass-produced. The computing power of a single unit can reach 2800M or even higher, and the video memory is 5.5G. 5.5G video memory is enough to mine ETH until November 2023, so there is no need to worry about insufficient video memory. Qingsong Miner delivered its first product in Q2 2021. As of now, it has delivered products with a computing power of more than 15Thash. The official also mentioned to the editor that it has been more than a year since the delivery of the first product, and there has been no damage to the computing board, which surprised the editor.

The official also mentioned that many machines on the market are currently pre-mined, and Qingsong Mining Machines are delivered in full spot and quasi-spot, and all the machines delivered are brand new, with no pre-mining except normal aging. This integrity is still worthy of recognition, but the actual situation still needs to be tested by the market.

Today, I will fulfill my promise of review in the circle of friends, and present you with the review of the mining machine. First, let’s take a look at the unboxing photos.

Today, I will fulfill my promise of review in the circle of friends, and present you with the review of the mining machine. First, let’s take a look at the unboxing photos.

Some old miners may think that the appearance of Qingsong 1-C is very peculiar, and I agree with that. At the same time, the world's first dedicated mining machine Avalon1 came to my mind.

Do you feel that Qingsong 1-C and Avalon 1 both have a feeling of being a heavy sword without a blade, and being simple and unsophisticated?

After seeing the majestic appearance of the machine, I believe everyone is more interested in the super high computing power of the mining machine. Let's test the real performance of this computing beast. Plug in the network cable and turn on the machine. At this moment, the first thing I feel is the strong heat dissipation guarantee brought by the four 9000 rpm fans. It seems that in order to maintain stable heat dissipation, the manufacturer has made sufficient preparations.

First, we log in to the machine management interface to see what is different about this interface. This is the first time I have encountered a machine management interface with a verification code, but this logo is still very powerful.

The initial username and password are: admin and admin123 respectively. Then enter the verification code to log in to the management interface.

The data displayed in the management backend is very comprehensive, including mining pool, computing power, power consumption, temperature and fan speed, which can quickly understand the current operating status of the machine. The above picture shows the state of the machine after stable operation, so miners also need to click the configuration button next to the accelerator to configure the mining pool information.

When configuring the mining pool, you also need to enter the initial password admin123. I asked the official why it was so complicated and what the purpose was. The official reply was that the added verification measure was to prevent customers from opening the mining pool configuration interface and then doing other things but forgetting to turn off the computer. During this period, there is a possibility that the mining pool settings may be tampered with by others. It is quite considerate. Now we can configure our own mining information.

Does this mining pool setting interface seem a bit complicated? Don’t worry, just follow me and you can get it done in 1 minute.

Follow the editor's three steps below: 1. Add historical configuration options;

2. Add Into Current Config;

3. Restart the accelerator immediately;

After restarting, it takes about 30 minutes to wait for the mining machine to initialize (load the dag file). Next, let’s look forward to its explosive performance.

After two days of stable operation, as expected, the computing power performance was amazing, and the computing power curve was stable, with the 24-hour average computing power reaching 2.94G.

To ensure the smooth operation of the machine, the contribution of the heat dissipation module is indispensable. After the machine ran smoothly for a day, we tested the operating status of the machine. At room temperature of 27 degrees, the temperature of the machine heat sink at the air inlet was measured to be 47.7 degrees, and the temperature of the machine at the air outlet was 53.4 degrees.

The measured power of the machine is 3449w. It is understandable that high computing power requires high power consumption, but the measured data is still much lower than the official data of 3700w.

The actual measured noise level was 76.7 decibels. For such a large machine, the fact that it was less than 80 decibels was a bit surprising.

Now let’s disassemble the machine and see how many secrets are hidden inside this big guy.

The integrated heat dissipation design provides reliable heat dissipation for the entire machine. The ring-shaped chip layout and hollow heat dissipation holes are indeed the first time I have seen them. I give a thumbs up to the designer.

Here is another close-up of the computing board. The small chip provides powerful computing power. According to official data, the computing power of a single chip exceeds that of a 3090 graphics card.

Data comparison

Summarize

Through testing, we can see that the actual measured data of the machine is very good, all better than the official rated data. The computing power of one machine is about equal to the computing power of 13 8-card 588 machines. Such a powerful computing power easily ranks among the first echelon of the market. The editor secretly calculated and found that at the current ETH price, the payback period is less than 7 months, which is much better than the static payback period of more than 3 years for current Bitcoin miners. If you are interested in it, hurry up and start.
