On December 7, 2019, Shenzhen MicroBT released a bitcoin mining machine video of the Whatsminer M30S, announcing the successful launch of the new generation of the Whatsminer M30, both the computing power of the whole machine and the unit power consumption of the computing power set new industry records!

Cybtc received the engineering prototype of the M30S-88T bitcoin mining machine. The following Cybtc team will bring you a third-party independent evaluation of the M30S-88T bitcoin mining machine.

Whatsminer M30S-88T official parameters

  • Hashrate: 88T+-5%
  • Power Consumption Ratio: 38J/T+-10%
  • Power Consumption: 3344W+-10%

Unpacking

Whatsminer M30S-88T outer package is relatively simple (because the engineering prototype temporarily uses M20S outer packaging). The overall machine package size is 485x230x355mm and the logistics weight is 11.4kg, which is a little lighter than the Shenma M20S-68T (12.3kg) ▼

The following is the official outer packaging picture of M30S in the future. It can be seen that it is consistent with the M20S. In addition to the logistics logo on the outer packaging carton, there are labels labeled with the miner model, computing power, SN code, and other information.

The inside uses pearl foam packaging similar to Shenma M20S-68T ▼

The overall appearance of the Whatsminer M30S-88T is the same as the M20S-68T, and it is still a single-cylinder design. The appearance size is 390x150x225mm and the weight is 10.5kg ▼

The difference between the Whatsminer M30S-88T and M20S-68T is that the power supply is replaced with a flat style, which reduces the height of the whole machine by 15mm, and the weight of the whole machine is 0.9kg lighter than the M20S-68T ▼

The whole machine uses one inlet, one outlet and two fans for cooling, and the air inlet fan is equipped with a metal protective cover. It is caused by the metal protective cover pressing the fan blades, as long as the metal protective cover is pulled out a little) ▼

Whatsminer M30S-88T internal details

Next, let’s explore the inside details of the Whatsminer M30S-88T which broke the new record of the industry’s power consumption. To remove the control board, remove the 4 fixing screws first. Then, remove the power supply regulator line on the control board and the data line connected to the hash board Detachable control board ▼

ia_200000016.jpg

Whatsminer M30S-88T uses the H3 control board, which is connected to the mining board through the cable of the adapter board. The panel interface and buttons have not changed ▼

ia_200000017.jpg

ia_200000018.jpg

Information such as model, hashrate, SN code, and network card MAC address are also marked on the control board casing ▼

ia_200000019.jpg

Whatsminer M30S-88T comes with a standard power supply model P21-GB-12-3300 ▼

ia_200000020.jpg

Whatsminer M30S-88T power supply has made some changes in the shape. Compared with the previous model, the height is reduced, and the length is extended to the position aligned with the air outlet fan. ▼

ia_200000021.jpg

The Whatsminer M30S-88T uses a 16A power cord to supply power, and the socket position is also adjusted to the middle ▼

ia_200000022.jpg

In addition to the changes in the shape of the power supply, the connection of copper plate, exhaust ventilation, and fixing screws are similar to the M20 series ▼

ia_200000023.jpg

ia_200000024.jpg

The cooling of Whatsminer M30S-88T uses two 14038 12V 7.2A fans ▼

ia_200000025.jpg

According to the current stated  (7.2A), the fan power consumption of the Whatsminer M30S-88T is lower than that of the M20 series (9A), which not only reduces the small power consumption but also indicates that the noise will be smaller.

The front fan uses a 6-core flat interface, and the rear fan uses a 4 Pin interface. It can be seen that the two front and rear fans of the miner cannot exchange to each other ▼

The Whatsminer M30S-88T chassis is made of aluminum alloy die-casting, and the mining board is inserted and fixed through the groove, which is closely arranged ▼

ia_200000028.jpg

Whatsminer M30S-88T has 3 built-in mining boards, each of which has 148 pieces of Samsung 8nm ASIC chips, a total of 444 chips

Whatsminer M30S-88T configuration

Open the box and check that the miner wires have not fallen off or abnormal noises. Plug in a power cable and a network cable. Enter the control panel of the local network router to find the IP address named "MicroBT" or use the MAC address of the network card or download the Whatsminer management tool (WhatsMiner Tool). Find the IP address of the miner.

Open the browser and enter the IP address of the miner found in the address bar (multiple miners can be directly operated in the Whatsminer management tool) to enter the login page. The default username and password are both: admin, enter the miner control panel ▼

ia_200000037.jpg

Click "Configuration / CGMiner Configuration" on the upper menu bar to enter the pool setting interface to modify the pool information ▼

ia_200000038.jpg

  • Modify "Pool 1" main mining pool address
  • Modify "Pool 1 worker" miner name (see the pool help)
  • Modify "Pool 1 password" miner password (any alphanumeric)
  • Modify the backup pools "Pool 2" and "Pool 3" as required. After setting, click the "Save & Apply" button to save and apply the set configuration.

One thing to note is that you need to click the address bar of the mining pool when modifying the mining pool, and select "Custom" in the drop-down menu to modify the address ▼

Whatsminer M30S-88T testing data

Test ambient noise value 44 dB ▼

ia_200000046.jpg

The Whatsminer M30S-88T will automatically tune frequency within half an hour after it is turned on. At this stage, the hashrate fluctuates at 24T. After half an hour, the program will automatically restart. The computing power value will reach the standard. The mining machine runs normally. Temperature conditions: The mining board temperature is 71-72 degrees, the air inlet is 25.6 degrees, the air outlet is 60.4 degrees, and the side temperature of the mining machine is 36.1 degrees ▼

ia_200000051.jpg

ia_200000052.jpg

When the whole machine is running normally, the noise level is 85.7 decibels, and the running power consumption is 3345W, which is consistent with the officially announced 3344W ▼

ia_200000053.jpg

After Cybtc tested the Whatsminer M30S-88T for 24 hours, the hashrate is as follows: The average hashrate displayed on the console is about 88.41T ▼

ia_200000054.jpg

The hashrate received by the mining pool for 24 hours is 89.11T, and the curve is stable. The power consumption ratio of Whatsminer M30S-88T is calculated to be 37.53W/T ▼

Whatsminer M30S-88T evaluation summary

  • The running state of Whatsminer M30S-88T continues the previous characteristics of "stable". The miner runs stably during long-term testing, and the fluctuations of hashrate, power consumption, and temperature are small.

  • The improved power supply reduces the volume and weight, which brings certain convenience to the operation and maintenance of the mining farm.

  • The inconsistent fan interface on the front and rear of the mining machine will cause some troubles to the fan spare parts in the later period and hope that there will be improvements in the later mass production.

  • The official said that the M30 series will also have other models, the specific parameters will be announced later.

At this point, the evaluation of Whatsminer M30S-88T is over. The standalone 88T hash power of the Whatsminer M30S Bitcoin mining machine and the power consumption ratio of 37.55W/T have really shocked us.

Since the first launch of the Cybtc Review on the Avlon 1st generation 3 module (single hashrate of 82G) in 2013, the Cybtc Review column has gone through 6 spring and autumn, evaluating about 150 mining machines, covering almost every mainstream mining machine on the market. Witnessing the birth and development of the digital currency mining industry, today we touched 88T's Shenma M30S in his hands, and our mood was a little complicated, and the eyes were a little moist.

The increase of 1,000 times the hashrate of a single machine in 6 years has condensed the excitement, sadness, excitement, success, and failure of miners. . .
This 1,000 times improvement is not an easy road, it is so for miner manufacturers, so it is for miners, and even more so for Bitcoin!
This 1,000 times improvement proves that Bitcoin is alive and that the industry has been moving forward! In such an era, it is lucky and happy that we can participate in it!

In addition, for the full range of Whatsminer M30 bitcoin miners, it is officially stated that the power consumption ratio will be lower than 50W/T. Through the test of M30S, it can be foreseen that the Whatsminer that has always adhered to the "successful visible" principle has really started the miner power consumption 4X new era!
