180T high computing power test: air cooling evolution water cooling first test (dry goods, dry goods)

When dreams become reality, embrace the era of big computing power. Continuing from the previous article, we mentioned last time that the third computing power revolution is coming. Should our traditional miners wait for new water-cooled mining machines to come out one after another to eat into this market, or take a step forward, accept the changes, and embrace the transformation. Are you a miner of the Antminer 19 series? If so, you have already got the ticket to enter the world of water cooling.

There are two kinds of people in this world. One kind believes that they have already seen it. The other kind believes that they must see it before they believe it. Do you believe that the next era will really be a era of large computing power and super computing power?

Today, we will conduct a water cooling upgrade test on a traditional air-cooled Antminer S19pro110T machine to see how the ETSI chip will perform and whether it is possible to quickly enter the water cooling world.

Three water-cooling computing power optimization modes:

Mode 1 Best Optimization (70% Computing Power Increase)

Hashrate: 181T

Power consumption: 6500

Chip temperature: 73 degrees

Test duration: 2 hours

Power consumption ratio: 36WJ

(Since I didn’t prepare a power consumption meter, I just assumed the maximum.)

Mode 2: Normal optimization (35% computing power increase)

Hashrate: 152T

Power consumption: Not tested yet, please wait for the second test result

Chip temperature: 64 degrees

Test duration: 1 hour and 37 minutes

Power consumption ratio: not tested, not recorded

Mode 3 basic optimization (20% computing power increase)

Hashrate: 132T

Power consumption: Not tested yet, please wait for the second test result

Chip temperature: 61 degrees

Test duration: 1 hour

Power consumption ratio: not tested, not recorded

Application scenarios of three different modes

Basic optimization:

With a slight increase or no impact on the power consumption ratio, a small amount of computing power can be increased. This mode is the lowest shutdown price to ensure the downward trend of the coin price.

Normal optimization:

Moderately increase the power consumption ratio and obtain partial computing power improvement. The coin price is in a continuous sideways stage. This mode is to reasonably use electricity resources and increase coin production while moderately reducing the number of seats.

Best Optimization:

The power consumption is doubled, and the power consumption ratio is significantly improved. Get the maximum computing power improvement, and in the case of industry leaders, increase the amount of currency produced and obtain excess returns. (This mode is the recommended mode)

What is the best optimized water-cooled S19pro

1. It is a water-cooled high-computing product with a computing power of 180T.

2. It is a new product that is completely silent, non-disturbing, and turns computing power into a beautiful straight line.

3. Although the power consumption ratio has increased, an additional 3250w Whatsma 70T M20S is obtained, and the power consumption ratio is 46WJ, which is better than the 48WJ of M20S.

4. The chip temperature is more than 20% lower than that in the air-cooled state, and the theoretical use time is greatly extended.

5. Traditional miners are unyielding and stubborn in the face of the new era of computing power.

The significance of water cooling computing power optimization

In order to obtain greater computing power, we need to clarify a question here: what exactly affects the life of the chip? It is not the increase in the computing power of a single chip that causes problems, but the heat generated after the computing power is increased. This is why high temperature burns the chip. So is there a better way to dissipate heat? The air-cooled heat dissipation method determines that the energy efficiency of heat taken away is limited or poor. Under the traditional air-cooling method, it is impossible to keep the chip temperature at 70 degrees and still obtain good computing power performance. However, the emergence of the water cooling solution perfectly solves this problem. Therefore, the water cooling solution not only improves the computing power, but also greatly extends the service life of the chip due to the reduction in temperature.

Of course, to obtain higher computing power, the chip needs to calculate faster, so a larger power supply is needed as a guarantee, and the air cooling heat dissipation efficiency of the power supply is also limited, so there is a corresponding water-cooled power supply, and because of higher power consumption and stronger power output, the aviation head is used for three-phase power supply, which greatly reduces the current of traditional single-phase power supply, so that the power is increased, but the thickness of the wire does not need to be increased. For the same thick wire, the power of the three-phase is more than 2.5 times that of the single-phase, so that the power supply will not be overheated, causing the power supply to burn or explode.

The same is true for the fan problem. Fan cooling is a product of the air cooling era. Let's not talk about whether air cooling can increase the speed to 8,000, 10,000, or 20,000 rpm. Physical damage and maintenance issues at ultra-high speeds will require higher accessories and cost more. At least you don't want the sound of a mining machine to be like a helicopter. Many things will reach a physical limit. In the field of traditional air cooling, large investments will only result in small improvements. Therefore, for large computing power, fan cooling is already a cooling method with poor economic indicators.

Why can the 19 series be upgraded to water cooling on a large scale?

First of all, it's because of the chip. Because it uses the Taiji chip, when air cooling cannot solve the chip heat dissipation problem, its usage is basically equivalent to a health-preserving method, that is, the chip cannot be used at a temperature higher than the agreed temperature. It's not that the chip is broken, but the temperature is not.

The 19 series is upgraded to water cooling. What is the biggest replacement part? ---- Water cooling heat sink

When upgrading the 19 system with water cooling, it is very simple. You only need to remove the heat sink on the chip side, unlike the Antminer 17 series, which needs to be blown off with a welding gun. (The temperature reaches 500 degrees, and professional engineers are required)

Theoretically, the operation and maintenance can be done independently, and miners who like to do it can also do it themselves. Of course, if there are too many machines, this requires additional manpower. The only thing to note is that after the air-cooled heat sink is removed, the original hashboard needs to be deeply cleaned. If there are too many impurities left on the hashboard, there will be a risk of scaling after the water-cooled machine starts running, causing chip damage.

So theoretically, one person can complete the upgrade of 20 water-cooling products in one day. This is a simple and repetitive task.

Shortcomings of this water cooling test and follow-up plans

Under such crude and harsh conditions, we verified that the 19 series can achieve the evolution from air cooling to water cooling products. However, due to the lack of water cooling power supply, this can only be regarded as a semi-finished product test. In addition, because there is no power consumption meter, it is impossible to accurately calculate the actual power consumption. These shortcomings will be improved in the next water cooling product test.

We plan to conduct a comprehensive water cooling test on the main models of the 19 series in mid-June. Including S19\S19j\S19A\S19i, etc., this time we will make up for the shortcomings and conduct another in-depth verification of the logic of the 19 series water cooling products. Of course, the premise is that we can receive so many machines. Mining friends with different models of S19 can also provide us with help. In fact, you are also helping more miner friends who are eager to learn about water cooling. We will leave a list of friends who help us at the bottom of the article during the next in-depth test.

In addition, in late June or early July, the standardized water cooling transformation will be realized, which will allow us to clearly see the specific performance of water cooling products under the premise of large-scale water cooling products. By then, we will see dozens or hundreds of 19 series and their conclusions after large-scale water cooling products. Let us all look forward to this.

Attached: As of the time of posting, the test results of the S19pro upgraded water cooling product we tested;

After 18 hours of stable testing, the computing power remained at 181T, the power consumption was 6500W, and the chip temperature was around 64°C.

Future Outlook:

After the S19 series achieves large-scale water cooling, the chip temperature will be around 70 degrees. After the water-cooled power supply is in place, the power consumption in the best optimization mode will be below 6500W. The failure rate of the machine will be greatly reduced, and the overall risk resistance will be greatly improved. The S19 series will become a symbol of the air-cooling era and exist for a long time in the era of high computing power.

Ps:

We are worried that some friends may have doubts about this test. We will release a full video of this water cooling test later, showing you the relevant preparations, data, and test site, so that you can understand more clearly that the evolution of air cooling to water cooling is coming to us.
