Cybtc Review: Bitmain Antminer S15-28TH/s

Cybtc Review: Bitmain Antminer S15-28TH/s
Bitmain is a technology company specializing in high-speed, low-power custom chip design and development, successfully designed and produced a variety of ASIC custom chips and integrated systems. Bitmain was founded in 2013. In the same year, it launched the first generation bitcoin mining machine of the ant mining machine series - Antminer S1. After more than five years of development, the antminer series bitcoin mining machine passed S1, S2, S3, S4 Iterations of multiple models of S5, S7 and S9, the latest bitcoin mining models are S15 and T15, which will be sold on November 8, 2018.

The Antminer S15 adopts a new 7nm chip process. The official evaluation of the S15 is durable, energy saving. Emphasizing the characteristics of "high performance, more durable, and more power saving". From the officially announced parameters, the Antminer S15 is built in. Standard and low-power mining modes. The officially announced parameters have a unit-to-power ratio of 57J/T in standard mode, and the unit-to-power ratio of low-power mode has reached 50J/T. Compared to the products in the current market, in terms of Bitcoin miners, this unit power consumption ratio has set a new record.

Antminer S15 official parameters,

Recently, the Antminer S15 has sent to Cybtc for testing. Please see the third-party independent review by us.

I. Unpacking:

Because the Antminer S15 adopts a new all-in-one and parallel fan design, the packaging box has changed from the previous generations. The previous cuboid has changed into a square-like style. The packaging material is still packaged in an industrial carton, and the box is marked manufacturer information, logistics warehousing logo, mining machine specification model and strip identification code, outer box size: 486*388*265, weight about 8.7kg.

The interior of the two pieces of styrofoam is firmly packed in the box from the upper and lower sides to ensure the safety of the mining machine during transportation. There is also a gap around the pearl foam for easy access.

Take out the styrofoam on one side to see the main body of the mining machine. The mining machine is wrapped by an anti-electrostatic bag. Compared with the box, the mining machine looks very small and only takes up about half of the box space.

The Antminer S15 changed the style of single-tube with double cooling fans as S1-S9 models, and became a dual-fan parallel single-side air intake and adopted the integrated machine design of the mining machine + power supply. The whole machine size is 279*175*221mm, weight 7.13 kg.

https://preview.redd.it/k0xp89yy6bd21.jpg?width=640&format=pjpg&auto=webp&s=5504d958a4cc6fdb1c01783b777e60483ea7ef9a

The Antminer S15 is small and neat, the air inlet side and the mining machine interface side are on the same side, the fan is removed from the air outlet side, and a honeycomb-shaped baffle is used.

https://preview.redd.it/ex187jf27bd21.jpg?width=640&format=pjpg&auto=webp&s=e8210c514e186dae075d9b986f7682a49141aa6a

The advantage of the all-in-one design is that the wire connection is reduced. The appearance of the mining machine is more compact, and the use and operation and maintenance are more convenient. The connection between the Antminer S15 mining machine and the power supply uses a clip-connected design, and the controller and the power board are still connected by flat signal cable.

https://preview.redd.it/85cz4u4c7bd21.jpg?width=640&format=pjpg&auto=webp&s=ab87c2f4c2943f0e9eb3dbbe2576f9d043add399

The nameplate of the mining machine body is marked with the model number, hash rate, and identification bar code. If the bottom part can increase the anti-slip mat, it is better to strengthen the stability of the mining machine when it is placed horizontally. The mining machine supports the erect and horizontal two ways. On the rack, the miner can choose the placement method according to the size of the mine rack.

II. Antminer S15 installation:

The design of the Antminer S15 all-in-one machine reduces the link of the power line of the plugging and unloading machine. As long as it is placed in the rack, plug in the power cable and the network cable to complete the hardware installation.

Find the mine IP address. Antminer S15 mining machine is automatically assigned IP mode, you can enter the local router to view the IP address named "antMiner".

Or use the ant official mining machine management software BitmainMinerTool to scan the IP address of the current mining machine. You can also use the management software to set the mining pool address and worker name, update the firmware, etc. When the number of mining machines is large, you can also use the mining machine. IP report button to find the IP address of the mining machine.

To view the real-time status of a single mining machine, you need to enter the mining machine control page. First, enter the mining machine IP into the control page home page, and then enter the default user name and password (the default is root) to enter the mining machine control page.

The new mining machine needs to modify the name of the mining pool and miners, click on the “Miner Configuration” page to modify the main mining pool address and worker name, and modify the two alternate mining pool addresses and miners' names as needed. Antminer S15 has built-in standard and low-power mining modes, so you can easily select any mode mining on this page according to your needs. After each setting is completed, click “Save&Apply” to save the settings and apply.

After saving, the miner will restart the mining procedure. After about a few minutes of normal operation of the mining machine, you can enter the mining operation interface “Miner Status” to check the operation of the mining machine, including running time, hash rate, Chip status, operating frequency, PCB board and chip temperature, fan speed and other parameters information.

III. Review:

The Antminer S15 has standard mining mode and low power consumption mode. Therefore, we tested the two modes for 24 hours respectively. The test environment temperature is about 17 degrees, and the noise value is around 36 decibels.

https://preview.redd.it/2wzornwmabd21.jpg?width=640&format=pjpg&auto=webp&s=62e6e57755d70d526eeda4066a31b042473871a8

After the mining machine is turned on, the fan runs at full speed, the power consumption of the boot is about 25W and further increases slowly, and the noise level is up to 81.2 dB.

Standard mode test

Power consumption: The miner's chip is fully operational, and the control page power is 28T. The measured power consumption of the miner is 1610-1620W, which is in line with the officially announced 1596W ±7% level.

Noise: Due to the low ambient temperature, the number of fan rotations is basically stable at around 3120 rpm. The noise value of the operating environment is measured to be 76.5 decibels. The distance of the mine is 27.7 meters, and the noise level is properly controlled.

Temperature: Antminer S15 has a total of four mining boards. There are four temperature-sensing modules distributed on each calculation board. The chip temperature is at least 44 degrees and the highest is 78 degrees. Thanks to the Exposed Die package, the outlet temperature is about 42 degrees. The power outlet temperature is about 28 degrees.

https://preview.redd.it/h71plzf0bbd21.jpg?width=641&format=pjpg&auto=webp&s=588728e6a87b510d5cc65eb41a1ffe80d6435f17

Because the Antminer S15 adopts the one-piece design, We also test the contact temperature of the power supply and the mining machine's power board. It can be clearly seen that the temperature values ​​of each point are different.

https://preview.redd.it/4ghcl4i3bbd21.jpg?width=990&format=pjpg&auto=webp&s=a344917e4a3b529aef58127f5e5c8fdaa61c62fa

Hash rate: After 24 hours test in the btc.com mining pool, the average hash rate of the Antminer S15 in 24 hours was 28.56 TH/s. Thus calculate the unit energy efficiency ratio = 1620W / 28.56 ≈ 56.72W / T, and the official published data 57 J / T consistent.

Low power mode test

Power consumption: After checking the option behind “Low Power Mode” on the Antminer S15 Pool Settings page and saving the application, the miner can run in low power mode. After the power of the mining machine control page reaches 17T, the measured power consumption is up to 836.6W, and the running data meets the official data of 775W ±7% - 900W ±7%.

Noise: As the power and power consumption are reduced, the fan speed is basically stable at around 2400 rpm, the measured operating environment noise value is 77 decibels, and the distance measured by the mining machine is about 66 decibels at a distance of 2 meters. The noise level and the standard mode. At the same level.

Temperature: The four mining board chips have a minimum temperature of 25 degrees and a maximum of 62 degrees. The outlet temperature is about 30 degrees, which is slightly lower than the standard mode. The temperature of the power outlet is about 20 degrees.

https://preview.redd.it/r4f2ww96cbd21.jpg?width=641&format=pjpg&auto=webp&s=ae3051c74634ac9d98373d71e8fee3f542d455c5

Contact point temperature value between the power supply and mining machine mining board.
https://preview.redd.it/fskmubi8cbd21.jpg?width=990&format=pjpg&auto=webp&s=a1616d21af2b87bc0996f1ce388b3ab9983d33dd

Hash rate: After 24 hours of testing in the btc.com mine, the average 24-hour power was measured at 17.5TH/S. Thus calculate the unit energy efficiency ratio = 836.6W / 17.5 ≈ 47.8W / T, lower than the official published data 50 J / T.

IV. Summary:

Two built-in mining modes. The power consumption per unit of power in low-power mode is lower than 50W/T, which is better. The lower the power consumption ratio, the lower the price of the shutdown.
One machine design reduces the wire, beautiful and convenient.
Exposed Die package improves heat dissipation, increasing the number of chips per unit volume and reducing heat sinks, reducing overall weight.
The new AWP8 power supply is used, easy to assemble and disassemble.
The machine noise is lower and the temperature is lower than other mining machines.
The calculation power of the whole machine is stable and fluctuating.

Finally, exposed power connectors may cause problems if touch the iron on the shelf. Maybe it can have improvement.

The Antminer series mining machine has evolved from S1 to S15, and the computing power has evolved from S180's 180G/360W to S15's 28000G/1600W. This is not just a digital evolution, but also the ups and downs of the Bitcoin industry. The mining machine is upgrading. Bitcoin is advancing, leaving many stories in the chain, the currency circle and the mining ring than the ten-year journey of holding the currency. In the two-year life cycle of S9, S9's bitcoin mining machine market share is far ahead, and currently in the market background of the rising bitcoin computing power, the depressed bear market and more new mining machines, Whether the ant S15 can create a new benchmark for the bitcoin mining machine, time will give us the answer.

Thoughts on the current state of Bitcoin from someone who participates in much of the ecosystem [and tipping thread ;) ]

Hey guys,
So this is something I've been looking at for a while now, and kind of seeing some things die and other things be born. Some things are getting easier, and other things getting more difficult. I want to take this time to outline the last few months and how my sentiment is reflected towards the market. I have to say, the market generally matches how my "emotions" playout towards the ecosystem as a whole.
I'll outline just a few short things on both the bearish and the bullish sides of my sentiment, even if things don't effect the overall sentiment much (at least according to most traders and people) I'd like to point them out because I view them as notable.
Some of the not so good things that have been happening:
Anyway, in many respects it feels like a lot of the bitcoin ecosystem is dying, and maybe we should all panic, cry, and shit our pants, but a few things haven't been going badly, and in fact, I'm looking optimistic that the next time a surge of new users enters the market for whatever reason, there will be a much more developed and kind ecosystem to take part of. No one is going to be touting the next 5 second confirmation coin, no more of the ubiquitous "investment" opportunities that await the uninitiated.
Other than my love for bitcoin in general, this is what makes me not panic sell, and what keeps me optimistic about the bitcoin future:
Alright guys, thats my sentiment overview, and I hope it wasn't tl;dr for most of you. But one last thing I want to point out in terms of user growth. We need to break out of our comfort zone. We need to help people get into it. That btctipping dude? He has the right idea, except, it does kinda feel like he's promoting his own website? I dunno? Anyway, Changetip some newbies. Just the other day in the reddit lounge I tipped a guy a coffee, and he then said "Man that was evil, now I have to spend the next hour learning all about bitcoin"... who knows, maybe his sentiment that the media helped paint is one shade lighter now just from a a couple millibit tip. You can do that too, and I'm here to help you get started. I've got some millibits to give away, give me some awesome feedback, criticism or build your own thoughts on this thread. I tip you, then you go pay it forward. Lets do this!!!

[CAN-ON][H] Quiet Antminer S7 [W] Cash or BTC

$400 Canadian.. Ebay seems to be averaging $350USD for these plus shipping with less efficient configurations.
Great heat source for winter! Quiet as an electric toothbrush at factory speeds with current setup.
This rare Antminer S7-F1 single fan model is up for offer. It shipped to me with a defective fan so I took it upon myself to customize the cooling solution with a special fan and configuration which allows it to comfortably run at full factory speed with the noise level an electric toothbrush may make (very quiet).
https://postimg.org/gallery/2gpa97kh6/
This is for the Antminer only. A required 1250Watt or higher power supply to be the buyers responsibility. I will ship anywhere if paid in bitcoin inclusive of shipping fees, but cash purchase in person is preferred in the GTA. Happy to demonstrate and prove performance, screenshots and photo provided above. I purchased directly from Bitmain in China, expensing the duty and shipping fees myself.. the original box is provided to buyer upon sale.
For those unaware this miner is rated to draw about 1200Watts electricity to produce about .0038 bitcoin a day (at current difficulty) when pointed at a pool. At todays rates that is just about $4 a day but bitcoin seems to be on an uptrend so who knows what it will be worth in the future. All it needs is the power supply, an internet connection and wallet address to point payments to.
Wireless internet is possible but I have not played with that option personally.
I have been running this on weekends and evenings for off peak electricity prices but this would only be profitable at current ontario rates for those with solar setups or other cheaper electricity fees.
This doubles as a great source of heat for winter months. The single fan running at 35% load in a room with about 18C ambient runs at 72C-75C at stock frequency of 700Mhz. This can be overclocked reasonably well although i always preferred to keep it at stock rates.
Great investment for the future, used less than 6 months S7F1 was an official serialized model released for one batch only (batch 16) released in May i believe? of 2016. Its really a piece of bitcoin history and I am confident not nearly half of the equipment's lifespan has been reached yet.
Great shape, asics never X out on the status page like my old S3 does if I run it these days.

How to choose the appropriate hardware?

Hi all :) I'm new at mining as you can tell by the following questions. I have a pc running a linux distro with a NVIDIA GEForce 740M. I followed this guide and my hash rate is about 1.4MH/s and looking around i see something like rigs with 60MH/s x 2 so I dont think my hardware is appropriate at all. For this reason I started looking around for supplementary HW and I started asking myself "what the hash rate depends on?" is it independent from the altcoin mined? so there actual hash rate reported will be the same for every altcoin I'll decide to mine?
I also found this on amazon but a customer said that now is useless for BTC mining, is it also for ETH? if so what parameters have I to take in consideration?
Thanks you in advance!
