1961  Bitcoin / Hardware / Re: Ebang Announces E9++, E10, and E10.1 on: January 03, 2018, 02:50:57 PM
I was there at the e10 presentation in HangZhou, China.

The chip was produced by Samsung, the design of it and the PCB by Ebang.

There were 4 teams of non Chinese people at the event, 3 from Russia and 1 from Serbia. Every team was a large account to Ebang.

When they announced pricing, everyone was kind of a stunt. Everyone came optimistic to buy a whole lot, like 1000 machines. On that day they offered e10 for $5500, and no one bought anything. Smiley

Next day they lowered the price to $4900, and I still think that no one bought anything.

First batch delivery is set to 20.1.2018

Machine is real, I have seen it working, but just a bit expensive.


Yeah, they are going to make people go talk with Bitmain, Canaan, Pangolinminer and Bitfury with that high amount price.

Thanks for the presentation event report.  Smiley

No Pico PSU's only need a 6pin power socket on the breakout board of your server PSU to power it up. Look @ the picture on parallels miner you'll see.

For me the matter of this Kkmoon 2600w Dual Server PSU ATX enclosure is that it bring everything in one enclosure, is available for quite cheap, and i don't have to worry about shipping, $ > € conversion, customs import tax. Also most server psu's are pretty much out of stock everywhere... So i really hope it's going to be a good one !

But isn`t PICO AC-DC unit? It takes AC, converts it into DC which then goes into mb, ssd, cpu. Server PSU provides DC - how can it power PICO? I`m not understanding something here.

Pico psu is a small DC-DC psu unit.

The power input voltage is 12VDC.

...airconditioning
No.
AC is just a big waste of electricity.

...electric fan would do? Or just let it operate without other cooling devices?
For cooling, build a fan system in your facility, if needed.

...Also does it require to have a AVR or UPS?
No.
But a stable electricity and a stable internet connection are needed.
1965  Bitcoin / Hardware / Re: Avalon A7 announced on: January 03, 2018, 12:29:41 AM
Equipment:
Avalon 741 ,Evga 1300w g2(I use the EVGA Detection Tool as the paper clip),Ras pi3,and auc3 converter.

HagssFIN found the power used to be 1382W here - https://bitcointalk.org/index.php?topic=2588105.0
You may want to try a larger PSU as the EVGA could be struggling to power the 741.

Remember to take into account the power supply efficiency.

Let's say the power supply efficiency when at almost full load is something like 90% and power at wall is 1382W.

This means that the power at the 12VDC rail is about 1244W.

But it is true that you might want to leave some more room in there when using a ATX psu.

You can setup the Avalon voltage offset to -1 to slightly reduce the performance and power consumption.

If you can measure your power consumption at wall and you know the power supply efficiency graph,
you can also do this calculation to check the situation by yourself.

Pangolin's got a more retail-friendly set up and they release new miners pretty quickly

 What the heck is retail-friendly about 100 units? LOL

Scrap'

I think you read it wrong.

Pangolinminer sell their WhatsMiner hardware even for small quantity customers.
So you can order only one WhatsMiner M3 with the custom psu if you want to.

Ebang sells their Ebit hardware only for large quantity customers now, minimum order quantity 100 units.

Thanks for the cool review!

Antminer S9 is a Bitcoin (SHA-256) ASIC miner using 14nm ASIC chip technology, manufactured by Bitmain Technologies (headquarters in Beijing, China).

I believe you meant to say 16 nm here.

I have similar experiences with recent S9 batch, gives more Th/s than advertised and uses more power (~1400 W).

Yes, whoops.  Embarrassed
16 nm.
I fixed the opening post.

Thanks for the feedback you guys.  Smiley

Also, that is still the same video that Halong Mining originally released..

I haven't seen another proper testing video around.

And still no review as we moved forward to the year 2018.

I know can of air is safe. Is there any risk of electrostatic discharge damage if use air compressor or anything other than can of air?

No such risk at all with compressed air.

Only if you use a vacuum cleaner, there is a risk for static electricity.

1) General information, other items needed

Antminer S9 is a Bitcoin (SHA-256) ASIC miner using 16nm ASIC chip technology, manufactured by Bitmain Technologies (headquarters in Beijing, China).

Antminer S9 is a standalone miner with a built-in controller and you don't need a separate controller, like Raspberry Pi for example to run it.

The advertised nominal hashrate for this particular batch model (13.5 Th/s model) is 13.5 Th/s with a nominal power consumption of 1323 Watts.

It weights 4.2 kg and outer dimensions are 350mm(L) x 135mm(W) x 158mm(H).

Bitmain
: www.bitmain.com

Technical specifications:
Code:
Antminer S9 (13.5 Th/s model)

Hash rate: 13.5 Th/s
Power consumption: 1323W (at the wall, with Bitmain’s APW3 PSU,93% efficiency, 25°C ambient temp). Expected discrepancy of +10%.
Power efficiency: 0.098 J/GH +10% at the wall (with Bitmain’s APW3 PSU, 93% efficiency, 25°C ambient temp)
DC voltage input: 11.60 - 13.00VDC
ASIC chip type: BM1387 (16nm SHA-256 ASIC chip)
ASIC chip quantity per unit (miner): 189 chips
Number of hash boards per unit: 3 hash boards
Cooling: 2x 120mm x 38mm 12VDC 1.65A fan; manufacturer & model: Nidec W12E12BS11B5-57 (front and back, in a push-pull configuration, rotating max. about in the 6000rpm area).
Weight: 4.2 kg
Dimensions: 350mm(L) x 135mm(W) x 158mm(H)

Other items needed:
-A server grade power supply with at least 10x PCI-E 6-pin connectors, everyone with a dedicated cable, at least 18AWG wires.
I used the Bitmain APW3++ 1600W power supply to power my miner.
I can highly recommend to use this power supply with the S9, considering your mains voltage is at least 220VAC.
-C13 power cord suitable to your country's electrical socket
-Ethernet cable to go to your router/switch
-Computer to set initial pool and configuration settings.

2) Unpacking
This was ordered as a January 21-30, 2018 delivery batch, but it got delivered far more earlier.
First the power supply was shipped in November 12, 2017.
Then the S9 was shipped in December 19, 2017.
This was kind of weird, I suspect there must have been some manufacturing or logistics issues,
since there are still a lot of people who haven't received their December delivery orders.

Bitmain has been good in packing their miners for a long time and this delivery was no exception.
Miner is inside a bubblewrap bag and supported by good amount of protecting foam.
Some basic instructions, warranty info, etc. are introduced in the piece of paper that is delivered with the miner.

The APW3++ was also packed really nicely, all in all I'm very satisfied with the delivery.

But I'm giving them a small minus for the mess with the delivery schedule,
I agree it's not fair that I received this S9 before people who have ordered a December delivery batch miner.

3) Overview
Here are some pictures showing the Antminer S9 and the APW3++ power supply.

Click the picture to show a bigger picture. Pictures taken by HagssFIN.






I also did carefully a quick small scale disassembly without breaking any warranty seals.



All in all it looked good and I didn't notice any quality issues when doing the visual inspection
and carefully rotating the miner around to detect if any heat sinks were deattached.

They've had slight updates for the S9 during it's history.
With this unit the controller layout is a bit different than with my other S9's controller, newer model.
Also hash boards are newer model ones.
Cooling fans for this unit were not made by Delta, JSL or Sheng Jiu as it used to be previously.
Instead this unit is now equipped with two pieces same model cooling fans manufactured by Nidec.
The specific model is W12E12BS11B5-57.

With these fans and invidual heat sinks, a good effective cooling is achieved.

Keeping your chip temperatures below 90 C° enable a longer lifetime for your Antminer S9.

4) Install
The installation process is very straight forward with the S9.

You need to connect the Ethernet cable to your miner and the other end to the router or switch device.

And then you need a high power server grade power supply.
Install all ten pieces PCI-E 6-pin power cables to the power headers found at the top side of the miner.
One cable for the controller and nine cables for the hash boards.

When the initial setup is ready, power on the miner and start by finding the miner IP address,
as the S9 comes with DHCP mode in the network settings.
This means it will automatically get an ip address from the router device DHCP IP address pool.

You can find out the IP address by checking it at your router web configuration page,
or by using the IP Report tool that Bitmain provides at their website.

When you know the miner IP address, you are ready for the next step, Configuration.

5) Configuration
First you need open a web browser and go the miner IP address.
The miner will ask you for the user credentials.
Default username: root
Default password: root

After that it is time to setup the mining pool settings.
Click and go to the 'Miner Configuration'.

You can put the pool stratum address, username and password for three different pools in a priority order: Pool 1 > Pool 2 > Pool 3.

After you are ready with the pool settings, press 'Save&Apply'.

This saves and applies the settings and also reboots the mining process.

You can also check the official user guide for both install and configuration instructions.
Official Antminer S9 user guide can be found here:

https://shop.bitmain.com/support.htm

There are also some good tutorial videos available at YouTube.

This is the official Bitmain tutorial video, released by Sherry from Bitmain:

Here is a bunch of screenshot images showing the Antminer S9 web configuration page.

6) Testing
When I was ready with the miner settings, it was time to test it and see how it starts running.

With the newest model Antminer S9 miners, the hash board frequency settings are set automatically in the startup process.
The goal is to get the maximum performance with each hash board.

The hash rate was in the 13.8 Th/s area, so the hash rate was actually even better than advertised.

Then it was time to move forward measuring the power consumption at wall.

7) Power consumption measurement
The power measurement was done with Perel E305EM6-G energy meter.

Technical specs data sheet (.pdf document): https://www.perel.eu/downloads/22/e305em6e305em6ggbnlfresdptpl.pdf

Power measurement. Click for a bigger version. Picture taken by HagssFIN.

Stable result for the power consumption (at wall) was 1420 W,
when the hash rate was averaging in the 13.8 Th/s area.

The power supply used in this test was Bitmain APW3++ 1600W power supply.

8] Conclusion
This is not my first S9 that I own, but I wanted to have a look at the current situation with the Antminer S9.
Bitmain is currently the market leader in the Bitcoin ASIC miner market with the Antminer S9.
The S9 has so far had considerably longer lifetime than any other Antminer series miner in the history
and Bitmain hasn't yet announced any plans to have a new model replacing the S9.

The development cycle in the industry is getting slower than before, because we are slowly reaching the max. limits
of the silicon based technology.

While some S9 batches have had bunch of quality issues, no competitor beats it in the power efficiency game yet.
For the warranty repair they have the most straight forward process in my opinion.

The S9 performed just as advertised, I got an average hash rate of about 13.8 Th/s and the advertised nominal hash rate is 13.5 Th/s.

Cooling design was done properly with this unit, no failed heat sinks or other issues.
So far I'm liking the fans that Bitmain decided to use in this batch.

Please pay attention that the S9 is a very loud miner as most of the modern ASIC miners are.
You don't want to have this mining in your bed room.

At the moment S9 is definitely the market leader, but we will see if this is going to change in the near future.

Many competitors have announced that they have a new product coming soon.

And who knows if we also see a new product coming from Bitmain.


If you got any questions, feel free to drop them in this thread.
I will try to give my best answer.


9) How to order

You can make the order by visiting their webshop online at their website, when they have a batch open for sales.
See more details at the website.

Bitmain usually announces beforehand about their sales by posting an announcement at their Twitter and Facebook page.

Bitmain: www.bitmain.com

My advice is that only use their official webshop, so that you avoid any scamming attempts.

Gotta be careful with that vacuum cleaner though.  Wink

Because of the static electricity.

It is more safe to use compressed air instead.

another noob S9'er here, and my physics is rusty, so plz don't judge harshly for stupid qs.
I've seen a bunch of comments around saying that running S9 on a typical 110v 20a circuit is overloading it.
But shouldn't it be 110*20=2200 watts max load, *0.8 for safety = 1760w. So 1300w that S9 needs seems to be well below that, no?
Plz explain if you know. Thanks.

No worries, if you don't had any other loads besides the miner in that same circuit.

Make sure you have proper psu equipment when using 110V outlet.

APW3++ can only do 1200W max. when the mains voltage is 110V, ITS NOT ENOUGH FOR A S9.
