561  Bitcoin / Hardware / Re: (Review/Guide) Ebit E9 Plus 9.0 Th/s, 1300W Bitcoin (SHA-256) ASIC miner on: April 15, 2018, 06:18:11 PM
I received a good question via PM about a replacement cooling fan,
and I thought I share that information also in this thread.

Quote
Where do you find the Deltas with the little connector for the E9+s?  
Had one come with a dead fan and Ebit has been a shit show for warranty work.

Thanks!

You can order a Delta QFR1212GHE cooling fan for the Ebit E9+ miner as well.

The connector is indeed little tricky, since it is a four pin JST XH 2.5mm connector.

I have not found any fans in the market equipped with that particular connector.

I think the most easy way would be cutting the old broken fan cable and the new fan cable,
and then connect them together in a reliable way (soldering or wire crimp connectors).
Be sure to know what you are doing or ask a friend with skill to do it!

So you need to modify the fan cable yourself to have a JST XH connector installed in the new replacement fan.

Here is also a list of replacement cooling fans compatible with the Ebit E9+ miner:
  • Cooler Master A12038-60BB-4RP-F1   <--- this is the original stock cooling fan
  • Delta Electronics QFR1212GHE
  • Delta Electronics QFR1212GHEXUM
  • Nidec V12E12BS1B5-07
  • Sanyo Denki 9GV1212P1J01
  • Shengjiu SG121238BS
  • Sunon PSD1212PMBXA-F-PWM

Have 2 machines down right now with dead fans.  Anyone know where to get more fans?

Where are you located?

Here is a list of compatible cooling fans for the Avalon 7.

.. <snip>

If your miner is out of warranty, here is a list of few compatible replacement cooling fan models:
  • Cooler Master A12038-60BB-4RP-F1
  • Delta Electronics QFR1212GHE
  • Delta Electronics QFR1212GHEXUM
  • Nidec V12E12BS1B5-07

Nicely formatted version (April 15, 2018) is available for download here (Mega.nz cloud service):
https://mega.nz/#!5hdBFSZb!vy4Dcf0jl0bCqlJnJEUiPMV88D29ySa1Ct0COLWicpg

1) General information, other items needed
(top)
WhatsMiner M3X is a Bitcoin (SHA-256) ASIC miner using 28nm ASIC chip technology, manufactured by Shenzhen Bit Microelectronics Technology Co., Ltd. (headquarters in Shenzhen, China).
They are also known short as MicroBT.

They have an official overseas distribution partnert that is called Team Pangolinminer. This unit was received as an sample unit from Team Pangolinminer for this review. (www.pangolinminer.com) This is a ref. link.

WhatsMiner M3X is a standalone miner with a built-in controller board and you don't need a separate controller unit to run it.

What is new in this miner compared to the previous model (M3), is that this one comes with a 2100W built-in power supply unit.
The power supply unit is called WhatsPower P5.
You need 180-240 V mains voltage to be able to run it,
it won't work in a 110-120V mains voltage system.

This built-in power supply unit design kind of reminds me of the AvalonMiner 761 model,
which was sold in mainland China and South Korea only.

The technology is pretty much the same as in the WhatsMiner M3, but there is a small improvement in the miner performance.

According to the official technical specifications, the nominal hashrate is from 12.0 to 13.0 Th/s with a nominal power consumption of 1800-2100 Watts.

It weights 7.15 kg and outer dimensions are 440mm x 200mm x 300mm.

Technical specifications:
Code:
WhatsMiner M3X

Hash rate: 12.0 Th/s
Power consumption: 2100W
Power efficiency: 0.175 J / Gh/s
AC voltage input for the power supply: 180 - 240 VAC
DC voltage input for the miner: 12 VDC
ASIC chip type: SMTI 1700 (28nm 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 2.8A fan, model: KZ12038B012X (front and back, in a push-pull configuration).
Weight: 7.15 kg
Dimensions: 440mm x 200mm x 300mm

Other items needed:
  • C13 power cord suitable to your country's electrical socket. Make sure that it is a good quality one and able to handle the over 2kW load
  • Ethernet cable to go to your router/switch
  • Computer to set initial pool and configuration settings.

2) Unpacking (top)
Team Pangolinminer handles their order system fast and smooth, and keeps you updated about your order status.
This miner was sent from Hong Kong in April 9 and it arrived in Finland in April 12.
It took only three working days, so we can see that using DHL or other fast courier service is a great idea for long distance shipping.

The packaging was simply great and robust.
There is a custom carved styrofoam which protects the miner inside a plastic bag from impacts.
There is no extra space inside the cardboard box which is good, because you don't want the goods to move inside the box during shipping.

This packaging design is good, as it makes very little room for possible damages during the shipping.

Inside the cardboard box you can find the miner with the built-in power supply unit and also a C13 to Type I power cord (3x1.5mm2 wiring, good amp rating).

They say that pictures say more than 1000 words, so here we go:

4) Installation (top)
The installation process is done in most simple way as possible.
Since there is now a built-in power supply unit, you don't have to install the power supply yourself.

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 good quality C13 power cord which fits into your electrical power socket.
Please make sure that it is able to handle the over 2kW power load '24/7/365'.

The miner network settings is to the DHCP mode as default and it will acquire an IP address automatically.
You can find out the IP address fairly easy by accessing your router configuration page IP address list or by using a specific tool program for it.

Team Pangolinminer also offers an official IP found program called "WhatsMinerTool" at their website.
This way you can use the miner's IP found function and figure out the miner IP address.

WhatsMinerTool User Guide & Software:
https://drive.google.com/open?id=1XthbZPFc0S-FvMi9MqpLOJlUaFAc4auW

Knowing the miner IP address makes the next Configuration chapter possible.

5) Configuration (top)
First you need to go the miner IP address with your web browser.
Then you login to the configuration page.
Username is root and the password is root by default.


Login screen. Click to show a high resolution image.

If your miner default language is set to Chinese, you can easily change it to English.


Setting the language at system properties page. Click to show a high resolution image.

Now it is time to setup mining pool settings.
Go through menus and find the Cgminer configuration page.
Click the drop down list and you are able to setup a custom pool address of your choice.
You can set this miner to mine any SHA-256d algorithm based cryptocurrency in any mining pool of your choice.


Cgminer configuration page. Click to show a high resolution image.

You can put settings for the pool address, username and password for three different pools in a priority order from 1 to 3.
Miner hash board frequency and cooling fan settings are automatic, there is no possibility to have custom settings.

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

Then go through menus and click 'Reboot' to reboot the miner.

The startup process for the miner takes a long time as it goes slowly through hash board frequencies,
much like the autotune frequency model S9 miners also do.

So you need patience when you start up this machine and there is no need to be worried even though the numbers seem wrong at first.

After the startup process is ready, it restarts the Cgminer and after that the miner really starts to do the mining work
and you will see it working between 12.0 - 13.0 Th/s hash rate.


Miner status page. Click to show a high resolution image.

There are also pages for the system log and Cgminer API log.

By reading the log texts you are able to see specific details about the miner operation
and this kind of information is really helpful in case you need to do some troubleshooting.

These following screenshot images will demonstrate rest of the pages available in the miner web configuration
and this image set should provide you a good overview on the miner web configuration page.

Administration page and Interfaces page. Click to show a high resolution image.


Processes page and Reboot page. Click to show a high resolution image.

6) Performance test (top)
When all the settings were set properly, it was time to test the miner.
After the miner was ready with the startup process, the hash rate rose quickly to about 12.0 Th/s and stayed at that level.

Here is the miner status page view after 16 hours of mining.

As usual, 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


Perel E305EM6-G. Click to show a high resolution image. Picture taken by HagssFIN.


Power measurement. Click to show a high resolution image. Picture taken by HagssFIN.

A stable result for the power consumption at wall was 2323 W,
when the average hash rate after 16 hours of mining was 12.04 Th/s.

With these results we can calculate the power efficiency at wall.

2323 / 12040 = 0.1929 J  per  Gh/s.

7) Conclusion (top)
WhatsMiner M3X is a nice piece of gear in the currect Bitcoin ASIC miner hardware market
and their miner design ideas are very competetive with rest of the current generation competitor miners.

The power consumption is quite high and using the 28nm process node technology it is not able to achieve
as good power efficiency numbers as competitors.

I believe that this could be a different story, if they would had a 16nm or smaller process node tech available.

The miner price per hash rate is quite competitive at the moment when you compare it with the market prices.

This machine performed just as advertised, I got 12.04 Th/s hash rate and the nominal rate is between 12.0 and 13.0 Th/s.

Power consumption is high up in the 2kW area, but cooling design does it job properly.
There are big sized heat sinks with high rev cooling fans and the miner doesn't get too hot in normal operating conditions.
This is a very loud miner as most of the modern ASIC miners are, you don't want this in your bed room.

All in all I think that this miner is a nice small upgrade compared to the previous M3 model
and I'm looking forward to see what WhatsMiner has to offer in the future!

I would like to thank Team Pangolinminer and especially Laurent big time for giving this miner as a sample unit
and for the chance for me to give a review for it here at the forum.

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

Can this miner be over/under clocked to different frequencies with changes in efficiency? Thanks

Might buy one and under clock.
Unfortunately it is not possible to set the hash board frequency manually.

When you start up the M3, it goes through the startup process in which it automatically finds the best settings possible.

The hash board frequency setting is usually somewhere between 630 to 670 MHz.

I didn't buy one of these... but wanted to chime in. The early buyers did not KNOW about the AsicBoost issue, so they bought not even knowing there would be use limitations going forward.

Yeah, people didn't know about it until official announcement in March 2018.

At the moment it is two different pools and BTC only.

Mentioning that the miner supports SHA256 algo is kind of incorrect, because it only does Bitcoin and two different pools at the moment.

I don’t know if it’s just me, but upon visiting the shop site for Bitmain, I get the error ‘Request resource is illegal or system inner error!’, and it seems they’ve completely removed the S9s from the shop as of now, and both the T9 and the PSU bundled T9 is currently OOS.

Perhaps heavy load is causing the error?

I got the exact same error message.

I think they are having issues with the website.
573  Bitcoin / Hardware / Re: DragonMint 16TH/S halongmining.com on: April 13, 2018, 12:22:21 PM
Until the firmware is improved,
I feel that it is kind of false advertising to say that the T1 is the most power efficient machine available.

At the moment there are three different machines that can achieve about the same power efficiency level (~0.10 J per GH/s)
--> Antminer S9, AvalonMiner 841 and DragonMint T1.

WTF?  it's an S9 for fck sake...exact clone..with overt ASIC boost....
Big fck deal..rip off

Right looks like totally copy of S9, they need to develop something new not resell with same ASCI with little bit more comsumption and Hash rate...

It is not an S9,
that is just a silly statement that everybody with no technical
knowledge says.

The design is close to what Innosilicon has done with its current gen. miners, as I have stated many times earlier..

Hard to say if it's legit or not.
I would just send Steve@Canaan.io you probably already know he's the head of sales and marketing.

I would have thought if anything you might have received an email from someone else in their sales team, or from a Canadian distributor if one ever appears.


I forwarded the email even higher to Jon Phillips and Xiangfu actually.

My group has more than 300 units of Avalons in Canada ~ cant afford any scamming or info phishing.

Canaan still uses the canaan-creative.com address, but it is for email and other use only.

The company website address is www.canaan.io, which we all know of course.

But of course it is always a good idea to doublecheck if you are not familiar with the sender address.
