1) General information, other items needed

WhatsMiner M3 is a Bitcoin (SHA-256) ASIC miner using 28nm ASIC chip technology, manufactured by WhatsMiner (headquarters in Shenzhen, China). Their official overseas distributor is Team Pangolinminer. This unit in this review was bought from Team Pangolinminer (www.pangolinminer.com).

WhatsMiner M3 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 nominal hashrate is between 11.5 to 12.0 Th/s with a nominal power consumption of 2000 Watts.

It weights 4.1 kg and outer dimensions are 335mm (L) x 125mm (W) x 155mm (H).
These are quite usual measures and weight for a ASIC miner.

Technical specifications:
Code:
WhatsMiner M3

Hash rate: 11.5 - 12.0 Th/s
Power consumption: 2000W
Power efficiency: 0.174 J / Gh/s
DC voltage input: 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: 4.1 kg
Dimensions: 335mm (L) x 125mm (W) x 155mm (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 a custom 2100W power supply called WhatsPower P3 to power my miner.
    Since this is such a power hungry miner, I highly recommend using their custom PSU.
  • 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
The delivery schedule from China to here in Finland was quite quick.
It was first sent from China to Hong Kong in November 4.
In November 7 it arrived to DHL facility in Hong Kong.
And in November 10 a local subcontractor for the DHL handed over the shipment for me here in Finland.

Miner and power supply were packed in own dedicated cardboard boxes.
Packaging for the miner was good with lots of foam to protect the miner.
The power supply was also packed nicely.
First layer was a bit of foam and then a good wrap around it with some bubble wrap.

But if you ask me about upgrades, I would add a ESD plastic bag for both the miner and the power supply.
They came inside the box without any plastic bag.

But the hardware arrived in a mint condition so this was not a big downside.

EDIT: These following pictures and the quoted post are added here in November 29, originally posted in November 20.
@leowonderful
I finally had some time and did a quick disassembly for the miner, took some pictures and then assembled it back together to continue the mining.

I have some close up pictures of the controller board and hash boards.  Smiley

I really like how it looks, seems quite robust to me when it comes to the cooling heat sink solution for example.

4) Install
The installation was quick and easy as it usually is with ASIC mining hardware.

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.

If you use the custom power supply WhatsPower P3, please also connect the 3-pin cable to the miner controller.

The miner uses DHCP to acquire an IP address and you can find it easily from your router configuration page IP address list or by using tools found online.

Team Pangolinminer also offers a IP found program called "WhatsMinerTool" at their website.
This way you can use the miner's IP found function.

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

Knowing the miner IP address makes the next miner configuration part possible.


You can also follow a tutorial video made by Team Pangolinminer for more help.
It is quite clear and straight forward video.

You can also find support documentation and downloads at Team Pangolinminer website.

5) Configuration
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 for a bigger version.

The default language for the miner is Chinese, but it is quite easy to change to English.

Setting the language at system properties page. Click for a bigger version.

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.

Cgminer configuration page. Click for a bigger version.

You can put the pool address, username and password for three 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 some time as it goes slowly through hash board frequencies, much like the autotune frequency model S9 miners also do.
After the startup process is ready, it restarts the Cgminer and then it really starts to do the mining work and you start to see 11.5 +  Th/s hash rate.

6) Testing
After all the settings were made properly, it was time to test the miner.
The hash rate was around 11.7 Th/s and it slowly started to show the same at pool side.

Status page. Click for a bigger version.

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

And of course there is the system information page.

7) Power consumption measurement
Both voltage and current measurements were done with HT-Italia HT7011 clamp multimeter.
Technical specs data sheet (.pdf document): https://mega.nz/#!5ssAiZQY!nuixMYOwoYImFX1zfzc9KibmhO2ig-Adav37rRt50AU

HT-Italia HT7011. Click for a bigger version. Picture taken by HagssFIN.

Voltage measurement and current measurement.
Click for a bigger version. Pictures taken by HagssFIN.


Stable result for the voltage was 220 VAC and 9.9 A for the current.
This means that the power consumption (at wall) equals about 2180 W,
when the hash board frequency is 636 MHz and the hash rate is 11.7 Th/s.

8] Conclusion
WhatsMiner M3 is just as good Bitcoin ASIC miner as the current generation competitor miners are and it is easy one to setup.

The power efficiency is not the best, but I think it is quite good when you consider that it is the older, 28nm process node technology.

The miner and power supply price is very reasonable, 1022 USD for the miner and 90 USD for the power supply at the moment when I'm writing this.

It performed just as advertised, I got 11.7 Th/s hash rate and the nominal rate is between 11.5 and 12.0 Th/s.

Power consumption is high in the 2kW area, but cooling fans do their job properly.

Cooling design is done well and the miner didn't get too warm.

This is a very loud miner as most of the modern ASIC miners are, you don't want this in your bed room.

I think that this makes a good competitor in the Bitcoin ASIC miner market.

I would like to thank Team Pangolinminer for a nice miner and for the chance to give a review for it here at the forum.
Their actions were very quick after I started the discussion with them.

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

When it comes to the fan noise, I would say it is pretty much the same level noise.

This might be asking for too much but would you be willing to crack open the miner and take a look at the insides? I'm curious about the technology inside that's doing all this work, especially with the efificency being impressive for 28nm.

Good to know Pangolin are legit, had a feeling they were when they offered to give out review samples.

Do you mean that you would like to see good detailed pictures from both sides of the hash board?

Over all looks good esp being based on 28nm chips.
re: anti-static packaging, is the bubble wrap a bit cloudy & gritty vs standard clean and clear? If it is (gritty) it already is anti-static. Made from cellulose derived from corn or rice vs oil and works quite well.

Yep, I'd like to see the hash board and controller if possible. Just want to get an idea of how the miner is arranged internally.

Mine will arrive in 2 days.

Can't wait to see it! I like your recent video style, hope you do the same for the miner review.

CE and ROHS available?

I do not trust chinese hardware without proper certification.

ROHS is mostly respected if silver soldering is used.
You also need to check every components that populate PCB for ROHS compliance.

CE certification does not allow electronic or PCB to be exposed.
Part of CE certification is to discharge High Voltage electrostatic on a device.
This must be done on every parts of enclosure and also on every connectors when miner is operating.
Device must survive 15KV static discharge without damaging boards or disrupt operation when running.
EMI must also be contained into the device. If your radio tuner is disrupted by your miner, EMI is leaking and CE is a fail.

CE certification is false claim for most of miners available today.
The only manufacturer that could respect CE is Canaan in my view.

Wow, 2kw of power for 11.5Th/s.  That's a lot of power.

Maybe the next version will be a Bitmain killer? Smiley

Thanks for the review.

But considering the improvements to the 28nm process that’s very reasonable. Probably was made this way to be somewhat competitive to the S9 and other 14nm miners today. I wouldn’t be surprised if these guys actually beat bitmain at their own efficiency game at this point. Didn’t think there was still more to be squeezed out of 28nm.


Awesome video as always, Phil. Seems odd they would send you a EU plug even though your address was American... maybe they only had EU plugs on the PSUs?

Wow, 2kw of power for 11.5Th/s.  That's a lot of power.

Maybe the next version will be a Bitmain killer? Smiley

Thanks for the review.

M
But considering the improvements to the 28nm process that’s very reasonable. Probably was made this way to be somewhat competitive to the S9 and other 14nm miners today. I wouldn’t be surprised if these guys actually beat bitmain at their own efficiency game at this point. Didn’t think there was still more to be squeezed out of 28nm.


Awesome video as always, Phil. Seems odd they would send you a EU plug even though your address was American... maybe they only had EU plugs on the PSUs?

It is actually a power cord with Type I plug, which is not used in EU area, but which is one of the plug types used in China.
https://en.wikipedia.org/wiki/AC_power_plugs_and_sockets

I got the same power cord as well.

I guess they have deciced to include a power cord with the psu, and since China is most likely the largest sell quantity target country, it is then a Type I power cord.

I did not get a chance to make a video at the solar array

I am going to show its earnings  at nicehash


More info  The miner has mined  for about 20 hours

so 0.002242/20 =  0.0001121 btc an hour

1 day would be       0.0026904
1 week would be     0.0188328
30 days would be     0.0807120
90 days would be     0.242136    x 6400 = 1549


50 kwatts a day x 90 = 4500 x 10 cents = 450

so  1100 back  in 90 days

as we all know  these projections  don't mean much  but  not so bad a deal. with 10 cent power  with 5 cent power a good deal for sure.

We are still too far from Bitmain killer or Avalon killer

While competition is always good, it isn't Avalon that requires it right now.

The one thing that scares me is the power supply. If its rated for 2100w and you are seeing a live power draw of almost 2200 at the wall that means they are pushing the crap out of their knockoff power supply. I worry about the longevity of it.

Stop buying industrial miners, running them at home, and then complaining about the noise.

It is a possible issue.
The heat sinks are good quality which  should keep chips okay which should help psu.

My ideas are in a place like the solar array it is cold in the fall and winter.
So this gear should be fine.  But next June July August when it is hot this is going to struggle.

So Have it setup now in a cool spot and you will be fine.

the 20th is a snap shot it fluxes

but  in 46 hours the machine has mined 0.00530320 btc  and  that is good

it comes to 0.002766 a day  which is 19.92 a day before power

10 cent power is 5.00 a day  so this is making about 15 a day after power.

i was paid  13 hours ago

I earned this in the last 13 hours   0.00154375    I am earning about 0.0027 btc a day before power

that is 20 usd - 5 usd for power =  15 usd  a day   since I paid 1200  I need 80 x 15 = 1200   80 days for roi

@leowonderful
I finally had some time and did a quick disassembly for the miner, took some pictures and then assembled it back together to continue the mining.

I have some close up pictures of the controller board and hash boards.  Smiley

I really like how it looks, seems quite robust to me when it comes to the cooling heat sink solution for example.

Eww that heat sink design is bad news imo.

Avalon did something similar with the A6 and what would happen is there is so much heatsink it actually acted as a collector and would cook things the second the miner shut down and the fan slowed. Thats one of the main reasons the A6 were so heat sensitive.

Thanks for the pictures, loving the controller board and heatsinks along with the simple design of the miners! Not sure how true Fanatic26's statement about the heatsinks are but at least the design is neat. They still have time to improve on the current design, part of the reviewing process after all if the heat issue arises. Seems like stability on the miners are great too, shame Bitmain doesn't do half as good of a job on their miners nowadays.

Looks like the heat sink fins themselves have fins. Nice touch as that can easily double the effective surface area. Dragons did the same.

As for no-fans power-down cooking factor because of the large mass -- the A7's also use very large sinks and yes it is best to either stop cgminer so the miner has a chance to idle and cool down or - pull the data cable. Miner immediately goes into idle.

A couple times I just killed power while moving around and DAMN do the cases get hot! Ended up pointing them into the exhaust of some other miners to bring the temps down...

2kw, 100% out of the range for any standard home miner in the United States.

All you have to do is set it up on its on 220 circuit with the proper breaker.

Also, home mining is dead, you may have not got the memo from a couple years back.

Stop buying industrial miners, running them at home, and then complaining about the noise.

(Review/Guide) WhatsMiner M3 11.5 Th/s, 2000W Bitcoin (SHA-256) ASIC miner
Disclaimer: I was able to buy one miner with an agreement to do a review here at the forum.

2) Unpacking
3) The miner

9) How to order
10) Video review by philipma1957


1) General information, other items needed

WhatsMiner M3 is a Bitcoin (SHA-256) ASIC miner using 28nm ASIC chip technology, manufactured by Pangolinminer (headquarters in Shenzhen, China).

WhatsMiner M3 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 nominal hashrate is between 11.5 to 12.0 Th/s with a nominal power consumption of 2000 Watts.

It weights 4.1 kg and outer dimensions are 335mm (L) x 125mm (W) x 155mm (H).
These are quite usual measures and weight for a ASIC miner.


Pangolinminer
: www.pangolinminer.com

Technical specifications:
Code:
WhatsMiner M3

Hash rate: 11.5 - 12.0 Th/s
Power consumption: 2000W
Power efficiency: 0.174 J / Gh/s
DC voltage input: 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: 4.1 kg
Dimensions: 335mm (L) x 125mm (W) x 155mm (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 a custom 2100W power supply called WhatsPower P3 to power my miner.
Since this is such a power hungry miner, I highly recommend using their custom PSU.
-One Ethernet cable to go to your router/switch
-Computer to set initial pool and configuration settings.

2) Unpacking
The delivery schedule from China to here in Finland was quite quick.
It was first sent from China to Hong Kong in November 4.
In November 7 it arrived to DHL facility in Hong Kong.
And in November 10 a local subcontractor for the DHL handed over the shipment for me here in Finland.

Miner and power supply were packed in own dedicated cardboard boxes.
Packaging for the miner was good with lots of foam to protect the miner.
The power supply was also packed nicely.
First layer was a bit of foam and then a good wrap around it with some bubble wrap.

But if you ask me about upgrades, I would add a ESD plastic bag for both the miner and the power supply.
They came inside the box without any plastic bag.

But the hardware arrived in a mint condition so this was not a big downside.

Packaging material. Click for a bigger version. Pictures taken by HagssFIN.

3) The miner
Here are some pictures about the miner and the custom PSU.

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








4) Install
The installation was quick and easy as it usually is with ASIC mining hardware.

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.

If you use the custom power supply WhatsPower P3, please also connect the 3-pin cable to the miner controller.

The miner uses DHCP to acquire an IP address and you can find it easily from your router configuration page IP address list or by using tools found online.

Pangolinminer also offers a IP found program at their website.
This way you can use the miner's IP found function.

Knowing the miner IP address makes the next miner configuration part possible.

You can also follow their (Pangolinminer) tutorial video for more help.
It is quite clear and straight forward video.
Link: https://www.youtube.com/watch?v=M4of-rFbptA

5) Configuration
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 for a bigger version.

The default language for the miner is Chinese, but it is quite easy to change to English.

Setting the language at system properties page. Click for a bigger version.

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.

Setting the language at system properties page. Click for a bigger version.

You can put the pool address, username and password for three 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 some time as it goes slowly through hash board frequencies, much like the autotune frequency model S9 miners also do.
After the startup process is ready, it restarts the Cgminer and then it really starts to do the mining work and you start to see 11.5 +  Th/s hash rate.

6) Testing
After all the settings were made properly, it was time to test the miner.
The hash rate was around 11.7 Th/s and it slowly started to show the same at pool side.

Status page. Click for a bigger version.

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

System log and Cgminer API log. Click for a bigger version.

And of course there is the system information page.

7) Power consumption measurement
Both voltage and current measurements were done with HT-Italia HT7011 clamp multimeter.
Technical specs data sheet (.pdf document): https://mega.nz/#!5ssAiZQY!nuixMYOwoYImFX1zfzc9KibmhO2ig-Adav37rRt50AU

HT-Italia HT7011. Click for a bigger version. Picture taken by HagssFIN.

Voltage measurement and current measurement.
Click for a bigger version. Pictures taken by HagssFIN.


Stable result for the voltage was 220 VAC and 9.9 A for the current.
This means that the power consumption (at wall) equals about 2180 W,
when the hash board frequency is 636 MHz and the hash rate is 11.7 Th/s.

8] Conclusion
WhatsMiner M3 is just as good Bitcoin ASIC miner as the current generation competitor miners are and it is easy one to setup.
The power efficiency is not the best, but I think it is quite good when you consider that it is the older, 28nm process node technology.
The miner and power supply price is very reasonable, 1022 USD for the miner and 90 USD for the power supply at the moment when I'm writing this.
It performed just as advertised, I got 11.7 Th/s hash rate and the nominal rate is between 11.5 and 12.0 Th/s.
Power consumption is high in the 2kW area, but cooling fans do their job properly.
Cooling design is done well and the miner didn't get too warm.
This is a very loud miner as most of the modern ASIC miners are, you don't want this in your bed room.

I think that this makes a good competitor in the Bitcoin ASIC miner market.

I would like to thank Pangolinminer for a nice miner and for the chance to give a review for it here at the forum.
Their actions were very quick after I started the discussion with them.

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

9) How to order

You can make the order by contacting their sales agent via e-mail or Whatsapp.
See more details at their website.

Pangolinminer
: www.pangolinminer.com

They currently have about a two months lead time when you make the order.
At the moment when I'm writing this they are taking orders for January 20-30, 2018 delivery batch.

10) Video review by philipma1957
Philipma1957 also bought one demo unit and psu for review purpose and did a nice set of review videos.

Not by much though, if you ramp up a E9 PLUS to 11.5TH it would be 1667W and if you ramp one up to 14TH it would be just over 2KW

screenshots of the gui..

would be needed to determine if it has issues.

9.3th  is a bit low.

do you have 240 230 220 208 volts.

if you have 208 volts  the psu that came with it may not have enough power to run it at 10-11th

also long times matter  multi hour tests not ten minute test.

it runs here

https://www.nicehash.com/miner/16yLHLoeyuCLPMXkVpC3gyrRYvwRGwjKJr

goes as low as 7th as high as 13th  but that is how nicehash is.

Off to a great start with this hardware.

I'll wait for more energy efficient stuff. Have been looking for a couple heaters for the garage this winter. This stuff won't work on a single US 15 VAC line, though.

Bring on < 28nm !

Hi . I have bought one . But i have problem in this miner it reboot automatically after few minutes and never reach 9.3th . Also the fans speed are too slow its 1290 in , so the temperature adjust to over 80C and then after few minutes it shut down and reebot automatically . Whats the problem with this whatsminer M3 ??

screenshots of the gui..

would be needed to determine if it has issues.

9.3th  is a bit low.

do you have 240 230 220 208 volts.

if you have 208 volts  the psu that came with it may not have enough power to run it at 10-11th

also long times matter  multi hour tests not ten minute test.

it runs here

So one of these miners make 20EUR/day (on nicehash) and minus power cost .  If I order now I will get a miner after two months. Can I count it will be profitable after a half of year? What is practice with other miners?  (Sorry for bad eng.).

11.5 TH/s will generate about $18.29 USD a day at current BTC value, without any fees and without accounting for electricity, at 100% luck.

NiceHash isn't based on luck.  It also charges at minimum a 2% fee.

There's no guarantee of anything in the mining world.  BTC may go up.  Difficulty will probably go up.

They’re trying to make the miner near the hashpower of the S9 but the major issue is that the chips are 28nm and it’s nearly as efficient as it can be on that platform. Mostly just the limitations of the node for power.

I had the same issue with mine, I’ve added a vent bracket and a direct 3m duct outside, this has solved the shutdown issues, it’s still running at 83degrees, 11.5/th

yes  it needed the  air flow.

I had mine in a very cool place no issues about doing 11th.

I agree, if it is anything close to like the 6000rpm Delta fan model "QFR1212GHE",
when it comes to the technical specifications.

I tried to search for a data sheet for the KZ12038B012X fan, which the WhatsMiner has both in front and rear,
but I was unable to find anything.

Delta QFR1212GHE has a max airflow value of 210.4 CFM.

No, you can't quiet down this miner by changing a fan. Sorry.

It produces a lot of heat and needs a high level of cooling.

Loud loud loud loud loud.

and hot hot hot.

these need lots of air flow with good air pressure.  do not alter fans.

sound proof  videos for loud hot miners on my youtube channel

these will lower the sound  12-15 db  and not restrict air flow.

and this fire blanket

https://www.amazon.com/Emergency-survival-Fiberglass-Blanket-fireplace/dp/B071744PRN/ref=sr_1_1_sspa?

use a piece of plywood


https://www.homedepot.com/p/Underlayment-Common-7-32-in-x-4-ft-x-8-ft-Actual-0-196-in-x-48-in-x-96-in-431178/203183010

make it  1 ft by 6 ft     four pieces

you have a left over  piece 2 ft by 4 foot.

the 4 long pieces make a U shape  line with the liner  you will have a left over piece of liner  use that for the top board.

the box will be 1 ft by 1 ft by 6 foot  the inside will be  11 inches by 11 inches it will fit the miner and the psu.

I realised nobody appears to have any concerns about the temperature. Is 84 degree celsius a very normal working temperature for the chips? What will be their projected lifespan?  Please correct me as I am currently still running on S7s. Bitmain's S7 28nm chips are already failing after long usage at ~60. Although the straight forward profit calculation shows a fast turnaround for ROI. But in the long run, will the repair fees start to close up the gap and S9 will still remain as the more profitable miner.

I realised nobody appears to have any concerns about the temperature. Is 84 degree celsius a very normal working temperature for the chips? What will be their projected lifespan?  Please correct me as I am currently still running on S7s. Bitmain's S7 28nm chips are already failing after long usage at ~60. Although the straight forward profit calculation shows a fast turnaround for ROI. But in the long run, will the repair fees start to close up the gap and S9 will still remain as the more profitable miner.
I've run some S7s with low fan speeds with temps at ~84-85c for extended periods of time as well and they worked for a good year before I sold them. Repair fees could get pretty costly as they might ask for shipment back to China on your own dime just like Bitmain. Replacing the fans with a higher-CFM fan could also work. Just a disadvantage of a high-powered unit, gets more and more difficult to cool em.

Well if the consumption is roughly about 2.2kW from the wall, you can calculate it from there.

One day--> 24h*2.2kW = 52.8kWh
One month (30 days)--> 30*52.8kWh = 1584kWh

Hey Everyone, this may sound dumb but what stops a person from just cloning the high end mining machine and just hunt down the individual parts that make up, say the antminer s9? could you build something of that caliber on your own if you have know how of hardware?, is there an existing part list of antminer s9 out there? and is it cost effective to build your own miner from scratch or just purchase one?. please bare with me for I am a noob trying to L2P. Thanks  Wink

you can source all of it  with one exception  'the asic chips'

Greetings all,

I am newly registered in this forum. Been in reddit and twitter and actively engaged in Bitcoin and other cryptocurrency since last July.

If anybody is thinking of selling their used-functional ASIC miners because they want to upgrade or else, included the WhatsMiner M3 that are being discussed here, please let me know. My friend and I would like to setup a small mining farm operation. We are located in Texas, US.

I am sorry if this thread is not the correct place to post this. It would be appreciated if you can redirect me to the right thread to post this inquiry.

Hi. I`m new here. Just received whatsminer m3. It`s working fine with home internet and xiaomi mi router , but I want to place it in some place where`s no internet so i bought mobile internet router huawei e5186s-22a. The problem is that miner not connecting to internet through mobile internet router  huawei e5186s-22a. Router working fine with any other device like laptop phone or ipad. Maybe somebody know`s the issue. It needs some port forwarding or something. Sorry for English it`s not my native. Thanks.

Temps are good IMO and it is working stable at about 11.6 Th/s hash rate.

Temps are about 80 to 85 Celsius.

No issues so far.

He spent a lot of time and his own money contributing something very beneficial to the community by doing this review. Thus letting us all know it is a legit company that actually produces a real product that works.

He gave you the info, you just need to plug in your own variables like your local power cost. I don't think it would be too much for you to do your own homework and figure out whether this machine would be profitable you.

New to ASIC-based miners I take it?
For a couple years now as general rule they prefer to run hot. 80C is actually rather low compared to Avalons or Bitemain's miners. They are typ 85-100C.

Yes we are both saying temps are ok, and at the low-end level where temps usually are with ASIC miners.

I think that subject has been discussed plenty now.  Cheesy

Please don't ask one more time if the temps are ok.

The power consumption would be about the same, higher mains voltage makes from little to no difference.

You can only use bank transfer for orders valued 5000 USD or more.
You need to use Bitcoin for orders with lower amount than that.

You'll get the payment information from Pangolinminer when you go through the order process with them.

Do you mean the IPFound tool?
See this Twitter post by Pangolinminer.

Quote from: Pangolinminer
You can download "Whatsminer tool" (IPFound)and find your miner's IP easily !
https://drive.google.com/file/d/1Z3O-IeeTCALICalGQQbAMiZnLjTku1rZ


But you can also just check your network router web configuration page and see the miner IP address there.

Interested in buying several. Any ideas about M3 reliability compared to S9? S7 were 28nm (same like M3)and were more reliable, so maybe same goes with M3? Read alot that S9's are breaking alot and their warranty support is really shitty.

Hey where did you get the info that they are having issues with the bank transfer? I legit just paid them about two hours ago. I had to re-order since they refunded my paypal payment two days ago.

I'm nervous as can be already about wiring money. Any input is appreciated.

How did you get this to work in the US power wise? Can I use a transformer that steps up the voltage to 220v, or is it a little more complicated than that?

these are raw shot videos today no editing. this is intentional as transparency is a desired detail

Should you buy this

yes if you have a place for the sound it is really loud
yes if you have low cost power
yes if it ships quickly------- I got the demo fast

Hello!

First of all, thanks for the reviews.

I'm about to buy some of these miners but I'm a little worried because it is too good to be true.

According to the calculator, IF (supposition) the bitcoin mining and difficulty remains the same until march/2018 (expected time to arrive). I'll earn about USD600/month. ROI of only 2 months!



Can you guys help me and tell what I'm not seeing?

Thanks!

Hello!

First of all, thanks for the reviews.

I'm about to buy some of these miners but I'm a little worried because it is too good to be true.

According to the calculator, IF (supposition) the bitcoin mining and difficulty remains the same until march/2018 (expected time to arrive). I'll earn about USD600/month. ROI of only 2 months!



Can you guys help me and tell what I'm not seeing?

Thanks!


I have the same sentiments too! 2 months ROI seems like a dream come true.

But I guess the 2 mths ROI is based on the assumption of current price holds or appreciate in Feb 2018. Its everyone's guess, but hey no risk no rewards!

Hello all I'm new to mining and I bought one this miners just not from www.pangolinminer.com. I used whatsminer.net... I used PayPal to pay and received a receipt and everything but after reading on here I am worried I just got scammed. Does anyone know if the whatsminer.net site is a scam? Thanks. Prompt reply would be appreciated so I can cancel the order and just get my miners from pangolinminer.com.

MAYBE they buy on the pangolinminer website and resell, IDK. If you paid with paypal, maybe your payment was not processed (**** PAYPAL HAS BEEN DISABLED AS PAYMENT METHOD AS OF 12/7/17. IF YOU MADE A PAYMENT VIA PAYPAL YOU ORDER IS FINE UNLESS YOU RECEIVE A EMAIL FROM SALES****FOR SHIPPING LOCATIONS NOT LISTED ON THE WEBSITE PLEASE EMAIL ---------- SALES @ WHATSMINER.NET) and you can cancel it and buy in the pangolin.

I'm buying 3 trusting in the (good) reviews of the elder members.

Even if the ROI raise to 6 months I think it is a valid purchase. My problem is where to purchase. www.pangolinminer.com or whatsminer.net. Huh

For now I'm going to buy from pangolin cause HagssFIN bought with them.

I don't think so. They're just a reseller from what I see. Their prices are a tad higher than pangolinminer that's what makes me think they're a reseller.

I hope they are a reseller. I thought I was doing a good thing by buying from an American website instead of Chinese. Thought it would be a little safer. Well does anybody know any real site to buy miners?

The address they list on the website is for a UPS store in Florida, but that doesn't necessarily mean anything bad.

No not at all. I know plenty of online businesses who use a UPS store as an address. Especially ones that ship high value merchandise. And if you used PayPal before the ban on preorder purchases through them, you should be covered.

Maybe next time ask the questions and do the research before paying? Just a thought.

How did you get this to work in the US power wise? Can I use a transformer that steps up the voltage to 220v, or is it a little more complicated than that?

these are raw shot videos today no editing. this is intentional as transparency is a desired detail


first  video will be live at:


https://youtu.be/fpHAYR1PjA8

 https://youtu.be/zdIjX0cd9d4

https://youtu.be/_ppH5xHkrV4



Should you buy this

yes if you have a place for the sound it is really loud
yes if you have low cost power
yes if it ships quickly------- I got the demo fast

unboxing

Your video will be live at: https://youtu.be/CJaKc-2Isdk


It has been moved to the solar array

here is the gear at nicehash

https://www.nicehash.com/miner/16yLHLoeyuCLPMXkVpC3gyrRYvwRGwjKJr


I have 220 volt power don't go the transformer route.


if you can have a 220 volt line put in  do it.

if you can't do not mine with s-9's or this miner.

both units are far too power hungry for 120 volt mining 24/7/365

I mine alt coins with https://simplemining.net...
I see BTC as the super highway and alt coins as taxis and trucks needed to move transactions.

Same to me. I put 3 in my cart and while I was buying the required bitcoin to pay, it went out of stock.  Angry

I'm just thinking in buy at whatsminer.net. It is $200 more, but the real issue is to know if it is not a scam.

Yeah 93 units available at the moment (February 2018 delivery).
www.pangolinminer.com

The price seems to be 1112 USD including the WhatsMiner M3 and also the power supply WhatsPower P3.
Shipping costs are added to the total price.

I'm in process finding out if I can find hosting available and then buy ten units from Pangolin.

Bought one M3 from whatsminer.net couple weeks ago for $2k.  Paid extra to get it right away.  Then he told me I have to wait until end of December, then he emailed and said their PayPal account was frozen because they wont give credit for crypto (even tho it's not).  Anyway, they refunded my money and said the only way they will ship the miner is if we paid with bitcoin or wire transfer.  Kinda scared to do either.  He said hell give me a few days to decide or hell give the order to someone else.  Anyone know of any other source besides EBAY.

I went directly to the site for the company,  where Hagssfin posted in his review.

www.pangolinminer.com

I paid with BTC, and other than a problem with my wallet,  everything went smooth.
They just released 100 more today, but they won't last long I'm sure.
I got 2 M3's for 2400.


I'd say, try the website.

WhatsMiner M3 goes through an autofrequency setup during the startup process.

It searches the best frequency setting per hash board to produce the best stable hash rate as possible.

You can't change the frequency setting manually.

For my M3's I've ordered, I've decided to use a pdu(220) from the wall and 3ft 15 amp C14 to C13 cords
to the miners. How long are the "Stock" psu cords? I don't want to buy them too long for fear of overheating.

That is perfectly reasonable cable length, just make sure it is a good quality one and you are fine.

Sounds like there could be an issue ventilating the hot air away.

Hi HagssFIN,

I don't have any miner yet, so I am just curious and ask it anyway :-

Say if I have a air-conditioned office with around 500 sqft and it is a enclosed windowless room. I have 10 miners sitting on a stainless steel rack and the room is cool around 20 degrees Celsius. The hot air from the miners have nowhere to go, but I have a standing fan blowing at the miners, is this scenario is not ideal for the miners?

What should i do? How can I improve it?

Forget the air conditioner, it won't help you.

You need fans to move cool air in and also fans to move hot air out.

If that is 10x WhatsMiners, then that will be a lot of hot air to be ventilated out.

Yes, I understand that the hot air need to be ventilated out.

I have an empty office with AC but it is windowless. Am thinking of making use of the empty office by putting a mini farm there.

However, so far no luck with ordering miners and quite reluctant to wait for Whatsminer M3 March shipment. Plus the Xfers.io is still pending my account verification.  Huh

Once I have my hands on any miner, I will have problem getting the hot air out. So i might as well plan ahead and ask these questions first.

Thanks! Any ideas/suggestions are welcome!

Yes first make sure that you have the right infrastructure.

Windowless office doesn't sound like one, sorry.  Cheesy

And only after you have everything clear and planned out, then it is a good time to order some miners.

These are hard to keep stable unless you have near zero room temp, lots of burned out power supply distributors and power chords, can’t get the temp below 85o Antminers in same room run at 54o

They are a bit cheaper but a bit harder work. Also use a fire proof room, no carpets etc, I can see these power units sparking at some point

Was a big fan of these but moving back to Antminers

How air conditioning won't help? All Datacenters over the world are in closed rooms with air conditioning.

As long you have enough air conditioning power to cool the air, it won't be an issue. I think that a 24000 BTU air conditioning will be enough for 20000W (10 Whatsminer).

In bitcoin mining it is more viable to create a good ventilation than to have a air conditioning solution.

Good intake and good exhaust fans  system.

4 x 20000 = 80000 so how does  24000 cool down  80000?


answer it dont.

a watt is close to 4 btus

around 3.93 IIRC

So a 24000 btc ac  will not do trick for more then 3 x 2000 = 6000 x 4 = 24000

Thinking on that, you're right. You'll just spend the money you'll make in more electricity. But maybe in the case of the friend who have the empty room could be better.

Wow. I'm not smart enough to do this calcs.  Grin

Maybe a 60k BTU (5kw/h * $0.1 (hydro) = $0.5/h * 24 = $12/day) could work.

https://www.cryptocompare.com/mining/calculator/btc?HashingPower=110.5&HashingUnit=TH%2Fs&PowerConsumption=20000&CostPerkWh=0.1

He'll earn $277.63 a day. $12 is nothing compared to it.

My calculations are right?

Testing of the M3 Air conditioned Room 24000BTU AC set to 20 Degrees Celsius.
Staying in South Africa it's summer so its hot now have a Turbine Ventilator in my Mini Farm also with 24000BTU AC.
This method of venting with AC ducting works great. The M3 Temps made no difference with the ducting but venting the heat works great less noisy as well.
All and all would say its an ok miner if the hashrate did not jump a lot would have been great have 4x and the all fluctuate drastically from 11TH/s to 13Th/s+
Do take caution what surface you put the Miner on, the bottom gets just as hot as the whole miner. raised the miner by placing 2x thin planks below each fan.
if you need a budget miner this is great but if you can get an S9 its well worth the extra cash.

P.S. this miner does not work on all mining pools so take caution before buying struggled my ass off to find a popper pool to mine after nicehash.
XNSUB seems to be enabled on the miners but causes wierd hash spikes maybe have to set a manual diff or something can anyone suggest the
recommended difficulty for BCH and BTC. or even suggest the pools you guys are running on would be great im currently at litecoin pool hashrate
seems most stable.

Thanks Guys.

There is no 'official' Bitcoin pool. All of them are independently run. What pool are you thinking of?

Got 9 ordered.  For March batch though. I hope they send early like bitmain has been. Probably not. I'm looking forward to seeing how my new 240 service will handle the added 9.  I'll be at 85%!

The website is live but unfortunately the option to order is not... According to @pangolinminer twitter account M3 March batch was also going to be available today after maintenance, is that still scheduled?

There is now a live countdown on their website. It says that next sales will start in 18 hours 49 minutes and 25 seconds (I tried to time that message perfectly). There is also an announcement that it will happen 2017/12/22 13:30:00, maybe its in Chinese time.

English is not my native. Thx.

I have a fresh M3 but it doesn't work :-(  . . .I plugged it in, it looked liked it connected due to the pools it was already configured with.  I then changed the pool settings, saved and rebooted and that was the end of that.  The device runs, the fans run but the cgminer software doesn't start and you can see that in the device settings.  It simply states "waiting for cgminer software to start".  I left it for up to 20 minutes with no luck.  The pool I'm trying to connect to is the EU based pool for Slushpool.  I made sure that I didn't copy any extra spaces at the end of the "3333"bit. 

I recall the device getting very hot, about 80 degrees and uncomfortable to the touch, then the fans completely slowed at some point and the device eventually settled.  The fans kicked back into gear up to full speed but the device status simply does not populate with any information.

Right at the bottom of the status page, the device shows an error": E011  Slot-0 Zero HS 4500 seconds  Zero HS Warning  6  Thu Dec 7 12:59:42 2017 system-monitor"

Has anyone experienced this?  I have restarted the cgminer by clicking the button and I have rebooted the device, nothing changes.

@Cryptosaf

I tried to help him via pm conversation, hopefully you get it running soon.
Pangolinminer should be able to help you once they are at the office again.


I updated the opening post with the current 'How to order' information.

EDIT:
Update (December 24, 2017):
Pangolinminer is now taking orders through their web shop at their website www.pangolinminer.com
They should have few different shipping time batches for sale during the Christmas time.
The counter at the web shop page indicates that this would happen in December 26, 2017.

11.7 Thash at 2000-2200 watts is a joke these days, I wouldn't use it if it were free.  Piece of crap 28 nm miner.

Still decent for people with cheaper electrical costs and it comes at half the price of a preorder S9. It has its niche and it's selling out almost instantly. Was actually considering buying one of these as I have very cheap electricity.
