Whatsminer M20 is announced and available for pre-order

[Raymond_B]

The model numbers and specs you are posting have me super confused, are you testing an M20 or M20S? The Microbt site shows M20 is 45TH and M20S is 68TH.

the name of the model was changed

as I ordered a demo model

named m20 72th
then named m20s 70th
now named m20s  68th

I have the 68.0 th model prototype/demo

or this one

Whatsminer M20S demo units shipment could be delayed due to Hongkong Labor Strike, we will update once restore.

and you would order it here

https://pangolinminer.com/product/whatsminer-m20-series/      note it reads m20  old name but when you open it you see m20s

so far  I appear to do 3360 watts and 68.6th

on high setting.

low setting generates an error

Code:

]201  p20 not found in cgminer conf

I suspect that is a bad line of code to be fixed later.

If I were the coder in charge I would offer top speed at 65th and low speed at 50th

as I think my unit pushes psu just a bit too hard.

[Raymond_B]

OK, perfect, thank you. I noticed on Microbt's site they list all the LPM firmware as "coming soon"

[philipma1957]

yeah I could tell by the error I got that the code for it{low power mode) was left out or botched.

[Apprentice]

still don't know why they have 2 models with almost the same W but diff THs.

Whatsminer M21S
56Th/s @ 3360W


Whatsminer M20S
68Th/s @ 3260W

[philipma1957]

the 21s is like the bitmain t17  cheaper to buy but not as good as the  s17

the m20s is like the bitmain s17 more costly to buy  but better then the t15

Having run the m20s using close to 3360watts and getting 68.6 th

it is a beast  it reminds me of this scene in the movie " fast and furious "

it is an industrial machine  as it sounds worse then any s-9

Well thats disappointing, i expected to see your video of the M20S not a clip from fast and furious...

But you could do a chrome paint job to the case if that makes you feel better.

[philipma1957]

Yeah  I can only run it until about 11pm as I don't want my neighbors to kill me.

I can run the s-9    24/7/365  and it is not as noisy.

We are waiting for  some power work in Clifton I will bring it up to the bigger farm on monday .

It is a loud beast indeed! (the M20S 68Ths)

I've mined with all kinds of devices but this one was the first one
which made me startle a little during the startup.

Here is a video:
https://mega.nz/#!UgcBhAoY!tXsJnCTid1zHgLzsrEzIoKBQR1u3gPuBGElo-gwaZ8Q

The numbers are looking great,
about 68Ths, 3.4kW

A further review will soon follow..

Nice.

Does your low power option work or do you get error 201?

[HagssFIN]

Doesnt work

[Ambros]

Do you know what's the maximum power that can be drawn from the included PSU?  (I was that this is rated for 3350W, looking for the real number)
Is there any room for overclocking? Given the extremely high efficiency it could be worth it

[HagssFIN]

3350 W is the max. power capacity at the low DC voltage rail.

It is a server grade psu so it can handle the nominal max. power 24/7/365.


I would not necessarily recommend overclocking this.
It is already pretty damn well optimized for max. performance.

[philipma1957]

My opinion for what it is worth is that it pushes the psu too hard  and should be tweaked 5% lower to 65th vs the 68.6 th I am getting> I think the psu would work better doing 3200 or 3100 watts  vs the 3375 I am doing on mine.

I realize that  ac 3375 x .94 =  3173 dc  so it is not maxed .

Oh it is running here you can log in and see it's hash

m20s

I am running the gear in cool spots  right now I moved it out of garage which was 80f  to the small solar array in howell

that is about 60f  so it does not struggle much as temps are easy on it.

I would think that in a 95f room it will struggle and pull more watts.

Looks like 100 unit pricing from pango is displayed. We added a group for july batch with customs support for buyers.

can't find it can you pm link please

[minefarmbuy]

Can't really call it a PM here so I DM'd ya.

Can't say duties help this but will may help 100 or more get some better pricing and worry free customs support on our tax id.

Well I finally received some tracking info and see it as confirmed shipped. Just over a month late but should have it in hand Tuesday, and online that night if I'm lucky. Almost would prefer Wednesday so I'm home but I've found making any changes to my DHL deliveries is to confusing for the local people; at least it's not -30C outside this time around.  

So I finally got my machine in been busy and couldn't do much more than get it hooked up and hashing yesterday. So far so good, I should have my power meter on it this weekend to get some results but the sound was easily dealt with, i'll take readings of that as well.

Things that aren't so good and need to be discussed with Pangolin, it appears they sent me a 65 TH model - little over 10% below advertised spec when i ordered (72) and 3 TH lower than the model I should have received.

[philipma1957]

Do you have a low power option that works?

Does the 65th use 3100 watts vs 3350 watts?

I for one would prefer a unit using 3100 watts with a bit less hash.

3100/208 = 14.9 amps
3350/208 = 16.1 amps

All the cables I have found rate 20/16 amps

Now our power does not drop to 208 it drops to 216

But

3100/ 216= 14.35 amps

3350/ 216 = 15.50 amps. So my unit is here at the moment close to the 16 amp max for 24/7/365 duty.

My second unit was lost at JFK airport I have a postal trace on it but I have very little hope of recovery.

This will represent the most expensive piece of gear ever lost during shipping for me.

Sucks big time.  But shit happens.

[Steamtyme]

I'll check that LP mode tonight and see if it takes. I'll let you know how the power draw is as well, just have to convert the plug ends over. So far I've only hooked it up and let it run to confirm the hashrate, had to go out of town so no time to test anything yet.

Quick update: I have no working LP mode. Same as you noted you can select it but it doesn't work.

Code:

Power detect error, can not find power P20 in config

Power meter is hooked up this morning so far looks like 65 TH at 3180W. I'm going to give it a 24 hour run and I'll do a review write-up like I originally planned - considering it is a different spec machine.
