Topic: Whatsminer M20 is announced and available for pre-order - page 4. (Read 4298 times)

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


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


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.

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.

yes it is. that opening can do 1x 30 amp 240 volt circuit.

the box fan tosses a lot of cool air at it.

there is no way it can do more then 4800-5000 watts.

right now there is 3400 + 1300 = 4700

I just took a six hour read 5:13 to 11:13

52.56 kwatts
32.39 kwatts
20.17kwatts  in six hours

or

3.36167 kwatts

or

3361.67 watts  which is a little better then  I hoped.           3361.67/68.678 th or     about 48.948 watts a th

that is not as good as my s17  which does 41.98 watts  at 2225/53   but I paid more for the s17

and my power deal is 50-50

so I get 34.349 th vs 26.5 th   at no power cost.  so for me  either one is good

I paid 2048 for this m20  purchased with coins under 5000
I paid 2225 for the s17 purchased with coins at 5300

the prices I paid the m20 was a little better but I got the s17 30 days sooner. So I earned 30 x 26.5 x 0.00003800 = 0.03021 btc at 8000 =

241 usd   so with that adjustment

m20 2048
s17  1984    s17 is 64 dollars better and loses about 8th in hash or 2.20 a day  so in 30 days the m20 is better

but that is with my 50-50 power deal.

Either one now costs more

If you shipped me one today  I would pay close to 3k for 1

this is assuming import duty cost in all examples above

right now the gear is way higher and you have to wait for it.

Right makes sense the PSU is going hard, I think I remember seeing these are using larger fans to cool the miner. Well I may be a while on those numbers, I have been put on delay again with no ship date in sight due to the ongoing issues in HK. In the meantime I will just continue to tweak my planned sound dampening for when this arrives, maybe move the M10's in there early to see how it handles them.

I imagine if you had 3 machines on that door setup you might be in trouble, seems a tight fit to prevent to prevent the backpressure off the door. Is that M10 the PSU issue?

the psu is pushed too hard  so its fan whines very loud.

below is a simple way to exhaust the heat

Your video will be live at: https://youtu.be/Kt7ud68dmSM

it keeps the unit cool and the s9 along side it is cool and the m10  to the far left is dead.  working on some kind of an rma for it.

Nice info so far Phil. I was definitely expecting it to be a little quieter, but without the high pitch it might be more inline with what i was thinking overall.

If mine ever shows i can get readings on the power draw real time. I am still amazed that the LP mode wasn't working as a standard feature - mind you these are demo/engineered units.

it will allow me to do testing in house before I bring to clifton nj

and i will be able to go well over 3000 watts with no issues.

The m20 is in the house doing its tuning

and it is up doing 69 th



Multiple issues abound.
I could not find it on my d-link router. Address of that router is 192.168.0.1  I have 20 pieces of gear on it.

Must be a conflict I moved it to my trendnet router

Address 192.168.10.1

Put a pc on it and found the gear.

other issue is  it has a firmware error for low speed  only runs high speed.

low speed generates error 201 p20 not found in cgminer.

@ frodo can you merge my thread into this one.

https://bitcointalksearch.org/topic/demo-m20-v1-is-on-order-due-may-20th-5126286

i just locked it.

so this gear is loud 80-84 db

not super high pitched but loud.

it only runs full speed.

I had an issue with my router d-link router 192.168.0.1

but my trend net router 192.168.10.1  was fine  as  i only have 1 pc 1 miner 1 router on it  so no conflicts.

seems to run at 68.8 th temps are 72 c

will give a power readout.

very soon.

2.02   kwatts
3.17   kwatts
1.15    kwatts in 20 minutes test  x 3 = 3.45  kwatt or 3,450 watts   so 3450/68900 = 50.07 watts a th.

tired will be shut this off due to noise will do a movie or 2 on it.

This is complex call  to say it is better then the s17 or worse since I don't have working slow speed firmware.

my new  meter does kwatts

I am doing a 1 hour test.

I was at 6.06 kwatts
after 1 hour I am at  9.43 kwatts

that is 3.370  or 3370/68.6 = 49.12 watts a gh  which is close to last nights test of 50.007  watts a th

here is a gui screenshot  68.6th



this is too long of a post

here is a youtube link for unboxing

your video can be found at https://youtu.be/wpyIHm9Z6BE

here it is up and running it is set into a sound proof setup so you do not get to see a good view of it in this video

Just use a metal Junction box, with a flip lid, mount it inside on the flip lid so the meter part shows...done and done.

https://www.surplussales.com/Cab-RacksHardware/encl_2.html



At $15 each. This may work. Just grab'd if off google. Did not check the size. But something like that, I'd just spend the $$ and use by the panel

Would be a way to keep track of whatsminer or other miners in the basement for probably more fun than profit at these prices though

I am back  and still waiting for the gear.

I can confirm philipma1957laptop is an alt I made today.

that meter has a kit




I will build my own case for it down the road.

just made account this as i am not at my pc.

it is a subpanel it has 2x  30amp 240 volt circuits.  my main panel  is 150 amps it was full no room.  so I pulled 1 30amp 240 volt breaker from the big panel put in a 60 amp breaker ran it to the new sub panel with space for 2 breakers.

So I gain 1 circuit it lets me properly run in the garage for the summer.

i used a 6 gauge cable  from the main breaker to  the sub panel.

Do you have a better image or link to the above picture? I assume it is some kinda box that is combo meter and shut off valve?

That would be kinda handy to have, in that I have fewer basement miner units, I may put up, (for giggles) and if so running them thru this box may be prudent...

as not to be mining at 'too much' of a loss (before I can use such to heat this winter) for the dreaded 'summer rates' don't ya know.

Besides, it would look kinda cool next to the basement panel.

later

I have lots of low end kwatt meters that do about 1800-2000 watts.  kill-a-watt will measure to 1800 watts for an hour or two but not 24/7/365

I saw that meter on ebay but I want a meter today and the one I purchased will come today.

It also has a good kit which I will buy later to house it in its own case.

I actually plan to   use the meter

to this panel



to 2 l30r

and measure up to 48-50 amps.

that is a later project

Interesting, everything you read says only up to 125VAC???

http://www.p3international.com/products/p4460.html

P3 Killa watt ez works on my 240V 30A line just fine. We can source them and the cable your want for a package if needed.

Did you see this on eBay? Might save a few bucks if it's a good meter.

https://ebay.to/2wVsX7n

I am sure it will drop low enough to be a non-issue , but mine will come on tuesday and we will check it out.

I can provide a dedicated 30 amp circuit with this cable

https://www.tripplite.com/power-cord-heavy-duty-20a-12awg-12-feet~P040012P30

https://assets.tripplite.com/product-pdfs/en/p040012p30.pdf

this will do the trick for speed testing.

I do suspect  I may run it at  low speed and use this cable

https://www.amazon.com/C20-C19-Power-Cord-IBX-1804-02/dp/B00CFQJ3WI/

with this pdu

https://www.ebay.com/itm/252635-001-HP-24A-200-240-Modular-PDU-Control-Unit-228481-002-Pulled/323472256173?

I ordered  this meter today

https://www.amazon.com/gp/product/B00GMZRXE8/

I will get it same day and should get a good reading on the power this beast will use.

I will use it with this cable

https://www.ebay.com/itm/NEMA-L6-30P-to-C19-Power-Cord-8-ft-20A-250V-12-AWG-Iron-Box-IBX-4943-08M/223394324234?

which I will splice the meter into it.

It will allow me to properly test higher power gear.

like this.

Down the road I will change test bed  to have 2 plugs  and test as much as 2 x 24 = 48  amps at 240 volts.

Low power mode is available on M20S, not exactly sure what it drops power consumption to thou

I can't say for sure. If it's anything like the m10 then there would be a Low Power mode. I should have mine in the next 3 days- I'll update once it's hooked up.

Will you be able to underclock the M20S? My PUD is 16A for the C20 connection.  So at 208V @16A I get 3328W. This is maxing the circuit. If you underclock the M20S that should give it more headroom.

Yea, we should have pre orders open. Still sourced through Pango.
