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?

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.

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 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

DESCRIPTION     ADDITIONAL INFORMATION     REVIEWS (0)      FAQ (6)
Weight   12.5 kg
Hashrate   
68 Th/s (+-5%)
Power Consumption   
3260W (+-10%) @ 68 Th/s
Dimensions   
390mm(L) x 155mm(W) x 240mm(H)
Algorithm   
SHA-256
Working Temperature   
-5℃ ~ 40℃
Warranty

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.

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

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

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 "

https://www.youtube.com/watch?v=WtnTZSJndPc

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.

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. Cheesy

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?

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

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.

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

http://ckpool.org/users/16yLHLoeyuCLPMXkVpC3gyrRYvwRGwjKJr

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.

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.  Grin

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.
