Topic: M30 vs M50 a short review - page 2. (Read 391 times)

Another pro tip, just mouse hover on the error when viewing the Whatsminer tools and it will tell you what the error means without having to fo to the miner webpage, also, double click on the miner's row takes you to the webpage of the miner.

I would like to thank you for both using my services as well as making the review, I would have loved to see you run both gears at the same place so we can compare temps, fans and power, doing so when each model runs in a different place with different voltage and cooling will not be fair.

Yeah that room has over 40kwatts of gear in it.

WE ARE Waiting for a new panel the panel is 80 years old. been a long wait.

I will need to put some bitmain gear there and move the m30's to the other room.

here is the m50 room it has over 100kwatts of gear.

230v is great, those m50 gears must be running without much effort, anything between 220v and 240v is good, higher is better for PSU, cables and everything else that carries power to the miner, slightly below 220v i would not bother, temprary below 210v is ok, but running steady for long period of time at 203v is something i won't reccomend, so ya sure thing call the electric guy, it is thier JOB to give you proper voltage input since you are paying for it.

@Sledge0001, I have bought and sold hunderds of the m30s, +, ++, various m50 models were sold to my clients, none of them hashed at specs, all run higher which is great and people loved it except for one client who was mad at me because i sold him some 100th m30++ which did 106th and he said his pdu was near full and could not handle the extra 200w per miner lol, luckly he was able to use powerlimit and did not insist on returning , I now have to make everyone aware that I won't be responsible for gears that do slightly higher hashrate than what is on the label.

Seems to me that Whatsminer is good choice in value since they appear to be a bit more stingy with their reporting hashrate when compared to Bitmain.

To me that means the M50 units are tested properly and are sold knowing that they are solid at exceeding their performance specs.

I have 7 x M50's total in the stable and all of them exceed their expected hashrate from the manufacturer.

The majority of the units I have are the 108/110Th/s units and are all pushing over 111 poolside!

I have a single 112/114Th/s unit that's pushing 117Th/s...

And I have a single one of their 118/120Th/s units that is crushing 121-122Th...

Gearing up to roll out quite a few of the 118/120Th units shortly! :~)

that is worth merits.

I am going to check the other building with the m50s now.

other building is 230 and 230.5

need to talk to electrical guy.

Those can be somehow inaccurate since temps inside the farm will differ by a considerable margin depending on the airflow, turbulence, not enough exhaust causing heat to re-enter the miner, not enough intake space and etc.

As you can see the miners are reporting 25-26c while your sensor is reporting 18.4, that's off by nearly 7 degrees, it's always best to check the miner's temp sensor rather than external sensors.

But anyway, temps are still good, and don't worry much about them even if the room heats up, the miner will tune lower and will go into protection mode both on PSU and hashboard levels if temps can't be kept low enough.


That is pretty low, in my previous post I meant to say below 220v, which is the minimum stated by the manufacturer, but I have tested some M30s all the way down to 205v and they ran just fine, even those that threw a voltage error did not seem to bother and just kept going.

I am pretty interested in hearing the compassion part between the M30 and the M50 especially that now the price difference between the two is just about 2$ per th.

A pro tip, going to the Whatsminer Tool and going to display settings, you will find a lot of fun stuff to show like the daily power consumption, also you could exclude a lot of the not-so-important info like the power supply version and all that things that you won't need for daily monitoring, just to keep 4-6 columns that you actually use.

I have sensor push app.

the room is 65 f in and 92 f out

also we have only two of four exhaust fans turned on.

I will check current volts.

ev temp 25 and 26 c which is good.

volts are 202 and 201 need to talk to power guy

Let us check your voltage at the PSU meter, go to whatsminer tool and follow this.

 Settings > display mode > custom > add PowervIn

This will display the voltage at the PSU, yours seems to be below 200v which is why you get that error.

Also, you can add EnvTemp which is vrery useful too.

This gear is stable and runs a lot like the m10 or the m20 or the m50.

I will get access to the m50 and post on it later.



comments  are welcome.

this one is legs  B/C and never drops down

here is the 206 error explained

space

note this machine has an error.

It is my 3 phase leg a sometimes drops low.

so if you are wired a/b or a/c you go to about 200 volts. and get this 206 error.

we are in Clifton NJ and our power grid is nasdaq's back up it is tested 2 times a month and we drop down in volts.

So I got 4 units 2 of each mikeywith helped me acquire them.

M30s first
 As you can see they are very close equal.
 I checked off the two that are the m30s

95 or 96 th and set to 3200 watts.

one pulls 3214 watts and does 96 and change
the other
one pulls 3171 watts and does 95 and change

both do 33 watts and change
