Yes, it's because you're on 208V. Notice that your machine is configured to use 1360W max per PSU, but the software is artificially limiting it to 1250W. That's because these PSUs are less efficient (i.e. generate more heat) on lower voltages, so they can't deliver as much power, so Zvi hard-limited them in order to reduce the chance of PSU failure. Spondoolies hasn't done much testing with 208V, so they don't know what the PSU limits should be, but they know 1250 is safe. If you want to try to squeeze more performance out of it, you can bypass the 1250W limit with

Code:

echo 1 > /etc/mg_ignore_110_fcc

Just make sure to reduce your PSU limits in the Settings page first. My suspicion is you'll be able to get about 1280W to 1330W out of those PSUs at that voltage, but I've never tried. 1360W is probably too high.

Yet wierdly on my SP30's I was getting between 1330 and 1360 on the same PSU's and the same power circuit. I wonder if the SP31's have more conservative limits on the PSU's I thought they would have less because the claimed TH output was higher needing more power to get there etc.

Update:
Upgraded to 2.5.33 and now the bottom PSU runs at 1360 but the top is stuck at 1250 still, Hashrate nearly 4.7TH

Going to manually set top PSU at 1330 and see if it sticks.

(Top and bottom being how they are shown in the interface and asic stats)

1330 didn't work, top still lim=1250, wierd.

philipma1957:  Ok thank you, now i´m going to see if it works, been 1 hour running now! but i made some cool drawings for a cooling system, going to check tomorrow what the material cost and if it could be realistic

I have 4 units and 3 s-3's I use winter weather and a garage door


a mover's blanket to muffle sound and the open garage door for heat removal




I am running 5000 watts and 7.7th in the garage temps are 89 f



I can stack 1 more sp20 and 1 more s-3



20 inch box fan helps cool gear.

I noticed that when you place an order at SPT, there is some space where you can enter discount coupons.
Are they really offering discount coupons ?
I just bought 2 SP20, I would buy 2 more if they would offer me some discount coupons

They have done in the past, mainly if the units didn't perform to spec or is late shipping. We've also had an existing customer coupon before as well.

I'm also pretty sure that if you buy a big enough order that you will get a discount code.

But this isn't Bitmain, and there are good reasons why not

yeah coupons are rare.  but the diff sticking around at 40 and coin staying at 370 usd is far far far better then a coupon.

Zvi - Could I get a little help on a support ticket for an RMA on a failed PSU. Order#1827  The RMA request seems to have stalled a little. It was originally initiated on December 2nd.

I have it hosted at a facility and the tech at the center reports that the PSU smoked and is showing amber/orange light. The tech has pulled power, waited 5 minutes and reseated, swapped PSU to bottom slot and top to bottom, but essentially the power supply is being reported as smoked.  I put an email into Spondoolies support a few days back and they asked for remote session and I have forwarded along the request to the hosting facilities tech and he has emailed screen shots from the system with 50% hash rates showing and the description of smoked PCB components smell emanating from the system when power is applied.

The tech is more than willing to do a Skype session for the customer (me) in order to satisfy RMA requirements if needed.

Thanks for the help.  I love the products and all of my other Spondoolies miners are minting new bitcoins like crazy!!

It looks like I'm not alone. My failed PSU (on Nov 27) does not have any lights on though. As usual, patience will solve all issues. Just a note for the impatient .. Zvi said earlier in this post that the SP3X units are looking for for a customized PSU firmware and the ebay sourced ones (even the same make and model) will not work.

I can not monitor RMA procedures. I only approve them, then I mail Barbara that the RMA is approved. It is up to you to contact her and close details for shipping, dates etc`.

Your limit of 1250 is because your voltage is under 218V. If you want to force more, you can use the fcc_disable flag people mentioned here  - note that that operation is not covered by our warranty (!!!) - that is stretching the PSU manufacturers recommendation.

 so that psu has a 1250 watt limit from 110 volts to 218 volts?

is this the psu?

  If it is you are really pushing beyond it limits at anything over 1200 watts.   that is the spec sheet above.  If I owned it I would not use more then 1050 watts on a 120 volt setup and I would use 1200 watts max on a 220 volt setup.

   I don't understand why you don't simply tell people  that the high setting are like driving your car at 150 KPH or 90MPH  yeah you can do it but it is not that safe and burns a shit load more gas.  If you drive at 100 KPH or 60 MPH it is easy and the gas mileage is better.
    I you were really clear about this you would have less people hurting the gear they own.  

Just like the sp20  yeah I can get  mine to do 1725gh  with the fans at 100 and using an evga 1600 p2 psu with a garage door open my power at the kwatt plug is 1300 watts.

 so 1300/1725 = .75 gh

right now I am doing   1328 gh  and 720 watts or     720/ 1328 =  .542 watts per gh  

you really should make that clear    to people .

No, the PSU does not have a 1250 limit. It has different specifications correlated with the corresponding AC voltage range. The SP3X programming imposes limits, which can be overridden. The override voids the warranty though, if the supply voltage drops below 218V and the PSU is stressed over the acceptable limits.

You might be interested in the best efficiency .. but not everyone is. "free electricity" locations, and/or hosted environments care more about mining stability than performance.  If you can make the unit run stable at top output .. there's the setting some other people might be interested in.

 

[raskul]

i can almost hear the busy hands back to work in the shipping section of SP-Tech with the parcel tape and the boxes.

1 x SP20 and 1 x SP31 pleeeeeease.

 

SP31? Thought you'd get a SP35?

almost the same thing isn't it?
my principle: i never buy batch one. i never have and never will. if that means in this instance i get 500GH/s less, so be it.
i'm cautious, that's all.

okay I read the spec sheet very carefully and I have run plenty of psu's past spec's but as I read the spec sheet from the psu company if you run 1250 watts draw you are exceeding the psu's warranty limits.

Now this means in order to run to the max gh on the sp31 you must be voiding the psu's warranty numbers.

to me spondoolies  advertisment for the sp31 is not clear enough for overclocker's.


now I am using this pdf as my guide

https://www.artesyn.com/power/assets/ds1200_ds_1219707774.pdf

and it looks like this is the psu in the sp31.

i get that I can go beyond its rating.  I just think that the spondoolies advert is not clear enough to say doing that is like speeding down a highway far beyond the posted speed limits.

 Personally I am only going to buy sp20's I am at the game of max efficiency .

If you have a farm with good cooling and want to run the gear beyond spec I am fine with that.
I just think the add makes you think you can get 4.7 th or more  within the psu's spec's .  I would like to see if anyone is running their machine at 4.7th and 2300 watts or even 2400 watts. or if you can show me where in the pdf it reads that these psus can do 1250 watts 24/7/365

I read 12 volts 100 amps max out put  so 2 are 2400watts max rating   or 1200 each.

So while you may crank the fuck out of the sp31 and pull 2600 watts and get your 4.7th you have voided the psu warranty. to do it.

That's a generic datasheet, and you don't have the one for the PSU version the units are shipped with.
The PSU's shipped from the SPT have special firmware, and were a custom batch of DS1200-3-002. Please find the correct datasheet for reference. When you power the unit at 220V 50Hz, the PSU limits are different than when you power it at 110V 60Hz. Higher voltage means generally less heat .. I was reading here repeatedly that 1360W output when the unit is powered at 220V+ is the spec limit.

The SP3x units have a self-adjusting mechanism, not present in SP20. That is because the software in the SP3x unit "talks" with the PSU and changes parameters at run-time. The override, lets those parameters be changed irrespective of the PSU supply voltage, which may drive the unit outside the spec'd ranges. With your SP20, the power supply is "dumb" and there's no serial communication between the PSU and the unit. That means, that your power supply does not adapt to the required power draw like the Emerson/Murata does in a SP3x.

Moreover,  the product was initial designed and tested for Israel/Europe power supply voltages and spec'd as such (where ~220V is common).  You're looking at the unit from the situation you're in, using 110V in the average north american household. Hence, the situation is different and maybe that's why (i guess) it is not clear enough for you.

it is fully clear now .. if you go back just a bit  post wise you will see I ask the exact make and model of the psu .  now that you mention that the psu is not a stock -generic emerson 1200 and is cabable of 1360watts at 240 volts I will stand down.

Yes, it's because you're on 208V. Notice that your machine is configured to use 1360W max per PSU, but the software is artificially limiting it to 1250W. That's because these PSUs are less efficient (i.e. generate more heat) on lower voltages, so they can't deliver as much power, so Zvi hard-limited them in order to reduce the chance of PSU failure. Spondoolies hasn't done much testing with 208V, so they don't know what the PSU limits should be, but they know 1250 is safe. If you want to try to squeeze more performance out of it, you can bypass the 1250W limit with

Code:

echo 1 > /etc/mg_ignore_110_fcc

Just make sure to reduce your PSU limits in the Settings page first. My suspicion is you'll be able to get about 1280W to 1330W out of those PSUs at that voltage, but I've never tried. 1360W is probably too high.

Yet wierdly on my SP30's I was getting between 1330 and 1360 on the same PSU's and the same power circuit. I wonder if the SP31's have more conservative limits on the PSU's I thought they would have less because the claimed TH output was higher needing more power to get there etc.

Update:
Upgraded to 2.5.33 and now the bottom PSU runs at 1360 but the top is stuck at 1250 still, Hashrate nearly 4.7TH

Going to manually set top PSU at 1330 and see if it sticks.

(Top and bottom being how they are shown in the interface and asic stats)

1330 didn't work, top still lim=1250, wierd.

Your limit of 1250 is because your voltage is under 218V. If you want to force more, you can use the fcc_disable flag people mentioned here  - note that that operation is not covered by our warranty (!!!) - that is stretching the PSU manufacturers recommendation.

I understand the limits etc but why is one PSU going to 1360 and the other stuck at 1250?

philipma1957: Units are running fine now thank you, around 33 degree and getting 1.28th/z mining rate, i use EVGA 1300 do you use SATA inputs on the psu or VGA? i will work on getting those units work 100% as i bought them for that reason, i like your garage! hope you have good neighbours that tolerate the noises!

I am picking up a EVHC Supernova G2 1300 for my SP20. I'll send in my results when Amazon drops off the PSU next week!

Without voltages on the two power supplies no one can say for sure. if one power supply has 217V and the other 218V they can behave like that.
An 1-2V between power supplies can happen due to bad contacts (i.e. higher resistance), loose plug etc.  What voltages are on your dashboard?
