I got this to work by clearing out the included message history.  Start with a blank slate and include just the last two message history.

I use the pcie or as you say vga.

here are my  4 running as I type

I've gotten this problem a lot in the past too. I think if you send the same message from different email addresses, then Google will just think you've got several email addresses that are working in collusion to send spam. Try sending an email to a specific person at Spondoolies (e.g. [email protected] or barbara@) instead of one of their shared email addresses, as the individuals' addresses aren't mediated by Google Groups. You should also forward the error along to stas@, as AFAIK it's his job to make sure this works.

Try info@ and support@ .. from info@ you get an automated reply back. Here your message looks like SPAM and Google Groups rejects it  ..

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?

Thanks!

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!

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!

Hey, does anybody have the same problem when sending email to sales@ ?

Edit: cc of the same email sent to a person at spond seems to go through fine, so problem seems to be at sales@ address

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

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.

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.

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.

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.

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.

 

 

 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 .    

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 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`.

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.
