More newer homes in the US now have 20 amp and they can be put in easily if you do not have it.
Make sure that the wiring is 12g or 10 g to be safe.
I added 200 amp for my mining setups in two phases.  10x 20 amp breakers.
It works well for the SP10 and should work fine for the SP30 if using two separate circuits.

You could run them in a 120V environment if you had access to 2x 20 Amp circuits instead of the 15 Amp ones. This may be something you could have an electrician put in if you really wanted to, but I feel where you're coming from, that you expected 1 thing and now have to go out of your way to make it work in your own environment at a possible extra expense.

Agree...Sorry...

First time I asked very civil...did NOT get the answer...That's why I tried more "pushy"...

I do NOT expect the true answer...

...but the "twisting" ...or "no answer" is still good source of information...hiding the "truth" ...right...  

Cheers,

EDIT...:

Exactly like SP-Tech...

what was the latest order number shipped?

Your question was also very aggressively phrased. There's no need for sexual innuendo. Can we keep our discourse civil, please? Also, please trim your quotations.

This has been discussed several times. 1200W is the minimum rated capacity for the DC output of the power supplies. Since they're about 91% efficient, they use 9.8% more power than they deliver. Also, after extensive testing and discussion with the power supply manufacturers, Spondoolies has concluded that it is safe to run each PSU at an output capped at 1360 W, which translates to input of around 1494 W.


I'm running into a similar issue at the DC I'm building, where the power jump from 2750W to 3000W might push me over the edge of the amount of current each circuit can supply. My approach to dealing with this issue will probably be to boost the voltage from 240V to around 254V by switching the taps around on my transformers. 254V is probably better anyway. I doubt that would be an option for you, though.

You don't have to run it at that power level. If you use the Quiet mode in the firmware, you'll get a max voltage for the ASICs of 642 mV instead of 750 mV. I would guess that would reduce your J/GH by a factor of about (642^2 / 750^2) = 0.73 to about 0.47 J/GH, and reduce performance by a factor of about 642./750 = 0.856 to around 3.8 TH/s at 1900 W. At least, that's what would probably happen if your ASICs were actually using the 750 mV max voltage, which they're likely not. Guy says 0.55 J/GH when downclocked: https://bitcointalksearch.org/topic/m.8091352

By the way, you can see the voltages and power limits in the Spondoolies Minepeon code: https://github.com/Spondoolies-Tech/minepeon/commit/f9d5535c3e525bdede299773c9d0b5f26d85fd5b

Hey RoadStress...

I am NOT trying to get involved in any debate / fighting over your posted "information"... or ...etc...

BUT...obviously you are VERY biased in favor of SP-Tech...

My questions was very clear...What is your COMPENSATION for doing these "bent-overs"...

Nothing else...

I am not on their payroll. I just have plenty of spare time and I'm using it to lurk the forums. This is the second (or third?) remark that I'm "furiously jumping" people who have critical remarks of SP-Tech and again I don't see anything wrong in my quoted post. I did read my post again and I see nothing wrong. I may be pissed that people are not reading the last posts or at least the last 1-2 pages before posting and they are asking questions that were answered just a couple of posts above, but besides that I just offered information.

Please tell me what from my quote makes you think that I jumped furiously on bitcoinbearhk because of his critical remarks. I'm a bit confused right now.

RoadStress...are you already on SP-Tech payroll...

I am just wondering, because you are so furiously jumping on everybody with critical remarks of SP-Tech...that is kind of strange...

Or maybe 1% commission of your group buy in miners...like 3-4 SP30 reward...I guess...

...and don't try to bash me...Just tell us the truth..."it will set you free"...

I actually lucked out - got a bunch of S3s just for the fun of it - and I am totally shocked how good they are.  Rock solid.  Just running, running, running.  Making BTC.  I can't believe it.  I thought that was just more Chinese shit.  Not true.  I got fucked by BFL (American), I got fucked by KnC (Sweden), and I got fucked by Spondoolies (Jews).  But I didn't get fucked by the Chinese.  What I got from the Chinese is pure, solid, rocking hash power for a very cheap price.  

I guess the pendulum swings.  Who'd have predicted fucked up shitty engineering from Americans, Swedish and Jews, with kick ass reliable engineering from the Chinese?  Not me.  The world turns.

By the way, I sent a new order for S3s this week - 10X my old order.  Fuck KnC, fuck BFL, and fuck SpondTech - they are all lying bullshitters who can't engineer a hashing machine.  AntMiner rules!

Spondoolies thinks it is no big deal they missed the target by a mile.  However, all those who carefully planned out a target to profit on pretty thin margins - got royally fucked.  Now RoadStress is running around saying: 'just have it hosted'.  Well, many miners didn't want to pay the service charge of hosting.  They wanted to rely on what Spondoolies said and host themselves.  They believe in the power spec.  They believed in the hashing spec.  Which would have worked - except one thing: spondoolies didn't know what the fuck they were doing despite telling everyone: "Seriously, we know what we are doing."  They also said: "you can take that uncertainty out of the equation".  So we all did.  Now, its not Spondoolies getting fucked - we are getting fucked.  Spondoolies still has the same amount of money as if they delivered the full spec.  They didn't.  Now everyone is scrambling to do what they can with the new parameters.  Changing from a planed site to a hosted site is not trivial.  This is a real impact on peoples plans.  RoadStress spent a shitload of time in other thread bashing the fuck out of other projects.  Now that SP30 project is all fucked up - he says: you should not be using these at home anyway.  Well, if the specs were correct, they'd actually work on 120V @ 20 amp.  But as we were all stupid suckers and believed the bravado from Spondoolies - and fully did not expect the serious shortcoming which is the SP30 underperforming machine - abortion of engineering - we don't know what we are doing - we are now fucked looking for new arrangement to try to break even.  

There is only one solution: Spondoolies must make a seriously kickass gen3 machine and offer it to previous buyers at cost.  It is the only way they will come right.  The compensation package is silly for the reasons spelled out by many above which say that power cost the big let down.  

SP50 is the only serious fair recourse.  If Spondoolies wants everyone to be happy, they will go back to work, and build the best machine ever and let loyal customers into the earliest release.  

Anything else is just about as lame as KnC.  

Notice how Spondoolies is acting just like KnC now.  KnC released a few Neptunes and now they say: "Neptune shipped on time".  It didn't.  They shipped a few on time, many thousands are not shipped and won't be for a long time.  Now, Spondoolies released a few SP30s and they claim: "we shipped on time".  However, they haven't shipped a serious number of them - just a few.  Spondoolies is looking more like KnC everyday.

yeah if I had know about the s3s coming online and that SP-TECH would no hit the 5-6TH number I would have def gone with a bunch of s3s  
I'll be looking for a hosting company when my SP30 arrives

https://bitcointalksearch.org/topic/confused-about-power-for-spondoolies-sp30-yukon-718831 Read here for more information about the PSUs.

As for you exceeding the supply of 1 socket I just posted a link above where you can find a place to host your miner probably with cheaper power costs than yours.

Also if a small part fails the whole machine won't fail so you don't need to worry about it. I am sure that each chip is independent and if one fails the others can continue running without problems. The SP10 units have 192 chips in them organized in chains of 8 chips for a total of 24 chains. Collider has a unit where a chain of 8 chips failed, but he is still getting over 1.4Th/s with that unit. Each SP30 miner has 30 chips in it.

Power Supply: 2 x 1200W
Power Consumption: 3000W

 

WTF

By the way, I don't like the idea of 3000W for 1 machine ... I live in 13A@220V zone, meaning 3000W JUST exceeded the supply of 1 socket ... thus the machine will need 2 sockets, wasting the socket slot.

Also, putting too much into 1 machine means when a small part in it fails, the whole machine fails.  Where as if I split into, say, 10 x S3, it's more robust, more deployable, and flexible.

The sp30 numbers are not on paper any more they are finazlised, and the price is lower than what it was before :  that being said just due to the fact that s3's are available today that would be the route to go, who the F knows what diff will be in end of Sept when the sept/oct batch of sp30's ship.  If you have an SP30 in July Aug Batch you might as well see how much BTC you can make before Sept , At current Diff they shuld make you about 6-7 BTC before end of sept which is pretty much close to ROI.  Its a ok deal but of course no where as near a GREAT deal it would have been if SP-TECH had met their original estimates.

SP30 Yukon September Batch 2 has a published hash rate of 4.5Th/s +-5%. Stop spreading lies and check their official product page and if you look a few post earlier you will see the live proof of the 4.5Th/s hashrate so it's not numbers on paper. Happy mining!

I actually already did this.  S3s are running very strong.  You'd be a fool to buy the SP30 which has a 'published' hash rate far different from the delivered hash rate.  That's just plain old betting.  With S3 - you get what is written on the tin.  Big difference.  Buying unicorn days are over.  Promises, promises.

Buy the S3 - they are actual hardware which works.  Numbers on paper are just silly.  Ain't never going to happen.

Who's hosting it at a decent rate? ST?

I never stated anything about you buying or not miners. It was obvious that you don't have all the facts and I just presented them to you.It has nothing to do with having or not a stake in SP-Tech hardware. Where is the harm in giving you free information?

For home mining users it is OK to allow API access for all over the LAN but it may not be a good idea to allow access to cgminer API from anywhere if you use hosting ...

You can use a ssh connection to your SP10/SP30 and open a tunnel to remote address "-L 4028:localhost:4028" if you want to do remote monitoring but on same time keep cgminer setup with API access only from localhost.

I use this trick to remotely monitor my SP10 located in a data-center.
