Just to avoid any misunderstandings, if you had the curiosity to open your electrical panel in a generic US residential home, this is how it should look like if you take down the cover:



The image shows 120Volt lines and 240volt lines. Both circuits have ground wire. Each 120V and 240V require two wires to complete circuit. 120V requires 1 hot and 1 neutral. 240V requires 2 hots. Some 240V lines have additional neutral wire. Neutral is not absolutely necessary to complete a 240V circuit. Some 240V lines have white and black instead of red and black.

To avoid burning the place down, follow the rules below about the wire sizes:



With this in mind, here's how one should wire their 250V sockets depending on the type of wires running to your mining location from your electrical panel (-2 wire or -3 wire) ..



or



You definitely have this setup already if your house is built after 1970, since most of the driers and ovens are using 240V in your house. Older houses may be the exceptions I'm going to be trolled on.

As always, if you're not sure what you're doing, get a licensed electrician. Just bear in mind you don't need a dedicated 240V circuit if everything you have is ONE/TWO SP30.

If anyone is interested, I can build to order CSA certified power distribution (sub) panels (metered or un-metered).

Yeah this is how my house looks , the issue though is not the adding of adtionaly 240 v circuts, they also need to be run up and down the wall of my unfinished basement , to the spot where i host my miners near a vented wall

So i got this email from SP-TECH, its nice that you have decided to honor the original hosting deal, in my case though I have decided to stick to my original plan and host it myself , i plan to run it at 4TH max to keep the PSU's at 2500WAttsI might get come 240 circuits placed as well next week and since it gets cold here around sept(only one month away) i can use forced air cooling and probably pay alot less in electricity costs going forward.  I figure by spring next year the unit will already be unprofitable to run in any case unless btc prices really shoot up.

of course this being the case I would prefer my unit shipped sooner than later as well: do we have a firm ship date on these units yet ?
 Also how any new details on how I will get compensated for the reduced hash rate ?  I paid by bank wire, but I would be fine with a pay-pal re-reimbursement or something even though I would prefer a coupon for a nice discount on October gear.

thanks again.

Please clarify how my comment was stupid.

It is stupid because it shows a complete lack of understanding of life experiences different from your own.
There are many reasons people rent instead of buy. In the USA, they could be compromised financially by medical expenses due to serious illness and sold their home to pay the bills, they could be recently divorced and have lost assets to the SO, they could be young and yet to get into the property racket, they could be priced out of the market due to work circumstances, they could have moved recently new a new part of the country and be renting before they buy, they could be waiting for the inevitable property crash in San Deigo to get in cheap, they could ...

There are a million and one obvious reasons why people might rent instead of buy other than not having prioritized buying a home.
Your remark was stupid because you haven't figured this out. My guess is that you are young white, affluent, middle class and live in North America and haven't travelled much.

There are alot of reasons people rent instead of buy.  They are usually not logical. I could put a valid argument for each example you gave.  I can't say that I have traveled outside the usa at all, but you can't say that people who have 6k worth of mining equipment are disadvantaged.  I bought my first house for less than that.  

By no means do I have a poor perspective on people in the usa.  In the us anyone can get a house loan, and again the loan payment and insurance will always be less than rent.  If for some reason the market crashes and they have cheaper prices, you can walk away without penalty. Situations in other 1st world countries are probably similar. For the 3rd world countries, they barely have electricity and internet, I don't think this discussion really applies to them.

I am not a part of GB, so just a matter of factual accuracy; wasn't the hosting deal $290 and not $310/mo, but maybe there are some savings in shipping or setup, so the 6 mo total does not change.

Why don't you focus on the mining discussion and avoid brining your personal opinions into it regarding how someone tends to want to live. If you want to get into a conversation about personal choices in home ownership take it elsewhere.

[zvisha]

The miner turned on:
67DB

This remark gets very easily overlooked without the pictures which were earlier in the message.
I can bet it was fun measuring the DB level with the unit initially turned off

Yes, we had to be very quiet

I think the $290/mo was for the 2500W. After the upgrade announcement to 6Th/s the power consumption went up to 2700W so that's why the cost per month jumped to $310.

You are indeed one ignorant person. You know shit about life, particularly outside the block you live in.

When you refer to a 3rd world country, take a note, that there are all beauties of modern civilization in there. Maybe even more, than in US. The key difference from developed countries is, that the middle class is almost disappeared in 3rd world countries and the rich are getting even more wealthy by abusing and enslaving of those in poverty. Believe me, you will not trust your vision, if you see those castles engraved in gold the rich people in developing countries live in. Their vehicles, also covered in gold or other precious metals. And army of slaves, behind them...

This is in Brazil, for example:


Regarding renting or buying a house, have you considered about the fact, that 30% of US population has a bad credit history or a bankruptcy, hence they can not get a mortgage loan? Educate yourself a bit, before making those hilarious statements...

wow, this looks almost like a setup from the "Soylent Green" or "Elysium"

[jtoomim]

What you saying about learning context is an option - but the SW does not work with learning context - not in voltage/freq scaling, and not in AC2DC scaling. In voltage/freq scaling I recalibrate every voltage change - because temperature difference can cause difference in results and there are too many contexts (voltage/heat)., and in AC2DC the user can set it to 1380W if he wants to recalibrate.

I don't want to restart system too often, it will cause too many questions without any real value (imo).

The issue that I was raising is that temperatures in my DC are expected to fluctuate a lot (nearly as much as the outside temps) within a single day. Reconfiguring a miner for each time of the day is not a practical solution. Using settings that work in the worst case is a practical solution, but it's not optimal. I don't know that

I haven't seen any of my ASICs go above 85°C yet. Is performance on 200+V systems usually thermally throttled on the ASIC level or limited by PSU capacity, or is it limited by something else?

The temperature coefficient algorithm I suggested shouldn't require any additional restarts. You can think of the current firmware as being equivalent to using a tempco of 0%/°C for all of the variables. A non-zero value could be hard- or soft-coded into the firmware. If the tempco being used in the firmware is smaller than the physically accurate value, then the algorithm would converge on a configuration that is nearly optimal for the hottest conditions experienced but suboptimal for the coldest conditions experienced. If the tempco used is higher than the physically accurate value, then optimal for cold conditions but suboptimal for hot. I think it's unlikely that 0%/°C is the optimal value for all of those values, but it's possible that the optimal value is close enough to 0%/°C that it's not worth your time to code it. My quick-and-dirty estimate suggests it would, at least if either PSU heat rejection or thermal throttling is the bottleneck on performance.

You said that temperature didn't make a difference between 25°C and 35°C. I'm curious how you tested that.

P.S.: Can you guys take the rent vs. own argument to another thread, please?

^^^ TL;DR

Why don't you code it up and submit a pull request ?

The thing I find most surprising is that ST is still pricing the Sept. SP30 machines at $3895 + shipping.  For the same price, I can buy 4+ TH of S3 machines and mine 4 - 5 BTC before the SP30 starts mining. To be competitive, the SP30 should be priced no more than 2.5 BTC

Yea, I'm confused about the pricing as well. I think they must pay a premium in raw materials or pay a shitload of money to get them built or something to have a premium price like that. They need to start ordering cheap ass China materials and build with that, lowering the overall price making the end product more appealing to potential customers. Yea, their rigs are rock solid and made like tanks but in my opinion maybe their purchasing decisions could be a little better.

Simply put, they are over built for a system with an expected lifetime of 6 - 9 months.

Thank you for letting me know you are the first to reach the limit of 28nm Sha256 engineering.

Thank you again.

RockerBox is certainly not the limit of 28nm SHA256 engineering.
PickAxe our 3rd gen is also 28nm. The fact that we're using exactly the same process means one less production risk for us. We gained a lot from the issue we encountered with the first wafers lots of RockerBox.
I believe that there is still a lot room for improvement.

I would have an interest in buying a PickAxe if you allowed cc or paypal and If you did not do it as a long preorder.  2 weeks or less and  I would be in.

 Same as I asked to use with the sp30 and the sp10  as I still believe you sell the best gear. 

In the same boat, unfortunately SP-Tech wants to keep their sales model as pre-order only. Manufactures have the ability to change that and sell out of stock but choose not to because of the less risk to them. All the risk then shifts to the buyer and we see what happens. Please, don't get me wrong, and from previous posts, I think SP-Tech is probably one of the best makers of mining hardware around and I do look forward and eager to see what is on the horizon and future. I think they did the best they could with what they had and believe me, they didn't like the results and specs of their SP30 just as much as the customer's didn't.

[s1gs3gv]

Yea, when do the SP50 pre-orders open ?

[opentoe]

I don't think trolls will ever stop, because if you go to their message history you see that they are active on 1-3 HW manufacturers posts, trying to demotivate people, and that's all they do. And they didn't ever buy miners from us. For example, s1gs3 writes only in "Alpha Technology Litecoin (Scrypt) ASIC Miner Order Batch 1 Now!" and in this thread, almost every day, and telling how great Antminers are. I don't have anything against antminer, but how often do you see us going to other vendors technical forums, disturbing operation?

And at this point EVERY new person coming to this thread asking relevant question about noise, voltage, rate, warranty, delivery  or whatever will get into conversation with a troll before I even wake up.

I will do my best to convince Guy to ban people who disturb operation from this thread - I think it will be less damaging for our clients then keeping them here. He thinks they will "settle" down, but I don't see think that people should be allowed here to disturb the operation.


And even after I blocked them, I see them in quoted boxes if someone replies to them :/

You guys should throw up your own forum. It is very easy to install since you already have your domain/website setup and really doesn't take anytime to mange or run it. Then you can really have a dedicated area for support relevant to your products instead of this one huge long thread that takes forever to find info and catch up on daily. Some of the most popular forum software is free. You guys could at least give that a try to get away from all the BS and trolls. And if you do get a forum up and running, one suggestion, don't turn into a moderator police officer. Some companies forums are horrible since they delete every post they disagree with and don't like. As long as the content is of a serious nature and respectful the post should stay. Good luck.

....And statements that assert that substandard performance at 110 volts is not a problem because customers can always host in a datacenter instead of running their machines in a home or office environment are disingenuous. ...

At 3kW, you won't be running on a standard home/office circuit anyway. (North-American plugs are generally limited to 12-15 amps of continuous draw (1320W-1650W at 110V, power factor of 1.0)

Edit: I suppose you can hook it up in the kitchen where the outlets generally have two branches (The SP30 does have two supplies).

Adding a 240 volt circuit to most houses is trivial and cheap. If you can afford 4K for a mining device, you can afford another 50-200 dollars for a new circuit or, worst case, a new panel with a new circuit. I find this argument disengenuous. Calling out a company for missing their target is fine and dandy. From what I've seen, Spondoolies has acknowledged that they made some errors and are working to rectify it. But bitching about a circuit or two is just plain trolling. This is high school level stuff.

To those of you who don't know how to do it and/or are afraid to, an electrician is not THAT expensive. It boggles me how people are willing to spend a small fortune on these devices and then bitch because they have to spend a pittance more to make their house compatible with the CLEARLY commercial grade equipment.

Here in NJ electricians are VERY expensive. I have a 100amp panel which is almost full and wanted to add a sub panel and a couple 240V circuits. I actually got two quotes. One was for $1200 and the other was $950. Installing new circuits you sometimes need to break down the sheet rock and do a lot of other things that just add to the cost. Once the electrician leaves then you need to do some sheet rock work, spackling, painting, etc. It adds up.

For  product with a life-span of a maximum 9 months, you can't afford to build it on stock. Look at the biostar 24GH board. They agree it was a trial run, but they came almost 1 year late. If it was an investment to be paid back, it's completely dead. On the other hand, there is a step between pre-orders and stock. It's called build-to-order .. similar with what you do in a restaurant  Sometimes the server takes your steak back because it's "not according to spec", but most of the time, they get it right and everyone is happy with the service.

The technology has to mature for this to happen .. or at least to have a couple of 28nm designs which are systematically improved, a ton of chips taken out the foundries every batch and with a demand not this high to eat all the output (decent 1000 units batch) in a month "on trust" (pre-orders). Eventually, we'll see custom configurations, unique setups which will closely meet the customer demands if they're going to be sold.

Can someone explain how the September batch 2 SP30s (and I assume other batches) have 2x 1200 watt PSUs and draws 3000 watts at the wall?

http://www.spondoolies-tech.com/products/sp30-yukon-september-batch-2

$3895 plus shipping will be well over $4000 for 4.5TH/s in September, mid/late September since it is batch #2 is a pretty high price no?

By well over you mean what price? $10k?

Not that much. Instead of well over, maybe medium rare. Specifically it would be $4195, which I'll mark up to $4200. You don't think that's a little high for 4.5TH/s delivered in mid September? And I'm not trying to argue, being serious. I guess prices and money is all ones perspective since everyone has their own value of money. I work hard long days for my money, so I value every dollar. I'm not cheap or frugal, but I do try to get the best price on something I can, if I can.
