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?

new firmware update for SP10 !

Zvisha you are the Jedi of the bitcoin's manufacturer !

edit : +10 Gh/s with the last update and it seems that the consumption is lower ?

[jtoomim]

Let me ask one: if a July/August SP30 is expected to sustain 4.5TH/s on 240V, what sustained hashrate can I expect from the same device when powered from dual 120V/20A circuits instead?

Mine was getting 4.5 TH/s while it was being tested in Israel. It's now on two separate 120V 20A circuits. Shortly after I received it, I had it running at 4153 GH/s using 2672 W long enough to grab a stats dump, and I think I saw it go up to about 4.2 or 4.3 TH/s before I ran into a bug. This bug limited me to about 3.4 TH/s. Zvi provided a new firmware with a workaround in firmware 2.23 within about 12 hours of me reporting it to him. This firmware has hard-coded limits of 1080W DC and getting 4.0 TH/s (3967 GH/s precisely). Once Zvi releases the actual fixed firmware, I expect to be able to improve my hashrate even farther. I think 4153 GH/s should be pretty straightforward for mine. Mostly, I'm just doing this experimentation on 122V out of curiosity, since I'll have 500 kW of ~250V up within a week or two.

As for the 220/230/240V discussion, all three of those voltages are found in both North America and Europe. My brother's house in Seattle has 115/230V, for example, whereas our datacenter warehouse came with 480V and two indoor dry transformers which provide nominal voltages of 120/240V (which I'm using) and 110/220V (which the other suite uses).

Converting from two 120V outlets on different circuits in a 120/240V split phase system (typical for North America) to one 240V outlet as Adam suggested would be physically possible. However, I have never seen such a device before, and it would be tricky to use properly. Anyway, _{it's probably easier and cheaper to just host your miners with me.}

....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. ...

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.

I tend to agree. Not sure what drew me to this thread since my current hashing power budget is about 80W-120W ("Free" power). The reports of high-noise kind of rule out home/office use as well. My current miner is actually in a relatively sound-proofed room: but that sound-proofing is insulation. Not sure it would dissipate 3000W even if I wanted to try it.

BTW, I would not recommend running 240V to a 120V outlet: the danger is that you may plug something without an auto-switching power supply in there.

Back to topic, what are the updates in the new 1.5.4 firmware for the SP10?

Thanks

Spondoolie-Tech didn't "have" to make the SP30 a pre-order. ... It is the manufactures decision to use your pre-order money for R&D and making the product ...

It was already discussed many times in this thread before. The pre-order money was used for ordering the batches, not for R&D
The 3 months lead time forced us to take pre-orders, because of the amount of $ involved - 10s of $M

As I wrote many times also, I much prefer selling from stock, but it's not an option for us.

Two more issues to consider:

- We know for a fact, after talking with them, that the Chinese manufacturers were dropping prices because of our pre-order price point.
- We don't self mine and we don't compete with our customers. We have 1MW DC in Israel, most of it populated by customers machines.

Hate to repeat myself, but could we please have the change log for the latest 1.5.4 firmware for SP10?

Thank you.

Consider time diff ...
It's early morning in Israel, and Zvisha (probably) worked very late yesterday (today)

Oh, I was hoping you could have some clue

[zvisha]

Come winter, it gets very cold here in the north east, and it's very easy to keep ambient temps of our little (read: 150sqft) farming room down under 10C, even with 20kW of Antminers. Can we expect more than 4.5TH/s if we're on 220V, and with extremely low ambient temps?

Not likely. SP30 has low leakage and proper DC2DC, so you don't see much dependancy on ambient in the range I tested - 25c-35c. But I didn't try them in low temperatures, you ill need to play with AC2DC limits.

Thank you.

It is a fix for a problem I seen on one of the SP10 bought as 2nd hand machine. Not critical.
I recommend to upgrade to the latest, it knows how to handle one more situation.

Note that the hash rate is more expensive the higher you raise the watts.
You can get ~4TH for 2300W, but the next 600W will only provide 0.5Th - much more 'expensive' hash-rate in terms of power.
So I guess for 2500 the system will give about 4.2TH. If you pay 0.15$ per kWT, you still better running 4.5TH (100$ more). If you pay over 0.35c per kWT, you better run 4.2TH.

About $0.022/kWh here, once we get above 200 kW of usage. About $0.04/kWh before that. The SP30's efficiency doesn't enter into my configuration decision calculus yet. Risk of broken equipment does, but the chance of improving the performance of all 68 of our machines with some simple mods largely offsets that.

Thanks! I'll take a look.

Zvi, I'm expecting significant diurnal variations in ambient temperatures in our datacenter. Does minergate take ambient/intake temperature into account at all for determining optimal settings?

Perhaps it would be good to add an adjustable ambient temperature coefficient for some of the major variables, like the PSU power limit. If the thermal shutdown temperature for the PSU is 150°C (what is it actually? I have no idea), and ambient is 20°C, that would be a temperature gradient of 130°C for the PSU's waste heat to flow over. For the sake of easy calculations, let's say the PSU goes into thermal shutdown if you use settings that result in more than 130 W of waste heat being generated in the PSU. That would indicate that the PSU has a thermal resistance to ambient air of 1 W/°C. If you then dropped the ambient air down to 5°C, you would expect to hit thermal shutdown at 145 W instead; if ambient rose to 35°C, then you'd hit shutdown at 115 W. As I understand the limit finding algorithm, you'd end up running your PSU at settings which work in the worst-case scenario (115 W) even during the best-case scenario (145 W) if you saw high-amplitude temperature fluctuations.

Another option might be to first learn what settings work at one ambient temperature, then after that process has completed, create a few separate learning context variable sets (structs or whatever) for different temperature bins, using the original ambient temp settings as a template, and refine the new bins independently. This would probably be significantly harder than simple temperature coefficients.

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).

What price will SP-Tech be declaring on the invoice for Customs ( original purchased price or original minus compensation ).

The invoices will contain the adjusted price i.e. original minus compensation.

I find this argument thoughtless. Those of us who don't own our own homes are often prohibited from making these kinds of modifications.
