@Zvisha

Is there another, more powerfull power supply with the same pin arrangement?

Not that we are aware of. AC2DC is the limiting factor of this machine.

There is this:
http://minersource.net/products/delta-dps2000w-server-power-supply
164A Maximum @ 220v.

The question is whether the pin setup is compatible to the PSUs normally shipped within the sp30.

It would obviously not be feasable to attach an adapter (that doesn´t yet exist) to a PSU (that will then no longer fit into the miner housing)

I read on Dogie's SP30 setup guide that the SP30s come with "either 2x Emerson DS1200 or Murata D1U3CS-1300F-12 server PSUs with 34 pin outputs". I found Murata has a 2200w 1U server PSU with 34 pin connector. Could be compatible? But they are not cheap like the Delta...

I though the ASICS are at near max power using the 3000WAT , would you not risk frying them with far more juice than is optimal ?

Based on a statement earlier by Zvisha, "AC2DC is the limiting factor of this machine." I interpreted this as the Power Supply is the limiting factor for the SP30. So I thought maybe they choose the PSUs to use based on cost, not on maximizing performance. A business decision, can't spend more on parts that the final sale price allows. There's also the heat dissipation of the cooling design to consider. I would be curious to know how the hash rate ramps up with more power?

The SW will not work with PSUs it does not recognise on I2C, but that is easy to fix - look at ac2dc.c and ac2dc.h miner-gate code and add your PSU, and compile miner_gate.
Regarding the connectors etc` I have no idea.
Regarding warranty - it will void the warranty.
Regarding heat - the system can handle more heat, especially in cold ambient.
DC2DC also has some head-room in this revision, but maybe not in next revisions of SP30.
The ASIC voltage will have to move higher to the 0.71-0.73 volt area, so you will loose about 10%-20% efficiency.

I would guess that at 4KW one might be able to reach 5.2TH+ in cold room in current corner. Again, there is no warranty on this, and I would not do it and if you burn your house it's not on us

although I am somewhat disappointed you paid 'mucho" for the sp30...I was under the impression you were 'SuperMan"
getting equipment for free from your hardware guides and reviews

Even the guy who writes the software that almost all mining equipment in existence uses and depends on hardly ever gets free hardware, even though he returns the favour with ongoing driver support, though he did get an SP10 which he was grateful for.

I think this is very sad.   Manufacturers need to 'man up' and take care of con and kano.

They probably get free stuff  once in a while and plus they were in the bitcoin game alot earlier than most enough with the pity parade they probable have a decent BTC portfolio.  I write open source software myself and I never expect a handout I do it in my spare time because I like to code..  and ..

most of the code i write and sometimes make money off of is stuff I needed for myself anyways and just decided to share it since it solves a problem for me and others if they didn't do it someone else would have.

they do good work yes but come on now

Thanks. My point was not about asking for more stuff. I was pointing out it would be a little hypocritical for the hardware manufacturers to gladly give away hardware for the sake of a review which may affect the objectivity of the reviewer, while not supporting the developer who wrote the software they depend on. Fortunately neither of the parties involved here suffer from that as Dogie's reviews remain objective in my opinion, and Spondoolies offered me an SP10.

As for writing free software, I actually put aside and sacrifice some time that I used to work professionally to continue working on cgminer (and other bitcoin software projects) turning it into a part time job, though I have continued to try and incentivise the maintenance of all my projects as free software by charging less for paid code when the source remains with an open license such as GPL, or simply maintaining/updating the existing driver for a once off donation. The core cgminer code I continue developing for free. Driver code I find it hard to write for free when it's used to allow a hardware manufacturer to make bucketloads of profit. I also get paid as much as possible in bitcoin since ultimately I'm here to help the bitcoin ecosphere as much as I'm here to get paid. Yes I'm bitcoin-operated as someone once called me, but only for certain aspects of what I spend time coding.

ckolivas, I'll give you 6 kW of free hosting with us for as long as we're in business. If you have use for a dedicated server on a 100 Mbit/s symmetrical fiber link, we could probably provide that for you too, as long as you're careful about security and do your own sysadmining and are okay with uptime in the 99%-99.9% range.

Edit: As long as we're in business and you are actively maintaining cgminer and contributing to the community.

Thanks for the generous offer. I have no need for that at the moment but I appreciate the offer.

[Biodom]

Questions to SPtech (Zvi) or anyone else at SPT or btctalk:
1. If Sp-30 is connected for 6 days to 240V, then switched to 120V for a day, then again 6 days on 240V with cycles repeating in perpetuum, how exactly it would affect it's "learned" behavior. Could this even be done?
2. Is throwing the off switch the best way to switch the miner off or it is better to be do so in gui?

[jtoomim]

Super, thanks, I just don't know about 122V. Typically, it is 115-118V, but i checked my house, and it is, indeed, 121.5-121.8V.

Current performance for mine on 122V is 4190 GH/s as reported by miner_gate_arm.

Different buildings are different. Measure each one when every last few % matters. The SP30 in my office typically reports that it's being fed with 122 or 123V.

It turns out that I had been running my SP30 on one 15A circuit and one 20A circuit. We only discovered this when Eric tried to make coffee and the breaker tripped. I was drawing 1376 W, or 11.28 amps. The coffee maker is rated for up to 650 W, or 5.33 amps, making a total of around 17.5 amps on a 15 amp circuit.

This doesn't mean you will always be able to get full performance out of a pair of 15A circuits, but if your voltage is on the high end of the 110-125V spectrum, and if your breaker panel is in a cool room (mine is), you may be able to get away with it. Hooray!

But you'll lose around 300 or 400 GHs of hashrate for being on 120V. Awww....

If your SP30 trips the 15 A circuit breaker when it's configured for full performance, it's very easy to reconfigure it so that it uses a little less power and doesn't trip the breaker. You just change the PSU wattage limit to a lower value. It's even possible to configure each power supply independently, so you could run one PSU on a 20 A circuit at maximum power and the other PSU on a 15 A circuit at (e.g.) 95% max power. Currently, for example, I have my top PSU capped to 1190 W of DC output and my bottom PSU capped to 1170 W of DC output, since the one I have in the bottom seems to overheat more easily.

As for the toggling power systems question: worst case, when you switch back to 230V, you can reset the learning algorithm by changing the power supply power cap.

And as for using the off switch to shut the miner off: there is none. There's also no "off" button on the web UI. As far as I know, you're supposed to just unplug it. Don't worry about corrupting the filesystem; the main one is mounted read-only, which means that corruption due to sudden power loss isn't possible on it. The non-volatile file system only contains configuration data, and is almost never written to, and can be easily recreated.

I'd recommend against doing this unless you are 100% sure what you're doing.

The fluids you are using can only be used for single phase cooling which is less than optimal. (Might as well just use mineral oil)

With single phase you miss out on the density, efficiency, and cooling capacity that you would get with 2 phase.

There are really no significant benefits for using single phase immersion cooling. You still need pumps/fans and it's even less efficient than air cooling (without an AC).

I agree, you'll be more efficient (regarding the amount of $ you wanna spend) if you build a wind tunnel.

Question about the SP30 power supplies: do the SP30 units ship with power cords, or is that up to the customer to provide? If the customer is to provide the cables, what is the plug type on the SP30 PSUs? From the images it appears to be a standard C13/C14 coupler, but can anyone confirm? I haven't been able to find that information on the website.

Power extension cords are provided, but the customer needs to buy their own power cord for the socket.

You could use such a cord: IEC320 C13 to NEMA 5-15P SJT 13A

You will basically have to see what kind of outlet you are using and adjust your wall end of the power cord accordingly.

If you have two cables lying around that can power a standard desktop computer in your country (with one end as C13 -- http://en.wikipedia.org/wiki/IEC_60320#C13.2FC14_coupler), you'll be fine. Spondoolies provides cables with C14 (which couples with C13) on one end and whatever your PSUs need on the other (C13 or C19).

[jtoomim]

I agree, you'll be more efficient (regarding the amount of $ you wanna spend) if you build a wind tunnel.

As someone who is almost done building a wind tunnel for hosting around 150 SP30s, I agree. Unless you're buying mining hardware that comes without a heatsink and fan, you'll find it much cheaper to pass the heat from the ASIC to the heatsink to the air instead of from the ASIC to some expensive dielectric liquid to the heatsink to the air.

What hardware are you NOT interested in. The reason I ask is that I have good bit of hardware that I have recently pulled from service for lack of space and would be willing to send some your way if you are interested. For example, do you have access to cheap electricity or are you only interested in very efficient hardware? I have hardware, coolers, PSUs and would be happy to send some stuff your way as a gesture of appreciation.

Questions to SPtech (Zvi) or anyone else at SPT or btctalk:
1. If Sp-30 is connected for 6 days to 240V, then switched to 120V for a day, then again 6 days on 240V with cycles repeating in perpetuum, how exactly it would affect it's "learned" behavior. Could this even be done?
2. Is throwing the off switch the best way to switch the miner off or it is better to be do so in gui?

It should be fine, in 110V the unit should not 'learn'.
You can always 'delete' learning by setting PSU limit back to 1360 watt in case it did - the unit will learn again.
You can also disable learning by setting unit to safe number like 1300 watt.
