No, the lab is in Israel. I am actually flying on a 3 day vacation tonight, but we will check this. It's in our interest to provide as much hashing as possible to every voltage.

The equipment hashes 25% less than expected, consumes 30% more than expected, promised units not yet delivered - what to do next?  ...go on a 3 day vacation! 

I wouldn't advertise that.  People waiting are going crazy while the lead guy sits on the beach blowing dope and drinking vodka.

Collider, jtoomim, Roadsress or anyone with the early machines:

Please post your statistics and whether you achieved sustained ~4.5TH at 208-220V (please post your voltage) and what was the speed at 110/120V if applicable (I assume 4.1Th). Thanks.

I now have 4 machines here running on 120V. One is personally mine. The other three belong to wanna4fun, our first customer. (He gave me permission to mention him.)

I have mine set up to exceed Zvi's recommendations for power for the PSUs, and it's getting about 4080 GH/s. I had it getting 4170 GH/s for a while, but that was with a different airflow configuration that allowed me to use more power. The PSUs are currently limited at 1125 W each. It uses the Emerson PSUs. This machine sustained about 4.5 TH/s for 24 hours while in the Spondoolies DC for testing, as I mentioned previously. It's using 2.2.28, because I found it easier to exceed Zvi's recommendations and controls with this version.

The three from my customer are capped at 1100W, as per Zvi's recommendations. They're each hashing stably at around 3950 GH/s. Currently, I'm seeing 3923.69 GH/s, 3951.675 GH/s, and 3982.555 GH/s. These three are all running 2.2.35.

For reference, I'm also getting 1377 GH/s on my April SP10 operating under similar conditions. It's showing much greater temperature sensitivity than the SP30s. In the SP10s performance graph, I can see a slow downward trend in performance as the room it's in heated up, then an upward trend from last night around sunset as the room cooled off again. I see no similar trends in my SP30 graphs. However, the SP30s are in a different room from the SP10, so this isn't a conclusive test.

Intake temperatures are currently pretty high, as I've got them all crowded in the break room of our office space while we finish up our DC. Temperature does seem to affect the propensity of my miner's PSUs to overheat and go into thermal shutdown, but it doesn't seem to affect hashrate directly, at least on 120V. As long as your PSUs are stable at that power output, your hashrate on 120V should be pretty consistent and independent of temperature. According to my observations so far, I think temperature and airflow might make up to 120W (60W per PSU) of a difference in the amount of power you can let your PSUs supply before going into thermal shutdown.

We energized our transformer for the first time today. It turns out we have the option of supplying about 258V, 249V, or a few other lesser voltages. I'm opting for 258V for now. That voltage will probably drop a little bit once we start to get close to our full load capacity. SP30s and most other machines are rated for a voltage up to 264V. We also got to test one of our evaporative coolers and exhaust fans today. It looks like they'll work very nicely.

I should be able to start migrating our machines over to 258V later today. I'll probably have some statistics on 258V to share tomorrow.

This simply isn't the advertised (after adjustment) 4.5TH.  WTF?  Is spondoolies trying to lower the rate still further?  6.5Th -> 6.0TH -> 5.5TH -> 4.5Th -> 4.0TH.  Where does this stop?

4 is about 60% of 6.5.  That sucks tremendously.  That is not a simple engineering estimation error.  That is a major defect.

Product was advertised at 5.4Th/s. The 6Th/s was an added bonus and not available for long and for many customers. SP10 had a drop in hashrate on 110V so it was expected to be the same for SP30. The machine can do 4.5Th/s, but you just need to supply it the proper power.

This is at 120V. Everybody who has been paying attention has known for ages that Spondoolies equipment suffers a performance penalty on 100-120V. This was not at all a surprise. Zvi and Guy have warned that 120V users will se a large performance penalty, and they strongly recommend using 200+V. Performance for these machines should go to around 4.5 TH/s once I get them on 200+V.

Power supplies have lower efficiency and lower capacity when run on lower voltages. Spondoolies's machines operate at or near the limit of their power supplies' performance, which means that running on 120V slows down the machines.

OK, enjoy your time off.

In the past I have dealt with "electromagnetic compatibility" labs that were targeting "new economy" vendors hopeful on entering the rich US market. Those vendors were from e.g. Malaysia Technology Super Corridor, where scam relied in large part on the language barrier. This clearly isn't the case with your company, because everyone seems to fluent in English.

Don't be lazy and go and research it. Youi should never believe what people say but always make an effort to research things yourself.  Most of people who keep up to date with bitcon news know that Bitfury has just opened another massive DC. Can't be arsed pointing you to articles you can easily google up yourself. Have you got 350 posts in your counter by ask pointless questions? (rethorical question)

I already spend far too much time researching this stuff.

The DC in the article you linked was deployed 2 weeks ago and I've seen no mention of the exact amount of PH they can fit in it.

Guy mentioned that a new bitfury DC was deployed in Iceland and I was hoping you had some info on that.

Spondoolies's machines operate at or near the limit of their power supplies' performance, which means that running on 120V slows down the machines.

This seems to be a very short-sighted cost-cutting measure. As someone who has mined for many years, running PSUs 24/7 at 100% capacity is never a good idea.

Actually they run them over 110% capacity   source ZVI somewhere in this thread

I have been trying to purchase the SP-30 6TH/s miner and have actually written with Gadi a few times, then,, poof, vanished.  Now the SP-30's are 4.5TH/s and we have been trying to figure out the difference but cannot reach anyone at Spondoolies-tech.  We were going to purchase between 4 & 6 miners but could not talk with anyone.  Has anyone else had this problem?  Doing the "due diligence" I thought I had found the best company to do business with, now???  No answers.
Thanks to anyone,

I think they just got another round of chips in, so im sure everyone is hands on deck to get the SP30's put together, tested, and out the door to us. The miners you are looking to buy appear to be available on their website for September Batch, there is enough information in this thread that you can easily decide if you are willing to purchase or not, the only reason i can see youd want to talk directly to them is for a discount.. now in my opinion, getting miners into our hungry hands and on time is more important than offering you a discount for possibly 6 miners in September (they have not even come up with a finalized compensation plan, they obviously can't discount before that happens) . Things will slow down eventually and they will become the great forum presence they have always been. Hang in there brotha.

Spondoolies is in full production mode at the moment and support requests with less priority could take a little longer than expected.

You will get very fast replys if you need to change your shipping address (e.g to your hosting site) or need help with one of your already owned units (you can also post here first and someone will likely help you).

sales@ should work fine.

Just include stuff like the order id and obviously the new shipping address in the email.

The 6TH/s SP-30's are vapour-ware as I understand it. The 4.5TH/s version actually exists.
