Not that I don't like Spondoolies, but I have yet to get 1.4T out of any of my non-spondoolies hosted miners, maybe 1.2T.

Switch on 208-240V.

That's why I said my spondoolies hosted miners hash at 1.4T because they are on 208v-240V. But here in America, it is common to run off of 120v. Now, everything is fine if I run it all in the datacenter, but what if the hosting fee becomes too much based on BTC prices and I just want to take them back and put them in some back room at the office? As in it makes a small margin of profit running them myself without hosting, but pay hosting fees wouldn't be profit anymore at that point. Maybe everyone else doesn't think this way or have this concern...

While others may not have the concern, I was also asking this same type of information about the SP30s a few months ago. We were excited to hear about the product, but I didn't end up recommending it to my company (and others interested in it) because they couldn't tell me the hash on 120v which I thought was strange. They said it could operate on 120v, but could not disclose hash rate to me. Honestly, I also had in mind that antminer will come out with an S4 based on their S3 design. I don't want to go around explaining to people who bought these that they have to take them out of the datacenter, but can't run them anywhere except if they have 208V-240V service.

240V is easy to install in offices/homes that have 2-phase service. 208V is also very common in almost all office buildings that have thier own 600V->120/208 transformer, though there may not be wiring installed for it.

Its common knowledge that power supplies are more efficient and capable of higher outputs when running at 200V or higher, and I personally have converted all my operating hardware to run at 213V for this reason. Paying a few hundred to install the wiring and outlets will pay off in the long run from that increase in efficiency 9and in the case of SP10s, the additional hashrate)
