Sorry for the repeated question SP TECH, but I need to make a decision.
I have 208V power (three phase 460 transformed to 208V). Your post about SP30 having a programmed cutoff at 210, is that a hard number? Will 208V see lower results? If so, how much lower? I can re-tap each of the transformer windings to get it up to 220V, but there is a cost to that and I need to figure out if it is worth it.
Zvisha will reply on Sunday. 208 is a bit low, and might have some small performance impact (~2%) - it really depends on exact voltage. We will investigate next week to see if we can improve that. My Units are not showing any noticeable impact on 208, Im happy to let you remote in and play with the settings if that will help  Is 208V the closest you'll get if you have a 3 phase supply? You ever get any problems with other components? |

You get 208V on 3 phase Y (wye) setup. The 240V 3 phase is usually a Delta setup. Chances are your commercial service is a 208v wye service, which is the most common 3 phase transformer configuration. A 240v delta transformer configuration, which is not as common, is in place so it uses only 2 transformers for a three phase system, where a wye setup would need 3 transformers. Older neighborhoods use 120/240 Delta 3 phase systems. Two phases are 120V to ground. One phase is about 200 volts to ground (wild leg). All phases are 240 between them. Newer neighborhoods (post mid 60s) use 208V. One way to accommodate a secondary (voltage) Delta connection is to get Three Single Phase transformers and connect them in a Wye/Delta configuration. Adding a transformer is not an easy feat for most of the non-licensed guys .. and they might void insurance / contracts. Definitely not the average DIY gig. |

You ever get any problems with other components? If you are in the USA and have 460V 3 phase it will most likely be 208V off each leg (120 X 1.73 = 208V). The transformers are much more common and much cheaper. You can have an electrician re tap the windings to get it to 220V in each transformer but you have to decide if that is really worth it. |

I'm on a 3-phase supply, and our machines are getting 254V right now. Yesterday and the day before, they were getting 259V-263V, but I decided that was a little too close to the limit of what the PSUs are rated for, so we turned it down a notch. It depends on what kind of transformers you buy, and what electricians you employ. Many transformers have taps you can use to adjust voltages. Many electricians will only let you use the taps to produce voltages as close to what's written on the transformer nameplate as possible. |

It doesn't matter what voltage you've got - you've got no machine to plug into that voltage. Spondoolies didn't deliver.
Thank you Spondoolies Tech for helping me earn more BTC/day today than I did 11 months ago despite the huge difficulty difference! |

Do you suggest I built my sp30s myself? If so, I am really talented and should rightfully earn lots of money. Congratulations, you just made the 2nd place on my ignore list. |

nice in btc mining I think sometimes better to just wait (but its hard ) Also, every spondoolies miner until October is sold out, as it seems to be a very popular product So yes, unfortunately some more waiting is required (and I don´t know whether spondoolies will open the batch soon or wait to confirm specs) |

I did meet Joshua Zipkin in Amsterdam and Hong Kong conferences. I've met many more involved in the industry. Joshua was suppose to come to the cancelled Inside Bitcoin TLV at the end of July. Anyone interested in our ASICs is welcome to contact sales@ The lead time is 3 months due to the huge demand for TSMC 28nm allocations. Guy |

Just some truisms penned by some Jewish Bulgarian Freemason Gimp is all. Like I said, if Joshua Zipkin is in any way connected with Spondolies-Tech, I suggest getting in line to receive a refund ASAP. S-T needs to go on record and state that such WILL NEVER be the case, otherwise their brand is trashed. I have no qualms with S-T at this penning, but sure as hell WILL make a helluva lot of noise if Josh Zipkin is in any way connected to these folks. This fucker is bad news across the board for Bitcoin and should be stopped at all expense. From what I've read, Josh is tied up with Dragon miner as well, so that brand will become dead in the water is such is the case. |

Guy Spondoolies-Tech/Guy, I assume this is the normal industry folks meeting industry folks. However if not what influence does Joshua Zipkin have on your company ? Anyways you have a good thing going do not let this worm spoil your apple. You are well aware of BFL's reputation by now. |
