Guys,
see first post, I've corrected an error about speeds and put a couple of graphs.
Thanks.

Your terms on shipping are really killing this. Since we have no idea if the data center is going to charge extra for handling, let us use our own labels, or if they even have a discount rate.
But what the hell
I will offer 9@.15BTC each
Hi MCHouston, I've asked Michigan colo your same questions, I'll post their answer as soon as I get it. Thanks. spiccioli |

just to get this auction off the ground:
4 units @ 0.35BTC each, shipped to Toronto
Well, at your previous offer of 1100 USD for 5 units shipping costs could have been included, but at current 0.35 BTC shipping is, as I wrote in first message, to be agreed upon with Michigan-colocation and paid to them. Regards. spiccioli |

|
|
So if this is an auction I assume I can use bid like normal?
9 @ .1 each (I can provide labels)
Sure, in the end the best offer per unit/whole lot wins. spiccioli |

fair price for 1TH/1KW is about $180/ea (since the S5 is 1.2TH/0.6kW for $370)
fair price for 1050W GOLD PSU is about $90/ea
I would be interested in a few units shipping to either Toronto, Canada or Winnipeg, Canada depending what the shipping would look like. Could offer $1100 shipped for 5 units
klondike_bar, they come with their stock PSU, I'm not sure that it is GOLD rated. Shipping to TORONTO, M5A9Z9 CANADA (a random zip) costs around 70 usd with UPS Standard and takes 4 days. spiccioli |

Any estimate for shipping all of them within the USA?
Hi MCHouston, I've used Amazon's declared dimensions and weight http://www.amazon.com/Bitmain-AntMiner-1000-SHA-256-Miner/dp/B00KH9339Oand put them inside UPS calculator and for shipping from Troy, MI to 90008 Los Angeles, CA (just a random destination not too close to Troy, I don't know where ZIP 90008 ends up) I get a shipping cost range, for one unit, which goes from 322 USD for next day in the morning to 72 for a ground expedition lasting 4 days. Just to give you an idea, hope this helps. spiccioli |

Hi fellow miners, I'm auctioning here 9 Bitmain S2 miners. Auction ends Friday, February 5th at midnight 12:00 am UTC. I'd like to sell them as a lot but I reserve the right to sell individual units if I receive good offers. All units have been hosted at Waveform Technology in Troy, Michigan since they were bought. Michigan-colocation (as they're also known here) offers an astounding service but alas at current BTC price/difficulty ratio units cannot be hosted there anymore. So, if you happen to live in an area with cheap electricity this offer is for you. 5 units are hashing at full 1TH/s while 4 are hashing between 800 and 900 GH/s (see below for speeds). Shipping will have to be organized with Michigan-colocation and paid by buyer (I don't know if units can be collected at Michigan-colo's facility, but I can ask if there is some real interest). Escrow by some reputable member of this forum welcome, buyer pays escrow fees, otherwise you pay me and I will authorize Michigan-colo to ship the units. Please post your offers in this thread if possible, PMs will be answered in around 24 hours. Happy auction! spiccioli. ps. If you want to write me, please keep in mind that I live in GMT+1.

My units were hashing on two proxies (slush's proxy code) so that I could switch pool with a single change and have some redundancy. I've plotted their real speed from Jan 1st this year to Jan 15th when they were powered off, these two graphs are made counting accepted shares only, so they show the real speed of the units as seen by the pool. I have to correct my previous statement that 5 units are able to reach 1TH, just 3 are able to reach a full TH, 2 are at 900 GH and the rest at 800-850 GH, I'm sorry for this error. In any case, considering current bids, they're still a steal. First proxy with five units  Second proxy with four  Regards. spiccioli
February 4th, 2015 - some answers from Michigan colo
I've just received an email from Michigan colo with some answers to shipping costs and local pickup: - collection at their facility is an option
- there is no extra charge for handling, they charge 7 USD to schedule a pickup at their facility
- typical costs for shipping in the USA are around 50 USD/box since they have discounted rates from UPS
February 5th, 2015
Clarified auction's end, it is going to end today at 12:00:00 (noon) UTC, see my last post. Sorry for any confusion. spiccioli

Does it mean that by using your multibit.checkpoints file, when I do "Reset blockchain" it only goes as far as 19/11/2014 ? Thanks.
Yeah mate thats what it should do. If it works leave a post here. I'm not sure how far away multibit-hd is but I'd be happy to keep a semi updated checkpoint file available for the guys that want it. After chaning the file and hitting the Reset, multbit started to load all blocks since my first transaction (Dec 2013). It doesnt appear to help :-( It works when you have multiple wallets, you open one, sync it, close it and then open a second one, at this point MultiBit syncs this second wallet from the time its checkpoints file was made. Thanks to esotericizm it now syncs from november 19th last year, so it is a lot faster! spiccioli |

Thank you esotericizm, I'll test it in the coming days. Happy New Year! spiccioli |

Great question! This might solve a long-standing issue for me, too. I've never liked keeping my main wallet open when I shut down the program. I like closing the wallet, then the program. That seems safer to me. But then, when I restart the program (and wait for it to sync) then re-open the wallet, it has to re-sync all over again from about March, like you say -- and that takes forever when you're waiting to do a transaction. I've been told, "Just leave the wallet open when you close the program." And now I do that. But I'm still not comfortable with it.
I don't think there is any problem leaving them open, when you close MultiBit, it closes every open wallet before shutting itself down. The issue remains though and in my case is compound by the fact the I can't have all of them open at the same time or otherwise sync never ends, it keeps resending bloom filters over and over again and it take 30-40 seconds each time it has to recalc them! spiccioli |

Hi Jim,
I'm running Multibit 0.5.18 and I have several wallets
Everytime I open a different one, Multibit syncs it back since March 25th, 2014.
This is not only becoming annoying, but makes using a wallet increasingly slower.
Can you make a new multibit.checkpoints file? Or is there a method to build one?
Regards.

While I don't feel any significant resistance if I hang a wire grill at the same place
I would not leave such a powerfull fan open, it can seriously injure a finger. spiccioli |

So if I can't go faster, let's try to go cheaper I've attached my unit to a Cooler Master V1000 PSU, 80+ gold and around 91% efficient at this load and I've limited chip voltages to 0.665 volts, without touching max watts per board, as per Spoondolies Tech recommendations.  And here what I can get, 1305 GH at 700 W, fan slowed down to 40% and chips nicely warm (intake at 22 because I'm back inside my mom's garage).   I'll leave it hashing at 0.536 J/GH for the time being, or at least until after Christmas time. spiccioli |

Yesterday I made a couple more tests after running it for a week at 1.5 Th and 1000W during the paycoin frenzy    First of all I did try to push it to the maximum, having a 1600 W PSU I though I could go higher than 1.7 Th, but alas I could not. Intake temperature as reported by miner's interface is higher than environment's real one, I was in a 10 ° C as this old analog thermometer shows  but miner's reported temperature was at 16 ° C and increasing  At 1667 GH I was using around 1280 W on a 220V outlet with my Recom M1600 PSU (85% efficient)  1670 GH is as fast as it can go, in a 10 ° C environment, because of thermal throttling by the chips, which were not able to remain below 125C even at 100% fan speed.  In his review johnyj is doing some great mods to better cool all of the chips and so avoid thermal throttling, let's see what he can get. spiccioli |

Made an aluminum block to narrow down the lower channel
Unfortunately the result is worse, temps rose by a couple of degree under same ambient temp, maybe some turbulence made fan spin slower
Nice work johnyj, but instead of putting that aluminum block inside the case, what about simply putting a stripe of tape on the holes on the intake side of the case to block air from entering that space? I'm away from my unit or I'd made this test right now spiccioli |

i like the background stories, these are little snippets of people's lives that we very rarely get to read, it kinda puts a persona behind the usernames. thanks for sharing.
My pleasure! spiccioli |

What concerns me more is that those miners behind him are actually set up for mining; as in not manufacture, but farming...
Does that mean Bitmain is actually doing "burn-in-testing" on the live net too (before selling it to "us")?!?
Its a US farm so its probably on behalf of a customer. How do you know this, I don't think png files store exif GPS data? It is written inside the sell offer. spiccioli |
