Last update for this week I think,
Quakefiend420 paid for his units, mail sent to Michigan colo to inform them.
Thanks.
spiccioli
ps. klondike_bar and adased I'll be offline till Sunday evening, if you send me a payment between now and Sunday evening I'll acknowledge it as soon as I'm back online.
I sent my 0.4BTc about 2 hours ago, and just emailed waveform |

sp20 will go down to 10$ but s2 will not because of the psu  Can the PSU be even used as a PSU with a computer? Or is it a special PSU with only +12V outputs. it should be a 1050W gold ATX raidmax PSU. I thought these had Enermaxes in them? I think they had both but when you are done with mining can you simply hook it up to a computer or were the molex, sata, ATX plugs all removed? Seems like it would make a pretty good power supply one day. Platinum rated my mistake - it is an enermax. as far as i recall its a regular ATX PSU but a lot of the peripheral cables are not included. It uses 4 modular PCIe connectors, and there is a cluster of cables that are not modular (includes the 24pin, an 8pin, a pair of PCIe for sure, i dont know if theres any molex). Its gold-rated, not platinum-rated, btw however, if you found a similar enermax modular PSU the cables would work with one-another. |

^The SP20 is about 2x longer than it is wide or tall, and works well. the back chips run a little warmer but are still at an acceptable temperature

Current firmware version: 2.6.12 shutdown button should have an yes and cancel question, not directly shutdown!
what can i do about this:
LOOP[0] OFF TO:0 (test serial failed or something)
0: disabled (serial problem)
1: disabled (serial problem)
I have a unit like that - i switched the two serial cables around and the issue moved to loop [2]. The issue therefore is my serial cable and not the hashing board. you might want to see if spondoolies will allow you to open the unit (may void warranty) to try reseating or swapping the ribbon cables. |

thanks for the uber fast reply -i wish more companies had the same quality service..
so i followed your instructions, and i assumed by resetting while powered off you meant plug out and plug in again each board? thats what i did anyways and apparently that did the trick!
Im still puzzled about what did this? my unit does not move whatsoever so I do not understand how come plugging out and back solves anything? or is it a software bug that made a board not working and a manual intervention was required?
the contacts are usually 'springy' so if for ay reason they stick and/or the board shift slightly, the connection may be lost. reseating helps get a new tight mating on the connectors |

For everybody that won. Are you guys going escrow or no? This is my first time actually buying anything over the internet. Don't know the best way to handle the deal?
In my opinion: escrow. Even though spiccioli is a legendary member, I believe escrow should always be used. for a fairly small price like this i dont think escrow is reall required (I generally reserve it for users with <100 posts or when dealing with >1BTC) I am not using escrow for myself, but would be happy to act as escrow agent to any other users who are deadset on it. Id ask 0.015BTC/unit as my fee, and would release payment to spiccoli once tracking shows you received the item. sp20 will go down to 10$ but s2 will not because of the psu Can the PSU be even used as a PSU with a computer? Or is it a special PSU with only +12V outputs. it should be a 1050W gold ATX raidmax PSU. |

^I think you are making a trivial issue into a major product fault that it isnt.
The Sp20 is already leading-edge for efficiency, and while theres a little space to improve efficiency with a little bit finer tuning processes, it might only be by 0.02-0.04w/GH

klondike_bar 2*800GH@.20
please reach an agreement between you and let me know.

done. Im sending a PM now to see what we can do about shipping cost/method |

just got an SP20 that was producing serial connection errors (not i2c) in loop 0 and would not hash. reseating the cables did not solve the problem.
turns out swapping the serial ribbon cables moved the error over to loop 2 - so the unit works! I just need a new ribbon cable for it. (@spondoolies? I emailed benny already - hopefully i can get a replacement to recover the missing 25% of the unit)

Ok, no winning bid for the whole lot, all bids for the whole lot are way lower than bids for some units, so we have this:  These are the bids and the units (and I hope I've not made errors here as I did with time zones ...) I'm not sure about klondike_bar since he put lower bids after a while, so if his higher bid is still valid, he won the first 4 units, followed by adaseb with 2 and blackheart13 with 3. Otherwise, we have adaseb with 2 units, blackheart13 with 4, adaseb again with 1 and klondike_bar with 2. adaseb bids have an OR between them, I'm not sure he wants just one for each speed or 1 overall, in which case things change again and we have adaseb with 1 unit, blackheart13 with 4, klondike_bar with 3 at .20 and 1 at .17 Please klondike_bar and adaseb tell me what is your intention. As soon as we know klondike_bar's and adaseb's answer I'll ask winners to send me a private message with Name and Surname, so that I can forward it to Michigan colo with the number of units won (faster units will go to higher bidders). I'll then send you, through a PM message, a bitcoin address where you can pay me, after I get your payment I'll authorize Michigan colo to ship the units. Thanks. spiccioli looking at the list, my understanding is that the winning bids are based from the bottom upwards, something like this (my first skim of the list to try and cluster bids by user and desired unit speed): adaseb 2@0.27 (specified for 1TH units) blackheart 4@0.25adaseb 1@0.25 (specified for <1TH units) klondike 3@0.20 (specified for 1TH units) klondike 2@0.17 (for <1TH units) quakefiend 5@0.16going back over that in a bit more detail to try and sort out the different speeds 1TH units (3 available) 900GH units (2 available) 800-850GH units (4 available) adaseb 2@0.26 blackheart 2@0.25 adaseb 1@0.25blackheart 1@0.25 blackheart 1@0.25 klondike 2@0.17if the "dutch auction" style is used, the list likely simplifies as: 1TH units (3 available) 900GH units (2 available) 800-850GH units (4 available) adaseb 2@0.23 blackheart 2@0.21 adaseb 1@0.19blackheart 1@0.22 blackheart 1@0.18 klondike 2@0.17obviously things are complicated slightly by the fact that the auction was effectively 3 different categories ps: my bid of 0.35/ea was if shipping was included. obviously its not so im paying the shipping atop my bid prices. |

So you changed the end of the auction last minute to be earlier while I was asleep? I think you kind of screwed yourself as I probably wasn't the only one who was going to wait until near the end to place a final bid...
I'll take however many units I managed to get at .16 though.
EDIT: and if anyone backs out of theirs, I'll take more at .2 as well.
ps. yes, new they were not cheap, like any other money-printing machine since the first asic was made. +1. I remember paying $1250 (iirc) for a september-batch 25GH bitfury started kit. Its now worth <$20 (if you dont consider the raspberry pi that came with it)[quote author=quakefiend420 link=topic=943558.msg10367144#msg10367144 date=1423152712] So you changed the end of the auction last minute to be earlier while I was asleep?

[/quote] If i actually had the leading bids on 7 units, I'd be happy to transfer 2 of them to you - 5 units was my target (I had expected a bit more price war up to 0.25-0.3/unit by the auction end), and i only have so much BTC to cover shipping. |

Shipping to Canada is crazy expensive but using 48617 sample zip code to my address in Canada.
18x18x7, 40lb is $86.05 CAD = ~ 69 USD
So i'll bid
1X1.0TH @ 0.30 BTC
or
1X0.9TH @ 0.27 BTC
or
1X0.8TH @ 0.25 BTC
I just need 1 unit because I have no idea how loud these things will be in my apartment.
where are you in Canada? If its in the Toronto area I am willing to share a shipment with you (might bring costs down slightly) regarding bids, as far as i can tell ^adaseb is in the lead with 1@0.25-0.30, followed by myself with 7@0.16-0.20, and quakefield with 1@0.16I wish. I am way in the far west coast in Alberta. Maybe if you buy more then one unit you can have mine shipped to you and then forward one to Alberta. We can split the shipping and customs differences. Having an Antminer S1 shipped across Canada is around $20 or so. So maybe this S2 might not be much more. unfortunately it would be really expensive. itd cost about the same to send it to me, and then another $50 to ship it several provinces over |

I see 2.6.12 is now available so am downloading it to see whats new. hopefully some further abilities are added to scheduling
EDIT: 2.6.12 made my system think its an SP10 and cant start mining, the fan revvs up and down every few seconds
EDIT 2: went to change back firmware, clicked manula selection, my only options are 1.5.8 and 1.5.10. The Sp20 now seems to think its an SP10 - what do i do?
EDIT 3: used SSH, typed "echo SP2x > /model_id; echo SP20 > /model_name;" and was able to get the device to download the 2.6.12 again, this time operational
2.6.12: seems like theres a wifi function (requires dongle, presumably in the system's USB port). no visible changes or improvements to scheduling though. For that reason im curious to know how changes to the /etc/mg_custom/mode are implemented. Is a reboot required, or just restarting the minergate process?
seems like it could be easy to create a cron task that simply copies different mg_custom_mode(day) and mg_custom_mode(night) files to the actual mg_custom_mode and then re-initiates the miner. It would allow better fan control and precision tuning the voltages and wattage limits for each schedule, rather than just the max voltages
a bit confusing... is that custom day/night your mod or did it come with V2.6.12? 2.6.12 doesnt add anything to the scheduler, it seems to add only the ability to use a wifi dongle my above posts about custom crontab are not part of the newest FW, and should work just fine in 2.6.1 and possibly much earlier firmwares |

New bid:
I cover the shipping to canada (and the duties on arrival) at the (approximate) rate you provided on all the below bids:
3x1.0TH @ 0.20BTC ea
2x0.9TH @ 0.17BTC ea
2x0.8TH @ 0.16BTC ea
I would suggest bidding go in this format, otherwise highest bids and down get the miners in order of performance.

my new suggestion for crontab control that implements a daytime mode from 7am-6pm on workdays to coincide with the local electricity rates:
00 07 * * 1-5 cp -rf /etc/mg_custom_mode_day /etc/mg_custom_mode && logger "daymode" && /usr/local/bin/spond-manager restart
00 18 * * 1-5 cp -rf /etc/mg_custom_mode_night /etc/mg_custom_mode && logger "nightmode" && /usr/local/bin/spond-manager restart
mg_custom_mode_day: FAN:4 VS0:630 VS1:630 VS2:630 VS3:630 VMAX:660 AC0:165 AC1:165 AC2:165 AC3:160 DC_AMP:170
mg_custom_mode_night: FAN:50 VS0:680 VS1:680 VS2:680 VS3:670 VMAX:710 AC0:230 AC1:230 AC2:230 AC3:220 DC_AMP:170
EDIT: tried it out, and realised that even though the miner is in EST, the crontab is based on UTC. I had to bump both times forward 5hrs (ie 12 and 23) to trigger at the correct times. System spun up the fans for a few seconds to implement the changes, then continued to mine with the new fan/voltage/wattage settings in place (no reboot required)
IMO this might be more useful for anyone who wants more complex scheduling.
update: changed 'echo' to 'logger' presumably this will properly write "daymode"/"nightmode" to the log files when the change occurs. SP-T support clarified a reboot isnt required, so the above commands should work fine. (it was suggested that changing ACx isnt necessary though, i guess because ideally it will be set to whatever the PSU limitations are, rather than desired power draw at each mode)
this is neat , I need to modify my sp20s to use these settings , I dont have anything backed up though not sure you need to back anything up. my process: 1) ssh in with root/root 2) "vi /etc/mg_custom_mode_day" 3) copy the above settings, then in the ssh vi editer press "i" (enters the insert mode) then right click (this is how to paste in ssh), then adjust as required. 4) press 'esc' (leave edit mode), type ":wq" (saves and quits) 5) repeat steps 2-4 but with "vi /etc/mg_custom_mode_night" and your nighttime settings 6) "crontab -e" (enters cron file) 7) below the pre-configured jobs, and above the "## voltage start" line (thats where the webUI scheduler puts its jobs), press enter to create a new line  copy the cron lines above, press "i" for insert mode, and paste with right-click. adjust as required (remember its UTC, and look up how to set cron times if you need help) 9) press esc to stop the insert mode, then type ":wq" to save and exit. the cronjobs will now be set, close the SSH note: if you mess up inserting text, use ":q!" to quit without saving. re-open the file and try again. what i need now is an easy way to copy these settings to multiple machines on the same network, and I am not 100% sure if the cronjobs will persist after a firmware update |

PSU A PSU B
b1 b2 b1 b2 b1 b2
S5 S5 S5
Each PSU powers their own S5, then shares an S5 by each powering a blade.
hopefully this clarifies it a bit so people dont plug both PSUs into the sockets on a single blade |
|
|

How loud are these things compared to an S3 ?
IME they are slightly louder, but not by much. it used 140mm fans so its a dull whoosh rather than a high pitched noise. Probably ~20% more audible, but only 10% more annoying |

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 looking up some basic rates it seems like at 18"x18"x7" and 38lbs each (can someone confirm - sounds correct) its about $600 to ship 5 of them with DHL to Toronto, Canada. If the weight is 20lbs that price is closer to $400. Its possible other couriers can do it for cheaper (USPS can go to around $100/unit) the shipping price is an obvious issue - if you can find a way to ship it cheaper than $100/unit I will bid 0.20BTC each and cover the shipping |

$2 to add another PCIe socket seems worth preventing several hundred in damage
More like .2$ for the socket, and it's probably even close to 0.05$ in the bulk quantities they are using. Standard rating for the crimp pins is 9A, so we should be safe up to 324 watt (3x9x12), and it already include some safety margin from the manufacturer. If you read the datasheet, it gives a numer of mating cycles. After this number, the material of the pins won't give a contact between pins as good as when it was new, and even in this case, you will be able to draw 9amps per pins with some safety margin left. But as you said, any imperfect connection will ruin the connector, so using the cables around 250/270 watt is a better idea than to max them out at 300-350 watt. all it takes is an imperfect mate on a pin, and that 9A of current is suddenly traveling over 1/2 or 1/3 the surface area that contacts the pin to the cable. bam, fire. and yeah, PCIe sockets are cheap in bulk. my $2 figure was an upper bound for the cost of the part and the slightly increased complexity of the PCB and assembly. There's no reason to require all that power through a limited number of connectors. |
