gonna have to give that a closer look. Damn good price. Thanks.
The switching outlets per-se is a non-starter of course due to the total load 8-10 miners draws but - I have a lot of contactors around with 110vac coils for brute power switching and simple relays with 110v coil that can switch the PSU control pins.
For the chronically lazy miners I'll just program it to cycle their power every 2-3 days to hopefully nip the problem in the bud. For the s5's I'll set for maybe once a week.
I only have 2 miner's on it now. Don't know what the capacity would be, but it can handle up to 15 amps which is what my electric circuit is in my home. I don't have my miner's all in one place, so I may even try to pick another one up. I just like the fact it has auto-ping and scheduling built right in. It may help users with other devices that need a good solid reboot once in a while too. I schedule my cable modem to reboot once a week, for some reason it peps right up after a reboot. One snafu I have with it is you may need to buy those 6 inch 3 prong power extensions because lots of routers and devices use power blocks that take up 2 spaces. They are very cheap on eBay. Even the 12-14 gauge ones. I'd like to find out more about the built in scripting too. I've never used it with my KNC miner but when I got my Ants, I said I may as well get more use out of it. specs say it has a 15A thermal breaker on it so that is the max total loading. The 1650w available is good for a couple s5's or 1 s4. ergo in my case the need to use it as a pilot signal for the ~14kw of server PSU's I'm feeding |

Yep, Gekkoscience boards are also externally triggerable for poweron/off. Enabling EON (DIP switch 3 on a full-feature board, or on by default on reduced-feature) and then give it an active-high signal (anything from 3 to 12V) on the EON header pin will kick the PSU on and off automatically. I put that feature on so they could be used easily alongside ATX supplies for GPU rails and such, and also to make remote administration easier. A single RPI's GPIO pins could easily manage a stack of PSUs from one network connection. Additionally [link=topic=902305.msg10853244#msg10853244 date=1427056080]
Just as when you change the Vcore with the advanced settings it take a hard boot - full power down - before the regulator circuits on the blades reset. Once they shut down just resetting the OS does not clear it.
Did they redesign the S5 with a software-settable voltage? Or is this a nonfunctional holdover from S4 code, which I believe does have actual chip-level regulation? As far as I know, this does not exist on the S5. Nope. s5 with its series string does not have changeable Vcore. Was refering to the s3+'s & s4, C1's there.Think it has more to do with the regulator chips themselves. Based on forensics I did for AMT with their failed A1 miners I assume the core regulators self start as soon as the rail voltage appears. From there they read their internal registers for what voltage to set. Programmable - yes. Changeable on-the-fly using SPI coms, not necessarily. Warm-restartable, nope. What's that link you gave? doesn't work. |

^^ Looking at some home automation bits to mabey trip small relays on the PSU's to cycle the rails on & off. Maybe RasPi/Beaglebone/Audrino home automation programs as well. Biggest point is low cost hardware and the ability to remote in to cycle the power as needed...
Only bad thing is that that requires poking a pinhole in Firewalls and am not to crazy about doing that. Hmm, now if M's Monitor could trip a script to a same networked power controller...
+1 to Bitmain Warrenty for clearly stating what needed to be said: Miners are exceedingly reliable but - once you start getting a lot of them odds are issues will crop up requiring the Human touch. For me it the same 5 miners that get lazy, all the others run perfectly with zero interventions, still 5 out of 37... Troubling odds.

Along the lines of when the Ants update the GUI and how...
Anyone having 1 blade of their S3+ or s5 periodically shutting down with hashrate dropping to 1/2 and yet the ASIC status show all chips are are fine? Not until a soft reboot will the status show ----- for the entire dead blade.
Do a hard boot and all is well again for several days or weeks before they get lazy again. Out of the 37 Ants in my farm 3 s3+'s and 2 s5's do this. Can't blame the PSU's because all are ran off of server PSU's feeding 2-3 miners and the other miners on the PSU are fine.
I have had it a few times on my S5. I am using a RM1000. I just have to reboot even in gui and it fixes it. If it is really happening a lot you could use M's antminer monitor and have it automated to reboot if drop in hash that far. I use M's Monitor but as I originally posted a software reboot does not restore it. Sw reboot *does* show what the issue is though, namely that one entire blade has shut down with the ----- telling that there is an issue with the Vcore. Just as when you change the Vcore with the advanced settings it take a hard boot - full power down - before the regulator circuits on the blades reset. Once they shut down just resetting the OS does not clear it. What disturbs me more is that the GUI and M's Monitor do not catch that. Both say the chips are there and working fine with the only symptom is reporting 1/2 speed. Since sw boot restarts CGminer and only then does the missing side show up, possibly presence-checking is only done from a cold boot? |

S3++ would make a good case for bitmain to consider shipping just boards .... even upgrade kits for the S1 doorstops still out there!
yes, I would buy the boards to upgrade some of my S1 if they are cheap enough. Only if dirt cheap would I consider going the upgrade kit route again. Did that with 2 of my s1's > s3's and while not exactly hard to do, still a pain in the butt. My time and effort is definitely worth staying with pre-built rigs. |

What a load of nonsense! Absolute rubbish!
A PSU is a mining cost whichever way you look at it, I mean, they are not free. <snip>.
Yes because of long useful life a PSU can be consider as depreciating over a longer period of time but - at $20-40usd for the HP 1200w ones and only ~$35 for the IBM 2kw ones their cost is insignificant compared to miner cost. |

On that snippit Doggie spot on. I'm still using the same HP server psu's that I used to run my now retired S1's on, now they run the s3's and in 2 of them together, 3 s5's. So yes, it *is* a one time cost but they live on and on through the generations of miners.

Jeez people are buying these at close to 2 BTC, i guess people still expect bitcoin to go up in the short term ?
are these really that much better than an s4 when you factor in the fact you have to hunt for a PSU ?
Glad I ordered mine within hours, lot less than 2 BTC. Anywho, 'hunt for a psu? Should also do that to cover the possibility of the one in the s4(s) dying. So far mine are running fine but: The IBM DPS 2kw psu is perfect for an s4. My hungriest one reports in as pulling 1450-1500w from the wall... That same PSU will feed 3 stock s5's cheaply and odds are will last near forever.. Search eBay for them |

Also thanks everyone one for your help just glad its sorted now. (Well until i test tomorrow) I may end up buying the 2000watt ibm psu anyway, thanks for the link for the breakout boards, this was the thing i was struggling with as my soldering isn't the best  Glad that went well  Ja the 2kw PSU's are great, lots of reserve margin with a S4 and enough oomph to push overclocking pretty high if desired. I'd think hitting near 3THs would not be unreasonable. and of course 2kw is perfect for 3 of the S5's @ stock speed, maybe even goosed a bit... Oh, re: soldering. When it comes to server power supplies and their associated wiring the most common problem is using a soldering iron that is too low wattage (most are 25-35w). Due to the heavy wiring and large PSU contacts being very good at sucking the heat away you need at least a 65w iron with large flat tip for fast & decent joints |

Hi Everyone, I think my S4 PSU died this morning, I have only had the machine 3 months or so and i think the psu is dead, could anybody help me figure out if it is and how i go about replacing the PSU I woke up this morning to find one breaker on my board had tripped, I checked the S4 and the PSU doesnt show any signs of life at all, I have checked the fuse and thats ok, but the psu does not boot at all, is there anything i can do to fault find. I know i had one of the newer PSUs that didnt have the issue the first batch did, and the S4 has been running flawlessly since i purchased it, just a bit depressing to see one of my best machines go down  Any help would be really appreciated. cheap psu can cause that, never buy a cheap psu, is the important component, you can try to return it but in the end i would suggest a corsair or seasonic 850w should be enough for the s4 850w for an s4???  Hate to tell ya this but my s4's running stock speed and Vcore draw between 1,250 and 1,375w from the wall as reported by my UPS's. My S2's report 1,039w again @ stock speeds. |

My 2-cents is to get an IBM 2kw PSU (208-240v only) and breakout board to replace it. http://www.gekkoscience.com/products/IBM2K_board.html is a good source for the breakouts and PSU's or check eBay for the PSU's. Together they should run around $75-80 total+ shipping. I got 4 of the beasts for when my S4's croak... That's exactly what I'm doing with my 5 S4s, it's definitely the way to go. Anyone know if this would work for an S2 as well? Certainly though is hefty overkill for the S2 as they 'only' pull a hair over 1kw. If you have >208v for feed then the HP 1200w CS (Common Slot) supplies would be a better match. Just have to do some soldering with those tp attach the PCIe power leads as breakout boards are not easy to find. |

Voltage used? Power consumption? What power supply did you replace the stock one with?
Voltage 0.765. Frequency 275. Additional power supply on one card. The remaining three are powered by the native power supply. Power consumption is not measured. Hmmm... I'd think that clock and Vcore needed will pretty much follow what the S3+ or better yet the C1 takes. In fact - your freq and Vcore are exactly what at least 1 of my C1's is set to. Plug power should follow as well. More to the point is that 2.7THs for 160 chips is exactly the same per-chip as the C1 @ 1.1THs gives with its 64 chips. Since it seems that the system can be happy with multiple supplies and I have a few spare HP 1200w server supplies on hand this bears investigating methinks... 2 strapped together is pretty much the same size as the one the s4 ships with. For now thinking 1 sitting external to run like yours. |

Love the bit about "CUSTOMER IDENTITY PROTECTION IS ONE THING BUT WE ARE NOT WE'RE TO LET PEOPLE GET ROBBED BY OTHER PEOPLE."
Thass right! The only robbers Authorized by AMT is Joshua Zipkin and company!

yep, this saga continues. i wish i could say joshua zipkin came to his senses and ceased defrauding folks of hard earned money but... you know joshua zipkin and you know AMT miners. he's a complete scum bag. he lacks any understanding of how to conduct a legitimate business. this roller coaster ride will continue all through out next year. so long as i make zipkin pay for his legal defense i will continue to smile and fight this asshole until the end. hey josh - merry christmas my jewish friend  i have not forgotten you buddy. Looks like zipkin in addition to not paying rent he owed in the past has decided to continue his winning ways by not paying his Lawyers. Here's some court docs to keep you all busy. https://drive.google.com/file/d/0B_er85osA9tfRnRwZFVyREo0eFk/view?usp=sharinghttps://drive.google.com/file/d/0B_er85osA9tfeEVvdHhqR0RmUm8/view?usp=sharingRemember AMT says you aren't consumers, lets see what the judge thinks. Legally I would think being defined as a 'Consumer' depends on the Plaintiffs: Mainly, are they registered as a corp or other commercial entity? Is the cost of the miner(s) expensable to that entity? If not then they are for personal use and fall under the Consumer Protection laws. Just because miners generate income is irrelevant. If you install solar/wind/hydro/whatever alternative energy to your home and 'sell back' any excess to the power company that gear is also generating income. And, said equipment is considered non-commercial ergo - personal and falling under CPL. |

<snip> I didn't bother taking a pic of the dead fans...nothing to see there although mine didn't fall apart like that  Also to be noted is how the top heatsinks come in contact with board components and I don't only mean the asic chips ...I don't think those blue caps are meant to be pressed against the heatsinks by design, also the clear liquid still has not evaporated a week later...what is that? re: clear liquid. It is most likely the carrier for the thermal compound. Typically it is either a silicon oil or Xylitol (a sugar). Was perhaps not thoroughly mixed? As for 'not much thermal compound' - don't know your particular circumstance but thermal compound is to be used SPARINGLY to only fill in minor surface irregularities. Filling large gaps uses an entirely different composition than typical thermal grease/compound. From what I see in the pics it looks like there are matching areas where the compound peeled off between the boards and sinks and thickness looks right. As for the sinks touching the caps - as long as the caps don't get dented , no problem. |
