Not an issue. Since the transformers are not connected in parallel (secondaries tied together and really bad idea) to make the equivalent of 1 big one they don't care what each one is/who makes it/ whatever. Each does its own thing feeding its loads.

Most data centers are not set up for miners. The typical rack has 10kw of power supplied to it. A high density rack would be 20kw. Something to consider. Most data centers around me were only set up for 120v or 208v.
Ja the hair over 23kw load for the rack might be an issue. Need to ask the colo about that. |

208V puts 4x miners @ 27.2A, pushing margins but still good for in-rack PDU's.

Good job thinking things through. All numbers correct as 4x1.44kw @ 220V = 26.18A leaving good margin for the 30A feeds.
As for the Pi's search Amazon, eBay. etc for RasPi Power. Should find a bunch. Go for at least 2.5A out, 5A best. Most are wall warts with universal 110-240V inputs and at worst need a plug adapter to use 220v.

my AUC3 was broken, do you guys know where to order the new one here in US?
Is there an issue with these? I have set up all my equipment Miner goes all green communication with antpool and interface no problem just auc3 stays green and miner never mines( no communication from controller to miner. Everything else seems good? The AUC3 dongle is rare as hen's teeth on the open market. Seems to be made for Canaan or at least custom-coded for them. Yes as said several pages back there was/is an issue with some of the dongles not being programmed when made. As repeated elsewhere: Open a ticket with Canaan.io If you got it the miner through Minerwarze, reference your order# in the ticket. Overall Canaan has been fairly quick to take care of things like this. thanks NFW. I'm new to the mining community and could be missing something if anyone has a way to verify it is auc3. I already submitted a ticket. I bought on eBay drop shipped brand new. It may be complicated to get assistance from Canaan. I really appreciate any help. Okey dokey, the not bought direct from Canaan or their few Authorized distributors listed on the Canaan site will no doubt be an issue. Not to rub it in but that is hazard#1 when buying miners - only use the makers Authorized sales routes to ensure having a Warranty of any sort. Technically that is between you and the seller. That said, at worst Canaan will say to buy one from Minerwarze if in the US, think they also have a EU distributor now as well. Check the Canaan.io site. From there biggest problem will be availability of the dongles. Canaan's Global Sales Director hangs out here and says Canaan is addressing the spares issue. Anywho... All I can think of is to look at the CGminer Status page and see what devices are listed. Example:  Right underneath the Pool information there is a section labeled as 'Avalon Devices'. Those are the dongle(s). My examples shows 2 Devices and their ID's. Any devices (dongles) seen on your screen? If not safe bet the dongle (AUC3) was not flashed. Under that area is Avalon Device Status. Assuming the dongle is seen, all miners attached to the dongles are listed here. The examples shows a total of 5 miners. edit: Hmm, as a question to Steve @ Canaan: Given the right programming software can the firmware in the AUC3's be refreshed/flashed in the field or is the firmware WORM? |

If they require you to 'invest' or buy tokens so you can 'earn more' it is a Ponzi. Period.

No.
The problem is an AUC3 dongle that was not programmed (flashed) at the factory when made. Open a ticket with Minerwarez/Canaan and they will send new ones to you.
And again - post in the Official Avalon hardware thread. This is last time I am answering here.

Pretty sure GMO is full of Shit. They also said they were working on a 5nm, and 3.5nm asic; which would put them years ahead of intel/IBM/nvidia. Just for perspective, GMO said they were putting up $1 Billion for their new 7nm asic production. While Intel put up $10 Billion for a 7nm r&d facility in Arizona.
While all of this is fine and dandy it has NOTHING to do with Avalons... Please continue these discussions in the existing threads dealing with smaller nodes/GMO! |

Post in the Official Avalon thread fer chrissake.. Canaan monitors it plus that is where most Avalon users hang out. Ya know, rather makes it a very good place to get quick answers? Not to mention ja might not even have to sit around waiting for answers because odds are - already in the existing thread if folks would bother to skim through it... |
|

If that's the case get a hold of Canaan through a support ticket, or try to find someone in your country willing to part with a working one.
Which the OP should have started right after the initial troubleshooting was done... Again, posting their trouble in the Avalon thread would have gotten them to this point much much faster... Had they bothered to read it they would have seen others that had same issue and what the cause is. I believe 1st showed up with some of the ones from huge order f*up in August when Canaan was scrambling to get as many miners made/shipped as possible. |

|

Ya REALLY should be posting this in the Official Avalon thread in Hardware... Canaan monitors it. The green lights on the miners says they are alive but idling. Will be blue when they are mining. Wonder if you got some of the un-flashed AUC3 dongles Canaan had a problem with... |

The boards in the s7 and early s9's are all slightly loose in their slots so some sound when tipping them over is normal. Hold the boards in place when you move it around - sound gone? If so then all is well.
Used s7 from where? eBay, Amazon? One of Sidehack's mod'd ones sold through ASICPUPPY?

I think a lot of people dont quite understand that while these large chip using companies buy lots of processing chips, they are wildly different thant a bitcoin ASIC. Fundamentally, all these companies looking to power portable hardware and are trying to make the least amount of heat and power draw while bitcoin asics are the polar opposite. Asic manufacturers are trying to stuff as much power into a small space as possible. Also, the asic market is tiny, a drop in the bucket compared to what these large chipmakers deal with. There is no real incentive for them to spend all that R&D on a niche market that wont give them much of a return.
Also, imagine if the big companies like samsung, intel, and apple did make a chip and mass produce it. The difficulty would spike like never before and all of you would be complaining that they are flooding the market just like you do with bitmain now.
One of the few times a post is so spot-on I've quoted the entire thing  As you said, these smaller and smaller nodes and the processes of making them are targeting very complex LOW POWER applications. In most cases such as the Arm Cortex, entire Systems On a Chip (SOC's) that even running full-tilt consume less that 0.5 watts. That does not easily translate into a shitload of simple but densely-packed SHA cores on a chip sucking in over 10W... Plus, as ya said: Diff would go through the roof. Be careful of what you wish for without thinking it through - you just might get it... |

Where are you guys getting this bad information?? You tube if I had to guess.
The same places they 'learn' from to think that Bitcoin is a general term for any crypto coin so any altcoin they hear of is 'Bitcoin'. Makes ya wanna smack'em in the back of the head at times... |

Imagine mining with cellphones, even super slow, many many people would surely buy into crypto.
Its all about taking part and excitement
You are a few years behind the times but then again to Newb's, everything old is New to them... Several Major Players already floated that idea / ICO and took in millions from Investards. ref Smartphone Mining Chips. and full article from PC World here. For a myriad of obvious reasons like processing power (minuscule to what is needed) to battery life and more serious gotcha's it failed of course. However the core concept behind the software was reborn as the 'voluntary' Monero mining that several sites such as PirateBay have you run in the background liu of showing ads while you are using their sites. |

Thankfully the lions share of my 250+THs is at work where the power is part of my perks (good being co-owner  ) so here I'll stay. I'm Fuzzy (and warm) here. Come on lets crack this sumbitch of a block! |

The HP PSU's? Like all real server PSU's they are solid as a rock even when pushed over rated max. That is why the HP and IBM server PSU's are preferred by miners (with 220v). Running the HP 1200's at full 110v feed load (900w) yes the fans will go into hairdryer-mode and the supplies will get rather warm but the PSU's are made for it.
The AP3++ supplies are also perfect. Main advantage with them is all the power leads are already there so is plug-n-play. I have a couple dozen of the older APW3's and zero issues with them.
As a side note, you *do* know that these miners are LOUD and hot right? As in a perfect 1,400w space heater. That fact cannot be changed...

Do these websites allow us to hire more GPU Miner?
GPU's CANNOT profitably mine BTC and have been obsolete here for over 4 years. GPU's can ONLY be use to profitably mine altcoins. Yes the alts can be exchanged for BTC but that is NOT the same as mining BTCOP and topic of this thread is BITCOIN pools -- not alts. Learn what the various crypto coins actually are and post in the correct areas. For GPU and other altcoin queries that sure as hell is not here.... |
