You do NOT use a separate version of cgminer to run ants. The s9 is a stand-alone miner...
You need to use either the official firmware downloaded from Bitmain or use one of the more tweakable forked versions of it that has been modified by a couple folks who btw are violating the cgminer license by not publishing their source code.

Hi
The pools in question now are: zergpool.com and bsod.pw. They stole from me 4 blocks each one a.Those are crapcoin aka altcoin pools. This area is for Bitcoin only so expect the posts to be moved to the altcoin areas where they belong. b. Those are crapcoin pools - as such, not surprised they are ran by possible scammers... c. You should open a topic about them in the Scam accusations area... |

Yes, I think the PSU is good...have tried a few. I do think it is a bad unit. Looking back in this thread I saw that a lot of these were RMA'd and repaired. Was curious what the repair was, and whether any of it was doable by a regular person without specialized equipment. I'm going to assume you've got a suitable PSU as you seem familiar with gekko products. Only thing I can say is that its a bad unit. Was it sold as working? Sidehack will have to chime in but I believe the fault is the Vcore regulator feeding the chip. I have a proto of one he sent me that can only run at a low freq. |

Most of today's miners usually buy and sell ASIC miners through Ebay and Amazon. In the e-commerce market, these are the 2 largest e-commerce sites in the world, but the prices are very high.
Alternatively, you can also order an ASIC miner at the Bitmain homepage. The types of coin miners here are sold at a much cheaper price.
Despite being the 2 largest e-commerce sites, I still wouldn't trust the ASICs sold in them, just like those sold in Alibaba/AliExpress. They could be faulty or not what you expect. In most official sites like Bitmain, the miners are already sold out. Not only faulty or at a minimum well used, but it is also much too common to find that they they are infected with malware that will try to spread to all miners connected to your network. If you buy any miner through a seller on Ebay, Amazon et al always: 1. First download the latest firmware directly from Bitmain, Canaan or whoever made the miner onto a laptop or other PC that can later be isolated from your network and the internet. After getting the firmware, disconnect the laptop/PC from your network and using either a hub or crossover cable connect it to the miner. 2. Follow instructions on how to flash the new firmware onto the miner. This should remove any chance of malware. 3. Input your pool and workername settings, save & apply. When the miner reboots, make sure the pool and worker information is the same as you put in. 4. Only after all of that should you put the miner onto your network and have it access the internet to start mining. |

Still NO idea why on Earth you want to compile it yourself when the Canaan software works perfectly. What do you hope to gain? The API supports a plethora of tweaks, the Canaan firmware runs on top of OpenWrT so you have lots of diagnostics built in... Oh btw: You do know that the master cgminer git has changed right? Con abandoned the cgminer project long ago and locked his git. Kano - who was the other major contributor in cgminer and arguably did more of the code than Con did, has moved the master git to https://github.com/kanoi/cgminer and it has been updated with several long-overdue fixes along with adding support for the S17 chip, current is version 4.12.00 A general review and guide done by HagssFIN for the A841 is hereedit: on further thought it occurs to me that you are expecting to end up with a bootable image for your pi. That's not how it works. Compiling cgminer results in you having an executable program that you run on top of your chosen 'ux OS. Full instructions are found here in the Compac-F thread.Thing is, ja the 841 *should* work BUT you still will want to know what defaults Canaan has set for running it... Their full source code containing cgminer and all other other code can be found at the Canaan dl site. |

A good place to start for reviews and settings on the 921 is around here |
|
|
|
|
The 921's are a bit of a clunker: Their best efficiency is very close to the same as an 841 and they are not as tweakable as previous Avalon's (like the A821/841) are. The other gotcha is that they use a bigger fan than any other miner uses - it is 140mm - and those are not always easy to find.

The cgminer code is the code used in the avalons.
The Avalons I can get are 2nd hand, I prefer compiling it myself with a safe copy of source code.And maybe I can modify some code for myself. So just dl a new image from Canaan https://download.canaan-creative.com/avalon841/ |

Is it directly powered by the Pi or are you using a decent powered USB hub that can supply up to 2.5A?
All of the USB sticks must be ran off of a powered hub as they exceed the typical 500ma a PC port will supply.

So it still lies:
"World's First Bitcoin Mining Pool"
When you gonna fix that? Ja, ya know - Truth in Advertising and all that? " One of the 1st and Longest running" would be perfectly accurate. Heck considering how long you have been running, even throwing in "Most successful" would arguably be true  |

You apparently do no realize just how much power Bitcoin miners draw (>1kw-3.5kw each) nor the fact that all that power is exhausted as heat -- think giant space heaters -- and the incredible amount of noise the cooling fans make pulling that heat from the miners...
You need to learn a lot more and rethink your idea.

Have you bothered to read *anything* here regarding the S17's?  They have a horrible failure rate and yet you now want to push them even harder? Terrible idea... That said, if you check the Mining Software area - where this question should have been posted to begin with - you will find what you are looking for. |

Ideally I can build it in a way that I run them as miners working for a local full node on an RPI, but for the short term it seems easier to just solo mine to a pool. I've never personally operated a node. It is best to ALWAYS use a known solo pool for mining with any stick miner vs mining to your own node. Reason is simple: Connection times to the worldwide BTC network. Any block you find must be distributed to all other mining nodes as fast as possible to ensure your block is the one that gets confirmed. Considering how very very very very very unlikely it is that you will find a block, it would truly suck to get one and then have an orphan race with you losing because a pool with faster connectivity beat you to it. Any decent pool uses dedicated connections and routing to the BTC network vs your normal home internet connection which will take whatever path is available at the time. At current BTC value of just over $61k USD I for one would never risk losing $381,250 as loser of an orphan race... |

ROFL...
That out of the way, no. They common low cost and very thermally-conductive aluminum. Not much higher cost and less conductive Ti. Some of the heat sinks are anodized and their colors can range from golden, light or dark bronze, or normal silvery aluminum depending on what BM could get a hold of at the time.

With the mention of Coinbase owning Genesis I was just gonna bring that ^^ up. I hope that with Coinbase in the long run calling the shots because of their vested interest, Genesis has learned something about the value of having a suitable DB system monitoring and backing up everything that the mining operation is doing. Ya know -- like Kano's KDB does with his pool where data on every share that has ran through the pool since day-1 is stored and available to him for in-depth analysis when desired... A repeat of that massive screwup would now directly affect their bottom line since given their current hash rate (Google reports over 3.8 exahash per second) I'd think it is a safe bet that they would be 'solo' mining on a massive enough scale for it to be reliable income. Making sure that their proxies and mining software is working as expected *should* be pretty high on their priority list. Like #1... #2 should be ensuring fastest possible propagation of found blocks to the network. Back when that happened they were a much smaller (so to speak) operation and mined through slush so they got paid no matter what garbage their proxies were sending out. *If* they are now a solo operation then there is no pool with a much larger aggregate hash rate to cover problems like that. |

I do have an electrician, but i'm buying all the parts myself. Then have him spec the parts! Are they there just for their good looks? No. If they are a licensed electrician, part of their job description and training is them knowing what the Codes are and how to properly spec all parts needed. He has the eyeballs on the ground so to speak to see and understand what you are doing. Ja it will take a bit of time for them to do it and you will be charged for it either separately with actual work billed later or as part of them doing the whole shebang. If they do this kind of work often, odds are they can get some sort of contractor discount on all the gear needed vs you buying it HomeDepot et al. That said, yes, it is good for you to be able to see the equipment list the electrician comes up with so you *can* check around to see how the costs look before actual gear is bought... Getting tips from random people is not the way to design/build anything. |

The s19 is essentially a 3.2kw space heater with EACH putting out 10,918.85 BTU of heat...
As Hagss said, whatever AC the building supplies will not be able to keep up with that kind of heat output. It's just not designed for it.
