Looks like I will just buy the psu from them or get something local with the same outputs for it if I decided to go down the road of buying some s7s but am 50/50 again after seeing prices all over the place diff all over too and with the ever growing halving am like hmm
I think the PSU's will remain to be valuable on thiers. I think they get a LOT of extra sells off PSU's by using the 10 PCIe connectors. So as a company I think Bitmain is going to stick with it. And I could be wrong on that. As a company it was a smart move. Kinda stinks as customer that there just are not a ton of 10 PCIe psu's in ATX without going very expensive. But server PSU's have kinda taken over anymore. I don't think you will regreat the psu as long as you have the 205+ volts to start it. The miner.... we will know more after a few weeks of seeing what difficulty does and BTC value. Actually Bitmain says "you can use two X watts atx psu to power this no problems" so why would it void warranty? And i don't really get why you repeat all the time most ATX psu's dont come with 10 connectors. Server psu's outside packages actually don't come with cables at all either and its not a problem. You can just get the cables or connectors you need elsewhere. Then if you buy two ATX PSU for 70$, you will have plenty of connectors. If you go for something like an EVGA g2 1300w, well it comes with 8 PCI-e, so you will need two splitter, which you can get on this forum for 3.5$ each. http://www.evga.com/products/Product.aspx?pn=120-G2-1300-XRIt doesn't get 93% efficiency like the Bitmain PSU at 99-100% load, but it works. (1460w~1480w~ depending your fan speed for a B8) Did you read the post dealing with warranty? You might read it again as I think your talking about different PSU's then the ones mentioned in that post and what OP mentioned in original post. That is the problem is it is going to void warranty which is a shame in a lot of cases. Two 750's are mentioned so 1 is not going to be able to power 2 hashing boards. So it would be mixed and voiding warranty.
I thinks it kinda get's into a mess connecting multiple. If it's in your budget I would get a decent server PSU, and use it. Chances are I don't see bitmain moving away from 10 PCIe, as it has made them money selling PSU's.
So you likely will be able to use these server PSU's more then 1 generation still. And if not can always sell after.
He mentions using 2 - 750 PSU's. If you did that you would be mixing PSU on one blade. Which is very accurate. I don't get why your looking for a issue it seems like from post not sure why. I'm not debating that you can get cables or a EVGA 1300 is a good psu I have multiple of it and yes it is nice PSU but it's also 180 dollars on amazon. So instead of that I normally recommend server PSU's which normally are cheaper. And the bitmain PSU is a good psu I have had no issues with it either so I don't have a problem recommending it with a S7. |

As the title states, I'm hoping we have a few masons and construction folks on the forum that can give me some guidance.
My home was built in the mid-70s and it appears what are cinder blocks were used to form the exterior walls on the sides and rear of the house. The back side of my home is 3/4 of the way underground, but the front is completely above ground and acts as our main entrance. The ground slopes downward on the sides of the house toward the front of the home. I'm not sure what the name for these types of builds are called, but will take some pictures if needed to help visualize my setup.
The room that I will be dedicating to my mining farm, until it's large enough to be re-located to it's own facility, is in the location of these blocks. I was thinking about having a professional knock a hole large enough in the wall to to accommodate a 10" exhaust fan. My fear is if it isn't done correctly, that this could cause foundation issues. So I'm trying to figure out if this is a good idea and who the proper professional is to call to have the work done.
Another option would be to run hard ducting from the room to my laundry room (biggest is diameter would be 4") and either feed the hot air into my dryer vent, or have the small 10"x20" window in the laundry room removed and have an enclosure built that will be used as my exhaust exit.
So pro's...what do you think?
removed pic to save space
I think you picked a hard place for exhaust. Going through bricks like seems like a lot of work if only a few miners. How many miners are you planning on? Do you have the electricity there? It would have to have pretty much everything there for me to consider hiring someone to put a fan there for mining. Do you have any other possible locations in house one that has a window or gable something already to exhaust out? |

Hello. I have two U3 with raspberry powered via PSU standard. I had got a lot of problem (zombie, low hash,... ) until I compiled de bitmain cgminer version: https://github.com/bitmaintech/cgminerAfter compiling and executing that version the U3 works flawlessly, no zombies and stable hashing... When you say no zombies how long has it been up? Long term was hat I always had issues with when I had 3, although I don't think I tried that version. Thanks for sharing though. I had the antminer u3 from about 2015 august with no zombies at all and very stable hashing. Well you are very lucky and one of very few with out automation. To be honest it's kinda hard to believe months of it hashing without zombies. Just most of these did not fair that well with zombies. |

Are you running 70TH in your own mining area or is it being hosted? And I would agree it's a slow ride anymore. I remember when it was a quick 3 month ROI. But no longer is quick and ROI mentioned together.
Patience and being able to hold long term I think are two important things. I like to pay off electricity out of it and hold the rest. Will see long term how I end up on my investments.
50TH of that is at work where I have 20kw of free electricity  the rest is at home where the bill is $0.15/kwhr  That is awesome on the 50th part if you managed to get that for free. What type of work do you do if you don't mind me asking? That is a lot of free power. Sounds like a great setup though. I'm co-founder of and Sr. Engineer at http://www.synchronlaser.com/ so in a way the free electric is part of my comps  14kw of that is concentrated in one area that can tolerate the noise and heat of what is now mostly s7's, the rest is mostly nice quiet s3's in various offices for supplemental heating aka space-heaters along with my 1.2THs (re-branded Dragon) rig I eventually got from AMT. Yes, it is still running perfect 24x7x365 since Aug 28, 2014. Yea A1 really were good miners those dragons were good miners. Some companies shipped with cheap PSU's was only issue I ever had, but solid miners. Now I'm not only jealous of your free electricity, but of your lasers. That is some very cool gear you have there. |

Even though my last U3 died I still left the R1 up and solo mining as part of the compac stick solo pool. As a piece of hardware it's a fun little unit, very useful if you have a U3, but even if you just like tinkering with bitcoin gadgets then it's worth picking one up.
It is a neat piece of hardware. The R1 does have the nice thing of you really could leave it plugged in a wall for years and not notice electricity price for it. I ended up getting rid of mine after I sold my U3's. If anyone has a U3 they honestly should invest in one of these and use Crazy Guy's firmware. It made my life so much easier. Currently I'm using a RPI with some compacs as my "lotto" miners. It is fun even though it chances are never happens. |

Today finished at +24%. Nice!  I had a few words for it none of them were nice. But wow if we can raise it 25 percent during this difficulty does anyone else find that scary? That just scares me thinking about it even being possible. This one is going to hurt. |

I just need to be able move bitcoin from site A to say site B or C and after 24 hours,send back to site A.
Roughly...
Its just a matter of getting around leaving my funds at this site and spreading it around more on other sites.
If I send to my wallet every time it would add up in fees and was thinking out loud in a sense,wondering if there was a loophole.
Maybe I am being to Scottish in my thinking lol!
No loophole really that will help. If wanting to reduce the amount I would suggest 3 main wallets. One that is a paper wallet 100 percent cold, you send long term holdings there. I recently have been using and loving hardware wallets, so a second that you will use more often on a hardware wallet. And last a hot wallet for daily spending. If you have those 3 and use them right it will work out pretty well in my mind. Only thing is if your talking about dust or faucet type payments then xapo might come into play, but I avoid faucets pennies for hours or work does not excite me. |

Why am I losing it. I have even sold DOGECOIN to Zazarb which is not I only bought it , i did an exchange of DOGE to BTC and I sold him under price because I am mining them so no problem for the price ,everything was a win.
This is last time I will post as it was not meant to be mean, I have nothing in this battle. I was just warning when you do something small like "small deal- 5000 DOGE for 0.0032 BTC done.Smooth." with green members it looks like you are trying to game feedback. When you say you sold him DOGE under price..... a lot would think your doing that to try to get a positive from him it does not really help your case promoting that trade so much. I was thinking you should focus on how you have changed if you have. And I was suggesting getting out of loans to help you lose the possible look as you are lending small amounts trying to green people trying for feedback. It was meant as help. But I feel it's going other way so best of luck. Last post here. |

This concerns me since I have 2 batch 9s. What's the reason for the tiny batch? is something wrong with the s9s that they're just moving to a new batch rather than fixing this most recent one?
Batch 8 and 9 were the same to my knowlege. I think some batch 9 got the 9 port IO board ( I could be wrong on that). But that might be only difference is some getting IO board with 9 vs 3 ports. They both are the same less chip model with a higher freq of 700. Some earlier ones had more chips and ran at less freq. But I think design will be same from here on out unless they do a new model. |

thanks for that but what USB HUB To buy tell me what adpter need to get the usb hub please send to me more proof
U3's have their own power bricks or some use PSU adapters. So the USB hub is not as big of thing with them as it is with say a compac that runs off of usb power. My biggest advice is get a R1 and use Crazy Guy's firmware to control you U3's. It will make your life easy with the zombie detection. I used a cheap usb 2.0 hub with the R1 and U3's and it worked fine. |

Before I knew about Novec as a cooling fluid I though that this was just another reagent used in medical industry. There I overheard people talking about borrowing a 50 gallons drum of some used Novec to keep their medical test processing line up. Novec isn't some neutral or noble fluid. This is some sort of super-solvent that can leach nearly anything out of nearly everything. Keeping it reasonably clean is a tightly controlled information, one that Allied Control/Bitfury folks will not disclose.
(made it smaller on quote)
I'm not sure they want to disclose anything really. I view this as the bitfury lightbulb. They put something out there to make some news, no doubt some sites showed it. The lightbulb they said they would sell.... and just never came. I predict this container will not even make it as far as the lightbulb. I think it will remain a rendering. If they make one even as proof of concept I will be surprised. |

Also sent message to Tomatocage which is :
Hi I know that is not allowed to sell carding guides, hacking guides, and buying/selling with paypal as a newbie, all things I have tried and done but, its a long time I am not doing it anymore and nor I will do in future. I am trying to clear my feedback. I have opened a topic in META, named FEEDBACK with capital letters so please could you remove your negative rating, now I don't even use Paypal anymore.
Beside this I have completed successful trades with high trusted members like
Ghibly79, Mr. Relax, Zazarb, Vilkates and ErikaLui.
I am also trying to enroll in a sig campaign but can't because of this limitation of negative feedback.
Thanks in advance.
I think your fighting a very hard if not losing battle. When you do small deals with green people it could appear your trying to gain trust by buying it. Like your loans with no interest that you pick who you give to... does not look great. I would remove your sig about no interest loans, and avoid doing that as it also looks like a bad mark against you. |

IMHO it's a database memory overload... just happened to me
It seems to be a little better now. It was pretty bad I gave forum a break not much fun surfing with 502 error. So seems to be better now. It was pretty bad for a bit though. |

i just tried to test the PSU
unpluged all PCI's then pluged it to power but the fan didn't run
is iit ok ? or the fan should start ?
I would first try eliminating things. Can you try without adapter? See if it powers up without it go to the IP and access it and see what miner say's. If it works without adapter then look at cable next and see if it get's hot. If so stop using it if truly hot to touch and get a better cable. |

Some nice pictures in that thread, not quite as impressive looking as Bitfury, but at least they are real.... Rich They are not near as impressive and are kinda dated as I think the idea of container just sounds better on paper then it turns out to be. I don't know if either of those companies had sales. The second company had price of like 35k for just it being wired up, and cooling. No miners were in that price which seems insane. I think bitfury will stay in renderings as sales just are not there on these, unless they do it much cheaper then others did. |

If the power cord got very hot, then that means it's either faulty or too small or gauge to handle to power being pulled through it. You need to get a new, bigger gauge cable to start. Then you can determine if there was damage to the miner or psu (probably not). The miner likely shut down due to lack of power due to the crappy cable.
If the power cable got hot where it plugs into your adapter, then it could also be caused by the adapter.
That is the problem it could be either of these. The adapter just does not appear to be something I would send 1300 or more watts through. The cable I think is to small of gauge most likely. Getting hot is a pretty good indicator of this. The best of "local markets" might not be good enough I order a decent PSU cable from amazon when I'm getting one for a server PSU like the bitmain one. I have a feeling most local markets unless you have a good computer store is not good enough. |

I didn't think you could SSH into the newer miners, I will see if I can find something about this Ms Miner Monitor, do you have a link handy?
Here you go: https://bitcointalk.org/index.php?topic=596178.0That is the M's monitor he is talking about. It can do a lot "M's Miner (Ant/SP) Monitor v5.2: alerts,auto/mass/scheduled reboot/mobile miner" |

Where do you get stats for the surge protector/adapter. Just looking at that thing it looks pretty cheap. Is it truly rated for this kinda power?
And I could be off base and it is perfect. Just have not seen anyone post before that I know of using a 8 dollar dollar adapter for so many watts.
it was the only adapter availibale in local markets . the questions is do you think thats the problem ?? The other thing is it sounds like your using your power cable from a PC for the bitmain server PSU? I personally use a nicer heavier gauge cable for my bitmain PSU's that goes into a PDU. If your using a cheap power cable i could see that as a reason for it to heat up possibly. Don't know enough to say since don't know what your using. There are different AWG cables. Some are much nicer then others. |
