Pool: bitcoincz
Psu: the one from bitmain
What is the status tab do you mean miner status?
Yes. Input to the PSU is 220v-240v range? It probably would not work at all otherwise but best to check. All 4 PCI-e properly connected? And are the one red light on each board on? |

Reduced S5 price to 240$/shipped in Canada. AMTubes to 0.7BTC for all. I'm willing to split up stuff, too.
Just removed the S5's, i received enough 150$ shipped offers to decide not to bother, there is no point for me to sell them if i can simply mine with them for 2 months and earn more than the selling price. I reduced the AMTubes price further, but no longer include shipping. Bump and delete previous Bump. Price reduced a bit. Surprised nobody wants 2.5TH/s for cheap. |

I'm new in bitcoin mining with antminer s5.
It supposed to be 1100 gh/s
But at the pool it's called "scoring hash rate" it goes around 300 gh/s only, while in miner status it's 1th/s.
So what exactly is wrong?
I think may be it's connection issue so I can change the pool's url.
Or it's configuration issue
Or pool issue so I can change the pool
What do you think?
What pool are you using? Try Kano.is. What PSU are you using? And post a screenshot of your full status tab, please. |

Hey everyone,
I recently checked, using an electricity usage calculator, how much it would cost to run Bitmain Antminer S7 in my house, and it outputted around $94.00 per month. Is that very accurate?
Power consumption: 1400W
Power cost: $0.10
Hours of usage: 24 hours
Okay here; On 91.7% Eff my one B8 does 1415W at the wall with 40% fan. On 92.5% Eff my one B9 does 1325W at the wall with 40% fan. If you can get some earlier batches, you might be able to find some nicer units that can do 5Th/s at about what my B9 can give. |

a week ago got a couple of antminer u3's (brand new) running them using cgminer 4.9.2. Hashing went well the first week, now get the line "stratum from pool 0 requested work restart" atleast 5+ times in a row, then maybe a few accepted and then back to "stratum from pool 0 requested work restart" this happens for atleast 10 mins, and then the whole thing just repeats "stratum from pool 0 requested work restart", till I shut it down. Its driving me crazy...the hashrate is pretty decent, getting atleast 50 - 60 ghs average per U3 (which is pretty much what it was rated to run at) check on the net, mostly see comments stating that its a "normal message which appears when the bitcoin chain finds a block as a whole" and "message usually appears on a p2pool" I understand that part, but 5+ times in a row, seems kinda messed and I was mining on Slush's Pool, plus a few other sha256 coins, but same thing keeps happening Right now just boxed them away...want to get right back into hashing  any tips? It doesnt really affect your hashrate, so i'm not sure why you are fixating on this issue. Regardless, what was your pool side hashrate and also what difficulty did you run them at? |

How can I change my Antminer's address if I can't access it in the first place.
Sorry, this issue is bugging the **** out of me and I'm just annoyed.
I appreciate any answer that helps me
Thanks for your cooperation,
Nick
Your computer need either manual routing setup or an 1.# address to access that subnet. If you don't really have a network setup yet, you could look into changing your router's subnet strait to 1.#. So instead your router's ip and your computer's ip would be 192.168.1.1 for the router and 192.168.1.# Otherwise networking is specifically designed so that you cannot access each other's network. Another option would be to get something like Win IP Config and temporarily add yourself a 1.# address but even though its simpler, its easy to get lost if you dont understand what you're doing. |

I received my B9, it was packaged exactly the same as the B8, it appear unused or at least clean, smelling fresh of the factory with no visible use or damage. Performance wise, as expected, but much better efficiency, i don't know what to say about this;  |

Hey everyone I have about $150 TO SPEND to get into mining. I was wondering what to get. BTW my electricity is free.
I second the S3+PSU. However with a bit more money, maybe you could go for a S5 instead, although they are quite more noisy. If that is not a problem for you, i would save up a bit. |

Bump. I'll drop the price to
$2,200
Two S7's are now 1500$, for more hashrate and 3 time more power efficient. They're also 100$ or less each on online websites. |

I have some Avalon 6 pointed at Nicehash, and I cannot get extra nonce subscription to work for the life of me.
First person to give me the right solution to make it happen gets .1 BTC!
You need to download the nicehash stratum proxy and run it on one of your computers, and then you will point your miners to it instead. This will give you the extra nonce sub. https://www.nicehash.com/?p=asicThe guide is here with the download links. Direct link; https://github.com/Stratehm/stratum-proxy/releases |

I checked based on 9lbs and 12x6x7 dimensions and shipping is around $53 US. So I think you are better off shipping to someone in USA.
I can't really Compete with S5 already in the US for Americans, but i think my S5 would be better for Canadians versus buying from the US. Also the duty tax. |

I find him a bit of a bundle of negatives... hope i said it well as english is not my 1st language  Do not mix power supplies on the same blade! I'm talking about 2 blade one one 750w PSU, here. There must of been some confusion, in my intent. I'm not saying to use two 750w on any one blade. I guess what you two read from OP is. "Can i put 1.5 blade per 750W"? Answer is indeed no. You'd need a 850W-1050W PSU and a 650W+ PSU ideally. You'd have to do 2 blades on 1 and 1 blade + controller on the other 1. Would be pretty rough to do this on a B8, you'd likely have to underclock to clear 50-60w on PSU 1. I doubt the Corsairs are as badass for running the PSU overloaded even by a little. And also that the EVGA g2 1300 is also okay for B8. But i acknowledge it would be better for earlier batches since for a B8 you get pretty much 0 headroom. |

Might want to try the Ultra Kaze fans and just spin them down. Also stock fans at minimum RPM, 2400-2600 are not too bad, especially with a cheap acoustic panel absorbing the noise.
I haven't tried the Ultra Kaze fan but apparently they still move lots of air and the noise is much less annoying than the generic fans the S5 come with.

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) |

do you still have any S5's ?
I'm guessing the difficulty raise is scaring everyone away from buying new miners. But if someone has free electricity, feel free to PM me. |

So, the B9 shipped late, but not too late, yesterday, but the shipment is on hold in Hong Kong, with DHL. Whats with "Shipment on Hold"? They needed a coffee break?

So I currently have one S5 and 1Liteon 750W PSU, and am thinking of counting with the S5 for a 2nd miner.
My question is:
Could i share 2 of these PSUs (750W + 750W) across three (3) S5s?
I'm thinking no as although the PSU has 6 outlets, and the S5s have 4 input connectors (i.e. 6*2 =12 output connectors on the PSUs, and 3*4 = 12inputs connectors on the S5s), the S5s apparently need 590 +/- 5 so 620W each, or 1860W total and the 2 PSUs will only provide 1500W, which will not be enough.
Thoughts?
Crash
No, you would need to downclock quite a bit. One 750w per is good for full speed, about 1.3th/s per S5. If you were to run 3 downclocked, i dont see the point, but then you could use only 1 connector per blade. |

just so your following. he just did the math at 12kw --> 12,000 watts. not 1.2kw --> 1,200 watts.
yes i know that.... i have 2x12kw so it's relevant calculation. Now the point is how to remove some heat from the GPUs so i can use AC with 32k BTU i have in mind. Any suggestion for frame, gpu position and etc ? You don't use AC, you slap a high CFM fan in a window, pulling all the air from inside to the outside. Even with free electricity, it would be silly to use AC, since you could instead use the available electricity to run more stuff. |
