If only S5 was in the same case like SP20... Or like S3...
personally, i don't care, but closed case looks more 'retailish', I agree. It saves an alarming amount of weight by opening up the top and bottom, as well as replacing out the metallic sides. The S5 is a total lightweight compared to the S3. And that means less steel being shipped round the world. |

S5 Question - possibly noob question apologies if this has been covered.
"PSU: A power supply unit is not included, and you will need to provide an ATX PSU. There are 4 PCI-e connectors for +12V DC input and all four are required. Do not connect more than one PSU to the same hashing board."
A CX500M has two PCI-E plugs. True or false, a single S5 could be powered by two 500W PSUs as long as you don't cross streams. One PSU per board.
I have a number of Corsair PSU's, several with enough power and enough PCI-E plugs to run an S5. As I have a number of lower power PSUs that only have 2x PCI-E outs, can I utilize two PSUs to run a single S5?
Would you be able to mix and match PSU cables if you have a dimesional door and Marshmallow Man around to absorb the energy? Is that... is that a ghostbusters reference? |

So you are offering a guarantee on these units as well? (As you are obliged to if
you sell these as a part of your business activities in the EU, right?)
Warranty (if any) is provided by the manufacturer. Items advertised are used and sold in as is condition, although it doesn't mean I won't help if I can. This is not true. If you are selling used (but non-defective) items as part of a business activity based in a EU country to a private customer in another EU country, you are legally obliged to offer a 12-month warranty, i. e. replace the unit if defective. This law is in place since 2002. Since June 2014 there is also a law in power by which you are obliged to offer a 14-day right of cancellation. Do you really force me to find a reference or cite the paragraph for this folklore knowledge?  No offense, but I don't buy a word of this tax stuff. Either you include a regular invoice from your company (and I bet you don't because of the implied commitments, e.g. warranty) or you just raise the price by a fantasy tax. These items are being sold personally as I am not buying to resell, and I am personally VAT registered. Neither the DSRs not the 99/44 directive cover personal sales. |

@Bitmain
Are You will be sale bare BM1384 chips?
On what conditions, if Yes?
[Sorry if that question was already answered in topic]
PM Bitmain, then PM me if you don't get a reply after a few days and I'll bump them. Quite a few people heading off on holiday for a few days now. |

It sounds as though Bitmain and the s5 followed AM's one fan option to dump a lot of heat. We know that didn't work out too well long term.
Personally I think the Tube was a great, great layout to remove 900W with 1 fan. And that was coming from the Cube which again, raised the bar of what you can do with a silent 120mm fan (350W). |

Thats not a problem in using smaller PSUs, but isn't the CX500M using both off one cable strand? Although if you're proposing to use 2x for 1x S5 then that's not a problem. Awesome, thanks for the confirm.
Second question, for sure helpful for me, may be helpful for others. I plan on picking up several S5's to run at home. Have seen the Good News about overclocking potential of ~1400GH. All things considered, which power supply would you use to run your S5? 1st 2nd and 3rd choices, please. All Corsair PSUs:
1x HX850W
1x HX750W
3x CX750W
2x CX600
3x CX500M
Bitmain says 590W at the wall. As listed, they are pretty much in 1st 2nd and 3rd choice order now, yes?
Appreciate the feedback.
If you bring down the clock speeds just a teeny bit, you should be able to fit 2x S5s onto a RM1000. Those things are beastly and do go a bit over 1000W. Else you have to drop down to CX750Ms (best for future miners and other wise best choices after RM1000). See the PSUs link in my sig for more info comparing them. |

Does anyone else here have a 50A+ adjustable power supply? I'd be interested to see some efficiency numbers in the range of 9V-14V.
Now that they have a good ASIC, I would hope they have a board in design that can adjust voltages. This would be a perfect setup for the S6. I guess it will depend if they have spontaneous combustion issues with the S5. I don't imagine they'd want to go back to buying VRM components for the S6 unless they need to. What they might do is include a server PSU where you can trim the output voltage through PMBus instead of an ATX supply, but I wouldn't hold my breath on that one.  It will be interesting how the 9V or variable PSU thing works out. At the moment there's no supply, model, infrastructure or experience with them - but now there's a market. |

$60,000 MOQ for the bulk S3+ units is insane.
make a pack of 25 units at $125 each and ill bite.
Will see if it works out in price. I think the main thing is the shipping, even if its pallet sized its going to have to go via air. To return to the correct thread subject title.

[HOW DID THESE GET OUT OF THE FACTORY? ? Cap that started filing the room with smoke: Another one, clearly not inspected by anyone with eyes.... PM BitmainWarranty to arrange a replacement. |

In other places it mentions copper in the radiator.
What other places? Everything I have read says that it is a an Aluminum Radiator. On both the Bitmain website and the Syscooling website. On the original Syscooling listings. You can look inside of the radiators yourself if you want, its coated with *something*. Some of the connections are also coated inside. As I said before though, its not really worth risking it for the small cost involved with preventing problems. |

Hi guys - Just put my C1 together. Prior to upgrading to latest firmware, all chains showed X across each row... Now I show this weird thing in chain 1 and a few X's on chain 4... http://postimg.org/image/3yowupfdz/Any thoughts? I am using RM-1000 PSU. What voltage and speed are they on now? Different firmwares have different defaults. |

Am just about to fire mine up too. Have just done nmap. I've run the pump of course in getting the air out but about to apply power to the miner. I'm trying this with 4 PCIE-8 connectors not 8 only because I don't have the other 4 yet. If the wires show heat, excessive current, I'll shut down an S3 and get the connectors I need. ...
4 should be okay as long as they're on individual wires, and you're checking for heat. |

I am using the upgraded firmware. I am getting near 1000 only if I lower my freq to 243.75 and voltage at 0730. If I use the upgraded firmware settings of 250 freq with 0760 voltage, the first chain shows a few x's after a few minutes...
Thoughts?
What batch is yours from? [Speculation] I believe some of the original C1s are happier on the older settings (including mine). |

I am trying to run this from the command line in the cgminer 4.8 directory
cgminer.exe --bmsc-options 115200:0.54 –o stratum.antpool.com:3333
-u(myuser) -p(mypwd) --bmsc-voltage 0800 --bmsc-freq 0982 --startdiff 6
And I keep getting unrecognized error on all of the options.
Can anyone fill me in what am I doing wrong?
And once it goes ZOMBIE, is there another way to reset it without reseating the usb cable?
As far as i understand it, the guides showing you those settings are quite outdated. After 4.8 you don't really need to give any switches to get u3 to work pretty well i believe. And if you run cgminer.exe --help you'll see the available options. For mye 4.9, its the --au3-freq and --au3-volt thats relevant. And for those, the parameters are straightforward decimal numbers. 785 to specifiy 785 mV and 240 to specify frequency for instance. Just a few posts back i give an example of what i have working with UE3 and cgminer 4.9 That's exactly correct, for modern cgminer versions you shouldn't need any arguments. |

What is the fan noise when compared to a AM Cube. I know Dogie has had both. I have a couple on the way. I was thinking of replacing the stock fans with these. http://www.quietpc.com/cl-swif2-12pThey are rated at 75cpm, but I plan on using two. These fans are very quiet and I have used them to tone down a Norco server. They will be going in a spare bedroom, that is used occasionally . So I want to keed the noise to a minimum. The cube is consistent and is like a quiet desktop pc. You could have 50 in your room and not really care. The Antminers are the same, IF you can keep it on its low rpm setting. As I have a single blade the aerodynamics aren't as good and so I use 2x120mm fans blowing directly on the heatsink to keep it cool and quiet. Neither my antminer or cube is audible over my Avalon running at min rpm though. I bought a couple S1s used and idk if they've replaced the fans but they only run on max RPM. What connectors are they supposed to be plugged into to allow for a variable speed? I have them in a cold room and the reported temp is 25C There is only one connector type on the S1 boards, so it sounds like they replaced the fans. |
