Do you have another S5 to check if the BB is damaged or not. Also try with different PSU if you have one. How did you connect your S5 to the network? Also did you try to reset to factory default?
He already used another S5 to check if its the BB, and has swapped PSUs. I have an Antminer S5 which is not working. It does not appear on my list of network devices and so it is inaccessible by HTTP or SSH.
When the Beagleboard and controller board are swapped with known good components from another S5, the miner works as expected. I've contacted Bitmain support and they've advised trying to re-image the Beaglebone board. The problem is I don't know how to do that, and I can't get a clear answer from Bitmain support on how to do it either.
How have you been in contact with Bitmain? I would advise asking to RMA the controller board as the solutions (even if they work), are rather painful. In the future you can get S5 support here or here. |

I receive the replacement. Thanks BITMAIN.
Glad to hear it, let me know if you need anything else. |

Spoondoolies has enough margin that they can do decent discounts on volume, for ex. Ditto fo the other manufacturers.
Spondoolies has been valiant enough to support the market with reasonably small margins. Their concentration is on quality above all else, including their own profit margins. If you can hold an S5 board and SP20 board in your hands, you'll work out for yourself which one is most expensive to make. |

I received my S5 today and I'm having trouble getting it to hash.
Sometimes it will hash at around 650 Ghash/s for about 5 minutes and then it will be hashing at under 1 Ghash/s for most of the time.
Am I doing something wrong?
What are you using for a PSU? I received my S5 today and I'm having trouble getting it to hash.

Can you upload a screenshot of the status page please? What is the exact made and model of the PSU you are using? It's an Artic Blue 850W, model no. AD-E850AE-A6 (I think) it actually seems to be working fine at 300M at mostly 900 to 1000 Ghash/s, had it going for a good while. Can't get screenshot right now as it's switched off for the night. Its more than likely your PSU's fault as its quad rail, and I can't find ONE piece of information on the distribution of its power across those rails. |

Some how it's hard to know unless you open the hub & check the chips type.
Or you can mail the manufacturer about the chip.
And do not used the original dc supply. Get the power from your PSU.
I will research, thanks. Yes, I have them running off a 850w psu with an S1, thanks.  I mean get the power for the usb hub from 850w psu too Why would that make a difference? Depends on the exact USB hub, some come with pretty lame power bricks. |

So.. I've tried to search this, but I haven't seen anything on it. I have a new S5. It seems to run fine. Every once in awhile, though, maybe every day or two, I will see that it is running at half efficiency.. in the 500-600 GH/s rate. I go into to miner configuration and hit save and apply without changing the settings.. and it goes back to 1150-1200 GH/s. Sometimes it stays for a day or so.. sometimes it stays for an hour. Is this a faulty power supply or a firmware glitch..? Anyone else seeing this happen?
I'm seeing the same thing on my 1 S5. Frustrating. Sometimes a save and apply click in the configuration page works for a full day or two. Sometimes only a half hour.
Hoping there's a firmware fix coming to fix this. In the mean time is there any provision for a periodic reboot built in?
Yes, its a known issue and will get fixed soon TM. Current solutions are timers on the PSU to hard reboot [harsh], or software monitor's like M's to issue soft reboots on hashrate drop. Soft reboots won't always fix it depending on which exact issue you get though. Has this been fixed? The major causes were fixed in the January firmware update but there may be some rarer ones still about. A lot of them are PSU based as every unit has a different definition as to what it considers 12V, which further varies on PSU load. That's not something that can be fixed with firmware updates. |

@opentoe: I have the Corsair SP120's in push/pull, and I can say these are definitely not ideal, as they can only keep temperatures in the low 60's when the S5 is downclocked to about 325, for an ambient temperature of about 16. Note: The Noctua NF-F12 2000, has higher airflow, higher static pressure, at lower rpm's, and lower noise. It is simply a much better fan than the Corsair, period. They do not come cheap though.  SP120s benefit from taping the top and bottom of the heatsinks shut, it improves their performance markedly. |

Sidehack could, but its unlikely to be economical for such small units.

Dogie do these still have the problem with Nicehash and westhash. Also what is the wattage used at wall. Thanks
I believe there is a modded firmware floating around which fixes some of the issues with nwhash, wattage at the wall is ~1400W. Dogie- Can they be under clocked maybe be taken down to 1.5 TH and Lower the wattage. I don't see any real information on this anywhere debating buying one since Bitmain is holding back on the S5s Also what firmware version is running around for the nwhash issue. Can you at least point me in the right direction. Thanks Yes they can be underclocked. Its not a bitmain firmware so its not officially recommended: https://bitcointalk.org/index.php?topic=850620.0 |

Heya, I have an odd situation, had my C1 for months now, since around December working great. Today all of a sudden I get no "X"s across the board, all "0"s but at default Frequency I am only getting average 500gh/s avg. where as before I was always getting over 900gh/s. Any ideas?
Can you upload a screemshot of the status page please? |

Did someone break Bitmain's site while I was away? Was trying to see what hardware their offering up and Boom nothing. Error 521 Ray ID: 1c297d7b53ec1171 Web server is down https://www.bitmaintech.com/Transitioning to cloudflare, just a configuration error and will get fixed once CN wakes up. Might take a further few hours to propagate the changes. |

So did anyone find good replacement fans to make it quieter if your going to underclock or just run at stock? I am looking to make these as quiet as possible when I get them and any information would be truly appreciated.
2x SP120s on the front is the best you're going to do, there isn't enough headroom with a 30C ambient. Sounds awesome, so they push a good amount of air around? I also need the same sized fans for a Thunder X3 that machine is crazy loud, since its a similar design these should push enough air? It won't make a huge difference in noise as you've still got 2 loud fans in there. The SP120s don't do enough on their won but in conjunction with 2 stock fans they can work. |

bitmaintech website is down ..... could we have some movement finally!?
No. I asked bitmain to move onto cloudflare so everyone can can locally served rather than using CN servers. Because the name servers changed it'll take a few hours to a day for everything to propagate. -Or, a setting is wrong while moving over. Does NO mean there isn't any movement on new sales and/or product? It means its unrelated. What happened with the movement we were supposed to see last Monday?
It came and they hadn't decided what to do yet. |

I actually think its possible. If you fill the block with water and close it again it should be able to remove enough heat with very cold ambient air. You might get issues with leaks due to the pressure and plastic caps though.

Hmm I think the S5 and the S4 use the same fans, I wonder how these would work on the S4.
Yes they do, and possibly in a lower ambient setting. S5s have different cooling changes to S4s which use a brute force approach so its pushing it. |

This would also serve to push down global hashrate in the short term. If MBP picks up 15PH/s for a song from people who are operating at breakeven right now, not only do they get a unit (say an S3) that they can run profitably, but during the move they're keeping difficulty increases in check.
It is interesting that they would bother with this though. I would have thought they would be extremely busy getting ready to integrate new Bitfury product into their mines as it is released.
There's just no decent hardware available in the marketplace. Manufacturers slowed down due to depressed btc price. Bitfury announcement doesn't mean a mining product is about to be ready to ship to an end user next week. In fact I think it will be a while before any products ship with latest BF chip. They will mine the shit out of it with first batches of their own chips... My understanding (quite possibly mistaken) is that MBP is a pretty premier partner of the Bitfury group, and I would have expected them to get pretty early access to new hardware. A lot might have changed since 2013 though, that might not be the case anymore. That's the interesting part. This project won't be without delays too, I would assume. If they are looking at getting offers now I'd expect it could be a month or more before any significant volume is decommissioned, shipped, installed and running. As far as I know that relationship existed when a group helped organize mass production of first BF chip. Since then, the new BF entity is different with none of the past relationships in place. The name BF is same, but it's a different beast today compared to the original group. So MBP does not have any tie ins anymore as far as I know. That matches up with what I've heard. MBP were important in the early days of 'super farms' and make some money investing big in Bitfury hardware, but past that there is nothing special there. |

I had another S5 loose a blade on Sunday (2nd one that has failed in the 30 days I've had them). I tried using a different power supply and also moving the cables to the other port on the controller but it's still going all xxx's. I'm not overclocking, just running stock settings. I emailed Bitmain support but only got one response asking what kind of power supply I was using. I responded back (EVGA 750G & Corsair HX850) but heard nothing further from them. Bitmain, can you send me an RMA number and I'll ship this back to Colorado?
Hi, we are in the same boat. 1 of my s5 blade dead in a month and promised to give shipping label to ship back. But its already 3 weeks since the promised and I never heard back from them again. I send couple email but no reply at all. BITMAIN if you read this please prosess our RMA. I Have been loyal customer since antminer S1. Thank You I had another one fail a few weeks ago and Bitmain Support was much more responsive then. I don't mind paying the shipping to Denver, just don't want to ship it back without an RMA number or confirmation that they will send me a replacement. By which method did you each contact? Email to info@bitmaintech.com and pm to BitmainWarranty on here. Thanks. I'll give the teams responsible a poke. Hi Dogie, can you help me too please. here is the last email, telling me that shipping label will be generated. Bump the zendesk ticket, that date is very old. |
