Why the topic title still show that the price of S5 is 0.25/GH while it is not.
It is 0.32/GH.
Its an old title from a different BTC price. |

1) The first PSU is not suitable as it has 2 rails, which typically means you're relying on the PSU to properly load balance. In this case, its claimed each rail can take 30A on its own = 360W. That's really pushing it and likely explains your problems.
The second PSU is also not appropriate as its dual rail, again you're going to be relying on the PSU to load balance well to not exceed its ~200W on each rail.
Ok, thanks. So ideally I need a 750W or greater PSU with a single 12v rail to power an S5 reliably. Or possibly use 2 molex/PCIe adaptors on one blade. The Seventeam PSU has 3 PCIe leads so I just used them and an adapter for the 4th PCIe. If I had used 2 molex leads with adaptors and 2 PCIe leads I guess it may have worked out better. I'll give the S5 a week or so on the AX1200 to rule out any local issues and then try out the Seventeam again with correct wiring. Thanks for your help :-) The problem is people can say its a 750W PSU but internally its really not geared up to be run at that 24/7. Stick to Corsair and you'll be fine. |

That was fixed in the first firmware revision and was a known bug. You can download the latest S5 firmware here. Thanks, but actually, the Wednesday Jan 7 file system is what's already installed. It came pre-installed in my two miners. But thanks anyway  ! PS. I appreciate you trying to help people out on this thread and I'm sorry you are sometimes received poorly. Your responses are necessarily conservative and it's a shame some individuals find that objectionable. Best wishes! Thanks for your kind words. I guess only some of the causes were fixed in this version, probably the most frequent. On original stock I frozen within 2 days, on this one I haven't frozen since it was released. |

Have had two S5 running flawlessly for three weeks and today experienced an issue (batch four, OE file system, CGminer 4.9.0). One of the two appeared to have frozen. Perhaps half a day elapsed while both controller and Hash appeared stuck. Discovered the problem by observing lower than expected Hash on Eligius and traced it back to the specific S5 by addressing it, whereupon it displayed the miner status page (without my logging in or requesting it), but was unresponsive to GUI selections. Shut down the PSU for sixty seconds, fired it up again, and back to normal. It now once again appears fine.

Ican't remember the last time I saw a domain being sold on here.
Posted From bitcointalk.org Android App
If you go to auctions you will see lots of them. Some people even asked for a subforum only for domain auctions This is probably the 4th thread about it, not seen any action taken yet. |

I know it seems that you and Bitmain have had some sort of falling out....but your guide was so much help when I got my first C1...new from BM.
No falling out, just some of the older products were contracted for a shorter time. I'm still in antminer threads for the S4 and U3 as required. Bought another recently from an eBay seller. Well packed and setup, once I got through moving the red wire in pump/fans harness so it got 12 volts instead of 3 volts, I found I couldn't reset it. Lucky I found the router had assigned it 192.168.1.59.....that got me to log in, but root/root doesn't work.
not where the miner is right now but I will try it when I'm able.....is that the default on some?
Should be root/root as default, you'll have to wait for him for a reply if you want to login. First, why am I not getting a reset? Next do you think the 192.168.1.59 is really its ip and not just what my router assigning it? I set my first one to 192.168.1.200 as a "fixed ip", no telling what it would show if it was just plugged into another router. There again, I got to the login screen with the 192.168.1.59.
I've emailed the seller for login but I'd really rather reset. Conflicting info between Bitmain manual and your guide about resets and can't find much more on it.
Thank you in advance.
This is the first I've heard about reset problems in C1 firmware. You should just need to hold down the reset button on the controller for ~10 seconds until you see the lights flashing. I don't remember the specific pattern but you'll know when its done. |

1) Can you try and find the exact model of the original PSU please?
2) I wouldn't be surprised if it was power issues with a 'cheaper' PSU, especially now its working fine.
3) 2x S5s on an AX1200 should be fine, AXs are immense. There is always a risk that it may trigger its overload protection as found on some larger PSUs, which will prevent it from turning on at all though, its a bit hit and miss. Potentially another CX750M would be safer and more cost efficient for a second S5.
1)Seventeam ST-750PWL running both blades, then tried a Corsair PSU (CX500M) on one blade and either an Antec 500W or this one pictured below on the other blade. I'll have to look for the Antec box for the model number, it's quite old but brand new in a box. I got it as a replacement from Antec maybe 10 years ago, never used it. The S5 is running fine now but it's only been about 5 or 6 hours on the new PSU, so if it lasts a week it will have broken its own record so far ;-) Thanks for your help :-) 1) The first PSU is not suitable as it has 2 rails, which typically means you're relying on the PSU to properly load balance.

I don't know why you guys bother filling this thread with "I thought it was a scam yesterday, I think its still a scam today".... Just let it die already.

Dogie, I am a noob that has been on here for a month or so. I have read through many of your reviews/guides. They have been very informative
and have helped me learn a lot about mining hardware. Thanx for all the info you have posted!!! Keep up the great work!!!
I too appreciate your efforts although I don't say so much (going off to add to his trust rating now..may have done so before can't remember) anyway keep up the good work edit: guess I did do so already heh (as I look at trust rating option)....but anyway thanks again.... Thanks |

Hi, thanks for your guides ? Excellent information.
I have an S5 that has been misbehaving, with hashrate dropping off and temps going down just on blade 1. Eventually I swapped the fan power to the other connector on the top board and it seemed to help. I have had it running using 1 x 750W Seventeam (supposedly coolermasters OEM) 80 plus bronze. I then switched to using two different makes of 500W 80 plus PSU, one on each side, blade one using a corsair. It ran fine for 4 days then dropped hashrate even though all chips show up as fine on the web interface. The temps on blade 1 dropped to 30 though. I have just splashed out on a Corsair AX1200i and plugged into that. My meter shows a max draw of 580.2W on the wall side of the PSU. So far so good, but do you think power could have been the issue ?
Also, I'm hoping I can run two S5s on the AX1200, what do you think ?
thanks again.

They are very annoying. But no-one buys them and the people end up going away eventually. It isn't a gigantic issue.
They don't because its free to 'list' here and the time costs are almost 0. Press "new topic", copy paste, press "submit". Wait for an email, profit if one of your 500000000000 domain threads sells. |

Thanks dogie and biodom!
I think I'm gonna get one of those nf-12. I need the miner a bit more quiet at a longer distance. I can hear it from in my kitchen which is down stairs and around the corner from my stairs and the miner is literally at the top of the stairs. I don't mind hearing it if I'm by my desk or walking up the stairs but not throughout the house. Thanks for letting me know that they are not quiet but from a distance they are not noticeable.
Dogie,
Thanks for the hardware error explaination. So a few hardware errors is almost expected when temps climb, but when hardware errors climb exponetionally, it's a problem. I've cranked the miner up to 300Mhz or about 1Th/s. Temps went up to 61 and 57. Within an hour I got 1 hardware error. It's been at this setting now for almost three hours and still at 1 hw. I like your range of 60-65c it's more realistic to real computing.
Another question...
How do you shut these miners down to say replace a fan or move the miner? Mine came with an antminer motherboard switch. Being a computer geek, I hate just cutting the power. Somehow it feels wrong, but is that what your supposed to do? Just kill the power either with the red antminer switch or the psu switch? Doing this a couple of time switching out fans to try them with temp control lead one board to not respond during initial boot. It was only after full boot and a restart that the board came back online. I can't find a shutdown or turn off setting anywhere, so how dose the rest of you power down your miner for either maintenence or changing a fan?
There is no other way to turn them off but its not a problem and you're essentially doing the same process as on a computer. Software gets itself in order, hard drive does some final shutdown operations, then motherboard flicks the control pin on the 24 pin ATX to the PSU. That triggers the PSU to turn off. You'd be doing exactly the same with your antminer switch. |

Dogie tell me what proof are you or are they expect and how to do this please, to satisfy all. I do this next week
I don't know, ask those that are flaming you. |

I would love to have access too. Some interesting stuff vanishing there.
Same. I would guess its hidden function is so that things which should be deleted / hidden can be as such, or admins would have to double delete to remove infringing content. The side effect of that is the more mundane postedinthewrongplace stuff also gets hidden. |

Back to fans. Noctura not-f12 is supposed to be a quiet 120mm with speeds up to 3000rpm. From reading all this, noise is the issue but you have to decide if you want speed or noise. The faster the s5 hashes the louder the fan because in order to keep the s5 in working temps (below 60) you have to push a lot of air and have the s5 is an ideal location. If you want a quiet fan then you need to sacrifice hash speed because the air displacement from fan has to exceed the heat generated to keep the s5 cool. This has been my struggle.
But I can't figure out why the s5 needs to be below 60c? Most computers run at or over 60c. The over temp cutoff is software set at 80c. I do get some hw but over a 12 hr period and from what Ive read some hw is ok but when does it become an issue?
Unlike the Spondoolies or Hashfast chips (or your CPU) the S5s don't have a thermal diode right on the chip. The temperature sensor is on the back side of the board, and so is really measuring the temperature of the PCB. It's unknown (at least to me) what a good rule of thumb is for mapping die temperature to the temp sensor reading, but it's pretty much guaranteed to be a decent bit higher than what the unit says. Ok, so like most temp sensors, there is a variance and to error on the side of hot is better. Ok so my s5 running at 55 and 58 are probably running more like 60 and 65. But hardware errors? What causes them to occur and why would they occur at temps in the safe zone with no overclock, underclock say at 275Mhz? The miner still functions with hardware errors and they are less frequent than with my antminer U3. I guess the goal is 0 hardware errors =stability but 0 hardware errors = cooler temps in the below 60c range and that is where fans come in. Probably in the 80s, its hard to tell. I'll see if I can measure the external chip temp at least when I'm next in there. I would think the actual temperatures may be even higher, as the data sheet for the BM1384 states a max. operating temperature of 125° Celsius. That's a crit temperature so there's likely to be a safety margin still within that. Say, 15C. So 80C = 110C and 55C = 85C. It could even be lower as the 80C threshold is arbitrary and more of a 'something is wrong if its got this hot' limit. |

Move it out the room? I don't know about you guys but I don't have doors / windows on my ceiling...
Yes, and ducting doesn't exist in this world. Of which there is not one mention here. |

i just stumbled onto this support thread, perhaps a bit late it seems. i have quite a few S3's nearly all purchased directly from bitmain. they have worked without issues for many months. just yesterday one starting beeping for no reason, so i powered it off and on. now it is stuck with the two lights on (green and amber). no amount of pushing or holding the reset button does anything to get me back into it. i do believe it was running 24 Oct as all the rest (about 20) also have this same firmware. am i dead in the water or is there some other hitherto unknown miracle cure for my predicament? thanks to all for your time and considerate reply. cheers! ;-)
i read on another thread, a user named Pautado claimed that "For MY s3 the best firmware is 10/24 it is the one that gets me higher hashrates and the most stable. And yes, I know about the not working reset button and I really don't care about it... If anything goes wrong I can always flash it by serial/jtag..."
how would one go about doing the above as he suggests? thanks again...
And this case is exactly WHY these people making misinformed decisions and trying to convert others are dangerous. Always listen to the manufacturers / experts, its like antivaxing.... Anyway, the thing is if you're not already comfortable with serial/jtag flashing then its not going to be cost efficient to learn. If you PM BitmainWarranty, they'll sort you out with a return for the controller and reflash it for you. There may be a small (reasonable) fee if the unit is out of warranty, but its worth your time if you are in the US as they can turn you around quick. Remember to include your Bitmain order number and a description of your problem [you can just quote this]. |

Hi all,
So I'm a little new to mining btc with a ASIC miner. I just got my s5 the other day and I have scowered the Internet looking for ways to get the most hashing out of it with a quieter fan. All that aside I think I'm gonna use a noctura nf-f12. Right now I have a sonon 100cfm fan that is not as loud as the stock fan but it is still a bit loud. I also have a second fan pulling at 1350rpm 74cfm.
My temps are 55 and 58 at 275Mhz with 2 hardware errors over a 12 hour period. It hashes at about 900gh/s. I've not been able to get the miner to stock settings with other fans like everyone else on the forum without going into the 60c range which I read is da get zone.
Maybe it's my setup, it's out in the open on its side sitting on my desk. When do hardware errors become a concern? Why is it not recommended that the s5 not be allowed to enter the 60c range when over heating is set at 80?
Hi Eddie, You're questions are valid, no problem answering them. 1) Hardware errors are only a 'concern' when they become a tangible amount of mining. Historically that was 1-2% but on this generation its more like 0.2-0.3%. You're a long long way away from them being a problem. 2) 80C is considered a critical temperature, where as its recommended to remain below 60-65C in order to increase longevity and reduce the chances of premature failure. |
