Is there a connector on the controller board to connect a WiFi antenna?
No wifi on this controller board. |

not sure i would agree. The temperatures on my unit are just fine, and Im not really concerned at all with the heat of the unit. I run the fan on 5V and aim to have the board temperatures averaging around 60C. With a nearby window cracked slightly an intake of 5C allows me to overclock to 381.25MHz/1255GH without tripping my 612.5W PSU rail (fan is on a 5V rail so that frees up 12W+ for mining). With room-temperature (~20C) intake I have to operate at or slightly under the stock 350MHz.
The plastic sides would likely not deform until a minimum of 100C, and actual melting temp has to be well over 150C, or the temperature that the antminer shuts itself off or would otherwise be failing massively (which nobody has experienced yet).
keep in mind that the SP20 temperature is more air temperature than the board. Asic stats show that the chips are 85C underclocked or up to 125C in normal operation. Antminer chips go into the 75-95C range I believe, and the sensors on it are likely in contact with the hot side of the heatsink. 55-60C is an ideal temperature for the S5, above 65C may spell trouble
that said, 80C is very high, is your garage warm? I found that if you put a cover on the unit air crosses the heatsink instead of blowing out the top around the beaglebone.
Polypropylene is 130C and Polycarbonate is 155C but you're going to need the AIR temperature to get up to that! |

So what could it run if the room is about -30C or lower?
Condensation, so... 0GH 
Am I right in thinking that your top SP31 is sucking in air from the PSU side, but the SP20s and S5 are doing the opposite and throwing air out?
Doesn't that get a little 'circular' ?
no they are all blowing the same direction You can quickly remember which way a fan is blowing as they always blow towards their frame. |

Overnight, one of the blades curiously went xxxxxx xxxxxxxx xxxxxxxx xxxxxxo running at stock 350 with the temps at 63C. Rebooted and it's working OK again.
Hmmm.....I got back from New Years Eve celebrations earlier and noticed the same thing with mine, but all X's. They all came back after a reboot also, but it is a little worrying..... Anyone else had this? EDIT: Also at stock freq with temps @ 65. that's alarming... There is a known firmware bug where one module drops out but both still display as mining and temperatures fixed. This may be the same bug and will be fixed in the next one. And yes, its very much firmware. |

How is the performance in a moderate temperature environment?
eg -6 to +6 deg C
It improves slightly, and it does not like a 35c room it does a little worse. After about 30C you start to lose full hash rate, 35C you're going to have lost full hash rate, 40C then you're down to 1.35TH or so. |

Yup.
+1. We have seen this happen before.
Never admits his role in this whole mess.
If he'd just shut his yap then this would blow over and the SP20s reviews would have come and gone. But no now we have him bumping the crap out of Bitmaintech and his other clients threads and his own guides. I get it he wants to make money but at what point does the forum do something about it?
Blocked dogie from PM's and ignoring him from this point forward.

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. I'm pretty sure they did. there's only 2 (a black and red) wires coming out of the fan which are directly connected to the pos/neg hookups that you had to wire the PSU to origionally. Unless you guys can suggest an inexpensive replacements fan I'll just deal with the noise. Not going to spend $50 replacing 2 fans that aren't broken. I'd leave it unless it really bothers you, the fans will cost as much as the miner. |

I have Corsair AX860's running all of my S3's. They have a "hybrid/normal" switch. When I flipped that switch to "hybrid" on a couple of my PSU's, I had one board on several rigs stop working. My hashing power on each of those rigs cut in half. However, it worked fine when I turned off the power to the PSU and turned it back on. They would work fine for several hours. Then all of a sudden I get an alarm from the pool saying hash is down. I would look at the rig setting off the alarm, only to see the hashing rate was half of what it should be. It ended up being the "hybrid/normal" switch. When I flipped the switch to "normal," I have not had a problem ever since.
With that said, "Hybrid" probably limits the amount of power given to the rig once the PSU reaches a certain temperature. Hybrid makes the fan on the PSU turn at less RPM's. So, if you do not have Corsair's with a "hybrid/normal" switch, it may be your PSU is not sufficient at providing the power needed to the rig(s).
Still pay attention to Dogie. He knows what he's talking about.
Is it an AX or AXi? On the AXis you can toggle between single rail and multirail (which we don't want). |

I'd link to see springs for the outlets that allow the hose to make a curve without collapsing.
You can buy them online pretty cheap, I put them on mine. The colder you get your tubes the less ductile they'll become as well. |

The past week I have been asking for an RMA # to return my U3 from Bitmain and others. I keep getting responses on where to send the U3 but never an RMA #. Do I need an RMA # or not?
Yes and no is the answer. How are you in contact with Bitmain? |

Hi everyone! And a happy new year:)
I bought this device and actually iam not really satisfied with its work.
The problem is that it's hash rate on controller be and pool differs very much.
This way iam loosing up to 30% of hash rate.
For example be speed first week - 3-3,2th, pool speed 2,7-2,9.
And last two days the device productivity dropped to 1,7-1,9 th - pool speed,
Be - Device speed 2,4-2,6.
All boards work and chips have no power downs.
Environment is good temperature (about 15 Celsius degrees) and power is enough.
What can be the solution for my problem?
Thanks for your help
What pool are you on? |

the kill-a-watt I have is showing at 1115 Watts at the wall. Since just moving the box it has been shutting off quickly. The only other thing that I have done is update the firmware a while back and have it set at 196M and 725 Volts. I have a 18 gauge computer cable that showed some wear on one of the terminals. I ordered a 14 gauge cable to replace it. There's some dust inside, but other than that I'm not sure what is going on. Anyone have this problem. I'm close to retiring it anyway, but would still like to know if it works fine (and safe) until I shut it off completely.
What voltage and frequency were you running before? If you're getting 1115W at the wall then you're very close to maxing the PSU. (as are stock S2s though). It's always been stock frequency and voltage. So I'm not really sure why its doing that. In addition, the watts start out at 1090 and then increase after thirty minutes to 1132. After this at some point it shuts off. I'm not an expert on electronics, but could this be something that would be caused by one, the 18 gauge power cable? Or dust in the S2? Or do you think it is the update I made to the firmware? The things you've suggested as causes are all reasonable, although you can probably ignore firmware for hard shutdowns. It will either be PSU load, PSU overheating or your cable overheating in some fashion. |

Dogie's Miner Setup Guides:Nicely formatted version available at dogiecoin.com!  Contents: 0a) What to Expect0b) What You Need1) Powering2) Cooling3) Case4) Configuration5) Troubleshooting6) Where to buy0a) What to Expect (top)Bitmain's AntMiner S5 is their first offering to utilise their new 28nm BM1384 chip, combined with a new string power layout. 60 chips are spread across two hashing boards in an identical layout to the previous Antminer S3. The external case has been removed akin to the original Antminer S1 with the addition of lightweight airflow directors added back to the sides. The S5 is standalone and does not require an external controller. | Chips | 60x Bitmain BM1384 Gen3 | | Hashrate | ~1150GH | | Rated Voltage | 12V | | Rated Current | 50A | | Power.Consumption | 600W |
     0b) What You Need (top)You will need a few accessories and a power supply to get started. Click your flag to find everything you need to get started at Amazon!       1) Powering (top)S5's do not come with a power supply, and you will need a typical computer PSU with 4xPCI-E 6 pin power connectors. All 4 PCI-E connectors are required. We also need to tell the PSU to always be on, as there isn't a motherboard to do this. Cut a paperclip into a U and insert it into the green wire and either black wire to the side of the green wire. Tape it up for safety. The power supply will now be controlled by its switch on the rear socket.   2) Cooling (top)The S5 is self sufficient in cooling terms and utilises a single high pressure 120mm fan which blows through the miner. At ambient temperatures over 30C, the fan spools up to nearly 4000rpm which is very loud and akin to the Antminer S4's noise levels. This is not appropriate for home mining although a number of mods can be done to reduce noise levels sufficiently. The fan's RPM is automatically controlled by the software and reacts to increased temperature. The front of the mining boards are cooled by curved, full cover aluminium heatsinks while the backs are left exposed. These heatsinks are attached using compressive springs to avoid potential chip damage from over-tightening. Its worth noting the careful thermal compound placement on each individual chip which aids cooling without making a mess. Please be careful when handling these heatsinks, they are extremely sharp.     3) Case (top)The S5 returns to an open chassis design, utilising the thick aluminium heatsinks as a sturdy frame. Both the top and bottom are left exposed while the sides are covered with lightweight covers to help direct air over the back of the mining boards. S5's are stackable when placed on their side due to the top access required for the PCI-E cables, however turning an S5 on its side will reduce cooling performance. A shipped S5 weighs 3.4kg and the shipping box measures 230mm x 370mm x 230mm while the unit measures 300mm x 137mm x 155mm. Click here to see a 360 degree view!     4) Configuration (top)The S5 is standalone and does not require an external controller. Wiring: - Prepare the paperclip for the PSU's 24 pin connector.
- Plug in the four PCI-E cables to the miner.
- Plug in an ethernet cable from the AntMiner to your router.
Configuration: - Power on the power supply using its switch at the back.
- Make sure that your router's DHCP table is turned on. You can assume it is already on if you have a typical router.
- Using a browser, navigate to your router and find the IP it has assigned the S5 and navigate to that IP.
- Login using "root" as both the username and password.
- Navigate to the page Status -> Miner Configuration. Enter your pool information in the below format.
- Select "Beeper ringing" to "false" and click "Save & Apply".
- Navigate to the page "Miner Status" to check mining has started.

5) Troubleshooting (top)| Problem | Solution | | "x".in.a.row.on.miner.configuration.page | - There is a faulty chip - nothing we can do. Hash rate will be affected by ~1.5%. | | Almost all "x" on one row of "Chips" | - A hashing board may be mispowered or faulty. Try power cycling the miner and recheck your
cabling and PSU. | | How do I change the login password? | - Navigate to System -> Administration. Enter the current password and the new one twice. | | What is the SSH login? | - Username is "root", password is "admin". | | Can I turn the beeping off when the miner stops mining? | - No, but you can reduce how often it beeps. Navigate to Miner configuration and turn "Beeper
Ringing" to false. | | I can connect to the AntMiner but its not hashing? | - Set the protocol to DHCP via Navigate to Network -> Interfaces -> WAN -> Edit. If you
don't want to use DHCP, navigate to Network -> Settings and make sure "Gateway" is set to the
IP of your router. | | What temperatures should I aim for? | - Try and achieve <50 for best hash rates, and <60 for long lifetimes. Temperatures should not
be let to rise above 80C. | | Where can I get the latest firmware? | - Download from Bitmain's site. | | How can I tell what firmware version I have now? | - Navigate to System -> Overview and look at "File System Version". | | How do I install the latest firmware? | - Download firmware as above. Navigate to System -> Upgrade and click "browse". Select the
downloaded file and click "Flash image". Do NOT interrupt this process or you will brick the unit. | | How do I reset settings to default? | - Use a paperclip to press the reset button - located next to the ethernet connector - down for
5-10 seconds. The miner will then reset with stock settings. | | My.power.supply's.cables.are.braided.or.aren't.color.coded | - See below diagram for pin-outs.

Dogie. Why are the fans on the S3+ so loud when Bitmain markets them as quiet miners? It seems like a little more money could be spent on getting a high efficiency fan that runs quieter so we don't have to go buy aftermarket fans to replace the stock fans on the S3+ units. Bitmain needs to start considering things like this and provide a better quality product for the end users.
The 12025 is pretty much as efficient as it gets in relation to a sensible fan. In terms of cooling, what other people are doing is replacing them with significantly less powerful fans and running them hotter. In order to retain the same efficiency and long life, there is a certain level of cooling (and so inherent noise) that is required. Trust me, I bang on about them all the time about minimising noise, and there are tweaks they can do to improve the S3. But the solutions you're comparing the S3 aren't comparative because they run at different targets |

yes, I shipped them back to the US location.
Can you PM me tracking please, and any references you've been given. |

Yes, one was the bad cap, the 2nd unit when I plugged it in would not power on. So what I did was I unplugged it, opened up the case and plugged it in. The only thing I saw was a spark on the right board, nothing else, the other board would also not power up. I tested these on different power supply, its just like those 2 miners came from a bad pile. I just want them to ship me 2 new units, which from my emails with them is not one of the options they are willing to offer me. I just received these days ago, so there would be no motivation for me to break them on purpose and go through all of this. I want them to send 2 brand new miners, or refund me the full amount. Both of those I was told are not options. It's not like I was mining these for months, they were DOA units! Not something that needs to be repaired! I agree it is odd that I got 2 bad miners, I believe they shipped me miners from a returns pile. I only ask they make this right since it's clearly a mistake. I purchased them from Bitmain directly from the website, I spoke with Yoshi, when I showed him that photo and told him smoke was pouring out he asked me what pool I was using??? He said they are going to fix that fire trap and send it back to me. I just want 2 new units or a refund, I was told neither is an option.
So do you have one or two units which are a problem, what are the problems on both of them? So far I see a photo of one bent cap. Yes, you would not receive a refund or replacement unless you sent the unit back anyway. I'm not sure what the problem is, you're saying the miner(s) are damaged and have been offered to have them fixed? Yoshi has given you address details right? Ship them back and I'll make sure you get new miners. |

Hi there. This is my first post. I purchased four S3’s and have had trouble keeping them mining since I received them about three weeks ago. They will all run for several hours and then GH/s drops down from about 450 Gh/s to about 45 Gh/s.
I had previously been running five S1's that ran great for 6 months. The issue has only begun with the four new S3. They do not drop internet connection they just lower the hash rate to about 45 Gh/s.
This happens randomly with each S3 and at different times. I cannot run longer than 16 hours before 1 to 3 miners will drop out to about 45 Gh/s randomly.
I would much appreciate some suggestions and help.
Wondering if the problems is with your PSU's? Its a known firmware problem, but would be good to know what his PSU setup is as well. |
