1st thing in my mind.... PSU Please make sure you are using a PSU with 2 +12v rails and each PCI-E cable is coming from it's own rail. (Not 2 PCI-E connectors from 1 cable) If the above is not the case, if you feel confortable unscrewing the hashing PCB on the network port side and other hashing pcb and swap it. Then turn on the antminer with 1 blade only. If it still shows many XXXXX then, it's time for the RMA to get a replacement Hashing PCB Just got an S1 in today and hooked up. I have a section of ASIC status all xxxxxxxx and only running 156 Gh/s(avg). I switched the PCI-e cables around and still the same. Upon further inspection I noted that the RF led is not a steady flashing rate on one of the blades. Only flashes a couple times every other second or so. Definitely not behaving like the RF led on the other blade. Anything I can take a look at?
Hi, the PSU has a single PSU rail with a 552W of DC voltage, which is more than enough. 8 other AntMiners are completely happy with that same PSU. Just for the testing I connected one blade with the PCI-E cable and the other with the CPU cable, where I stripped the cables = same thing. The problem is in the board, so please check my post above and advise if there is anything I can do? I'd rather not RMA, but fix it myself. Of if that is not possible I would much rather get a partial refund as only 28% of the miner is not working. I can let you inside the miner Web GUI to verify. |

easiest way to check is to measure the voltage with a multimeter across the two legs of the inductor (grey cube above the faulting 8 chips). You should pick up a voltage of 1.1V - If this voltage is not present it means those chips have no power. I had a similar issue with my second batch antminer but it was the first 'segment' on the board that had no voltage, thus none of the 32 chips on the side worked. Bitmain was very good at shipping me a replacement PCB Thank you for the tip. I measured voltages at various points and these are my findings: Red: 11.56V so juice is definitely getting into the board. Yellow: 1.1V is present here Green: this capacitor is supposed to be around 12V, right? Yet it measures much lower and the voltage is dropping as I measure it.  Can you recommend if this can be fixed by me: a have a mobile phone repair guy, who is very good at soldering, so if I can replace something then I'd rather fix it myself. Or if it is not easily replaceable then I would rather have a small refund as only 50GH/s are not working, which is 28% of the miner. |

Guys how do you fix the x problem: xoxoxoxo xoxoxoxo xxoooooo oooooooo
Of the 9 Ants I got the last one is hashing at only 127GH/s because only 16 chips are working on the 2nd blade.
I disconnected the cables as told in post 1, but no luck.
Any ideas?
1) whats your power supply. a single 12V rail with >550W is needed for stable operation 2) reboot the miner - usually this clears any chip errors PSU is Corsair CX600M and I use it for the other 8 Ants - it works perfectly. I rebooted many times. I even connected that bad board to one of the other Ants + different PSU and still the same. All tests conclude that it is the board fault. |

Can anyone confirm that a PSU-1000W with 4 seperate 6pin PCI-E connectors suits for 2 Ant-S1 miners?
Do they need the 4pin Molex for each miner?
Thanks!
Check what DC power there is on the 12V line and if it is only one or more. Better post the exact PSU make and model. But most probably it will be more than enough. Without overclock the Ants use around 320W of power from the PSU. I got 2 of them connected to Corsair AX860i and both use 695-700W from the wall. With less efficient PSU (CX600M) = 370W from the wall. No molex required. Just 2x PCI-E per miner and Ethernet. |

cyper, he already won the auction, UNLESS of course you don't believe him.
I have thought about the same, but looks like last merc. sold for too much, so still looking.
sbfree: Cyper doesn't care about trying to win the auction. He's trying to complete a price discovery on a controller board. Correct. |

traceroute: bad address 'openwrt.org'
ping: bad address 'openwrt.org'

nslookup: can't resolve 'openwrt.org': Name or service not known
Taking a guess I would say that you need to put 8.8.8.8 into 'WAN/Custom DNS Servers' in the web interface. +1 Victory!! On top of that the pool was down. She is mining now though,, Got a BTC addy I can send a tip to dropt? I am stuck at Applying changes Loading /etc/config/cgminer I put 8.8.8.8 in Use custom DNS servers but still nothing  |

No, that doesn't sound like a converter cable. I want to convert my 8 pin CPU cable to 6 pin PCI-E, so I can plug it directly into the PCI-E connector on the board.
The extension cables are for CPU, where the 12V lines are on the same side as the clip and are yellow too, so the polarity was not wrong.
But when I stripped the cable at the end to go into the connector the wires inside looked really thin and flimsy. The markings on the cable says 18AWG and 80 degrees, but I have a 18AWG cable and the wire inside is really think compared to these.
Yeah, Do not use those. You got ripped off by One Hung Lo mfg co. I had bought some PCI extender cables, when I stripped it there were ONLY 5 TINY STRANDS of copper inside the wired labeled 18AWG! They were more like 26AWG. I took them back to microcenter and finally got my money back after making a stink of the safety hazard these posed. Dont go cheap on extender cables, sadly, you cannot trust those off brands, they can burn your house down. Maybe Cablez can make some for you? I will definitely return them, but I need to act quick as my miners are idle. I can make them myself, but I am looking for a ready made solution, that I can just buy quick. Any ideas? |

Guys, what do you think is a realistic price on the master controller board with the beaglebone?
A friend of mine bought a miner from phoenix some time ago and Phoenix gave a 2nd controller board for free, which my friend lend out to me to use with my 4 upgrade modules I bought from KNC.
Now he wants to sell it and is offering me to buy it, but because I plan on selling the miner soon I wonder:
should I buy the board from him to keep the miner complete and sell it as it is?
or give it back to him and sell it as Upgrade modules only?
I wonder what a fair price is? It's a very hard to find component, yet is it unknown if anyone actually needs it at the moment.
Is $1000 a realistic price?
I bought a Saturn with no ASICs for $600 on eBay. He had 2 Saturns, and combined them to a Jupiter, so I got the case, controller board and BBB. Can you link me the auction please. Thank you. |

You could just use the connectors and DIY with thicker cables. I know, but it is too much work as I have 9 Ants. I am just looking for a CPU to PCI-E cable converter, basically the opposite of this: http://www.overclockers.co.uk/showproduct.php?prodid=CB-033-AK&adword=google/pla/unoptimized&gclid=CN25_8e_n7wCFfPItAodCnwAOw |

It has only 1 cable with 2 branches. My initial idea was to use the 8 pin CPU connector with an extension, where I cut the cables at one end and just plug them in the board connector, but something went really bad there. Now I have connected both branches of the same PCI-Е cable and all seems to be working just fine - I was measuring temps with an IR thermometer for like 20 minutes. Obviously I would prefer to use the CPU cable, but I would not risk it with these cheap quality extension cables. Now I have to find a way to use it. Could be that you had the polarity wrong. 8pin EPS have the 12v cables on the other side and those extension cables is for PCIE. Because all the cables is all black on CX600m, its very confusing.

as i wrote prior, i use 2 x corsair vs650 for 1 miner , 1 is not enough , crappy psu's i guess Sorry, but you are wrong. The PSU has 552W of DC power and the miner uses 300-320W at stock settings. I think the problem was with the extension cable - the copper lines inside are just too thin. I have now connected both blades of the miner to the same PCI-E cable coming from the PSU and it's running fine. I insulated the charred data cable with some electrical tape and it actually works. I was standing next to it for 20 minutes measuring the cable temperature at different points and while it is a little hot, it is OK. Obviously I would prefer to use separate cables, but CX600M has only one PCI-E with 2 branches. My idea was to use the 8 pin CPU cable, but these extensions seems to be of very cheap quality or maybe I connected them wrong. Am I supposed to connect 2 yellow cables (12V) at the same hole on the yellow connector on the blade? |

Because I was using CX600M, which has only one PCI-E connector I had to use the old style connector on the other board with one of these: http://www.ebay.co.uk/itm/10X-8-Pin-Male-to-8-Pin-Female-Power-Supply-Adapter-Extension-Cable-For-Computer-/360808438711?ssPageName=ADME:L:OC:GB:3160I cut one end of the extension cable and plugged all 8 cables in with 1 hole having double cables as per this image. I was inside the web interface trying to make the miner work for like 10 minutes and then when I managed and it sttarted mining I got the smell coming from the other room: it happened very quickly. So now I don't know if the problem is in the extension cable or the miner. The bad thing is the extension cable burned the data cable of the miner, so it might not work even though I was working with the web interface seconds before I switched it off:    Any ideas what kind is that white flat cable? is it easily replaceable? Also does the 8 pin extension cable look good enough? |

Guys, that empty fan header on the other board - is it a standard one? Can I plug a 3 pin fan into it?
It's a 4-pin, I put arctic f12 pwm fans on all of mine. The connector is slightly different but just push it on and the white bit bends out of the way.  Can you please make a picture of the connector. Thank you. You can see it on the top left of this pic:  Thanks. I know where it is. I measured the voltages on each pin as I wrote previously. I wanted to see a picture of how a normal 3 pin fan like Arctic F12 is plugged in there. I assume the white bit behind the pins will have to be cut off for the fan connector to fit. |

Guys, that empty fan header on the other board - is it a standard one? Can I plug a 3 pin fan into it? Yes, but use the 3 pins from the top, as the 4th (buttom) is PWM and will make both fans go to max RPM if connected by the 3 pin plug (; [/quote] I measured the voltage on all 4 pins: 1st (top): seems to be ground 2nd: 12V 3rd: 9V 4th: 0.7V All seems good apart from the 3rd pin, which is sense, so is 9V an expected value? |
