Hey guys,
I have a problem with one of my Ant S4's. This evening it looks like a board went out and it won't come back. I tried the following troubleshooting steps. The Chains do not show temp which is weird.
1.) Change Pools
2.) Reboot Unit
3.) Power Cycle Unit
4.) Upload the two new firmware in order from bitmain site.
What are the next steps?
Open up and inspect for damage. I'm not sure which board will be your board 3, might have to unplug one and test each time. Once you've found it and if it looks good, try swapping over PCI-E and data cables. You don't need to have all modules plugged in. Its in a datacenter. Any chance of an RMA and just getting it swapped out? You'll have to send a request to info@bitmaintech.com for the RMA, was just wondering if we could get you up and running without downtime. |

Do you acknowledge that it was wrong to write RMA time.
He had a dying board, we asked him to post additional info to see if we could get him up and running without an RMA. It wasn't possible, so I confirmed he needed to RMA. What are you talking about? |

Indeed RMA time? If my S4 can not handle with frequency 218,75M , Can I require RMA ?
Bitmaintech only writes :
Specifications: * Over clocking: About 10%, but not guaranteed
and S4 arrives default with frequency 200M (default) not 218,75M
I need an RMA as well . At frequency 250M S4 had 13 dead chip ( 13 X ) and only works at a speed of 2200Gh/s
Or is the limit of the RMA frequency 218,75M as shown in the picture?
No. No overclocking is guaranteed or even supported. |

I wonder if it's possible to link them, if you look at the bottom of the C1 the fitting look like you can link more than one to each other. Anybody try to remove the 2 caps at the bottom fitting?
Thanks
No, you link them by running two in series. Instead of going from the C1 to radiator, you go C1 to C1 to radiator. |

Where do you get the coolant? I have automotive anti-freeze coolant, is that doable? How much coolant do you need?
Its in the OP |

why cant we buy the units at the co office at a reduced shipping rate?  Because they don't magically transport to CO in the first place. If you send 2 or 20 via air, its still going to cost relatively the same. THEN you have to send within the US by air again, so both trips combined will likely cost more and take several days longer to get to customers. |

for ease of demonstration i gave just one example of a glaring error in your ratings system. There are many. i could go through every line and show that most of the numbers are fabricated to suit your choice of which companies go where.
An 'example' which turned out to be you not reading the criteria and blaming that on me, nice. no, I've proven one example where your exact criteria is very explicit and where you've deliberately chosen the wrong numbers to make one company score higher than it should and another score lower than it should. you've already admitted 'i got you' and that i was right, but will you fix it in your chart? of course not. because you never let the facts get in the way of your scores being absolutely your decision. in that particiular example, bitfury would've scored -4 instead of 8. thats a 12 point difference, taking their score from 92 to 80. that would take them from position number 1 in the chart to position number, er, 8? you see, it makes a huge difference to your chart. its not a minor error of a bad doggie who should wag a finger. its a MAJOR change in position of the top rated company in your list, simply because you've arbitrarily doled out the numbers in the way you see fit rather than relying on the facts. as i said, you can go through every single line in your ratings system and find HUGE errors that amount to deliberate manipulation of the figures. the entire ratings system is YOUR fabrication. Confirmed, you can't read. 1) As I've said twice already now, there is no FF ratings any more. 2) No, you didn't 'get me', I was mocking you. Everything you said was absolutely wrong - as you'd see if you actually bothered to read the rating criteria. 3) Oh dear, how would a company score -4 on a scale of 1 to 10? 4) Not only are you making mistakes, but then you're repeating them again and again and again as if you know what you're talking about. |

I'll pick out the bits which actually have content in to respond. I'd prefer we did this in one of my threads in the future as its OT here, but I have to refute your claims. for instance, you STILL to this day, maintain that bitfury has 'ethics score of F = 8 points' because they have a small mine (really!!!!? ). Had you not been biassed (or is it just blind?) the real score would've been 'FF, because they have the largest private mine in existence, dwarfing everyone else's... and a score of FF would've scored them -4 instead of 8 according to your own ratings FF was removed from everyone, its no longer used. KNCMiner had the original FF because they specifically said they wouldn't mine against customers in a large fashion, then absolutely demolished that promise. manipulated the numbers to have the ratings come out how you want
Manipulated the numbers positively and negatively against two companies I have no relation with - hmmm. And those 2 point 'manipulations' on a 100 point system, damn I'm a bad boy today.  By contrast, KnCMiner, you have scored as ethics F O , which is a huge private mine (-4 points). Does it even matter to you that KnCMiner's mine is significantly smaller than BitFury's yet your scoring system has it the other way around?
No, its not. F = Operates own mining farm = -2 and O = Other generic unethical behaviour = -5. Nothing about size of farms here. This is just pure bias and emotion - ignoring the facts. its a terrible ratings system, Dogie, because its only You and there's no objectivity in it at all.
The evidence you've provided is irrefutable, you got me. But in all seriousness, you've said nothing that suggests I've manipulated the ratings or I have any personal or emotional attachment to the two companies you've stated. On the other foot, your post history suggests you are extremely supportive of Cointerra, and are annoyed that they have a low (rightful) rating. |

looks like i may have to take my chances and hold system cooling and dogie to there word that the harness is totally fixed.. (will do my best to inspect harness too) no reason to doubt either of them. As a matter of fact if i take that risk and it works flawless i will trust them more. We will see in about 12 hrs  There have been 100s of v2 harnesses used, and 100s of v1 harnesses used. |

What the hell. Now I have a complete row of X's. Is my miner slowly dying here?
BITMAIN- help!
I have an S2 that behaves like this. It'll run for a week or so and then an X appears. Sometimes if I power cycle it, it'll go away. Other times, I get more Xs. It's luck of the draw for me. Right now I've got 3 Xs, but it's running at 1 TH/s so I'm ignoring it. It's always been like this. I've replaced two chains, and the power board, and it still does it. It has an oversized PSU in it as well. <shrug> If I were you I'd work with Bitmain and get it replaced. If you're in the US, make sure you work with the Colorado branch, much quicker than the China branch. M S2s are different (in regards to the cause), C1s should fail like S3s. What PSU are you using, and are you sure there is no leaks? I'm using an Corsair RM1000 and there aren't any leaks at all because I haven't needed to top anything off for a while. If I could just get 1000GH/s out of my units which is why I bought them I'd be happy. And now my Dad's C1 one of his entire boards is dead. Reads no temp and has -------------- on ASIC status area. I'm starting to doubt the reliability of this hardware. Will there be any compensation for when shipping hardware all the way back to China if needed? Shipping is to the US. |

Yes, investors are very important, that's why reputation is a main factor for mining business today.. One look at Dogie's rating will enough for investor won't give even a dollar to Cointerra.
What about 21e6? They are in the Unknown group by Organofcorti statistics, aren't they?
i dont think anyone in the real world takes dogie's (biassed and inaccurate) ratings too seriously. there's few ratings there that can be substantiated given the facts and his ratings are very openly based on emotion and anecdote rather than actual data. ive tried to work with him on improving the accuracy but reality doesnt seem too important and he's not able to take input nor criticism from anyone else (certainly not me). im sure its also a coincidence that several of the companies that paid him (in cash or kind) to write a guide for them may have scored better in his ratings than they deserve. as for 21e6, rumours are theyve raised a significant amount of cash from silicon valley investors... and are now working on their third chip... (apparently the other two werent especially competitive). im sure they're mining so they must be in the unknown category, as you say. Actually it was you who wanted me to downvote companies across the board for personal transactions you'd had with them, not me. I set up a numerical criteria system so I don't have control over the ratings. |
