I made sure to ditch the shabby wire harness. Who wants to blow up a board?  |

I plugged my 4 pin pump end right into the 3 pin PCB I got from FrozenCPU and it is powering it just fine. |

Does it matter which hoses go into the radiator, just as long as as the output of the hot water goes into the bottom of the pump? Seems the hoses are backwards here, but temps are good and it is hashing well. Take a look.  There is no problem in your connection.But personally I think it's better to let hot water go into the top of the radiator,since the pump would be under less pressure.Parts of cooling kit improved,online video haven't change yet,we will replace with a new one as soon as possible. Syscooling, I set it up just as it is in your video. Now you are saying there is a better way to hook everything up and you are going to create a new one now? Please get with the program and up to speed on your own products. |

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? |

Bitmain are now offering to host the units at UMISOO. Have any of you dealt with them before? Can they be recommended?
So far, no info on how much hosting fees would be. I have contacted them about this and will publish here, if I get the info.
I am just concerned that their miner setup monkeys might be less careful than me when setting these up and watching for leaks.
Not sure if I should not opt for S4 or multiple S3+ to eliminate potential problems with the watercooling.
If I had the available electric I would buy an S4. I have the coupon for it. |

It is very difficult to tell exactly where the pump is leaking, but from the image below it looks like it is between two "plates" that make up the body of the pump.  Before I hooked everything up I made sure all screws were tights and things were in place. Including the 4 silver screws on the bottom of the pump. I believe they were tight, but I may have made them a tiny tighter when going over everything. I can't see why anything would leak, these aren't even pressurized systems. The water just flows through. Did you try contacting Syscooling or Bitmain for a replacement? I emailed FrozenCPU asking them what would be a good backup/alternative to the pump we use here. |

And the above photo, what does that X in the ASIC status mean? I assume it has something to do with with why I can't get 1000GH/s anymore. Does Bitmain have an RMA process or recommendations on a miner that ran for 8 hours at 1005GH/s now only tops off at 986GH/s?
What is that X? The rest are 0's.
A chip misbehaving. You could try upping the voltage by one step to see if it goes away - if it doesn't from a hard reset. What's the max voltage to use without hurting it? My "X" came back, so it is not hashing at 1TH again. I've already sent BITMAIN email and he responded asking for a screen shot which I provided. I've had KNC, Butterfly, and Spondoolie, and never had chip issues with those. Why would I be getting chip issues with a brand new C1? |

Can someone explain what the freq and voltage settings do and if they need or should be changed to anything? Seems my hash rate is capping off at 980GH/s, and I'm looking to get that 1TH/s that is supposedly guaranteed. Right off the Bitmaintech's page:
Hash Rate: 1,008 GH/s guaranteed
Thanks
Also, maybe someone can chime on on why I'm getting so many STALE and DUPLICATE shares? Within the last hour:
Antminer C1: 980GH/s
STALE 5120
DUP 2048
Spondoolie SP10 1.4TH/s
STALE 1536
DUP 0
Duplicates mean nothing. What pool is it on, what difficulty? Picture of status page? Don't hate me for the pool. Difficulty is adjusted automatically there, I believe. And we are talking ghash. Just trying to get to at least 1000GH/s as advertised.  |

This pump you bought on Ebay, did you have to switch to a different size tubing or the 8mm worked ok? And you used the same barbs also? |
|
|
|
Remember, the diameter of the tubing is 8mm on this system, and they make ID8 tubing just for that. I'm not sure those barbs will work since the ID of them are 1/4. They will screw in, but I think it is best to keep the entire diameter of the closed loop the same size, which is 8mm. |

Actually the previous picture is exactly how syscooling has done it in their online video. The piece of paper that comes with the cooling kit shows it differently.

I don't want to nag on Syscooling, but one of my Dads pump is starting to fail and it has only been running 8 hours. Making a real loud screeching sound. Bitmain, please speak with Syscooling who is killing the C1 with the cooling system. I'm actually looking to buy other more reliable pumps from frozencpu.com so my C1 won't blow on me or die prematurely. I'm really disturbed by the situation with the bad harness and low quality pump.

@opentoe are you running the b2 miners with the cooling kits included? @dsheaffer is the pump failing etc the b1 equipment? Thanks.. @chowminer.. I think about 1 I ordered two from a diff place only charged me 14$ a piece shipped from LA I'm sure bitmain will deliver just a question of when (prob quick i.e. china factory) but like dogie say theres prob a short que of like 100-1000 they are probably pushing like 20-50 units a day maybe a little more (who really knows?). REgardless I have been sitting here telling myself I would much rather wait a few days with this thing in china and them testing it then me rec. faulty product with all of the nightmares these other people have been xp with b1  now im praying my fans are not gen1 harnesss. Jesus i wish i just stepped up to the s4.................... why did i skimp over a few btc. The s4 coupon is 400 for gods sake.... and ive heard theyre shipping now no delay.. My moneys on this batch just appearing w/o tracking info. I've only ordered twice from bitmain but bot were 3 days to northern west coast. So it may be there tomorrow or sometime next week :/ I want to mine.... Yes batch 2 C1's. All came with old wiring harness. Have not hooked up yet. |

I received both my miners today with the OLD wiring harness. Can Bitman and Syscooling confirm this wiring harness is NOT going to blow up any boards in the C1? So I still have to open up the whole unit to connect the harness.
Syscooling still recommend opening their own pump up to clean it out from dust?

Here is another question that very remotely might be related to firmware or may be is a non-issue.
I will be very specific. Mining on f2pool, I noticed that my old S2' s GHS is closer to what shows up on workers page of account.
But for C1 (runs on 225MHz), the miner shows 900+ GH/S(5s) and f2pool shows less say 689 (20 min avg). It goes little up and down but stays way less than the one on miner. I watched on miner consistently and that number stays close to 900 on miner. This is a one time test and I didnot repeat and could be just a temp weird situation but did get my curiosity.
Anyone can please explain this or has anyone else noticed this ever.
Am afraid to upgrade S2 firmware to new version with cgminer 4.6 for that reason bcz C1 has 4.6 (latest firmware).
Forget whatever the miner says, whatever the pool says you are getting is what hashing speed you are getting. If you are only receiving 689 that's in all intent and purposes that's like half the mining speed. These are "guaranteed" for 1000GH/s. If the hardware can't make that guarantee, does Bitmain compensate in anyway like the other companies do? |
