Hi Gents,
What is your average ambient temperatures?
Here in South Africa we have been experiencing temperatures from 27-39 degrees C.
My S1 was running at 51-54 degrees. I read that the units should not reach 60 degrees.
My S5 is running in a 40c room. The chips are right around 60c and working perfectly. 60c seems quite cool, so I don't expect any issues at that temp. I can hold my finger on the heatsinks just fine. The temperature measurements are relative to the type/location of sensor being used, but you're right 60C is pretty cool still. |

... I dont have a bias towards or against Dogie...
With the exception of his un-proportional reaction (IMHO) towards our SP20 Legendaries review party, I have a bias towards Dogie. Bick changed the post thread title to "Dogie spam", but this is still the Spondoolies Spam. It didn't matter who's owned the review party it was a dangerous game to play as we're now seeing. In the same way as publishing an exploit, it doesn't matter if the publisher gets close to breaking the system as a demonstration but doesn't push it further, because someone can then utilise the exploit to entirely break the system. I will need Bitmain's permission first and everyone involved should expect an unbiassed total wipe of all offtopic spam.
The main BITMAIN account can answer that, although get the PM in soon as after tonight its Chinese New Year and everyone will be hard to get hold of. |

Problem with that is single point of failure.
It is. Which is why you'd probably break them into groups of 4-8. Although actually I can't remember if I read somewhere that a failure in the chain doesn't actually break the link. |

So it runs with separate controller (TP-Link or RasPi), right? Can't see this stated in this review. What about overclocking? How to do it and what are the results? Funny to see AntMiner-styled UI.  Avalon was using that interface before Bitmain even sold their first miners (Avalon 1). Looks like a decent miner, but that price is just not competitive...and no built in controller. They do have quite a good system in terms of chaining miners which I like, so you could put you're entire farm on one Pi if you felt so inclined. |

In other places it mentions copper in the radiator. The chambers are definitely coated with something, and the connectors (and inside the threads) with something also. It doesn't cost much more to be safe, rather than slowly ruining a C1 and cooling kit. |

Now, why wouldn't Bitmain want to keep its good name by associating with Swiftec instead of SysCooling?
One pump costs 10x more than the other, at least. The point being you could buy 5 SysCooling pumps (4 as spare) and still save half your money. |

Dogie, it seems your employer uses the exact same method - sending review units (of course in a much less elegant way ...)
Two review threads already popped up.
Don't you think you should open another meta thread to discuss it ?
That's for you to talk to Bitmain with, I'm dogie not Bitmain. Also, I did not open this thread, I didn't even post in here until the second page. |

How am i get a miner in Kuala Lumpur, Malaysia
"Blackarrow X1 - ~100GH
Including internal controller, inc PSU.
Base Price: BTC 0.14"
Hi, I'm not sure what you're asking? Why do you collect taxes? As I understand it, these are used units and you're selling
them as a private person, not as a business, right?
I am a VAT registered entity, and as such I have to charge VAT on products sold to consumers in the EU (as would happen from any other store) |

Correct. Anything cgminer based. |

 Well there goes the hash rate! |

Oh I didn't have any specific cooling liquid so I am using distilled water at the moment?
You will have problems due to the mix of copper and aluminium in the loop. I have no idea over what timescale it will become a problem, but it would be advisable to add an additive or swap out to dedicated coolant which won't have the same problem. So the provided cooling radiator is copper? That's a surprise. Because water carries 50% more heat than ethylene glycol, the basic ingredient in most antifreeze coolant, I want to use distilled water (~.68 cents/gallon in Walmart) and perhaps rig up a PVC water filter with the guts from a quality water filter advertising removal of metal ions. Go with the coolant. What ever you save initially you will pay more in the long run if you don't have coolant or additives if you truly have to go with water. Well, the corrosion shown at a water block port was likely caused by the use of hard tap water. Distilled water alone would have slowed that way down. Distilled water with an ion filter it likely won't happen. We're talking about a 50% increase in heat carrying capability over ethylene glycol. When you use the phrase "in the long run" you must be addressing those getting free electric. e.g. padding their office expenses as for the rest of us profitability might not last long beyond recovering cost. Look at the Jalapeno. The heat capacity of water over EG doesn't impact performance that considerably as the bottleneck for heat removal is the dissipation of heat from the radiator (not to the radiator, or block to water). It is measurable, but its not important to us. |

SP20 and C1 are sold, thanks for the enquiries.

Their site is still up. Scammy though.
I could never make contact with them either |

Thank you! I would have powered it up but UPS knocked on the door just the very second we were leaving, and my wife has spa treatment (she's in there now) I have a massage at 12GMT, but it's not my sort of thing.. i may just get a beer and massage my throat  Glad you received it!! Wish you let it hash before you left to the hotel, so it could made you BTC while you sleep My s5 arrived this morning just as i was going out (wife and i at hotel for a couple of days) so i haven't had chance to unpack the box yet. I'll do as full a review as i can and set up some pictures for all your viewing pleasure when i get home on 31st.
Thanks Bitmain!
Pah.. coulda got home and back in the time it took to get a spa treatment and massage  "damn I think I left the gas on, just going to nip home and check.." Disclaimer: BITMAIN can not be held responsible for being beaten by the wife, due to a preoccupation with miners. |

Just wondering, since these things run on 12v, has anyone tried running an S1 or S3 using a car battery?
Why? At best you'll get a few hours of a decent one and a battery will typically drop voltage as it discharges. Both of those don't really make them appropriate for mining with. Maybe to run it of an old disel engine running on some cheap (disgarded/cooking/frying?) oil...  The idea originated as an off the cuff semi-technical discussion around could you, then very quickly turned to should you. Could, yes. Should, no. For the reasons dogie cited, of course. Where's a functioning water mill with 12v generator attached to provide extremely cheap energy to run miners when you need one? Answer: Not around here.  I would probably say couldn't for quite a period of the battery's discharge cycle. I'm not sure at exactly what voltage the S3 stops being able to hash but at something like 8, 9, 10V its not going to be happy at all. |

Annndddd...bookmarked. I just purchased an Antminer U3 to test the waters, this guide is comprehensive and easy to understand. I wish I could tip you.
You can, but its not required by any means! |

i am glad to say my case is finally closed to my satisfaction.
thank you BITMAIN_janet.
Dont give up, persistence is key.
