I'm sorry for your malfunctioning units. Perhaps BITMAINWARRANTY could give you compensation? Or I guess another innocent miner is going to get screwed over by a big ASIC company?
I'm trying to help him but he's posted it 6x all over the boards and isn't listening to any replies. |

Right, I was referring to that. I also don't want to start a quarrel here for nothing or spoil
your sales, dogie. I just believe that there are seldom good reasons for making a sale thread
self-moderated. And to me it sounds more than fishy how you slap a tax on your private sales.
And as I have the impression you wouldn't be shy in pointing out similar things when other
people sell, I think it's just fair enough if I share my concerns.
The reason its self moderated is because that account (cathoderay) is a self professed smurf account, who's only purpose is to attack me. You can look through his post history, pages and pages of posts dedicated to me. He refuses to reveal what his main account is called or why he chases me around thread to thread. You can read more about the activities of the troll account here. [The megahash account is the same, but there's a lot less effort put into that one.] |

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.
Your S3's shipped with the "faulty" firmware so you will have to flash them to the latest 19th December firmware. To check what firmware you have on your S3's, go to the webUI Status => Overview page. Get the latest firmware from the bitmain support page. This is correct, firmware can be found here. Double checking to make sure that latest December firmware is being loaded as standard (if not already). MD5: 7DF1B12D28B25E10AAC37E2EAFC7397B |

nice try, but no way. Others have had the same issue, how is a cap that is raised off the board my fault? I have purcased over 50 S3 or more and other mining equipment.
From where and when did you purchase the S3. When did you return it and to who. Who have you communicated with at Bitmain? |

@BITMAIN:
Do you have plans to change the fan for batch2?
Cheers
batch 1 = batch 2 = batch 3 there is only 1 batch here formed by 3 artificial ones! maybe ''batch'' 4 is the same Did any1 with 2 s5, try to connect 2 more blades to one s5 for a total of 4 blades per one s5? Even if all batches ship near the same time [speculation], they'll still ship sequentially. So the start of batch 1, then batch 1, then start of batch 2, batch 2 etc. |

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)
These items are being sold personally as I am not buying to resell, and I am personally VAT registered. Neither the DSRs not the 99/44 directive cover personal sales.
Dogie, this doesn't make sense and we both know it. There is no way a private sale within the EU implies any obligation to deduct a tax. No need to argue further.. Good luck with your sales and censorship here, I'm out. I am personally registered for VAT as a sole proprietor, and as such must still collect and pay VAT on any purchase. The amount of people who seem to misunderstand VAT is incredible, it makes no difference to the average consumer if I break down the price with or without VAT - its getting paid either way. What it does allow is those in non-VAT regions or circumstances (EU but not UK VAT registered, or outside EU) to understand that they don't have to pay that tax. Nothing you have posted has been deleted. |

Does anyone know what a reasonable max temperature these guys could be running at ?
Is 70C way too hot ? Trying to keep them under 65C right now, but would be good to officially know the range.
Also, found a bug. Changing the frequency resets "Beeper ringing" to it's default checked state.
[unofficial] If you can get it back under 65 then that should be fine. Its more about balancing your premature death risk (ie 12-60 months) than worrying that its going to melt or anything as the 80C cutoff exists there for a reason. I'm not sure you'll get an official reply on this because we're talking about modifications which officially void the warranty anyway. Bug reported, although I think I've seen this one on S4, C1 etc as well. |

Batch 2 likely won't change because those orders were made for a certain product. Other solutions are being looked at. |

as for noise, try the stock fan at 5V. it pushes a lot of air but becomes reasonable volume (still quite loud though)
How do I adjust the stock fans to operate this way ? A resistor cable is the simplest. I'm not sure what this one is rated at, but they usually step down to 9V, 7V or 5V. Also be careful that they can take the current especially with these big boy fans. Next step up is a fan controller, can get some pretty cheap/small ones but again make sure its rated high enough to take the current. Fan controllers have the benefit that they're variable voltage. Both of these waste some energy. [No affiliate links] |

(pre-review because real and pro review for hardware is "dogie class" one  ) My ego likes that this is a thing. It also appreciates scratches and bacon bits. |

USB 2.0 will deliver 0.5A on 5V = 2.5 W
USB 3.0 will deliver 0.9-1A on 5V = 4.5-5.0 W (especially in PC, not all notebook/laptop USB 3.0 will deliver 1A)
Just be careful about assuming 3.0 can do high numbers. Even if a single port can, it doesn't mean the array of ports / other electronics or even the PSU can take many many maxed out 3.0 ports. If you tell a consumer that it will work fine on USB 3.0, they'll assume that if one works then they can put 6 in. Even the 'big' PSUs like the CX750M only have 25A on the 5V rail, of which a proportion will be taken up with other components. |

would be great if some one did something about this. The holiday period is over so there should be some solution now. CanaryInTheMine has a lot of complaints and I am surprised he is still on the depth 1. He has also shown earlier that in the Mabsark case that he is willing to remove others from his trust list if he feels that is bringing his place in the list in question. Just for the record, I was just cross posting the threads because it seemed relavent to the discussion and hadn't been mentioned. I don't hold a position on that particular case (I haven't read it properly). |

Hi guys - Just put my C1 together. Prior to upgrading to latest firmware, all chains showed X across each row... Now I show this weird thing in chain 1 and a few X's on chain 4... http://postimg.org/image/3yowupfdz/Any thoughts? I am using RM-1000 PSU. What voltage and speed are they on now? Different firmwares have different defaults. 243.75 freq 0730 voltage 959.53GH average. Take the case off and have a check for leaks, when you start dropping chips entirely (-'s or just nothing) then its worth inspecting the boards if you can. |

Interesting. 36.9°F outside. Inside is 63.9°. Maybe it's my connection or maybe it's the pool but my hashrate goes though a long slow rise then fall and so on. The temperature of the water out port of the water block is cool to the touch while the air pushed thru the C1 is quite warm on exit, warmer than the exiting water. I just unplugged the single fan so the two closest radiator fans to the ports run. I wonder if letting the C1 mounted fan run at 12v continually would be a good idea. Since disconnecting the single radiator fan the C1 mounted fan has started changing speed fairly often. The hashrate has come up but that might just be the observed cycle.
Odd. GUI Fan2 speed indication never changes from 1200 although I hear it increasing and decreasing.
If its annoying you can try plugging the fan into the other header that it can reach. You'll have to take the case off unfortunately (and all the PCI-E's) to get to it though. You sure you pump seems to be running okay? I can't think of a reason why the fluid exhaust would be cooler than the air exhaust. |

I ordered 4 S3+ and one of them had a crooked cap that made smoke pour out of the unit, the 2nd DOA unit just made a spark when I plugged it in. That's a 50% defect rate out of the gate! There is nothing wrong with my power supply or electrical as everyone including bitmain is suggesting over and over to me. I used a 20 amp single breaker on each G2 EVGA 1300 with just 3 miners on it with stock PCI-E connectors that worked fine on all my other S3, which should be more than enough. I ran regular S3s on this setup since June. I am sorry, but bitmain has to do something to really restore my confidence here. I can understand the S3+ going bad after a few months, but 2 of right away out of the box? Even though I have the photos as evidence, its still feels like no one believes me, it MUST have been something I have done wrong and not anyone at bitmain. Very frustrating. I am sending them back, even after they see the smoke pouring out and the spark from the other unit, they probably will still want to blame me for it.
PM BitmainWarranty to arrange an RMA. Be sure to link to your post describing the issues, what type and how many miners you wish to have repaired/replaced and your bitmaintech.com order number. |

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). |

Good god! That's a whole lot of reading! I can't believe someone actually TYPED that many words! It's gonna take the weekend for me to read it fully, but I'll certainly try  45,000 characters is a lot of code when its all text. Some of my posts have spilled over that but they've got BBcode in them. |
