Lowered prices on everything left.

Good job, Bitmain! Is it an allusion to your new not yet announced 1U miner?  No, its the same PSU in the S4+, which is 3U. |

I think you'll be better off selling them, and buying Avalons as swaps are quite uncommon and hard to escrow for.

For anyone that cares I will be offering a S4/S4+ Water block, and Kit in the coming weeks I just need to get the engineering sample.
Let me know if anyone wants in I'll have 100% pricing with in 2 weeks.
Im down for this.... Anything to reduce the noise so i can run all day & night at full speed.... I have to turn my miner down at night to the lowest speed & then use smits fan hack to slow it down more so i can run it at night.... Mega painful PM me with details asap.. Do u have a price estimate on these?? Plus shipping to Australia?? $30 cost to make so expect a margin + shipping to be considerable. i have a PSU dps2000, so watt are not the problem.
could it be possible to have the firmware Oct-16 "powered" with other cgiminer ? or other Smit firmware able to overclock ?
I remember to read something , but i can not find the post detailing this info.
If you want to put a newer cgminer on, it will get cleared every time you power down unless you get him to make you a custom firmware with new cgminer loaded. I'm not sure what other changes this may affect, nor your ability to overclock on October firmware with very new cgminer. |

Why Don't you just do 480 posts and then just leave this account until it becomes a Hero Member  In part because that's not how activity works. |

Dear
could I get help for my S4.
Miner Status is showing a temperature ASIC value of 0, other 3 values are OK. how could I fix it ?
Other question... I want to overclock, so what firmware must I use ? I readed only Oct-16 firmware is able to overclock.
but is there other posible solution ?
thanks
Most likely nothing you can do about the temperature probe. Overclocking will benefit from the 20141016 firmware, I've got a copy if its not still hosted. You really don't have much headroom on the stock PSU though and that will be your limiting factor. |

Someone made a thread recently they are on a bidding ward to buy spoondoolies?
Is this true?
or am I just reading more troll stuff, and if its true, then why would spoondoolies sell their company?
Probably just random noise and per the announcement it would appear that they've merging / been bought by another company already. As to the final legal structure Guy will have to go into that. |

First of all, sorry for the large pictures..  In the future you can post small pictures with the below code: [url=http://imgur.com/MlA9emz][img width=400]https://i.imgur.com/MlA9emz.jpg[/img][/url] Example:  |

I hope they are not a scam. Chances are 50\50 now  I will visit their office as soon as they actually have it in stock before I buy any You might even want to consider taking a working device with you at that time. Kinda like the old COD (Cash On Delivery) model for items. Or like a real store where you buy stuff and pay for it at the time you pick it up. Has there ever been a miner vendor like that? Rockminer tried a program which would put demonstration miners in lots of shops, but it was closed after a while. |

Looks like 430 WITH shipping to US is best price I can get out of them. Wanted to get it to under 400 to make it worth it, considering you can get a single S5 shipped for 390...
At matching prices the Avlaon4 is extremely well matched to the S5. Higher power consumption but higher overclock, more flexibility and auto voltage. And as nolist3d said, no need to mod it to keep it in the house. |

i'm curious how many wb i can make with 1400...
i can buy cooper sheets 5mm thick, i can make the channels or look for a cnc
braze it and test it at above 200psi!
1k for a sheet of 1m*2m*5cm 90kg....
Get it in 10mm sheet, then you can sandwich two halves together with a basic gasket in the middle. Route / drill a channel into each half and you've got yourself a block. You only need half the block to be copper, the part touching the chips, the other half can be acetal, either clear or black. His intention wasn't to get cooling improvements from the copper, it was to make the channel in contact with the fluid be copper / not aluminium. |

Do I need to do anything else than pluggin in the power? No leds, no fans, nothing.. plugged in at 220V  Correct, see my response from the other thread: From the PSU guide for no PSU fan and no output: 1. Make sure the AC input wire has a good connection and the plugs are connected firmly
2. Make sure the mains power is working well and its voltage is above 205V.

Got a S4+ today, new in box. But it doesn't power up (no leds flashing, no fans, nothing)... I am in Switzerland, so it's 220V and they say it should work if higher than 205V.... Any suggestions? Thanks Try to open the case & tighten all of cable connection From the PSU guide for no PSU fan and no output: 1. Make sure the AC input wire has a good connection and the plugs are connected firmly
2. Make sure the mains power is working well and its voltage is above 205V.

IIRC only Newbie, Hero, and Legendary members don't get demoted normally. Maybe I'll fix it at some point, but it's not really a big deal.
True on it not being a big deal. But also fun to finally have the question answered. I wonder if those ranks don't demote normally because of some aftermarket changes you made to them or something else. Yeah, I actually put this thread in my calendar to revisit it and see the outcome  Was worth the wait. |

Most of the ones I used were very cheap or free after rebate fans. They worked fine as long as noise is not a issue. SP120s are overkill for a C1, especially for back side fans. I also used cheap and cheap fans on the back side and it really reduced temperatures. That unit was being fed very warm air in though so those with normal ambient might not see any drop. |

It was above 94° in my backyard shade yesterday so I dialed up the C1s' pump/fans power supply to 12.45vdc, perhaps higher. Some time in the middle of the night the supply failed. This morning one C1 was running one not, the one running had a highest temp of 80°C. The two C1's are in series cooling. Shut them down, swapped out the supply, and they are both up and running normal speed and temps. They've only been up 9 minutes so it might be too early to tell if they're both okay but looking good.
My mistake, both were down according to the pool. Perhaps a board hit 80°, hashing stopped but the recorded temp remained?
That's what happens when they hit 80C, they'll freeze and the status page will usually remain as it was when it froze. 80C still isn't that hot for these chips and the rest of the board components had the fan going so shouldn't be a problem. 80C is just an arbitrary "well if you've got this hot, you need to come check something so I'll stop here" point rather than "damn, we melting". |

Just to update about these things, the fans, they are not 80mm fans, they are in fact 72mm fans, went to replace one of them that lost 2 blades, lo' and behold, 80mm fan out of a psu does not fit. now to hunt out a smaller fan.
Oh, hat are these 6 pins next to the USB port, is that rs323? and what pin does what?
kinda need that info after plugging in 2nd "new r-box" onto the system and the 1st popped its usb to serial chip (it will not be seen at all via usb again, how i know its fried? it leaves 1st degree burns when touching the chip)
Fixed, remeasured and they are indeed 72mm which is pretty uncommon. You could screw a 60mm into one corner if you can't get hold of anything larger, or strap the 80mm external to the case. Which pins are you looking at, can you mark them on this picture? |

When I first purchased my S5 the hardware errors were very low (circa 100 in 24 hours) and as time has gone by the amount of errors has risen considerably as noted in the attached image. First of all, is that amount normal/safe?
Yes that's perfectly fine, its 0.005% of shares, ie 1 in 20,000. And secondly, I know hardware does degrade over time but I've always kept mine in the 45-60C temperature range so I'm curious to know whether it's common for miners to degrade after a period of say 6 months to a year?
While we don't have much historical data, if they get past the first month then the majority of stable hardware will outlast its utility for the most part. |

While were are taking about the repurposing of threads in HARDWARE...
CK can you move all the Antminer / Avalon SUPPORT threads to the MINING SUPPORT section?
Since we are talking about whole threads being not really about HARDWARE anymore.
No. Without a dedicated hardware support section, it's flexible enough for hardware announcements and discussions to turn into support threads, even though there is obviously then crossover with the mining support section. Competitions have previously been problematic though and I'd rather avoid that mistake again. The mining subsections are historical in development and no longer ideal but despite discussing this many times over we've been unable to come to something where the demarcation is clear enough to warrant a respin. I'm happy to discuss it again in meta/ if you wish to. Hey guys, we know the rules now, we will pay more attention in the next time! Good attitude. Also, I don't think its a bad idea to leave things which possibly shouldn't be in hardware long term, to get a soak in hardware. For example the 2 days or so that the competition spent in hardware was perfectly fine and allowed it to get attention from the correct people. |
