Thank you, that's a very useful guide.  |

Each block is stacked on top of the previous one. Adding another block to the top makes all lower blocks more difficult to remove: there is more "weight" above each block. A transaction in a block 6 blocks deep (6 confirmations) will be very difficult to remove.

Hi Guys I just got my antminer s3 and having big problems. It's only mining at about 250ghs and gets around 75% hw error. I am using a brand new Corsair CX500 and have also tried with my Corsair HX850. I have changed the thermal paste on all the chips. I have flashed it to latest firmware. I have very stable internet connection. Anyone have advice for me? After 5min:  After 10min:  HW error:  Hi, If it were me, I would do the following moonshots before going the drastic RMA route: 1) Base miner performance on at least 1 - 2 hours of continuous operation. 2) Consistent with 1) Try at least 2 other pools like BTCguild and eligius. Try both european and US servers. 3) Compare the S3 hash rate with the pool hash rate 4) Don't take your internet connection for granted. Go over to a friends house with a different internet provider and test and use their CAT cables if you can. It's easy to break the cable connector clip which retains the plug. 5) Get a DVM and measure the wall plug voltage. You may have some sort of voltage sag. 6) Finally, in the US you can buy or borrow a cheap LED plug which tells you if the wall socket is properly grounded. Borrow the equivalent gizmo for the UK.

I was able to seperate the above frequencies into smaller incremental steps, but I have no idea how to calculate the "reg. value" or the "ideal delay" for them. Anyone with a little more know-how than myself willing to help out? I know a few other people in this thread were looking for something like this as well, and any help at all would be appreciated. Thanks!
dude this is great really great thanks I added more in bold and here is a little reminder for us well for me. vi /etc/config/asic-freq |

Finally got this setup finished. Built a custom server room in my pole barn to house all the ants. I figured they would run nice n cool with a small air conditioned room and the ants exhausted out the back. but that doesn't look like the case. I'm seeing temps on most of them up around 47 and 48 degrees even with the ac on high. I'm not sure if it's because all the PSU's are so close to the ants that it's sucking in the warm exhaust from the psu's, or just need a bigger AC, or maybe something wrong with the airflow of the room. The ants are creating suction in the small room, so much it whams the door shut and there is a noticeable difference in the sounds the fans are making while the door is open vs the door being shut. When it's shut it sounds like a vacuum when you put your hand over the hose. Is 47-48 not OCed still acceptable or should I worry about getting them down and suggestions on doing that which doesn't require moving the Ants.  I think the room is supposed to be sealed instead of having ants pull air off it. Your ants should warm the room while the AC cools it back keeping the set temperature. |

Do any of you here know why the queue on the config is set so high? Is there a big gain from setting it to a lower number or why did they program 4096 as the queue. The discarded amounts are so high...
Any idea? |

Any idea? Not sure, but what I can say is outside adjusting the freq and timings for overclocking, there's really nothing else you need to adjust or change. That being said, if your discarded shares are quite high it might be worth resetting your Antminer via the reset switch inside, and then checking your network for stability and throughput. |

Hi everyone ! I overclocked my s3 to 250 and it runs very well. I was wondering : should I go a little higher ? Is it possible? Could I get more Gh/s ? Does anyone do that and can tell me how to do the same if it works well ? Many thanks ! |

I've noticed one of my units is just bad. Hard to maintain 400-450gh/s with anywhere between 212-250. I've tried the old and new values, above 225 I will get a X on chip.
I'll have to play with 212-218 and hope I can get over 400gh/s

Is there anyone here that can post what PSU they have and if its powering an overclocked antminer s3?
I am a dumb girl that can't figure out this whole PSU situation
I can't choose between a CX500, CX600 or CX750 per antminer.
The cost between those power supplies are quite a bit for me.
HELP!
WHAT CONFUSES ME IS THAT SOME PEOPLE SAY I SHOULD GET A PSU WITH 4 SEPERATE PCI-E connections.
SOME PEOPLE SAY THE ANTMINER S3 will overclock well on 2 SEPERATE PCI-E CONNECTIONS.
I can't choose!
I only have two AntMiner S3's. With them OC'd to 250Mhz, using only one wire bundle gets very warm, so I think over time, this is a problem, so I connected two. I am using SVGA Supernova NEX650 G1's, one per miner and had hoped to do 1-1/2 miners per PSU. A good guide is here. https://bitcointalk.org/index.php?topic=486121I used this guys video too. https://www.youtube.com/watch?v=iuBvGUT6VM8I know it is the S1, but it has similar requirements, and his information helps make a choice. Since I cannot get 1-1/2 miners per PSU, I will probably upgrade to something with more capability or downgrade to something cheaper. |

Same happens on the PCB - it gets warm. Told you it will happen This is exactly the reason why you should have four cables, not just two - high amperage will heat the wires/connectors. |

Antminer S3 manual says pools can be setup in three ways, Failover, Balance, Load Balance.
As per my understanding, Failover is as earlier in S1 and it priorities pools from the top to bottom.
The Balance as per manual is to share the mining power to each pools equally.
Now comes to the Load Balance or Quota based.
Anyone knows how the Load Balance and Balance configured The manual says "Change multipool strategy from failover to quota based balance".
But there is no place to enter quota to each pool. I interpreted wrong or I'm missing something?
Does anyone have an answer to this one yet? Quotas look interesting, but I just can't see how you set them. |

I think the room is supposed to be sealed instead of having ants pull air off it. Your ants should warm the room while the AC cools it back keeping the set temperature. The room has a problem in that The AC cannot pump air in at the same rate as the Antminers pump it out. Hence why the fans struggle. The AC isn't doing the job, and with that many fans you don't need AC to have a nice breeze. Just open up the vents instead, and hey presto. Also, try to work out a way to pump all that lovely hot air into your home. I'm quite serious. Why waste warmed air and burn fuel to heat your home instead? |

Here is the asic-freq file I made. I tried to make the wattage close to what you would expect on an 80 Plus Gold power supply. It would be cool if this format could be adopted and expanded upon with additional tested frequencies and re-posted regularly to this thread using the forum code tags. What do you guys think? * Edit: Make sure you convert line endings to Unix format if on windows. I just copied from forum into notepad++ and it showed "carriage returns". I haven't tested this file with windows line endings. I would expect that the forum code tags should retain proper line endings, but alas, they didn't. Not sure if it would make the bitmain scripts puke or not, haven't tested it.. You guys are all big boys, I just thought I'd mention it.  package 'cgminer'

I have 2 questions about the Antminer:
1. Does it matter if i only use 2 powerplugs instead of 4?
2. currently my miner only hashes at max 200GH/S is this due to the power or should i check the some other things?
Thnx in advanced

Try P2Pool. Like the one in his signature. Starts slow, but it's a really good payoff in the end. |
