Chinese and some other miners mining empty blocks is a bigger problem IMO.

So, i can't have a regular mining with my asics, it's right ? I'll read more about solomining, it can be more interesting than pool mining. I come back when i know more about this, if you have more solutions, i'm open for it. Thanks you a lot  Well you can of course, but it is not wise due to the very very low profits. That's why I would go with lottery and point it to solo mining. |

How much btc could you mine a day with an antminer s1? And how much cost these things nowadays, I am possibly interested in starting an mining operation Short answer. Don't get a S1 if you don't have "free electricity". I can get free electricity if I want  But how much do antminers cost/earn a day? So I am able to calculate my ROI. There is several calculators which may help you to estimate your profit, but it isn't exactly easy because the difficulty keeps rising. And block reward halving is coming. http://tradebtc.net/bitcalc.phphttp://www.coinwarz.com/calculators/bitcoin-mining-calculatorIf you want a cheap, used and quite silent Antminer, I would go with Antminer S3 rather than with S1. If you want a cheap used Antminer and you don't care about noise, I would go with Antminer S5. If you want a cost-effective, power efficient and new Antminer, and you don't care about NOISE, I would go with Antminer S7. If you want a cost-effective, power efficient and new miner and you want a reasonable amount of noise, I would go with Avalon 6 (though it isn't as cheap as S7). See Ebay and Amazon for old Antminer and Avalon -miners.

okay here is what you do.
run ac right into the intake
make sure the fan that blows the air outward is not restricted. So make sure the exhaust is vented out of the room.
Step one
set freq to 700 fan to 70% make sure the psu has 12.5 volts not 12.0 volts
Step 2 fire it up
run it for an hour
check temps should be 50c or less
check fan speed should be 4200 to 4600
check errors should be 0.0025 or less
step 3 jump freq to 725 fan to 70% make sure psu has 12.5 volts not 12.0 volts
step 4
run it for an hour
check temps should be 55c or less
check fan speed should 4200 to 4600
check errors should be 0.0030 or less
keep that pattern of increase.
when temps reach 62c stop
if temps stay under 62 c and errors get to 0.200 stop
a fan setting of 100% is not necessary top rpms are about 4200 to 4600
you will get them at 70 to 75% fan setting
I have never seen an s-7 get past freq 800 so good luck at doing better then that
this over clocking voids warranty
Thanks man , How can i check the voltage? Start by learning some basic electronics. It is dangerous if you don't exactly know what you are doing. |

Maybe more like 2013 model.. There was no Antminer S1 back in 2008  And bitcoin was released in 3 January 2009. 1. Overclock it to 393.75Mhz. This gives you about ~195GH/s. Works great for me. Make sure that your PSU can handle it ( I recommend min. 500W PSU) I'm only holding on to my S1, because I can possibly use it when community miner boards are available. Good DIY skills are needed for this. https://bitcointalk.org/index.php?topic=1368507.0S1 is not very profitable any more, unless you have "free electricity". 2. Kano CKPool https://bitcointalk.org/index.php?topic=789369.0 www.kano.isClusters burn at that speed without extra cooling. I have plans to build new mining power. Well I'm looking at my temps right now and they are reasonable. 57 C and 55 C. So nope. |

You mean this?  Don't worry, you won't run out of memory.. It doesn't work in the way that I guess you are thinking it works. |

Yes looks like both sockets have been overheating due to poor contact of the pins. This will have been made worse by the Daily plugging and unplugging. I would look for a way to have the Miner plus permanently connected and an additional plug / socket arrangement for the swapping.
One thing that is strange is that the problem has only occurred on the 3 Gnd connections and not the 12V. This may indicate that the PSU Gnd wires have been made up with a different batch of socket crimps that the 12V ones?
Rich
Yeah think of the unplugging and re plugging as fucking. Thus the name for the plug and jack. As male or female. With repeated fucking most female sockets get loose. The male pins do not suffer as much from repetious fucking just like real life. Crude analogy but easy to remember.  This is the best explanation in technical stuff that I've ever heard |

Hi All, My first post, so i will introduce myself... I'm Sara... Hi! There is a lot of information around, I guess the hardest part is knowing where to start without jumping around and picking up bits of info, rather than something more structured! I have bought an ant miner s3 used off eBay to get started with Are there any getting started guides around you guys would recommend? Thanks Quick instructions. -Get a receiving address from your wallet -Join a mining pool. -Create a worker on the pool -Find your S3 on the network (factory default is 192.168.1.99) and use your web browser to connect to it -Go to network tab and setup the info. I recommend setting the miner to another address in case you ad a second. Reconnect to the new IP. -Go to system tab and administration. put in a password. -Go to status tab and miner configuration. -Put in your pools stratum address, worker username and worker password. If the pool does not use worker passwords just put an x. -Save everything. -Go to miner status and you should see the pool showing alive and the miner hashing. If not reboot the miner and check again. That's it for an S3. By the way, what is a mining pool and what is S3? Pooled mining: https://en.bitcoin.it/wiki/Pooled_mining2. Antminer S3  Specifications:

Power Efficiency: 0.77 J/GH on wall
Power Supply: 12V DC

Yeah, it sometimes maybe gets a little too off-topic but I love the way fellow Kano CKPool miners support here each other in various things, hardware things included. It keeps the mining and pool hash rate at sustainable level or at least has a positive effect on it  I still have 3pcs 100USD discount coupons for Antminer S7 batch 15 for those who need it. For free. edit: I have now no coupons |

Another nob question.
I have 3 miners atm.
Obviously I can put all miners under 1 worker, or I can put 3 miners under 3 different workers.
Which method give me a higher chance of finding a block?
or it works the same either way?
Doesn't matter. Works the same either way. |

I'm giving away my Antminer S7 coupons to any fellow Kano CKPool miner who is planning to buy Antminer S7 batch 15.
I have 4 coupons in total.
edit: Still have 3 coupons.
PM me.
I'll update this when I'm out of coupons.
edit2: I have now no coupons

Can this product ship to Finland?
Kyllä, joudut vaan hoitamaan tilauksen tullauksen ja maksamaan arvonlisäverot koko summasta (tuotteet+postikulut). Ei tullimaksua, mutta arvonlisävero 24% ----- Yes, you just need to deal with the customs clearance and pay VAT for the total sum (products+shipping). No customs duty, but a 24% VAT. Ootkos varma että ei tule tullimaksua :/ ? Olen varma. Olen tilannut 1kpl S2 ja 2kpl S7 Bitmainilta ja hoitanut tulliselvitykset. --- translation: Are you sure that there is no customs duty :/ ? Yes. I've ordered 1pc S2 and 2pcs S7 from Bitmain and done the customs clearances. |
