When solo mining is your miner on non stop for the full year or did you reboot in between to clear HW errors. does rebooting add to your time or does ckpool remember where you were last
What do you mean, add to your time? There is no progress toward finding a block in the first place, therefore it does not matter if you restart the miners all the time. |

Did you try a different PSU? Coolermaster is rarely a brand you want on any electronics. Its quite possible that it could cause the miner to crash or damage hardware. Its also possible your controller just went dead.

you can change your fan, if i'm correct the s5 mount 120mm, you can some artif fan f12 or the one with the pwn and install that instead, i've done the same thing with those scrypt miners, and they working fine, and were very quite
or you can undervolt it, but it require a little of experience with electricity
yep, he can always undervolt it, but process seems a little bit complicated, i dont know if this is your case or not, but here you can find a guide about how to do it with an S1 -> https://bitcointalk.org/index.php?topic=526060.0i hope it helps you  You can not Penmod a S5, however. My tip would be to set the fan down to 25%-40% depending on the ambient temp. At 25% they are pretty quiet imo. I think this is the way to go. If it's nice and cool those fans don't need to be running on beast mode  Today i tried something new, i stripped 2 S1 fans and put it on the S5, i was able to lower fan RPM from 2560 to 2160 + drop the temp by 6c. The noise/cooling performance is unreal compared to a single fan. Now the only thing i can hear is my S4 that seem stuck at 2520 RPM atm. |

stick a piece of paper in your wall
This is actually not a horrible idea. I cannot remember the spy movie but they did this. What they did was had a vent or something that allowed a straight drop of item and used magnets. So say you stored your paper storage in the wall with a magnet on it. You use a string with another magnet on it and you can "fish" it out when needed. Only problem is fire etc that destroy it. Safe's do not have the fire issue assuming nice safe. Isolate it with good metal, then covering that with aluminum that the fire does not destroy etc. Since you have access to the wall that would not be problem even if someone will start destroying your house. Another place to hide the paper wallet i would consider blank pipes(10cm extension) in your water installation huh? Covering it with aluminium would not change anything, the heat will still be transferred to the paper and thus all that will be left is dust. You could print the key with metal or some such, but the best thing to do is definitively have several backups. I don't know how is it called in english but firefighters use them. It is against fire and it can protect the paper too from the fire. Having several backups is the best idea for everything not just for the paper wallet but also for sensitive files/data, another idea? There's flame retardant and you can stack them together in a hard enclosure, common in flame retardants safe. But they only give you time, meaning if you do not extinguish the fire quick enough, the content will still burn. Instead imagine a steel QR cube. It could be grabbed easily with magnets too! I mean the material that firefighters wears, it's something aluminum. So that can protect the paper wallet from the fire. But it is recommended to have more than 2-3 backups so this is not enough. Like i said, there is only fire retardants. Thinking you can Fireproof it by covering it is a fallacy. Everything has a melting point so you can't protect paper from fire indefinitively unless you put it 6 feets under. |

I hear bankers saying we don't find bitcoin interesting , but we are interested in blockchain technology. Which I find a paradox...
Of course you don't like bitcoin because you lose the power to mint it yourselves. You would rather use blockchain technology and start an altcoin yourselves.
They don't want an altcoin, they just want to use blockchain technology for storing ledger information, verification, archiving, authentication/validating signatures. An altcoin is pointless to them. The Coin is just one possible application of this great technology. This is the whole point. People seen to forget that a bank is a hell tons of servers that need to share data, have consensus and other distributed service problems. And the blockchain solves them pretty well. Pretty much, they could eventually move their data infrastructure to use a blockchain-like validation method, i'm just not how sure it will be changed, since there is not much need to get a miner fee, stable block rate, etc. It would make tracability and falsifying data harder. And more verification steps could be handled by a machine, less by a human. The other thing i'm wondering is how they would want to add correction to transactions. Chargeback, etc. Since the bank would be owning all the keys, they could force any transaction from anywhere to anywhere. The difference here is it would be properly logged. |

Under file it should have "Write offline transaction" and "Put offline transaction online" or something along those words. Already has sign/verify message, sweet feature.
pretty sure bitcoin-armory and other high security wallets have this feature already. Yes lets push MORE people to abandon full nodes................ We are having a node issue and the idea to helping out is NAH FUCK THAT USE SOMETHING OTHER THAN CORE, It's only for the bare bones.. but becaues of that no one uses it... and we have a node problem.. but we don't want to change it because other wallets have those features so use those wallets.. but use the core because we have a node problem but don't use the core cause it's bare bones.. DO we see the circle here? Having Bitcoincore does not mean you're running a full node. And we don't have a node problem #. The pseudo problem with nodes and the hashrate is its centralization. Also i wouldn't run a full node on your active wallet anyways. Best use different wallets for that. |

I think I will hold my Bitcoins. What exactly is the The 21 Bitcoin Computer? ( http://www.amazon.com/dp/B014RD021C). Is it like the stand-alone Bitcoin node that Bitnodes was offering, except this one has no screen? EDIT: https://21.co/learn/faq/#what-is-the-21-bitcoin-computerWhat is the 21 Bitcoin Chip?The 21 Bitcoin Chip is an application specific integrated circuit (ASIC) specifically designed to provide a constant stream of bitcoin to your computer as a system resource.Funny! Is that for real? A mini ARM PC just like the Arduino or the RasPI (20$) ends up being 400$ because it comes with some software on it based on open source code? Just wow. If that sell, some people here will make a killing making a image of a RasPI with a pre-setup bitcoincore/mining node where you just need to slap or generate a wallet.dat on it. All they have to do is copy it to a cheap RasPI and they make 2000% return. This is called Magic of Marketing. They add value through awesome packaging. 21.co CEO is an awesome marketeer. I don't know if its good skills as a marketeer or how oblivious/impulsive the consumer base is. I suppose it works for people that do not care to spend their money efficiently. |

The biggest longer-term factor is that ASIC technology for Bitcoin is getty very very close to the current state-of-the-art - which means that "new generations" of ASIC won't be happening on an every year basis any more, past the final jump to full-custom 14/16NM that will probably happen next year, likely late in the year.
I suspect 2017 will show the lowest diff increase rate and greatest stability of difficulty of all time for Bitcoin, after a wild ride the rest of 2015 and most or all of 2016.
The next 6 (and 12 and probably 18ish) months in Bitcoin mining look to be "interesting times".
Sounds like you think the price will remain stable? What would happen to your 2017 prediction if the market rate hits $4,000 in 2016? $4000? I doubt we'll see that in the next 20 years, much less the next decade or sooner. $1000? Perhaps within a decade, but doubt that will happen again before the end of 2020. the value of bitcoin is very predictable, now can you tell me, that you were expecting the 1200 value(the last ath) to be reached in 2013? i guess no, no one was expecting it 1k or 4k, are nothing if there are the right demand behind it, we can hit that on the next halving quite easily It never truly reached 1200, or 1000 or 600. It was false trade data ramping up the BTC value. The price value was based on false confidence, therefore it would be a fallacy to include the mt-gox portion of BTC history as a valid comparison. We'll be lucky if we're at stable over 300$ by halving. 400$ sound doable with speculative value of BTC raising due to halving. 600$ would be a stretch. Trust is only built slowly. |

Let's come up with solution better than this  nah. I think this is the best situation. I would agree with not moving it. No one mentions the problem there once was with people typing usernames VERY close to others and trying to scam. And majority were newbie accounts. So this stops someone from taking a user name from selling or auction and trying to phish some info or btc out of people. It is very nice. If you're not an impostor then this message doesn't apply to you, so no its just fine like that. This is the best way to protect everyone from impostors short of preventing new accounts from posting in marketplace and PM'ing people. Just participate a bit on the forum and it will go away. |

Thanks, appreciate it.
I did not enter receiving addresses in my address book. (What are those anyway?)
Does that mean I will not be able to get the bitcoin after all this?
If I download SPV wallet, will I be able to get some bitcoin tonight? tomorrow?
Thanks for your patience.
I hadn't realized you went in and bought BTC with 0 idea of how it work, even conceptually. Should read the 101 stuff on bitcoin.org; https://bitcoin.org/en/how-it-worksIn a nutshell, the blockchain is a super ledger that merely say which address control X bitcoin. The address looking like this; 1Bd5wrFxHYRkk4UCFttcPNMYzqJnQKfXUE Whoever has the secret privkey to this address can use any BTC sent to this address. When you have a wallet, your wallet doesn't keep BTC it hold the private key, that should remain hidden and for each private key it will give you a public address. Wherever you bought BTC, what you do is withdraw money from there and input an address you generated with your wallet. Then the wallet will let you send BTC from that address to wherever you want and so forth. |

I don't like how they call it Anonymous. Either they're misinformed about BTC or they're trying to make people feel at ease to raise their sales. But if you go about buying Bitcoin instantly with any electronic mean, then you voided your so called Anonymity.
I guess calling it pseudo-anonymous would confuse the common mortal.
Actually not sure if I would like to pay an escort with Bitcoin instead of cash.. there will be a transaction recorded belonging to you + an escort banging session, vs 0 recordings of that happening if you pay with cash. I don't really see the benefits to be honest. If only CoinJar, confidential transactions, Dark wallets and all that stuff got finished and properly working, then maybe people will be more prone to pay this kind of service using Bitcoin :p My thoughts exactly. In any sort of face to face transactions, there is much less tracability with cash, BTC is indeed not a very goo way to stay fully anonymous. But with cash withdrawn you still need to be somewhat careful. I'm pretty sure all banks log the bill serial numbers when you withdraw cash. Funny that BTC is being begged at a criminal's currency when there is so much tracability, meanwhile Cash is still the most convenient for criminals, face to face. |

That other supply of mine ran stable at 425, just shy of 1.4TH, but at an expensive 870W since it was running out at 12.65V. For some reason I figured a high % of HWE would actually degrade performance. I did have issues with hash boards not firing up under 11V, but I'll keep playing with it with that knowledge now.
1% HWE is huge for Antminers, at stock loads i get under 0.0001% error rate. But 1% is still just 1% of your hashrate wasted. Its not much if you're looking at a 30% efficiency gain. But with a good PSU, such as a EVGA G2/GS, seasonics, other high quality OEM, you should'nt really go above 0.1% even if you push it hard and i'd say thats rather minimal. I don't know about the stability of the servers PSU, sadly. But even if its not too clean power, again 1% isint too bad its 14GH at 1.4THS wasted. |

Thanks, I am in Canada too -- do you use quickbt.com?
No i used to use Bylls and do payments to my credit cards to "cash out" BTC when needed. Now i use Coinbase as they have a bit better exchange rate and the fee is 1%+1$ to sell and 1%+0.7$ to buy. Its also much faster. If you don't mind me asking, how much time does it take between sending the interac transfer and receiving the bitcoin to spend? Its supposed to be instant with Interact. A few days with bank transfer. Now the friggin program is entering a second phase, "Synchronizing with Network." Then apparently there are two more phases, "Build Databases" and "Scan Transaction History".
That first phase took about 8 hours. Does anyone have an idea of how long these three other phases will take?
Depending on your computer speed, it can be overnight or days. That is why a SPV wallet is highly recommended for daily usage. Takes a few minutes to sync fully from scratch. |

My power supply showed up and I've been playing with it a bit. Shit, you weren't kidding about the older ones not liking heavy undervolting. At what HWE% should I consider something not plausible as a combination of MHz VS Voltage? My supply can go from 9.3V up to 13.something (although for obvious reasons I'm not going to go higher than my other supply, at 12.65V)
Whatever. If you get 1% HW and you get a better J/GH or better performance, it doesnt matter. Its just that when you go too low or too high voltage for the freq, you will lose performance unrelated to HW. If you try to go down, just go down to whats stable and the best J/GH, if you go up, you might be able to stabilize 400-425HZ, it doesnt seem possible with stock. With a good stable PSU, i get very little HWE% however. Under 0.01% |

Hi guys my antminer s5 is dead, the beagle bone died (already did the micro sd reimaging thing, it didn't work), I don't want to wait 3 weeks and spent 62$ buying a BB from amazon when i have no bullet proof tutorial about how to make it work (and add 2 months to ROI).
I ask for your help because i had seen that the daughter board has two empty data connector for hashing blades and an empty fan connector.
So my question is, what does it takes to build a 4 blades s5?
A) Do I just connect the two blades and fan from my broken antminer?
B) Connect the 2 hashing blades, and intercept the fan cables of good miner and splice them with the fan of my broken miner?
I was wondering if there is no damaging side effect from doing this?
I have the Jan 07 Firmware, the one that came with the 5 machines.
Any help or advice that you could provide will be really appreciated .
Mine run fine with just plugging the blade cables into the S5 next to it. The only problem is the cables are short so you need to put them on their sides head to head. I use 1 fan per S5 so i use up the 2 Fan connectors. Then i put a box fan blowing air through the fins and it solve the clutter heat problem and it let me lower the fans to 25%. The biggest thing is firmware I cannot remember which one does it but only certain ones have 4 ports active. Others you can plug it in on hashing modules and it would do nothing. I would look through S5 thread and find out which one it right firmware. Then find someone who sales the cables and get longer cables so you can leave them in old case. With those 2 things you should be able to mod one into 4 blades. is there some reason that i am unaware of to not use the latest firmware with fan controls? Seeing how loud those things are without it, the first thing i do is flash any S5 i buy to the fan control firmware. |

Thanks again.
Stupid question again: where do I find my bitcoin address? Are these the addresses I put into Virwox and quickbt when I did those two transaction or is it a stable address for my wallet? Totally confused.
And how do I find the private keys?
You'll have an address book and you can generate receiving addresses. If you did not do this before, its absolutely impossible for you to receive the BTC on your wallet. Its like saying you bought a book online but didnt give them an address to ship to. I recommend not messing with private keys, whoever has access to them have access to the BTC "stored" on its public address. If you want to move your BTC to a new wallet, just make a new clean wallet and send it there. Thanks can't retrieve wallet because blockchain is downloading. It's only another 5 hours or so. I'm just going to wait. Thanks for all your help. Do you guys recommend interac over paypal for purchasing bitcoin? I find the other methods somewhat abstruse. Interact and bank transfers work well for me in Canada. I suppose if you find a way to buy BTC with Paypal, then that can work too since the one at risk is the seller, not the buyer, but i would suspect you would be paying a pretty hefty % to Paypal fee. |

This is kinda worrying that people can eavesdrop on our communications with any site, but it doesn't seem to be very prevalent. It isn't something that makes up a majority of the sites visited, so I don't think this particular vulnerability is worrying.
I think the NSA has better things to do than monitor everyone's International use of Bitcoin. Until your TX's are linked to suspected terrorist/criminal activity that affect the US or international policies in any way, i think you can put down the Tinfoil hat. |
