I have finally found the "potential" problem with my miners. It should be because the difficulty the p2pool giving my miner is too low.
There's a feature in p2pool about setting difficulty: [username]/[pool difficulty]+[local difficulty]
Should I be setting these??? If so, what value should i give for a 1600GH/s Terraminer?
There are literally pages of debates on this very thread about the value of setting share difficulties. Here's the deal: Using "/" sets the actual share difficulty. Unless you set it over the p2pool minimum value, it has no effect. Using "+" sets the pseudo-share difficulty. All this does is make graphs look pretty. Bitmain has stated that you should set *some* value for use with the S3. They recommend either 256 or 512. Maybe it's something to do with their drivers and the way they handle work from p2pool's varying difficulty and restarts. Since nobody has the source code, nobody can do anything about it or make any kind of valid statement one way or the other. I have personally seen absolutely no difference in my S3s on p2pool either setting the values or leaving them alone. I do not own any Cointerra gear, so all I can say is for you to try it out. Put something like ADDRESS/1024+1000 and see what happens. I'm sure somebody will come along and try to say something different and ignite the entire debate again  |

Yes Pool Luck is an interesting topic. As far as I know, all the well know and large pool are "persistently" haveing 5~25% below 100% luck.
Almost never do they get over 100% for a reasonable period average...... I do remember the days when BTCGuild have a persistent 105% luck.
I was wondering, since most pool nowadays have below 100% luck (and that luck of everybody average out must equal to 100%), it must be either:
(i) pool stealing, by diverting part of the pool mining power to another private pool; or
(ii) some other secret miners / pools / hubs, were able to mine with a more efficient implementations, thus having some kind of statistical edge over the other major pools; or
(iii) miscalculation of some kind?; or
(iv) act of god ... really ... everybody is bad luck ....
I also recall to have read from the news that a professor published a paper, suggesting that the larger the pool, the more feasible for it to implement a kind of mining strategy where after it has mined the block, it withhold broadcasting it while working on the next block, and only boradcast it sometime later, so as to give itself some kind of head start with the next block, because without being broadcast, other miners will keeps on stupidly mine on the same block where indeed the block was already taken by the stealthy pool .... pool luck has become suspecious and all pool's luck drop soon after that news. Coincident?
Luck is luck. It's neither good nor bad, it just is. You are incorrect in your assumption that luck must average to 100%. It most certainly does not. Luck is simply a measure of how long a pool took to solve a block vs how long it is expected for them to solve that block. The calculations are based on probability. It's the same calculation used by online calculators to figure out what your ideal expected earnings are: Difficulty * 2^32 / hash rate = expected number of seconds to solve a block
Because of the nature of mining, you may be over that time, or you may be under it. It's not some super-secret organization or pool operator maliciously commandeering miner's hashing power for nefarious reasons. It's not stealing, or diversion of resources, or miscalculations. It is just luck. If you truly feel so strongly that there is something going on out there in the pools, you're very welcome to start your own and mine on it. |

Thanks for the information, that's very helpful. DNS aside, latency in the communitcation between the miner and the pool(s) will have an affect on the number of accepted shares, correct? Although it may only be negligible at times when the difference in latency is only slight, it could lead to almost completely wasted time and energy if the difference between two pools is significant - e.g. two pools: one at 50ms, one at 250ms. EDIT: to clarify, it would be a waste to mine at a pool with a 250ms ping, compared to the one with the 50ms ping.
Yes, latency is an important factor; however, it is not the only one. Using your example, I'd mine at a pool with 250ms latency and 0% fee vs the 50ms one with a 5% fee. |

You don't need to download a local wallet for namecoins to merge mine them. I just send mine to an exchange such as Cryptsy or BTC-e. I frequently Exchange them for BTC so I'm not worried about losing them if the exchange vanishes. Namecoins add about 1% to your total. DVC and IXC add virtually nothing and will never amount to much unless you're mining with multiple PH.
On the other hand, never use an exchange address for your mined bitcoins. Always use a local wallet.
How are you merge mining NMC? Are you running your own pool with your own custom code to do so? To merge mine any coin along with BTC, your pool must be able to call getBlockTemplate and generateTransaction for each of the coins you're merge mining. It needs to look at the current coin's block and see if the share being evaluated will solve that block. It's not just point to some wallet address, or you could merge mine every single SHA-256 coin out there. |

Any other cool funky ways to use it? I'm sure we have a clever community here which will know some funky ways to use them .
I have though of using it to crack password, is it possible? No. How about using the exhaust for drying wood or perhaps to dehydrate food (make your own beef jerky)? |

DNS servers do not have anything to do with latency, there only job is to take your web request ie: www.google.com to an ip and make the connection, once done they are done. Now having a good dns server with a faster response time is key when opening web pages and waiting for web pages to load. As far as mining the dns would only have less then a second of interaction find your -o ip address to real ip and making the connection (basically dns is the guy who hooks you up with a blind date), once you two meet he is out of there. Icon Yes response time of the DNS server itself is crucial but if it takes you 200ms to get to the DNS server instead of 10ms that is an extra 380ms of time wasted. That's latency. |

OMG! Why not P2POOL！  Sure looks like somebody screwed up and put things in the wrong place:  Whoever did it must be kicking themselves right now. Phaw  Forgive me guys... I dont understand? (please) Also now that we have moved to the 9M range I have been getting more shares and almost no orphans or dead...? 1) he paid 27 BTC in fees. He should have only paid 0.0001 BTC for a transaction of that size. 2) you're having a streak of good luck. |

And there it is... Share difficulty breached 10M.  |

Anyone know anything about these folks: http://eliteasic.com/ eliteASIC? They list a couple SHA-256 miners with competitive specs for power/GH and $/GH (2.2TH/s and 4.4 TH/s). It appears they have been around only since March of this year. Google and searches on here haven't been very helpful. Most of Google's hits are from the company. First post, so Hello everyone Hello and welcome. Do NOT send your money there. There is no such miner. Even if there was such hardware, the prices are way too high to be competitive. For example, the Spondoolies-Tech SP30 is $3895 for 4.5TH/s. You won't get one until the end of September/October, though. There's a list of hardware manufacturers compiled by dogie. Take a look at it here: https://bitcointalk.org/index.php?topic=456691.0. Thanks! Yea, I had already checked the links given earlier in the thread. Just wondered if those folks had just come on the scene or something. As compared to the Sp30, their Aristocat is listed at about $.50 more per GH, but it has a claimed W/GH about .04 lower. And they claim to be shipping within 5 days of order. 4.4 TH/s this week might be worth the extra cost to some? All of this is based on their claims, and my math though, and I wouldn't bet any money on either Obviously if they are not a real company it's all BS anyway. Thanks for the reply! I'd put far more faith in your math than in some vendor pretty much nobody's ever heard of claiming to have a 4.4TH/s miner shipping today |

I did a bit of mining 2 or so years ago now and I managed to get 0.5 BTC and I've been looking getting back in with the Antminer S3. But the calculators I've used predict that after 7-8 months I'll be running at a loss, so what's the deal? Is it a case of reinvest a large chunk of your profits into new machinery to keep up and make some money on selling old hardware? I've read a ton of threads and there seems to be A LOT of negativity about mining, but if it really is the doom and gloom some make it out to be surely they would've just left the game and just cashed in on their hardware and not carry on?
Have we really reached a point now where unless you've been doing it for a while or can put a large amount of capital upfront it's just not worth it?
Well, it really depends on what you mean by "worth it." You've already got 0.5 BTC. If you want to purchase an S3, you'll also need a PSU to run it. Right away you're spending more than that 0.5 BTC. Right now, the S3+ is 0.58 BTC and has an MOQ of 2 units. You might find some local resellers who will do one unit at a time, and if you're already got a PSU, that's good, but if not, more coin out of your pocket. Once you figure out how much you're going to spend up front, and how much the unit(s) will cost you to run ask yourself if you think that S3 is going to earn back that and more. If yes, then go for it. If no, then don't. I've bought and sold hardware and mined with it. I'm ahead of the game, so it can be done |

I agree with you. People that talk the most on this forum are bears.
Every single day I have to read posts like
Don't invest, mining is dead!
Don't cloud mine, all cloud mining is a scam!
Bitcoin is dying bail out!
Every f... single day!
Don't invest, mining is deadNo it isn't. This reaction is just a typical knee-jerk one from the community because 99/100 of the posts asking questions where that is the answer are, "I just read about this Bitcoin thing and I wanna be RICH!!!111!!! I gets free power cuz I live in my parents' basement!!!" Don't cloud miner, all cloud mining is a scam!No, not all cloud mining is a scam. There are truly some legitimate providers out there. However, you as a customer have virtually no chance of ever making any profit. Cloud mining companies exist to make themselves profit. Not you. Bitcoin is dying bail out!No it isn't. Bitcoin is just getting started. More and more businesses are beginning to accept it as a valid form of payment. I can book a fight, stay at a hotel, rent a car, eat, buy merchandise... all with Bitcoin. Heck, I can even rent vacation homes with it. |

Hello! I have My own power source (solar and wind) should I start mining?
And if so what should my first purchase be?
Do you generate excess power? If you do, take a look at how much you can earn by selling it back to the power company and compare it to profitability of mining. If you don't, then you don't really have your own power source for mining since you'll need to obtain the excess power needed by the rigs from somewhere. |

You've been registered since 2011 and barely have 18 posts. Either you like to read and withhold commentary or you have been oblivious as to what has transpired over the last 3 years.
Type out your costs and your revenue and we'll show you where your math or assumptions are incorrect.
i do withhold i don't really post much so what ? i have 1500gh/s @1000-1100 wats its .09-0.01 cents KW/s i make .1 every 2-3 days on BTCguild i pay 250 for the whole house Assuming your mining gear has completely paid for itself at this point, and your only expenses are the power it consumes... If you assume 10% difficulty jumps, you're looking at getting another 3 BTC or so before it costs you more to run the miners than they produce. If you assume 15%, you're looking at about1.96 BTCIf you assume 20%, it's about 1.45 BTC |

I've been watching the exchange rate go down over the last couple of days, that must have a huge impact on large mining farms not holding the BTC. Playing around with mining calculators does not make any sense (well, it never really did) with unpredictable difficulty increase and exchange rate, but what the heck, I'm still considering investing in 6 or 9 S3+ (multiple of 3 to have each 3 on one EVGA1300) and buying some BTC (10 should do, this is a gamble, no serious investment, I've had worse luck with some stocks). Although the SP30 (despite the higher purchase price ) would make more sense in the long run due to the lower energy consumption it pretty much is out of the picture now, because one has to think of selling the hardware off once not profitable any more, and a bunch of S3s is definitely easier to sell than one SP30. With the ROI calculations not considering the selling price of the hardware it should nevertheless be possible to reach a positiv ROI because used Antminers just sell. What I have not found out so far: If you place an order at Bitmaintech, when do you have to pay? Orders placed with Bitmain must be paid in full within an hour of placing the order. They only accept BTC, and when you place the order, you're given a BTC address to which you will send payment. |

I know it's already been said, but it bears repeating: just because you are not paying for power does not mean it is free. Your parents are paying the bill, and if suddenly they've got a bill that's 5 times higher than what they're used to seeing, guess who's getting in trouble? If you really want to try mining, keep the best machine of the bunch and mine some CPU coin. Take the profit you get from selling the rest of the equipment and buy some BTC.
Definitely talk to your parents before even thinking about mining. They will most certainly notice the very large increased usage of electricity when their bill comes.

I didn't know that internet connection makes difference in mining. Have you compared your results with the other kind of connection?
The idea of higher communication time does lend to the loss of accepted shares in that if someone else solves before you then your share will be rejected - essentially, it's a first-come, first-served practice. I am looking at it as reducing any bottlenecks, which I have (limited) control over, and got out of a pool which had a 200ms ping and into one of only 50ms. The longer it takes to get the information, the longer it takes to submit shares. Just like a delay for one race car in a 1/4 mile race, all things being equal (car, setup, skill), the one off the line first will win. No, I haven't compared, directly, or tested. I'm not sure how I could test this myself. So, you made it 4 times faster. That's a big deal. Isn't it more expensive? opendns is free. That being written, you might want to benchmark your ISP's DNS server against using opendns. Grab namebench and run it to see what it gives you back. When my ISP's DNS servers crapped out, I changed to opendns, only to change back because of the latency introduced by opendns. |

Thank you, gonna check it out later, interesting stuff It's really good deal. Bully for you!  Great way to get into mining. Even though a single miner like that won't make much, it's still a great start!
Nice hobby I hope to have this one Thank you guys! knightdk: I followed a simple guide, if one day you want to try it out yourself here you go: https://antminers.co.uk/antminer-u1-u2-raspberry-pi-setup-guide/I got into mining a few months ago with a single Antminer U1, plugged into my windows server with bfgminer...
Now I have an RPi with the same U1, 10 Gridseed Mini's, and an Antminer S1 as well... not likely to ROI any of it.. but if prices go up, might be cool.
Really? Sound really cool, i was wondering how does the Pi works well with Gridseeds and Antimers like the S1, S2 or S3? Thank you  Also, i'll leave here some screenshots from the web interface of Minepeon: Ammount i made in two days of mining with a single USB Antimer U2:  Antminer U2 stats  General graphs  Welcome to the world of mining! The rPi is a great little controller. I use one for some U2s as well. They work very well with the gridseeds, too. The other miners you mention: the S1, the S2 and the S3 all are standalone devices. They have their own controller boards built right in, so you just plug them into your network, power them up and configure them. If you end up with multiple miners and don't want to configure them all individually, the rPi can be used to run a proxy. That way, you just point all of your miners to the rPi, and only have to do it once. From that point, any changes you wish to make (for example, switching pools), you just do on the rPi. By the way, MinePeon is a great choice. It provides a lot of useful information in a very easy to read interface. |

I have a computer with Windows 7, bitcoin core downloaded and updated, p2pool downloaded and running
I have a dynamic IP internet connection, and a Cisco router.
I have in my network the computer (node), and a cointerra machine
Now I want to connect my cointerra to my computer node with p2pool running ......
How should I set it?
You just set the pool to the IP address of the windows box that is running the p2pool node. For example if that computer has an IP address of 192.168.1.5 you set the pool to http://192.168.1.5:9332. Use a bitcoin wallet address as the username and a password of x. |
