What? How can you say such a thing? Past "luck" has no bearing on future "luck". If you tossed heads 25 times in a row on a nickel you may feel it to be a special nickel but it will still have a 50/50% chance of landing on tails or heads on the next toss (assuming it's not loaded or a 2 headed coin ie cheating).
You know it probably better than me, and you are right about the 50/50% chance of outcome when tossing a coin no matter what the past results were. But it's very subtle as you know, and if you consider a series of tosses, the odds of an "all heads" or "all tails" series is 1/n 1/(2^(n-1)) where n = number of tosses, or am I wrong? So the chance of having a series of n bad rounds is (twice) lower than n-1 bad rounds, or am I wrong again?  Edit: Ahem I always sucked at math. But you get the idea, I hope Yes I get at what you're trying to say. The chance of something rare happening twice is 1/rare as likely. Akin to having lightning strike a human being twice. But if you consider a human being who has already been struck by lightning, his chance of being hit again should be the same as you and me (assuming he doesn't have a metal scalp or something silly). So if the first run of bad luck happened, the chance for it to happen again is now the same as it was before it happened the first time. According to OoC the pool didn't exhibit anything that deviated significantly from the expected distribution. All you new miners missed BTCGuild's horrible 3 month run in middle/late 2011. So many threads were made accusing E of scamming/stealing. And 18 months later he has to increase fees to keep people away from his pool  People either need to spread their mining power, accept a 8-10% fee at a PPS pool, or just live with PPLNS/Slush/DGM based scoring. |

is "Unconfirmed Transactions" accurate?
Mine has been stuck at the same number for 8 hours, yet I see my earnings in each individual block if I go look
sorry to be so picky about this, but I have to earn back my mining hardware, in a limited time, haha
If you have the pre-paid perk enabled (My Account > Donations and perks, the "immediate pay" options at the end of the page), you are getting paid for every block as soon as it is found and gets at few confirmations (I believe, possibly just one). The last block that appeared in the block list when you posted was at height 237798. The block in the main chain (the "real" one) at this height was from ASICMiner, not BitMinter. Than means it was probably a stale block, and it still show as "processing" in the list until it is found to be stale. Maybe* this will happen when the next block is found, but as far as I understand, this block will never make it to the main chain and miners will not be paid for it (and it's perfectly normal because it yielded no earnings to the pool). So, basically, I think you have not been paid in the last 8 hours because of a very unlucky round (6 hours), with an unlucky outcome (i.e. stale), followed by another unlucky round (4 hours), and while I wrote these line, we found one at height 237825 (phew!). Now, the bad luck is probably going to end, and you will see your unconfirmed total increasing (it will be confirmed immediately if you enable the pre-pay perk w/ a small donation). Finally, if you're not yet aware of how PPLNS works, you had to "fill" the last 10 shifts when you started mining, meaning initial revenues were lower than expected. But should you stop mining now, you will still earn revenues until you don't have any remaining work shares in the last 10 shifts, so it's a "symmetrical" delay in payments when you start/stop mining. Hope that helps... tl;dr: We have been very unlucky in the last 8 hours. Keep mining and with some luck your earnings will catch up with expected ones. *edit: maybe => yes indeed! What? How can you say such a thing? Past "luck" has no bearing on future "luck". If you tossed heads 25 times in a row on a nickel you may feel it to be a special nickel but it will still have a 50/50% chance of landing on tails or heads on the next toss (assuming it's not loaded or a 2 headed coin ie cheating). In the long run (long as in 1 year of mining) the rewards so approach close to 100% of expected, but that's not to say bad or good luck won't continue. Having said that I'm still taking offers to move away from certain pools as I can offer stats showing I am the most cursed miner |

My suspicion is that some shares were lost or not counted. The difficulty change has not yet occurred but I'm down over 0.11 BTC today - roughly the 3 hours missing on the miner graph. Either the website balance is not correct or I lost 3 hours of work on 19GH/s. And I'm on PPS, so it's pretty easy to calculate loss (as no pool switching has occurred in CGMiner).
Could the balance being reported be lagging behind? Or is that the true current balance?

As somebody who swore off ATI cards (ATI AIW original Radeon was so crappy with horrible drivers) until starting mining in 2011 I will tell you the only effort worth putting into nVidia cards is to sell them and buy an AMD card. Even a $50 used AMD 5770 will mine faster than GTX690.
If you're not willing to put AMD cards in your system you're better off not mining. It would be like trying to eat soup with a fork - you can do it but why.

nah - make it pps and we'll talk
The only way any new pool will do PPS is if they charge a 10% fee. Anything lower would pretty much be charity or a scam without having a 2000BTC buffer. ARS, MTRed and OzCoin remind you of anything? |

I went on to butterflylabs and told everyone about batch 2..
Oh, this was their response..
Looks like schadenfreude to me. No wonder they got pissy. * abracadabra mumbles something incoherent about OoC and his big fancy words  They're big Aussie words (although that one looks Germanic). |

Pansies. Some of my multicard rigs idle at 57C on the hot card, so keeping under 90C is good....considering the ambient in the room was 103F. That was with full AC running in a commercial building - outside ambient was 106F last week here in SoCal. These damn voltage locked cards will the first to go  |

I had one during my college days - was a beast to transport but it could easily support me sitting or standing on it (and I was 230 all muscle back then).
I read that, looked at your avatar picture, and got a little shudder. Lol, that gave me a good laugh. I use that pic since it looks a lot like my wife and my little girl kept calling her mommy when my wife was on vacation. Maggie Q for those interested. If I found out about BTC in 2008 before I got married I would easily have over 10k coins with all the old hardware I had laying around. Arrived late to the party relatively speaking because of wife and kids but wouldn't trade them for less than 20,999,999 coins (I'd let Satoshi keep one (and yes I know BTC white paper wasn't until 2009 and a whole pantload are lost). |

 Find something like this on CL. Plenty of room to put cards. I know that case - it's an Inwin Q500 I had one during my college days - was a beast to transport but it could easily support me sitting or standing on it (and I was 230 all muscle back then). |

Its going to take a while to reach $200+ prices again since everytime there is price increase all the people who bought before the bubble at inflated prices try to recoup their losses by selling.
Despite all the news coverage bitcoin has gotten lately, the word hasn't gotten out that there is an ridiculously easy way to send money over the net. Once the masses pick up on this everyone is going to follow each other like lemmings and prices could easily reach $500-$1000.
There are only 2 obstacles to this. First there is no easy way to buy bitcoins online. Second there is not yet many popular online market places that use bitcoins other than SR. If people can buy all their online needs with bitcoins they will prefer to do so.
I concur. Every lame media piece on the news focused on the frenzy and crash - some even neglected to state that BTC can be used by a regular person to send money. They focused on lack of government oversight and anonymity and drugs. Once people start to realize that this is a viable option then it will go past 300. But they won't realize it as viable if the price swings 20% every day. Catch 22 I suppose. |

Has rates won't vary on your end (other than +/- 2-3 MH/s)
Your submitted shares per minute will vary. In CGMiner that's the "U" that's in the top right. About 1 share per minute for every 71 MH/s, so a 600MH/s miner would average about 8.5 shares/minute.
That's the expected average. Sometimes you'll submit 2 shares per minute, sometimes you'll submit 15. That's why what the pool shows your hashrate to be will vary - it has to guess based on your submitted share count. This won't show much variance after about an hour.
Does that answer your question?

I sold my eldest child. She can only vacuum and do dishes at a slow rate. I figure my Batch 3 Avalon is a better investment and will have a much better ROI than any kid.
Still considering selling my kid #2 and kid #3.
Bowjob - consider taking a loan from one of the forum members. I'm sure some members would be happy to make a deal where they take repayment in BTC (which you should be getting shortly from your Batch 2 Avalon)

Maybe I just haven't heard of it but is Lepa a decent brand? I only see 1 review on Newegg, and 1 review on Amazon of this PSU. Even though its 80 plus gold rated, running it near 100% capacity especially 24/7 isnt probably going to last long. http://en.wikipedia.org/wiki/80_PlusAlso look at what 80 plus gold actually means. At 100% load its only putting out 87% at best. So 870W. So even if your cards were only putting out 200W then your still too much power. You're failing to understand how PSUs and their power/efficiency ratings work. Some Gold rated PSUs like Seasonic made ones are well over 90% efficient at full load. If PSU is only 87% efficient, it means it will draw 1.0/0.87 * 1000W (in this case) if it was maxed out (assuming it can run the full 1000w - cheap PSUs can't). 87% efficiency doesn't mean it can only put out 87% of maximum power. Lepa is a decent brand (part of Enermax's budget line). |

I think i know what's wrong, it is the score of individual miners not resetted to zero after a new block is found...
One of my miners has 6 digit figure score while another miner with same hash rate has score of less than 100
It's not after a new block is found. At certain intervals the pool resets all miners back to 0 as baseline. If you mine for the first 4 hours on a 5 hour block you will make essentially 0 since there will be a reset sometime between when you quit mining and the when the block is found on the 5th hour in this example. I too noticed some of my scores were a 6 magnitudes higher than other miners with the exact same setup. 2 1250MH/s rigs, one had a score of about 4k, the other was in the millions or billions. Whoever gets lucky enough to get those messed up scores gets paid extra and everybody else is having their rewards "stolen". So in essence the pool is making you play a lottery. If somebody could figure out how to trick the pool into keeping the score up then they could basically steal the 25 reward of the block. So whoever chooses to stay here after seeing this consistently is asking to be a victim. I PMed Slush after the first occurrence 3 nights ago, no reply. He is a standup guy. His pool right now is behaving otherwise.... |

Ok. Fuck this. Time to find a new pool until we get an answer on what is going on.
Exacty. 3rd time in last 3 days this has happened. I can't see any reason to stay here any longer. 3 hours of mining to get the equivalent of $0.30. Normally i get about 0.05, but 0.0026 come on. It's not like I'm a slow miner (20GH/s x 2 and both got screwed). 17995 2013-05-12 05:35:52 3:07:09 25945750 49070 0.00266237 none 235787 25.49480000 92 confirmations left Leaving until the next DDoS... |

If I mined with 5GH/s at my house in the Socialist Republic of Kalifornia, SCE would run me $720/month before AC costs. Considering it was 90F today and will be 95F tomorrow, it would probably be $1k with AC running  $170 is damn cheaper than most everything (except free) |

Nevermind. Looks like it took forever to update the payment for that last block.

Having said that you're a fool if you're trying to run 5970, 6990 or 7970s in a 4+ configuration off a board without additional power.
Wrong. In fact, both of the dual GPU cards you mentioned draw *less* current through the PCI-E slot than their single GPU counterparts. The 7970s don't draw much from the PCI-E connector either. I don't want to get into a shouting contest but I think it suffices to say YMMV. If I have my 4x6870 rig running in 40F ambient I pull almost a whole 80w less from the wall than I do if I am running in an ambient of 95F. After 2 years of mining I'm starting to see some extenders go bad as the temps are really heating up here in SoCal. So a blanket statement of you DO/DON'T need powered extenders is silly. Some people are able to run their cards in a milk crate like TacoTime. I tried that setup and most of the cards went to thermal throttle withing 3 minutes. If you are running overclocks (and I don't know too many people not running OC) with powerful cards you could benefit from powered risers. Are they necessary - well than depends on each individual application. The thread title says they are largely unnecessary. I don't use powered risers because I can't have a density of more than 600-700w on a rig without heat problems. People who can pull 1100 watts off a PSU probably should consider using one - IMHO. |
