I know what you mean I went over to multipool which I used to use for scrypt mining on gpu's as they were trying to get their Bitcoin pool hashrate up. I spent nearly 48 hours there without getting one decimal fraction of a BTC because basically I was like 15% of the hashrate on my own. Effectively it was like solo mining.
Whats P2pool like as an experience?
It works pretty well if you have enough hashpower, but the variance is very high if you are a low-hashrate miner. Some hardware (like Knc H/W) does not work well with it, at least it didn't the last time I tried. The payout is good - miners get 100% of block reward + transactions. But a 2% pool fee? According to p2pool.org P2pool.org is not the same as P2pool - you are mining on a node owned and operated by someone else, and paying them a fee. P2pool is meant to have each miner create his own node for mining. The P2pool software, by default, will automatically give 1% to the author, but you can set it to 0% if you choose. Aha! Sneaky bugger. Looks like http://p2pool.in/ is the official site. Looking into it now. Looks like lots of info here: https://bitcointalk.org/index.php?topic=18313.0Also looks like a royal PITA to setup especially for noobs. |

Honestly, I think that if anyone is really deeply committed to 'doing your part' to fight decentralization of mining, you NEED to be mining with P2pool, or using your coding skills to help forrestv make it the best pool option available.
P2pool (or some other yet-to-be-invented distributed pool system) is the ONLY chance to really fight decentralization. Expecting miners to altruistically choose their mining pool is NOT a realistic long-term strategy.
I tried to use P2pool, but right now, it simply does not work well enough with the fastest ASIC H/W currently available - or maybe the H/W does not work well with P2pool. Regardless of where the fault lies, miners are going to use the fastest H/W they can get, and P2pool will lose until either it adapts to the H/W, or future vendors adapt to P2pool.
In any case, the point here is that distributed pool mining needs to be the future if decentralization is to be avoided. Anything else is just a losing strategy. Altruism, while admirable, will not save the day here. It will just lose you money in the short term.

does anyone experience some variances after 0.99 upgrade? one of my Jupiters were hashing at about 450gh/s then suddenly after 20 days of mining suddenly drops on 430gh/s after 0.99 upgrade i get only 380gh/s. i assume one of the boards, because it gets hotter than others.
anyone have similar problem?
try wiggle the pci power connections.... use bertmod to watch the vrm come to life... had the same happen... could help. **On Eliguis... I'm really happy there... We solve blocks like "White on rice" compared to slush, the transaction fees really add up... and Wizkid has proven to be VERY reliable... and talented. High % uptime; and the graphs aren't done...he's working on them.... right now actually; along with many other features... given time, I'd bet he's planning merge mining other crypto's like LTC, DEV, like ghash.io does..... No offense to slushie pool, he's a talent himself! These guys are brainiacs.... just I like Eligius better for a few reasons, NMC, no pool Fees, shared transaction fees, etc... the graphing... I think Luke & Wizkid should join forces.... just a thought.... I thought Elgius was known as "Luke-Jr's pool" but wizkid057 maintained it? |

Maybe that's real, and maybe it's just FUD to weaken a strong competitor - I don't know and frankly, neither do you at the moment. I'll give them the benefit of the doubt for now. Innocent until proven guilty and all that, you know. Whoah kano went off on one there at the end  |

Well a non-existant January delivery Hashfast Sierra just sold for $8500 on ebay, thats $2200 more than they actually cost on the web site.

Heh, and just below it is the email that KnC sent them - dated the 15th last week. So no news there. |

who are you? does this mean they will deliver product or are you some one trying to distract and stall for time on behalf of hash fast
What do you mean by "stall for time"? Do you know something that we dont know and Hashfast need distractions? I do hope they will deliver a product... Maybe ease up the orders on knc, so we dont have to wait so long for one. The original post said that we will be getting some info and releasing as soon as we get it... Then I said, they promised it to us yesterday.... Then I said that as soon as it comes in a will let you all know... Then I posted a pic.... So you created a new thread to announce the news that Hashfast were going to tell you some news, maybe, yesterday? You know there are like half a dozen Hashfast threads, even official ones started by them in the "Custom" sub section of this forum, you could have posted your "news" in there for all the hundreds of people waiting for official news from HF on their delayed hardware. Just seems wierd you would start one here.. you must admit it looks strange. |

Who let you out of noobie jail? At least you can't delete people's responses now you're in this thread. I doubt you are going to get much sympathy in here throwing around your vague complaints and posting what is really just slander. Don't feed the trolls lemonte, and don't quote them  |

Been out of the forums for a few months, busy with other business. HashFast -> Don't really know much about this one. Cointerra -> Went bust, right? KnC -> They are shipping but big QA issues right, but still in the end delivering more than promised? They come and go out of stock constantly? They are in sweden - anyone know if they allow payment during pickup? For me it's quite quick to get to Sweden since i live in Finland Did their original announced timeline hold? So many entrants on this very expensive field to get started up - somehow i think many of these are outright scams. I'm looking to offset risk by putting in orders for multiple places. No one seems to have anything in hand - except a few very expensive options @ eBay? +Bitfury as well Its pretty tricky true, you sorta just missed out on the Bitfury 400Gh/s rigs and the KnC 550 Gh/s (Oct) and 650Gh/s (Nov) rigs which are really the only ones that have sold production runs in any significant numbers. I wouldn't say that KnC have big QA issues, I think there are a small number of people with minor issues which are fixable by RMA'ing, and a tiny number of people with catastrophic issues, but compared to the number of miners they shipped its probably something like 1-2%. I think they had some teething problems in the rush to get miners out to customers as fast as possible, but all in all they have done a good job, from my perspective anyway. Things they could improve are really limited to customer services bandwidth, I think they have been swamped with requests for info and the usual customer issues regarding accounts and payment and shipping and delivery etc etc etc etc. They are still a small company really and i think once the Nov batch is out the door its going to slow down till next year and they can consolidate. I have a KnC machine. And yes they sold on 100Gh/s per ASIC board and delivered around 170Gh/s per ASIC board. Bitfury seem to come and go in and out of stock, although they are out at the moment, I don't have one of their rigs, for me the way the boards and everything go together is more at the enthusiast level and from reading the forum the rigs can be somewhat tempermental, probably no more than any other setup. Not sure what their plans are for future batches, but certainly one to watch out for. Their boards also seem to be able to be voltage adjusted to provide up to 25% more performance. Hashfast and Cointerra, seem to be in a similar boat, although proponents of each company will disagree, but looking from the outside they both seem to have missed some of their deadlines for the pre-launch phases of production. I don't know how much that will affect their delivery times, but any lack of communication on their part seems to not give a good impression as to their ability to deliver. I hope they do, for the sake of all the people who sank money into them. Can't comment on the others, I just browse them looking for news and price info, some are starting to surface with quite high price levels, I'd like to stay around the <$5 per Gh/s moving forward through the next 3 months if I was buying. |

It's a skewed perspective. I just measured the distance and there is 17cm between the miners and the wall.
Well, if you think 3/4" is enough.... 17cm = 6.7 inches You are thinking mm |

biffa.. they're say they're not behind schedule... their dec orders will deliver in late dec and their jan, feb and march orders will deliver in those months. there are some other groups who are running late, but as of right now, cointerra isn't one of them. we will see if they can keep it up... you may have confused cointerra with blackarrow... the link you provided goes to blackarrow No I meant cointerra, pasted the wrong link apologies. As for Cointerra, Hashfast, blackarrow or whoever, no-one except bitfury and KnC have delivered 400+Gh/s miners at all yet, I hope someone else does soon, I just worry about the lack of information coming out of the latest companies offering hardware. There is no import duty for computers or computer parts into the UK, you may however pay a handling fee to whoever sends it. Also if you go and pick it up you still may have to pay VAT when you try and get it through customs. |

I've seen motherboards completely submerged in mineral oil. It doesn't conduct. Or course water doesn't conduct either unless there are impurities. If it would spill it would find impurities pretty darn quick. Not sure if mineral oil with impurities would conduct as easily. As far as burning out the pump, probably not the pump but the motor might see more work - I'd say the cooefficient of friction of mineral oil is quite a bit less than that of pure water.
Sorry I edited my post from earlier to explain a bit more. Yes for immersion its fine, but pure water would be better, but it will become conductive too fast even pure distilled water. Plus you need a lot of oil volume to make it work. But a loop is too restrictive, and there wouldn't be enough oil to conduct the heat away fast enough. Hope that makes more sense. Many people have seen the oil immersion demos and thought the same thing you have over the years. Unfortunately the science doesn't fly in a regular w/c loop sort of configuration. |

Some geek pr0n with a kink thrown in for added distraction As you can see there is still tweaking to be done. So I got that goin for me Very nice. Is it water or mineral oil circulating? Water, you wouldn't you use something less likely to conduct the heat? Mineral oil has 5 times less thermal conductivity than water. Plus it would burn out your pump fast pushing it around a restrictive loop. The only reason they use mineral oil in full immersion type cooling is because its non conductive, but you need lots of it. To the OP nice! I couldn't stand the downtime and wated BTC to even try Plus I think the hottest parts of our rigs and the parts most affected by heat are not the cores, but the VRMs. However I like the upside down board and the nasty kink just before the rad |

You mised: mv /usr/bin/cgminer /usr/bin/cgminer_old You should always just stop the normal miner and run ckolvas's new one from the root directory to test it before you copy it over the one in /usr/bin The only way back now is to reflash 0.99 unless you made a backup as above Should be back to normal after that. |

|

 What happened with 3.8.2 on FW 0.99 Are you running it from root or did you copy it over to the /usr/bin directory? |
|
|

Guys this man deserves our tips! ckolivas: The file has a different date but the version is the same? |
