Hey, this one is quite disturbing since the relative rig used to mine without stop for almost 5 months..
This is a 2 x HD5970 setup
OS: Windows Professional 7 x86
Driver: 11.12 ATI driver
SDK: 2.5 (tried 2.1 as well)
Latest CGminer 2.10.4 with stratum
Tried with older CGminer versions as well but i always get the message "Display driver stopped responding and has recovered" and afterwards all 4 cards appear with a ridiculously low hash rate.. tried different pci slots ..tried cgminer without any options.. nothing
Any ideas? Thanks
Did you post this problem in the CGminer thread? |

Your mainboard is toast, congrats.
When i remove one specific 5970 there is no issue, so probably board is fine This is a dedicated rig and i do not get any hardware errors Well I can only tell you what happend to me it was the board here. I think the error comes from some pcie issue. I've seen this error when kicking off firefox while mining. Or when doing a remote desktop session into the system while mining. |

"Display driver stopped responding and has recovered"
Any ideas? Thanks
Are you using the system for other things while mining? Or is this a standalone rig? Do you get hardware error's? |

Hi, i switched to POT too, i always like a bit of gambling. I'm just confused, or just plain stupid, with what to set at vardiff and how that translates to the overall performance of the miner. My hash power is around 450Mh/s too, so what should i set vardiff too? Currently i have it on 15. Is this just plain stupidity, ignorance or is it ok??
And if someone could explain in a simple way, how the value of vardiff affects your shares? I'm don't know how to read the stats in ozcoin. shares, vardiff shares, avg share diff 1 and so on...
Sorry for the noob questions, but i do like to learn, if someone has the will to teach!!
Thanks.
Well, with your diff set to 15 you will submit approximately 15 times fewer shares but they will be worth 15 times more so it should even out. You don't really need to change your difficulty from diff1 until you get in the neighborhood 2 to 2.5 Ghs. Now, I'm not sure how that would relate to POT since you want to submit higher diff shares anyway, but I would think it would hurt you with the low hash rate in the long run. You should do some trial and error changes in 24hour increments. Sam Edit: Thought about my reply a bit. I don't think you would loose any revenue in the long run. Your just using less bandwidth which is probably low anyway at your hash rate. But I still would do some tinkering for use with POT payout system. |

a home built electricity generator, we'll see if anything can come of that,
Not sure what you have in mind for "a home built generator"? But you could pay for allot of conventional electricity with the money solar or wind generation would cost. It would take a VERY long time to get a return on that investment. Not that I think it would be a bad idea mind you, just expensive. Sam lol I'm not going to pay for that kind of overpriced stuff I want to build it myself for the hell of it and we'll see what happens  hopefully I won't disintegrate myself or blow up the house by accident O_O so I guess some rubber gloves etc. might need to be ordered, since I only need to power a fan really it'd be interesting to see what would happen. I actually think if I get the heat down using a normal fan that's not powered by expensive coal then that would cut the costs dramatically and I wouldn't have to feel so worried keeping it on overnight. There's only one problem with this idea or several depending on how you look at it, I have so many practical issues to consider depending on what sort of climate I'm in and hydro-electric seems like the most sensible option to pick because when it runs it can run constantly, I don't have a running stream nearby though so of course I'm going to probably end up having to invent a way to artificially generate the electricity. I also need to look at how to build the generator itself properly, you don't need overpriced and industrial wind turbines etc. to power a fan, they don't take that much electricity but I'm going to have to take some time to properly think about this so I don't blow myself up or anything daft like that if I accidentally discover something lol. Well I guess you can train the Guinea Pigs to row a boat like on that Geico commercial. |

Dead? Maybe, but it hasn't stopped moving yet! 11 of the pools on Corti's list offer merged mining. And there are two requests to note this feature in the OP.
I have a couple other questions/thoughts about NMC/MM. Is there a more appropriate thread, already started, to post those? Thanks for the thoughts. Sam |

Even if it was 0.01%, I'd still prefer to support the oldest (and only Satoshi endorsed) altcoin.
Why? By most accounts that I have heard it is a dead project. Initially I thought NMC's were going to be used for something cool like to "buy" DNS entries but then found that they are just a useless by product. So I just don't understand the craze. Seems to me it wasn't thought out very well. I do agree that a distributed DNS system would be good and even necessary in the near future. Sam |

I'd be here if namecoin was on stratum.

That is a good point. I've switched back to getwork on ozco.in as nmc is definitely a larger part of equation now. Graet, would you reconsider adding nmc to stratum? Merged Mining has caused enough grief / pool instability. This is as good a time as any to jettison this bad idea. |

Thanks guys and Graet. I tried Bitcare and Minerstatus and both refuse to work. Minerstatus say that it gets no response from the server. Hmmmm?
could be due to the API updates, I will email David - he usually updates with next release cheers Both Minerstatus and Bitcare haven't been updated on Google Play since September. What is a good iPhone/Pad app for Ozcoin? Anyone have a suggestion or experience with one? Thanks, Sam Edit: rephrased a bit. |

Hello everyone, I'm new to Ozcoin but a longtime miner.

Where is your pool one getting GBT Longpoll from ?
It's right there in the screen scrape, its that "redacted" pool. |
|
|

I got it, up to 10 connections now and slowly climbing.
The short of it...
Install bitcoinqt client and sync with block chain
Be sure the computer running the bitcoin client gets a static IP address assigned by your router
Forward port TCP port 8333 from internet to the IP you assigned in the step above
Done ;-)
-Wave
Why does it have to be TCP port 8333? Why not? It has to be something. I guess that is what the programmers decided on when they started the Bitcoin Client development. |

Maybe we can propose a change to the fee rules that put less fees on transactions that reduce the number of unspent tx.
Transaction fees are a very important part of Bitcoin, so I would NOT advocate mucking with it. I don't know what you mean by "unspent tx". Whats your definition of an unspent transaction? Sam Edit: forgot one little word |

OK, I'll try to restate again I mine 500Mhs/s on p2pool and get a bunch of small payments per block and get 13 BTC and pre order a Jalapeno. I mine another 13 BTC, say on Deepbit, with a 1 BTC threshold to a different wallet and pre order another Jalapeno. Will the 13 BTC from p2pool require higher transaction fee to spend because they comprise a bunch of small input transactions? Thanks, Sam With 500MHs/s your average reward should be around 0.04BTC per block found. You can pack several inputs in a transaction with a 0.0005 BTC fee so your loss from fees is less than 1% when you use p2pool mined coins. So if the alternative is a pool with more than 1% fees you're automatically better off with p2pool. Currently the fees earned by block mining are around 1-2%, so if the alternatives don't pay you network fees, that's more you lose vs p2pool. And lastly, my 2 months performance on p2pool is 107,5% vs expected 100%PPS so p2pool seems to have a higher than average reward than most pools. I didn't even count some small downtimes in that period so it's a low estimate. This matches what http://p2pool.info/ reports: constant higher luck. One explanation may be that p2pool is by its nature better connected to the bitcoin network than most pools: all P2Pool nodes quickly broadcast a p2pool found block on the bitcoin network which may lower orphan rate. That's a very helpful explanation. So at 4 Bit Cents per block my 13 BTC example would have 325 inputs. Would that really be only a 0.0005 BTC fee? Does anyone have a real world example? Thanks, Sam |

That's all well and good, but it doesn't answer my statement/question. I'll attempt to restate.
Spending your coins mined "in increments" on p2pool will have a higher transaction fee associated with it than coins received, say, 1 Bitcoin at a time.
Is that statement correct? Or not?
Thanks,
Sam
I'm not sure what you're asking. If you're saying "if I spend 0.25 BTC at a time, instead of waiting until I have 1 BTC to spend, and I pay 'proper' transaction fees for each 0.25 BTC", then yes, you'll spend more in transaction fees. AFAIK, there aren't fees associated with mining. M OK, I'll try to restate again I mine 500Mhs/s on p2pool and get a bunch of small payments per block and get 13 BTC and pre order a Jalapeno.

I doubt that you really want an answer to that question.
Actually I do want an answer. Cool!
But one possibility is maybe because you get paid allot of small amounts instead of meeting a threshold and getting paid a larger amount in one lump sum.
When you then spend your coins you could end up paying a large transaction fee, correct?
Sam
Yes, incoming mining payments are in increments. --snip-- No transaction fees for receiving it, and you can spend it when you want, with whatever transaction fees you'd pay normally.

Yes, but it's a " so you're telling me there's a chance" can. With a=0.4 and wd=1, the chance that a share will cause a loss of more than a reward of a single block is about 1 in a quintillion, I think they can handle it. Ok, if that's really the case then I withdraw my objection. The probability of Ozcoin being wiped out at a=0.4 is many orders of magnitude lower than the probability of a meteor destroying all life on Earth :-) roy Hmm, should I feel better now? Just two more days to the end of the Aztec calendar you know . Sam |

There are alot of ppl that only mine and have no clue about compiling or setting up git or mingw on windows.
I wrote windows-build.txt so anyone could compile a cgminer binary for Windows. It only takes 30 minutes or less to set up a build environment following the instructions provided. So I read that as "There are a lot lazy people that only mine and have not bothered to read the included documentation".  I`m sure they are Murphy`s law about documentation: "NO ONE READS IT" "NO ONE READS IT", first. |
