I'd recommend poclbm instead of Phoenix. Phoenix has simply fallen too far behind to be a good choice anymore. poclbm has the latest optimized phatk kernel, plus support for X-Roll-Ntime so it will never be idle just because of network delays. I have a branch of poclbm on Gitorious that will also resend shares when there's a network issue (sometimes this causes invalid/duplicate for the retry, but you can ignore those).
Luke-jr, where's your branch on Gitorius? I'd like to try it out. Thanks. |

Can you make another version that includes all the recent changes and __init__.py does not need to changed?
thanks
Why? Just unzip in the kernels/phatk/ directory. Main reason is some people like to use this kernel with poclbm. The 7-11 works, but the newest doesn't because it requires changes in __init__.py which is specific to phoenix. BOARBEAR is asking for a version that includes all the additional improvements since 7-11 that doesn't require any changes to __init__.py. |

He's using floats to try to be perfectly fair and everyone gets their exact share. It gets rounded when you withdraw and not just rounded down when you earn your share.
It's probably not worth it to be that precise since 1 satoshi is not worth much. But why are you so against it that you would quit mining here? Is using floats going to cheat you of something?

Yeah, it's a known problem. I think it currently just checks every 5 minutes. If a block is found, it just assumes the latest found block is it. I think that's a bug with SimpleCoin, but not sure. I assume BurningToad is planning to fix it.

Here's what my pool says: ChocoboLee.21 Y 1482 Have other people had success with running cgminer with 6 gpus? Is it possible that it's not able to handle all 6 efficiently? This is happening on both my machines. Should I try other things like setting number of threads per GPU? |

Can't get or set fan speed for dual gpus like 5970.

-------------------------------------------------------------------------------- Funny thing is my pool is seeing a higher hashrate: ChocoboLee.11 Y 2126 From poclbm, I was getting 374 mhash/s or a total of 2244 mhash/s. So something really needs to be fixed with the hashrate display for me to use this miner. I will try intensity 8 when I get a chance. |

The guy who has the address that start's with the number "1" is really lucky xD You just have to remember the first digit.
lol, that's probably Satoshi. |

GPU 1: [361.9 Mh/s] [Q:1619 A:1426 R:5 HW:0 E:88% U:4.91/m] setting intensity to higher values gives me more hashes/second but less shares/minute Hmm, ok. I guess I was fooled by the hashrate. ckolivas, can you also display an effective hashrate number that is based on shares per minute? That way, people can easily see that something is wrong if the effective hashrate does not match up with the theoretical hashrate. Thanks. |

I was getting 760 shares in 35 minutes with cgminer. With my previous poclbm, I got 960 shares in 35 minutes. So I'm definitely returning less shares with cgminer at I 14. I will change it to I 8/9 and test it. But I won't have time to do that for until maybe 8 hours later. I will report back what I find out.
Is it possible that I'm doing that many hashes but not reporting back to the pool all the hashes I found? Are some hashes lost when intensity is set so high? It would be nice if that information is captured somewhere.
|

|

Because your efficiency is low. The pool reports back what it thinks your hash rate is based on the number of accepted shares you return.
Efficiency is just accepted share divided by requested work. A low efficiency just means that cgminer is calling more getworks than necessary. The hashrate should represent how many accepted share I generate. So the question still stands: why is cgminer reporting a higher hashrate? How is it calculating the hashrate if not using the accepted shares? Another question is what does the intensity actually mean? I'm running on a headless dedicated miner. Why not set it to 14? And why not 9 instead of 8? Thanks! |
|
|
|
Your efficiency is particularly low. That may be the result of setting the intensity too high. Drop it from 14 to 8.
I've tried 8 and I was not getting good hashrate. Would 9 work? Why would the hashrate reported here not be accurate versus what the pool sees? |

I have a weird problem. cgminer is reporting a hashrate that is a bit better than what I had before. BUT my pool (arsbitcoin) is reporting something much lower after I switched. And I did wait 30 minutes to make sure since the stats are for the last 10 minutes. Here's what cgminer is showing: cgminer version 1.2.7 - Started: [2011-07-17 04:12:34]

Donation sent! When you release the next version, please explain whats changed in __init__.py. I'm using fpgaminer's poclbm w/ phatk: http://forum.bitcoin.org/index.php?topic=19169.0I'd like to see if we can make your phatk kernel still work with that. Thanks! |

All 6 for $1740 ($290 each) or 127 btc. |

I don't know many people that mine with an iMac. And I have heard people burning out their cards. Don't know how hot their cards are though. I have an iMac with a 5750. I was getting 77 mhash/s. Once I heard the story of someone's iMac dying, I stopped mining on mine. Not worth it... so I just got a dedicated miner.
