hi again, I'll worry about my 'lecy being cut off later I guess so am happy to accept your offer of GBP equivalent to €1,100 including shipping to Spain, if you'd like a free holiday then feel free to bring it over yourself - though we've also got the EU Siberian winds cold snap atm, can you just remove your private data & leave all the rest pointed at an easy to start with miner or set one up for me, I don't mind if you know my passwords ID etc for that, let me know how best we can escrow this - if you can trust me I'm happy to Internet bank the £s on delivery or BTC as you like, my eBay ID is over 10 years of 100% very positive feedback with well more than 1,000 transactions if that helps looking forward to giving your fab miner a new home in the sun, feel free to visit it any time you like  Let me know if you are still interested in the support. I can do it and get you up and running at 447 mhash/s easy-peasy in 30 minutes I think with latest software and completely stable ( depends on CYPER's cards and their quality but I think that won't be a problem ). I understand CYPER and if I were him I too would format the HDD and remove all personal info with Guttenberg erasing technique  . You just need to be able to install the Linux initially then I can take over and do all of the software after I get SSH access if you want. Thanks ! |

I can send you 100G plus if you pay in advance at 120% PPS (no bonus needed). Will need at least a 4 day contract so 350BTC.
You must keep your pool online however, you will have to pay for dead time:(
PM me back if you really want to solve that block.
No thanks Goat. Yeah. IMHO that would be "cheating" your users Goat. You pay them 115 and you get 120 so 5% profit for you. But this is not any work you do at all. It is a public "buy low - sell high" so IMHO users can mine directly with a1bitcoinpool rather than give you that 5% for nothing If you do "backstage" non-public deals that actually require work then IMHO that is totally OK with me and none of my business but getting 5% off them publicly like this is LOL. This is not an attack on Goat. I actually like his morals and his transparency and charity stuff but this is  . I spotted it as well but I wouldn't think anyone would jump. Guess I was wrong  Anyway, I don't think this will last once we solve that first block but hope I am wrong  |

please add to phoenix overclocking support...
please no. don't turn phoenix into the monstrosity of some other miners. it's simplicity is it's beauty. do one thing, and do it well. when you throw everything possible into one program, you end up with too many compromises. I 100% agree and support this decision. Remember the KISS principle. If you need OC stick to AMD API thing. |

Damn if I can get this working, I think I can safely say I have the largest e-peen of all the GPU miners here. If I want to sell it to an enterprise or government, I'd probably have to load it with "Pro" cards like FireGL shit and Quadros though. I think there are a few FireGL cards that have 1600 shaders each and only take up one slot.BTW, I know of Quadro-based systems that have more than 8 GPUs - wonder if the "pro" drivers remove that limitation, or whether nVidia just has never had such a limitation. What cards have 1600 shaders and only one slot except watercooled 5870s ? AFAIK Nvidia has no limitations on the number of GPUs but I think they may have an artificial one like ATI with 8 ( maybe 16 with Nvidia ? ). Ask the folding guys. |

what kind of price are we talkin for a rig like that? that would be insane.. Well, I'm going to try hooking up used server power supplies, to keep cost down there. I have found some 2360 watt PSUs for less than 100 bucks, and they are 91% efficient at full load! The board costs close to $1200 new, but I got mine for $600. The largest cost will be the Single Board Computer that runs the whole show - this board is only a backplane. New, the SBC (AKA System Host Board or SHB) is between $1500 and $3000. I hope to get some used ones, but I don't yet know the cost. I am going to be experimenting with VT-d and AMD drivers to see what happens in a virtualized environment. It is going to be a fun experiment, and hopefully I will come out of it with the fastest single system ever built. It probably won't be -the- lowest power usage system, since the SHB has 2 quad core Xeons, but it might rank pretty high, if I can underclock them. (Or remove one and have a single quad core) Even if it is far more expansive than it should be, I might be able to sell the complete system for uses other than Bitcoin mining, since systems of this sort are usually $40,000 and up. Especially with more than 4 video cards. Loving people like you ( with server PSUs and server backplanes ) and people like P4Man ( oil submerged rig ) that bring new creativity and ideas into the community and actually carry out those ideas at great risk to themselves and share with us ! Thank you ! |

It seems that this does not report VRM temps on a reference 5870 at all.
The values are too close to core temp when VRMs clearly run at 90 degrees or so.
How can I modify the code so that it reports correctly ?
I already modified 1002:6899 to 1002:6898 so that it works with my 5870 and not only 5850s.
Too sad that development is dead because this really could have been heaven for Linux miners like myself !

I have the GPUs at 70o and adjust the fan automatically with a control script
Max acceptable fan speed for me is about 70%; more than that level it is very noisy and I can't stand it. Besides, I also afraid that high speed could kill the fans quickly
Ambient temp is around 25oC at night to 33oC noon.
Yeah exactly what I am doing as well but I was wondering if it would be better to raise the fan speed so as to bring down the temps to 60 degrees constant instead of 70 ATM. I wonder what the VRMs are doing at that temp ! In Linux using radeonvolt I don't think I am getting the VRM temps because they are too similar compared to the core temps so I think it is getting something else. |

So after 9 months on mining with 30 GPU (15x 15970s) I have two "degraded" GPUs. GPU #0 on .183 rig and GPU #5 on the .184 rig (which will crash about once a day - hard hang even on stock w/ low temps). I also have "lost" 2 fans. Be interesting to see what my "attrition" will be at the one year mark.
Good to see that these cards are somewhat resistant to mining long term ! We need more analysis like this done. I just started mining so hopefully I won't have anything to report for a looooong while. LOL ! |

and whats with the driver limit?
You can run a maximum of 8 GPUs using the ATI driver on Linux or Windows ( recent drivers like 11.6 etc. ) You can have like 4*5830 and 2*5870 and 2*5850 on one of those boards. |

Will this include automatic fan and gpu management like cgminer ?
What about killing mining thread on GPU that has a dead fan while I am away ?
IMHO cgminer is good because of auto fan feature and support for backup pools and screw all that python BS.
Thank you !

I am referring to longevity.
Is it OK if they are at about 70 degrees Celsius 24/7 or should I increase the fan speed to keep them at 60 degrees or lower ( fan is less expensive if it dies compared to GPU core electromigrating ).
At what temperatures would you consider running your cards 24/7 as a dedicated miner ?
What temperature is needed to avoid electromigration ?
Thank you !

IMHO all of these strange cgminer issues are on Windblows only / mostly. I would avoid that platform if I were mining.
You are gamers so that is why you won't consider Linux. Try dual booting and cgminer works flawlessfly for me on Linux.
I think it should be like Xchat program : free for Linux and if you need support on Windows you have to pay.
Windows is just too much hassle for mining. Good luck !

Not sure why it matters,
7x 5970 would be the the max for an ATX motherboard
Around 5ghs I suppose.
Yeah sounds like you managed to hack the limit that ATI imposed on Linux of 8 GPUs for a system ... It is either 4 * 5970 or 4 * 7990 OR 8 * 5870 or 8 * 7970 to get maximum hashrate per rig but trust me that 8 * 5870 setup is impossible to do unless you live in Antartica with decent temps. Wouldn't extenders make this easy? If you ignore the fact that some machines have BIOS limitations on IRQ ranges and that kind of stuff and also that it really is hard to get Linux to run all 8 cards then good luck. Been trying to do a 8 * 5870 setup since June last year. Finally gave up and split into two 4 * 5870 rigs now. I'm no noob but unless you put them in a fridge or something the heat output in that small a space is very hard to cool down. Well I am a noob but the small amount of time I've been doing this I do know that spacing seems to make all the difference in heat buildup. Now software issues are a different thing... You would also need powered extenders because trying to draw 75 * 8 = 600W through the mobo = recipe for disaster. You also need a MSI BB Marshall P67 B3 motherboard ( only mobo that has 8 PCIe slots ). I got 2 for sale if you wanna attempt this. I'm in the UK etc. |

POCLBM is broken and will fail at every pool. Do not use this by itself or with GUI miner. Inaba noticed this issue at eclipsemc and I think it is part of our problem as well. Please change to CG miner if you can. I have had issues with Diablo miner with the 7970s  So Diablo is broken as well !? I thought it was only poclbm problem. Thanks for telling us ! |

Yeah. Probably has to do with adding it as the first listed sticky in this pools thread |

Whatever drivers and SDK linuxcoin comes with; SDK appears to be 2.4, Im not sure how to check the driver version. I do see this in the log:
[ 38.627] (II) ATI Proprietary Linux Driver Version Identifier:8.86.5
[ 38.627] (II) ATI Proprietary Linux Driver Release Identifier: 8.861 $
[ 38.628] (II) ATI Proprietary Linux Driver Build Date: May 24 2011 22:46:53
[ 38.628] (++) using VT number
Im guessing thats 11.4. Anyone know how to check that from the command line?
Other than that, I did nothing special. cgminer default settings, intensity 9.
Yeah that is catalyst 11.6. Linuxcoin comes with SDK 2.4 and 11.6 and kernel 2.6.39 AFAIK. |

Something really strange just happened :
It was showing like 60836 shares submitted and 2.67 BTC ( probably wrong ) to be paid now after half and hour when I refreshed it, I get 57 shares submitted and 0.00250794 BTC earnings ( probably right ) ?
I will mine 24/7 at over 1 ghash/s as in the contract with no "hopping" as soon as I can do it. I need to test my miners settings first on another pool that does not mind a little tuning downtime because I just setup them this weekend. I am a man of my word and I will respect the contract but for now I need to tweak my miners then they will be all yours 24/7 at 3.5 ghash/s without any interruption.
I read your recent email and really don't want to be kicked out or penalized etc. I really like the fact you have a UK server so this pool should be ideal for me and my miners !

How did you get 450 + out of a 5870  Im getting ~455 out of mine. 1GHz/300 clocks, cgminer, linuxmint. Please share SDK, kernel parameters etc. so I can see if I can replicate this. It is not that I don't believe you but I need to optimize my miners as well so it would be very good if I can get that as well. Thank you ! |
