Re: [Parts Check] Need input on a Litecoin mining rigProbably a little higher than a Radeon 7850, I'd guess 400-450 kH/s. Once someone figures out how to get Linux running on it, the rest should be trivial. Apparently it works on the PS3 and gets respectable hash rates using the Cell's SPEs, at least compared to modern x86 CPUs. |

if you really want to go for it you'll want to try for a TESLA K40 (12GB vram based on the same GPU as a GTX780) » litecoin.info/Mining_har ··· mparisonTesla K40c - 188 KH/s My 7970 can do 565 Kh/s. edit: Looks like a 780 Ti can even get 430 Kh/s |

ok that doesn't make sense. I looked at the list and the chip is the exact same as in the K6000 so I think that might need a re-do there should be that big a gap with the same chip |

the K40 and the K6000 are the same chip so what up with the diff here. |

and you left off a 1
188KH/s not 88 where as the same chip in the K6000 package does 485KH/s
maybe some tweaking on teh miner is needed or the settings they used were off |

well with the K6000 doing 485KH/s that beats the GTX780 btw look here » www.nvidia.com/object/qu ··· pus.htmland » www.nvidia.com/object/te ··· ers.htmland » www.geforce.com/hardware ··· icationsand » www.geforce.com/hardware ··· icationsThe K40, K6000, and GTX780ti have the same number of cuda cores, though the GTX is likely a higher clockrate and less memory (and the GTX doesn't have ECC emeory and has some parts of the chip disabled making it less good at OpenGL) so based on that and the table showing the K40 and K6000 not matching tells em that someone goofed, the only diff between the K40 and K6000 is the K40 doesn't have video outputs. though if your AMD @ $200 is doing more than 500KH/s without OC (you know for apples to apples) then its a good value for litecoin. another catch the K6000 and K40 aren't 4k they're more like 5-8K, but that's not really important. (I'd still love to have a K6000 card. |

My AMD 7970 was $450 new, and they go for as much or more now.
New 280X's (7970s on steroids) are about $420 and get high 500s to 700 Kh/s.
I get 565 kh/s with a custom scrypt file that was fine-tuned to my Sapphire Vapor-X's. 1725 memclock, 1081 core clock. 1725 was as high as I could go on stock voltage, and I believe it crashed this afternoon, so I need to go home and troubleshoot the rig and perhaps back off to 1700 memclock and then fine a new good core clock.
7970s (and likely 280X's) are unique in that they are very overclockable, but you need to take the time to get the core clock exactly right. It is so finely tuned that one Mhz higher will cause a 20% drop in kh/s. My drop wasn't so severe, but you want core clock to between 0.57 and .65 of memory clock speed. |

Your daily profit is 0.0083 BTC (~$6.63) less power costs ($0.32). is that for one 5GH/s unit or for all 3? |

Well be sure to give it plenty of cooling, its been found that higher error rates are seen at higher operating temps and while in gaming that's no biggy in GPU computing its important.
If that hash you just made is in error you just wasted GPU power (part of why pro cards for CAD tend to have ECC memory, to ensure accuracy of the work, and also why they're lower clocked) |

So maybe in 4 months I might have some money. I think I'll get a USB hub and run them off my 380 (any issues using Server2003 x86 ent for rnning the BFL units?) |

I believe it crashed today though, and while it didn't provide any incorrect errors, a crash is still a crash. |

I'm no expert on ASIC mining, but I don't see any issues with it. Linux or Win7 are preferred, however. I do it fine on 8.1 Pro. You could look at the hardware comparison page all the way on the right and see what their setup was in terms of OS. |

Well the DL380G4 is an HP server and as such it'd be a pain trying to get drivers loaded for a desktop OS
I'd have to get the raid controller drivers ready for during install then hope that the drivers aren't coded to not be accepted by the consumer OS. (ran into that before and it can be a pain) |

What mining program will you be using? |

Not sure, figure I'll start with easy miner but after I migrate all the services off my DL380 I think I might reload it with linux |

Well drivers failed to load on 2003server so I connected 2 of them to my main computer to test they're doing 7GH each I need to go get a USB hub and do some stuff to clean up for long term setup I think I will go with reloading the 380 with Linux after I migrate off it and then use it for running my miners ok I went ahead and connected the 3rd now to open my wallet again and let the Bchain update... |

I just migrated to Hashco.ws instead. That way I can track my hashing power. |

I control-f and enter my wallet ID to find my hashing power on Middlecoin. I also see that Hash Cows advertises what coin they are mining (dogecoins right now). Interesting that they tell you, but middlecoin keeps it a secret. Let me know what your returns are and I might swap over. I see BTCs took a crap overnight. 547 USD per BTC? Blech. |

well bitminter seems to have an issue, after awhile it said no more work and stopped
can somone help me get easy miner working with bitminter?
I want my 20~24GH/s to keep at work (its peaked around just over 24GH/s and hasn't gone below 20GH/s) seems BFL's fab has gotten good and now most of their chips at Bin A chips which do 7GH/s so I basically got a 2GH/s upgrade for free.) |

You need to set up a failover pool. I don't know how bitminter works, but cgminer is like:
--scrypt -o stratum+tcp://url.com -u username -p password --failover only -o stratum+tcp://backuppool.com -u username -p password
That way if your primary pool goes down, your worker switches over to your backup. |

Probably slightly less power draw on the Intel platform, but one more full-length PCIe slot on the AMD one. I'd say go AMD for that and the slight novelty factor. |
