G1000 Powering 4x 280x and 2x 23cm fans with ease. GPUs @ 1080/1500. 2.95Mhs total. The frame will be a closed case soon. Work in progress.  What 280x's are those? Look like VTX3D |

Moved one of my October Bitfury rigs into a Spotswood case. The structural stability of the case provides a ~5-10GHs increase in hash-rate vs not having the rig cased.  |

Today i got power meter and did some tweaking. 2.95Mhs = 4x 1080/1500 @ 1.125v = 1200W from wall. 2.85Mhs = 4x 1030/1500 @ 1.08v = 1050W from wall. Sacrificed 100khs for -150W. Since my PSU is Lepa G1000, i settled for 1050w. However 1200W from wall was perfectly stable too. |

How does that work? |

How does that work? I'm not sure, but I do know heavy boards like GPUs with bad heat sink designs can flex the card deteriorating the thermal contact with the GPU chip. Either that or more directed, controlled airflow helps with temps a lot. 5-10GH over that many miners really isn't much. |
Please DO NOT send me private messages asking for help setting up GPU miners. I will not respond!!!

How does that work? The Bitfury rigs can be delicate to say the least. Very sensitive to card-wobble. |

Imagine how you would feel if you find a block  Please tell me you are mining solo, otherwise there is no point really |

How does that work? Placebo effect. |

How does that work? Placebo effect. Possibly ? *shrugs* All I know is, it appears I've gone from an average of 560GHs to 569GHs on that one particular rig since casing it properly. Before that, I had it laying on it's side with fans sitting directly on the cards blowing air down on them. It's all very mysterious and sounds suspicious to be sure. I'll have more anecdotes once I get the second rig cased over the weekend.   |

I'll be keeping an eye on this thread, I'll be interested to hear your findings.  |
