Thread: [solved] overheating after upgrade
Post: [solved] overheating after upgrade
| I have 3x 7970 in a case. I have two of these machines, both with the same issues.

Thread: [solved] overheating after upgrade
Post: RE: overheating after upgrade
| Well the default for that is 80, right? That seems like a fine place to have it to me, but my cards blow right past that without even slowing down with this new version of software. |

Thread: [solved] overheating after upgrade
Post: RE: overheating after upgrade
| Thanks K9, I see what's happening. I hadn't noticed the fans weren't turning on. I set gpu-temp-retain to 65, and we're working well!
One more question. Does the gpu-temp-retain actually slow down... |

Thread: Multi GPU clustering
Post: RE: Multi GPU clustering
| VCL is dead - it does not work, but that was for clustering multiple GPUs on different machines. You should have no problem with multiple GPUs on the SAME machine. Hashcat handles that by default. You... |

Thread: is there still support for VCL?
Post: RE: is there still support for VCL?

Also...can you expound a bit? VCL just isn't being updated anymore? It wasn't worth making hashcat work with ... |

Thread: Cards not cracking at the same speed
Post: RE: Cards not cracking at the same speed
| I don't know about running in Windows (I use Linux for cracking), but I can say you're running WAY hot, and that could have something to do with it. |

Post: RE: Cards not cracking at the same speed
| By emergency shutdown, I meant hashcat's default for the AMD cards. I was not aware that different vendors would have different heat tolerances. |
