does anyone have managed to run 6 x 750Ti under debian with cudaminer? I read somewhere it's hard to run more than 4 cards under linux, but havent tested it myself yet.
https://litecointalk.org/index.php?topic=16800.0ive got a 6x 750ti rig running right now using this. gigabyte windforce gpus on a z87-g45 mobo... trying to get a 7th gpu to recognize. http://s24.postimg.org/w2vn8c1p1/IMG_1088.jpg |

ive got a 6x 750ti rig running right now using this. gigabyte windforce gpus on a z87-g45 mobo... trying to get a 7th gpu to recognize. I too, have (a couple) of z87-g65 motherboards filled up with Windforce 750 Ti's, trying to squeeze a 7th card in doesn't even post. The screen looks and behaves like a NES cartridge with dust before the bios can even load. Let me know if you make any progress. |

Let me know if you make any progress. i had to change the bios settings for pci-e speed to Gen2 for the three pegs, for it to post.. I also had to change to gen2 for cudaminer to be stable with 6 cards under win7. Interestingly enough with 6 cards on gen3, one card would always under perform, while the other 5 would have hashrates from 350-400. The CPU would choke on all the interrupts and everything would eventually crash -- but it was nice to see hashrates that high, even if they were exaggerated. Now that I am stable on gen2 though, maybe I'll try that 7th card. The best cudaminer config for this type of setup is: -i 0 -l T5x24 -m 1 -H 2 -b 4096 |

Sooo looking forward to the rest of the maxwell cards and maybe building a mining rig of a few!  |

gtx 880M (for laptop) is this a maxwell or still the older generation (got an ads from msi... ) ?

Pretty nice table of next gen mobile cards:  Notice that they ALL consume less energy |

we've accelerated 4 out of 5 hashing algos for HVC, but the last one (Groestl) is causing us a bit of trouble. Our first port is actually slower than the CPU - at least on my system. Running Groestl on CPU and the rest on GPU I am getting an 800% performance boost vs. running the CPU alone. Multiple CPU threads can even share a GPU  Note that overall HVC is *not* CPU-only. They really need to change their advertising, and change it quickly. Whatever they did to SHA256 to turn it into a "GPU and ASIC resistant" HEFTY1 algorithm - it didn't work as they intended.

Christian Who, exactly is "we"? You and nVidia? Anyway, excellent work! Will there be a fancy countdown timer for when you release it? |

Me and another German co author (first name is also Christian). We met through Skype and there is a good synergy going on. We're developing in night shifts to get this done quickly. We're not actually working on cudaminer here. It's a new project. There is no decision about a release strategy or date yet. It could be that we will be GPU farming solo for a week before doing a public release (provided that we achieve the necessary speed-ups for this to be worthwhile). I've got an apartment to pay off, you know Christian |

Does your 750Ti's does have an additional power connector (6-pin pci-e power)? |

What hash rates are you getting on your hardware? Just want to compare... something. AMD Phenom II X6 1055T - CPU standalone ca 95 kHash/s on 6 threads AMD Phenom II X6 1055T using the first 3 GPUs in the machine and 6 CPU threads: close to 800 kHash/s (Groestl remains on CPU) cannot get GPU use readings, as GPU-z has decided to always crash on start after the previous driver update (revision 334 drivers I think). Currently running R 335 drivers from nvidia. |

Currently running R 335 drivers from nvidia. Nice, imagine that paired with a better cpu...:p My X79 rig is ready! Christian, did you think about adding a fee in the program, similarly to all those protoshares miners for ypool do? That would make it more profitable for you to share the software earlier perhaps. Say a 2.5% fee. That would be fair. |
