^^^^^^^ TROLL ^^^^^^^  hows everyone doing? i haven't read much here in a few days sp_ is working on optimizing (i hope so) cbuchner1 code on ccminer (funnel shift) for speed boost (maxwell card only). actually, it is already done (mostly), Christian has already implemented these things... (at least on the slowest routine...) |

What increases are we seeing on different algo's for it?
Across the board or specific ones?

(at least on the slowest routine...) Source ? U mean its already done and released ? If Christian is doing what sp_ is doing , maybe we should let him know so he dont waste his time doing something that is already done. I think sp_ saw something that can be optimized. Which is why he mention its possible to get speed boost. I am no programmer. |

I am trying inline asm stuff actually on the whirlpool (on xor... ), and basically, I get awfully long compilation and ended up yesterday with a very bumpy gpu usage |

Then i think sp_ is optimizing Christian code because he mention there are missing funnel shift for some algo. By having them on those algo, it will improve hashrate. That is what he said. I hope i am right. Disclaim: I am no programmer. What i said might sound stupid to programmer. |

"We are calling our difficulty adjustment algorithm the Indigo Storm Difficulty Adjustment Algorithm, code-name: The Dickgate - nobody wants to go through a dick gate. That would be very difficult." |

I am mining N5 with cayars nvminer 1.2. Two rigs on Windows 7 64 bit and both using 335.23 driver. Only difference is cpu and gpu manufacturer but way different results. Gpu's are factory overclocked and at these settings. Cpu's are not overclocked.
Rig A: GPU- 5 750ti's (EVGA SC) CPU- AMD Phenom II X6 1100T (cpu usage about 25% usage, avg) Speed: 35,500 Kh/s or 7,100 Kh/s each card MOBO: Gigaybyte GA-890GPA-UD3H
Rig B: GPU- 5 750ti's (MSI OC) CPU- AMD Phenom II X3 710 (cpu usage about 70% usage, avg) Speed: 26,900 Kh/s or 5,380 Kh/s each card MOBO: Gigaybyte GA-MA790X-UD4P
In my Rig A the gpu load stays above 90% but in Rig B gpu load fluctuates between 30-85%. This happens on all cards in each machine. Both machines have the cards on the same kind of powered usb risers. I can't get the Rig B to over 90% load for nothing. This happens now (I never noticed before but Rig B has always been slower) for any algo mining.
Could it possibly be the cpu? Just curious before I drop money on the cpu. I also know the mobo are not the best in the world but they were very cheap when I got the a while ago. I know I can swap cpu's also but would rather get you all's advice/opinions first. I would rather just go and get a new cpu if needed.
Sorry to quote myself but still looking for ideas. @cayars thanks for your advice. Still having same issue on Rig B. I have switched cpu's and the problem did not go away. So I eliminated that. Switched gpus and same issue. I can run 4 gpus on Rig B and everything runs fine. As soon as I add the 5th gpu is when everything throttles down. I have tried 5 different driver versions for Nvidia and no change. Could it be the mobo or a setting in bios? I am ready to just go buy a new mobo and cpu. I am literally out of ideas. |
If you are going to leave your BTC on an exchange please send it to this address instead 1GH3ub3UUHbU5qDJW5u3E9jZ96ZEmzaXtG, I will at least use the money better than someone who steals it from the exchange. Thanks |

I'm not familiar with those motherboards, that said I suspect the power supply. |

IIRC I had a similar problem, though I was just using 4 GPUs, and in my case, the problem was that certain PCIe slots share bandwidth, and do not initialize correctly with multiple GPUs installed (as they exceed the total bandwidth available to the shared slots). The solution for me, was to switch certain PCIe slots to work in PCIe 2.0 mode in the motherboard BIOS/EFI. This had no negative impact to mining performance.
Good Luck!
