I am using this to mine PPCoin on coinotron. The setup is the same as in my post #195 . There were 144 this Found nonce 3FD7CA5E
2013-05-05 13:54:53 Found Hash!
within a period of 100 minutes. But coinotron only reported 19 shares. What is really strange is that the average kh/s reported by coinotron agrees with the hashrate printed by the miner on average. That means the rate at which my miner finds shares seen by the pool is correct, but the "Found Hash! " is 7-8 times too often. Why is that? EDIT: earlier port # I have never test the miner with PPCoin. It looks like many rejected hashes. |

I just tried this on c2075. The result agrees well with the c2050 card (107mH/s). There is fluctuation (from 70 to 140).
The fluctuation come from you "slow" card. The summery is build every 30 sec. It can be that some times the count goes to the next or previous intervall. A drop is also possible if you get no connection to the getwork server. The best is to use the http://mining.bitcoin.cz/mining-proxy-howto stratun proxy. If you use them you get better and smoother results. psychocoder |

Hello, im getting 0mhash/s on both psychocoder-germany and cdmackie. I have no idea whats going on.
Please post the first 30 lines output of the program in this forum that we can help you. |

i have a GTX Titan and i got only 360MHash/s with 1150mhz gpu clock, is it possible that i get more MHashes with linux ?
changing -gputhreads=x has no effect on the rpcminer :/ it stays by 256
Can you please add the full name of your grafic card! Our post a link to the shop and product were you have board the gpu. I think there is no GTX Titan with 1150 mhz. I my theoretic calculation a GTX Titan with 1150mHz must get 500+ MHash/s. Please post the first 20 lines output from rpcminer thats help me to see why you Hashrate is so low. And yes the paramater -gputhreads=x is disabled because the kernel are compiled for 256 threads only. |

I can't even get it to run. I get unable to load cuda module error. When I try compile the module myself per the instructions...I get this error:
LIBCMT.lib(crt0.obj) : error LNK2019: unresolved external symbol _main reference
d in function ___tmainCRTStartup
a.exe : fatal error LNK1120: 1 unresolved externals
No one can tell me how to fix it. I'm not much for a programmer..
Is your driver up to date? If not please upodate your driver and run the precompiled version. |

I am waiting for the 700 GPUs to come out, or get a deal on another titan.
Psycho So none of the Kepler Base Quadros can do this either?
I think so, but I think there is no Quadro out with K20 architecture. At the moment the GTX Titan is also to expensive to buy. |

So the thread says going from 134 - 330.. I have yet to see any sort of leap from using other miners or rpcminer at default. I realize that people are working on functions to try to improve that and their efforts are greatly appreciated but, I think all of us would like to see a nice bump in our mining with our nvidia cards.
thoughts?
134 MHash/s to 330 MHash/s is for a Kepler K20 or the consumer version Titan. A big jump with old NVIDIA GPUs is not possible. CGMIner is very near to the maximum power of old NVIDIA GPUs. Al GPUs before Titan has no funnel opertor and need 3 operation for a rotate, the new one need one operation. Ahh ok sorry my bad, thanks for the clarification.. so your saying the 690's and below will still be somewhat limited or same speed with out much boost? I have a gtx 680.. GTX 680 IS a Kepler.. Onyl Kepler equal or higher than titan GPUs. GTX680 is K10 architecture, you can say it is a better fermi. K10 has no funnel operator :-(. Thay have the same amount of 32Bit registers and a lot of opration have the same speed than a k20 but the importend operations are not available. |

@Ephebus :
You get better performance if you set -aggression= to a bigger value and -gpugrid also to bigger value. But than you desktop is not smooth. Do you tested also a other miner?

thanks sir it's working now  but my computer gets really slow it is normal? my old hashrate is 101.5mh/s but now it's 179mh/s im using gtx 660ti oc ed. Is its right that you now faster than before? 101->179 MHash/s With which program you get 101 MHash/s, is it up to date? |

i have compiled a windows version of the miner everyone who wants it send 0.5 btc to my adress and pm me 1ChFy7a3Lsyt3JkgG2NVWXBP4Yebs1YcVV Willing to Escrow? Screen shots? Support for future updates?
https://bitcointalk.org/index.php?topic=162803.0;allThanks for the information. Nobody must pay for a binary of a open source software. If someone will pay than our BTC address can found in the signature. All developer, Tester and and and do it for the community!!! |

I've got a GTX 670 and 50miner (via poclbm or cgminer) gives me about 92 mH/s. I'm wanting to see what this does
I'm going to ask a real noob question here, but where do I extract the 7zip files to? Clicking on the .exe from the bin just causes it immediately open and then stop working, and I can't input any parameters.
Tomorrow I write you a simple Bach file To Start the Programm. |

Can you run the miner same minits that we can see the hashrate. My driver under windows also crash, thats windows like shutdown^^ my results for 560ti

Plese use -aggression=6 as parameter, the gpu is to slow and braek the kernel run limit. |

@InqBit: is 137694 khash/s the first shown hash rate? Please run the miner 5 min and than look to the hash rate. The first hash rate is always lower because the first kernel call takes very long.
I see you run the code with without -aggression, please add -aggression=8 or 7 to you parameter to get more performance. -gputhreads is not needed because it is ignored and hard set to 256.
theoretic calculation rate for GTX480: 1401*15/(3733/32+1194/16)=109 MHash/s (magic numbers are the count of operations from the binary for this implementation)
Mhh in my theoretic calculation I assumed 109 MHash/s for a GTX480. I think I must check if my operation count for fermi is right.
Can someone with a GTX480 run the code under linux without -gpugrid.

@charliemaggot
I have updated bitcoinminer.cpp in my repo. I disable the hard crash if a error came out of the device selection. Normaly if no cudaSetDevice is called the driver select the first device. I have not tested the code because I do the changes in my webbrowser, but I think it compile^^

I have deinstalled my cuda and run it under windows withe the dll from the repo. All worked fine.
Can you please post the commandline which you use to start the miner and all output from the miner.

Mh, the selection of your device crash. I add later some more output which device is selected. In most cases there is a problem with the driver. |

Were the 22.3-22.9 values you got on your GT555M in Windows what you expected? Is it the same as Unix? Can't test it under linux. Thats a Laptop with 2 GPUs it was not possible to run the miner under linux :-( I hope we get some results from a user with a GTX Titan. |

HI, I have testet the windows version on Windows7 64. I start the program and the cudart32_50.dll or cudart64_50.dll was mist. I install cuda for windows https://developer.nvidia.com/cuda-downloads and than all run. It can be that this is a sideeffect from switching to runtime library of cuda. If an error shows that bitconminer.cpp:174 crash that the parameter -gpugrid to 256 or 512, it came from windows intern limit that no calculation on gpu can run longer than 4 sec. With GT555M I get: 22.3 - 22.6 MHash/s with OpenCL 22.3 - 22.9 MHash/s with CUDA I put allw links to reposetories and Errors to the top post. |
