Hi I picked up my first 980ti to add into the farm. It sounded like a good idea at the time but does not seem to be performing as well as expected. (Compared to my others - 950/960/970) I'm only getting around 18MH/s and it sounds like I should be getting more. It's running on Mint 17.3 with ethminer 1.1.4, does anyone have any suggestions for the optimal command line options? If I can't get better then that I might as well return and get a 970. Thanks for any help.
You should be able to get 20+ by forcing the card into P0 state: http://cryptomining-blog.com/7341-how-to-squeeze-some-extra-performance-mining-ethereum-on-nvidia/But it won't be much faster than a 970, so that's a better use of your money. Thanks for the tip. |

@BitminerN8 Thanks for the input. I had seen the note from Geniol to you and I had removed those references in that file. Still had the same issue so I suspected drivers. Made the mistake of trying to install the .run file then couldn't get X Win to let me log back in with Ubuntu. Found some references to messed up perms on .XAuthority and a few other things. Nothing worked.
So back to the drawing board, I just blew the box away and starting from scratch. Hopefully I can get some working drivers and then try to install Genoil's miner again... I swear, sometimes you cannot win for losing... It has been a nonstop battle with this rig... It is a new build and I did not have it running on 1.0.8.
Thanks again for the feedback.
No worries, my linux skills are not that great, but I try. These are the steps I have used on my Ubuntu 14.04 rigs. (I think I got from a readme or faq from a mining pool) Feel free to try this it if it works for you great. Again, I'm no expert, just collect stuff that works for me. From a fresh install: wget http://developer.download.nvidia.com/compute/cuda/repos/ubuntu1404/x86_64/cuda-repo-ubuntu1404_7.5-18_amd64.deb
sudo dpkg -i cuda-repo-ubuntu1404_7.5-18_amd64.deb
sudo apt-get -y install software-properties-common
sudo add-apt-repository -y ppa:ethereum/ethereum
sudo apt-get -y update && sudo apt-get -y install screen htop git cmake libcryptopp-dev libleveldb-dev libjsoncpp-dev libjson-rpc-cpp-dev libboost-all-dev libgmp-dev libreadline-dev libcurl4-gnutls-dev ocl-icd-libopencl1 opencl-headers mesa-common-dev libmicrohttpd-dev build-essential cuda
IIRC you need to reboot, then continue: On the 110 branch or remove the -b 110 once it goes main. git clone -b 110 https://github.com/Genoil/cpp-ethereum/ && cd cpp-ethereum && mkdir build && cd build
This is where you then need to edit ~/ccp-ethereum/libethash-cuda/CMakeLists.txt to remove references to 61. nano ~/ccp-ethereum/libethash-cuda/CMakeLists.txt
And then compile. cmake -DBUNDLE=cudaminer ..
make -j8
If it builds with no errors, the compiled ethminer will be in the ~/cpp-ethereum/build/ethminer folder. I just copy that to my home folder and run it from there. (cp ethminer ~ && cd ~) Hope it works for you. |

My options in cmake are:
cmake -DBUNDLE=cudaminer -DCOMPUTE=30 ..
And I also tried:
cmake -DBUNDLE=cudaminer -DCOMPUTE=52 ..
Well as a test, had the 108 (current default git) been working for you? I had an issue with 110 (compiles as 1.1.2) crashing, Genoil advised me to go into this folder ~/ccp-ethereum/libethash-cuda and modify the CMakeLists.txt to remove references to 61. Example, mine now looks like: set(CUDA_NVCC_FLAGS ${CUDA_NVCC_FLAGS};-gencode arch=compute_35,code=sm_35;-gencode arch=compute_50,code=sm_50)
But if you only have 750ti, you should be able to just use: set(CUDA_NVCC_FLAGS ${CUDA_NVCC_FLAGS};-gencode arch=compute_50,code=sm_50)
Then try your cmake, with just: cmake -DBUNDLE=cudaminer ..
I don't think the other options will be needed anymore, I didn't need them since that is what I edited out. If none of that works and I'm not helping at all, can you try starting with the -G and see if opencl is working? At least that way you know the drivers are at least loaded and seen. Maybe we can go from there. Also, what flavor of Ubuntu? I'm using 14.04 as I could not get it working on 16.04. |

Ok, I didn't see anything that stood out in the mass of messages going across the screen when trying to install on Ubuntu. But something must have gone haywire. I get the following when I try to run the executable:
CUDA error in func 'getNumDevices' at line 112 : no CUDA-capable device is detected.
terminate called after throwing an instance of 'std::runtime_error'
what(): no CUDA-capable device is detected
Aborted (core dumped)
Any ideas where I missed something? I used the 110 branch. This machine has the 750ti cards in it, but appears it isn't detecting them? Right now I only have one card connected.
What options did you use on your cmake? Example: cmake -DBUNDLE=cudaminer .. |

It's kind of weird that that worked. Better for you to -DCOMPUTE=0 and remove Compute 6.1 from Cmakelists.txt in libethash-cuda folder.
I stand corrected, it did not work with 1.1.1, my mining script was still calling -G Also, I looked all over and can't seem to find a Cmakelists.txt in libethash-cuda folder, should it be there after the cmake? Thanks. Remove the bits with '61' in them, or better, only leave 35 and 50 in. This worked. I'm now doing this per rig with just the flavor of cards in it. Much thanks! |

I pushed a new 1.1.2 binary to the 110 branch. https://github.com/Genoil/cpp-ethereum/tree/110/releasesAdded mixed CL/CUDA mining, so you can mine both GPU types on a single ethminer instance. It's not possible to set different local/global work per GPU type yet. Will add that if there's any demand. I added this mostly to be able to build and test the DAG generation serialisation, because I have only 1 970 and 1 7950  . To enable, replace -G or -U flag with -X. Hi it seemed to compile ok, but I'm getting the following using -U Using device: GeForce GTX 780 Ti (Compute 3.5)
Using device: GeForce GTX 750 Ti (Compute 5.0)
Cuda error in func 'set_constants' at line 143 : invalid device symbol.
Cuda error in func 'set_constants' at line 143 : invalid device symbol.
Segmentation fault
I compiled with: git clone -b 110 https://github.com/Genoil/cpp-ethereum/ && cd cpp-ethereum && mkdir build && cd build && cmake -DCOMPUTE=52 -DBUNDLE=cudaminer .. && make -j8
That was working on 1.1.1 yesterday. Thanks for looking into it. |

Genoil, I tried the new release, checkout the 110 branch.
Now I get a new error: [ 61%] Building NVCC (Device) object libethash-cuda/CMakeFiles/ethash-cuda.dir/ethash-cuda_generated_ethash_cuda_miner_kernel.cu.o
nvcc fatal : Unsupported gpu architecture 'compute_61'
I'm getting this error too when trying to make the 110 branch with -DBUNDLE=cudaminer .. Running on Mint 17.3, all other versions worked prior. This is because the default list of supported compute platforms now includes Compute 6.1 for the 10x0 series. It requires CUDA 8 RC to build. If you don't want to install CUDA 8, you can add -DCOMPUTE=52 to the cmake line to support only Compute 5.2 devices, -DCOMPUTE=30 to support only Compute 3.0 devices, and so on. Ahh, thanks, makes sense now. Is there a way to support 3.5 and 5.0 on the -DCOMPUTE? For example if I have: Listing CUDA devices. FORMAT: [deviceID] deviceName Compute version: 3.5 cudaDeviceProp::totalGlobalMem: 3220504576 [1] GeForce GTX 750 Ti Compute version: 5.0 cudaDeviceProp::totalGlobalMem: 2147287040 (I would test, but I'm away from the rigs atm) Thanks. Got in remote. -DCOMPUTE=52 seemed to work for both cards. (3.5 & 5.0) |

Hi, I have a problem with the compilation version 1.0.8 on Ubuntu 14.04. After copying the command git clone https://github.com/Genoil/cpp-ethereum what you need to do next in order to properly compile the program? Thanks in advance for your help If you click on that link above in your post and scroll all the way to the bottom, there is a heading Building on Ubuntu. Is that what you are looking for? I've used those steps on 14.04 for both AMD/nVidia and they work great. |

1.0.8 is out.
Thank you for this build. So far working great on Ubuntu 14.04 and Mint 17.3 rigs. |

The pool server is now down. Coins will be shuffling back and forth between the local pool wallets and the exchange over the next few days to keep withdrawals functioning. If you do not want your coins to be force-converted to BTC, you should set a wallet on them and a payout threshold. Once the majority of users have withdrawn their balances out the full wallets will be liquidated in order to shut down the coin daemons.
Thanks for running this pool. It was great to dust off a stack of old GPUs and make some BTC while it lasted. Best of luck in your future endeavors.  |

Can someone link me to the copies of BAMT which do not steal? Heck even looking for a non scrypt specific copy too =\ a List of links to NON thieving confirmed copies of BAMT in one place would really be a useful resource for the community imho. IF there already is one, let me know.

How do I remove an address from my wallet? I want the site to auto convert for me
To enable automatic conversion, on the left hand side, 5th button down, Convert to BTC. That is the on/off switch for it. You can still have addresses in the Wallets but you would only use them if you hold a reserve and then select a payment threshold. For example, say you wanted to hold all DOGE mined to go to your wallet, but auto convert the rest. |

Hi BitMiner and thanks for the link.
It seems it has no sense to mine because I lost my monet... probably do I miss anithing?
If you are looking to make a lot of money, I believe that ship has sailed. If you are looking to just learn and play with the technology, then a small USB powered ASIC and a Raspberry Pi running Minepeon would most likely get you going. It is fun to play with the mining hardware and get it all working. It really depends what your budget is for this project. Just don't expect to make much BTC if at all. Maybe some others can send links to some products that might fit your need, I have not researched it for many months. |

hi guys,
I am new and I want to know if using a raspberry pi and a Bitmain AntMiner U2: 2Gh/s USB Bitcoin ASIC miner it is ok to mine bitcoin or if the HW is not enough for that.
I am looking forward to read your answer before buying that.
Thanks a lot in advance.
You might want to use one of these calculators to help determine ROI. http://www.alloscomp.com/bitcoin/calculatorhttps://tradeblock.com/mining/You can then make a better financial decision. |

Can anyone help me?
I running cgminer 4.2.2 but it's only finding work and draw 0.00MH/s speed...
I'm looking forward to your answers!
Thanks
I don't think cgminer past version 3.7.2 supports scrypt. So i should use a cgminer with version of 3.7.2 or less? If using it to mine with GPUs/Scrypt ASICs and need the --scrypt command line option for use on a pool like this, yes. |
