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:
Code:
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: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
On the 110 branch or remove the -b 110 once it goes main.
Code:
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. Code:
nano ~/ccp-ethereum/libethash-cuda/CMakeLists.txt
And then compile.Code:
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 ~)make -j8
Hope it works for you.
Where the link download for windows version? i want to try it
https://github.com/Genoil/cpp-ethereum/tree/110/releasesMy 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.cmake -DBUNDLE=cudaminer -DCOMPUTE=30 ..
And I also tried:
cmake -DBUNDLE=cudaminer -DCOMPUTE=52 ..
Example, mine now looks like:
Code:
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:
Code:
set(CUDA_NVCC_FLAGS ${CUDA_NVCC_FLAGS};-gencode arch=compute_50,code=sm_50)
Then try your cmake, with just:Code:
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.

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 -GAlso, 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.
https://github.com/Genoil/cpp-ethereum/blob/110/libethash-cuda/CMakeLists.txt
Remove the bits with '61' in them, or better, only leave 35 and 50 in.
Much thanks!

I pushed a new 1.1.2 binary to the 110 branch. https://github.com/Genoil/cpp-ethereum/tree/110/releases
Added 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

I compiled with:

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

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
- GeForce GTX 780 Ti
cudaDeviceProp::totalGlobalMem: 3220504576
[1] GeForce GTX 750 Ti

(I would test, but I'm away from the rigs atm) Thanks.

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.I have a problem with the compilation version 1.0.8 on Ubuntu 14.04. After copying the command

1.0.8 is out.
Thank you for this build. So far working great on Ubuntu 14.04 and Mint 17.3 rigs.Re: BAMT version 0.5 - Easy USB based mining Linux with farm wide management tools
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.
https://bitcointalk.org/index.php?topic=65915.msg3885542#msg3885542Hi 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.It seems it has no sense to mine because I lost my monet... probably do I miss anithing?
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.

Re: [WTS] GridSeed PCI-E Modded Power Cables by Lutro0 Customs [Lifetime Warrantied]
Order was received, but a slight shipping delay, weather based, can't really fault them for that.
All the cables were assembled with care and maintained a high level of quality with an attention to detail. I'd order again from them if I need more.

Re: [GUIDE] GridSeed GC3355 5 Chip Setup/power/windows/linux/rpi by UnicornHasher
Hey guys I didn't know where else to ask this question so I'll ask here and sorry if it's already been answered.
I have 3 gridseed modules 2 of them are stable at 900mhz and the third on is stable at 850mhz is it possible to run different modules at different frequencies? If so how can I manually set each frequency in cgminer? I'm not using a controller I just have them plugged into my computer windows 7 thanks in advance!

Yes if some one could point to the fork that this has been working on best that be awesome. im running them on linux./
I found this online --gridseed-freq 6D9426984857=988,6D9656774857=975,6D8956965251=975
But when I put that in my .bat and launch cgminer just crashes

Re: [ANN] CryptFolio.com - keep track of your cryptocurrencies! (BTC/LTC/NMC/...)
Could you look into adding ScryptGuild to your mining list
Yes, please.Also, any plans or progress for PoS type assets? Like BitShares PTS or NXT?
