Ok, thank you for the help.
My other pc with the 7970 is ok with about 18 MH/s. But I can't get more than 2 MH/s with my GTX 670... Maybe because of Windows 10 even with 347.52 and cuda 6.5? The pool doesn't even see the worker!
I think 670 should do 8-10 mHashes My GTX 660 (192bit) does 12MH on Windows 7 with a little help from MSI Afterburner. I also have a GTX 650 that does 4MH on the same box.

I build ethminer 1.0.7 for linux and when i start the bash file: ([OPENCL]:cl GetProgramBuildInfo(-33) [OPENCL]:clEnqueueWriteBuffer(-38) With 1.0.6 it worked perfectly but stratum was inestable. I'm using 5x r7 265 cards on Lubuntu 14.04 LTS. My bash file: #!/bin/bash export GPU_FORCE_64BIT_PTR=0 export GPU_MAX_HEAP_SIZE=100 export GPU_MAX_ALLOC_PERCENT=100 export GPU_USE_SYNC_OBJECTS=1 export GPU_SINGLE_ALLOC_PERCENT=100 ethminer -G -S coinotron.com:3344 -O user.worker:x --cl-local-work 128 --cl-global-work 8192 -E old i did the test with same bash file using official ethminer and it works fine Any idea? There was a bug that for some reason doesn't surface in the Windows build. It should be fixed now.

Ok, I've got my 670 working on Ubuntu. Hashrate is 13-14 MH/s with farm-recheck at 2000 and it is oscillating between 10.2 and 20.5 (one or the other, never in the middle) when using farm-recheck 200. Which one should I use?
Thanks for the great miner Genoil!
Another question: is it possible to connect to other pools than ethermine? I can connect to nanopool or dwarfpool but I get endless Waiting for work package... Do I need to remove DAG file or something?
If you use getWork protocol (-F flag) then farm-recheck should be 200, or whatever the pool you are mining against recommends. If you use stratum, then the only thing farm-recheck really does is set the console hashrate output interval. If you set it to 2000, you get a much more accurate hashrate figure because the sampling period is longer. You can connect to any pool you want, except dwarfpool stratum. It uses a proprietary stratumish protocol that I'm not planning to support.

Thanks for the stratum implementation in your miner!

20.9 is pretty ok for a Tonga GPU
I Genoil, I,ve a rig with 4 GTX750ti mining ether. I read that hashrate for a GTX750ti is about 7-8 MHs/s each GPU, but I only reached 15 MHs/s with all four GPU. How can I rise a little bit my hashrate? Thanks.

do the pools show real hashrate ?

How can I rise a little bit my hashrate? Thanks. The GTX750ti did about 8-9MH/s on day 1 of Ethereum. After that the speed declined, like many other cards. 4MH/s per card now seems about right. Make sure to launch with the -U flag instead of -G. I think the default block and grid size I use now are more suitable for GTX900 series. If i remember well (sold my 750ti), good values for GTX750 are -U --cuda-block-size 64 --cuda-grid-size 8192 or 16384. do the pools show real hashrate ?
Most pools calculate hashrate based on the number of shares submitted over a longer period. Because luck plays a big part in this, it often fluctuates around the actual hashrate. In my opinion the most 'real' hashrate is the rate calculated over a very long period, i.e 24hrs. Especially with different mining clients now popping up, you should be comparing what the rate is poolside, because different clients use different methods of calculating the hashrate. Of course the same thing applies when comparing pools. Different pools will calculate it differently. So ultimately you should be looking at your ETH balance.

Genoil, thanks for your answer. If I use -U flag ethminer give me the message "invalid argument", so I think that CUDA is not installed on my system. Do you agree? How can I check that? Just in case where can I download CUDA? I forgotten to tell you before... my OS is Ubuntu 15.10, I don't know if this is important.

You have to install the CUDA toolkit and run cmake with the -DBUNDLE=cudaminer option.

OK gents, all that is over my skills Thanks a lot for your help but, at the moment, I think to continue to mine with OpenCL and my 15 MHs.

You cannot use CPU to mine the Ethereum, you will not earn the electricity you spend on the mining.

how to mining eth use laptop help
You cannot use CPU to mine the Ethereum, you will not earn the electricity you spend on the mining. SOME OF THE NEWEST MOBILE GPUS ARE GOOD-- But I don't have a laptop that is new. I just know that there are capable nVidia mobile GPUs that will mine ETH. Usually, the user will have to watch the laptop carefully to prevent overheating. --scryptr

Hello. I recently switched to this miner. In the new version has appeared start.cmd file. Tell me please what to do with it? It is replacement .bat file?
p.s.: Win7-64, R9 280

You can ignore it. It's like a bat file but it was for my own testing purposes.
