Make sure to launch with the -U flag instead of -G.

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.

Where can I get it?

Check the readme on my github. It has Ubuntu 14.04 build instructions. 15.10 apparently is a bit of a pain with CUDA unfortunately

You have to set your compiler manually with Ubuntu 15.10 in the CMAKE line:
cmake -DBUNDLE=cudaminer -DCUDA_HOST_COMPILER=/usr/bin/gcc-4.9

If you install the CUDA tools (cud 6.5 I think) from the PPA, it also installs gcc-4.9 - at least it did for me.

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.

Ok thank you! I was actually wondering if it made a difference for submitting shares!

For 15.10 just run these commands:

cmake -DBUNDLE=cudaminer -D CUDA_NVCC_FLAGS="-ccbin gcc-4.9" ..

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.

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.

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!

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 Huh

Any idea?

There was a bug that for some reason doesn't surface in the Windows build. It should be fixed now.

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 am trying to build the miner on Ubuntu 15.10 to test if it works better there but unfortunately I've got the following error:

Code:

Makefile:116: recipe for target 'all' failed
make: *** [all] Error 2

When I tried to build the version without CUDA it works so I guess it is related to that. I have driver version 352.79. Has anyone built the miner with Ubuntu 15.10?

EDIT: I've got more info by rerunning the make, it is due to the version of gcc being too recent. I've got it working by installing gcc 4.9.

I have SAPPHIRE NITRO Radeon R9 380X 4G D5.

I use ethminer-0.9.41-genoil-1.0.4b3

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_SINGLE_ALLOC_PERCENT 100
C:\Mine\ethminer107\ethminer.exe --farm-recheck 2000 -G -F http://127.0.0.1:8080/dw1 --cl-local-work 256 --cl-global-work 16384

And i have 20.9 m/s.

What settings can i change to improve that result?

change the --farm-recheck 2000 to 200 think might of added an extra 0 by mistake as that is 2 sec and can lose out a lot of shares in that 200 ms is far better on getting shares unless changed it to be improved for 2sec delay. everything else seems to be fine with your settings you have.

When i change farm-recheck to 200 i get 20.3 m/s. Thats a little less. Or that doesnt gains for me more shares?

it is good hashes for 380x , I think

I have pc with 1x Sapphire r9 380x + 1x MSI r9 370

Using ethminer-0.9.41-genoil-1.0.7

Mining without overclocking.

Here are the settings

setx GPU_FORCE_64BIT_PTR 0
setx GPU_MAX_HEAP_SIZE 100
setx GPU_USE_SYNC_OBJECTS 1
setx GPU_MAX_ALLOC_PERCENT 100
setx GPU_SINGLE_ALLOC_PERCENT 100

Getting float result from 30.2 to 34.5 to 38.9.

What can i do to make it more stable?

And what can i do to gain more H/s?

Is --farm-recheck 1200 good timing or i need to reduce it and why?
