Updated Ethminer 0.9.41 Nvidia CUDA Version for Windows
9 Sep2015
The developer of the Ethminer fork with Nvidia CUDA support (source) Genoil has released another update and we have compiled a new Windows binary of ethminer with CUDA support. Do note that this Windows binary release is compiled with VS2013 for windows 64-bit and is for CUDA 6.5. The latest version comes with some optimizations and a new command line option cuda-schedule to experiment with that replaces the old cuda-turbo, also note that you may need to manually specify the number of GPUs to use if you have multiple video cards using the cuda-devices command line parameter if the miner fires only on one device by default. Additionally to get better performance you can try adding the following command line parameters to the ethminer:
For OpenCL:
--cl-global-work 16384
For CUDA:--cuda-grid-size 8192 --cuda-block-size 128 --cuda-schedule auto
--cuda-scheduleSet the schedule mode for CUDA threads waiting for CUDA devices to finish work. Default is sync. Possible values for mode are:
auto– Uses a heuristic based on the number of active CUDA contexts in the process C and the number of logical processors in the system P. If C > P, then yield else spin.
spin– Instruct CUDA to actively spin when waiting for results from the device.
yield– Instruct CUDA to yield its thread when waiting for results from the device.
sync– Instruct CUDA to block the CPU thread on a synchronization primitive when waiting for the results from the device.
It seems that the auto mode for cuda-schedule works best for us providing maybe a bit lower maximum hashrate, but a more stable one than the sync that may produce higher maxes, but also lower. You are free to experiment what will work best on your mining configuration however. The Ethminer CUDA fork should work on Compute 2.0 or newer GPUs, but the performance on older GPUs can be worse, also don’t forget that you can run Ethminer in OpenCL mode as well on Nvidia-based video cards and not only on AMD if you are having trouble with the CUDA support or the hashrate you get is lower as compared to OpenCL.

So what kind of performance increase are we looking at here? I didn’t seem much of a difference with the last version posted. Thanks.

I am having more trouble with this one than I have in a long time. Can’t seem to get 2 GPUs to work smoothly running cuda. One just chills there. Does anyone know the proper command for 2 and an example line for reference? Thanks!

This update might be able to provide a bit higher and more stable hashrate, but not that much.
For running with two video cards you need to add
--cuda-devices 0 1to the command line.Ferdjones

I’m getting a problem when I either submit a solution or when there is a new block. All of this happens on ethereumpool.net (I don’t use the others), and it happens when I use the cpu mining (when I’m using the computer, 4 of 8 threads), or when I use the cuda mining.

I’m not sure if this is a pool problem (notice the extra hash sigs), or if it’s this version of the miner. I have tried all of the cuda-schedule options, and get the same results, after new block or submission (failure I’m guessing), it goes to 0 hashes/sec.
Anyone know if it’s me or the miner or the site, and what if anything I can do about it? TIA

You name of miners set has a problem, your name miners should be 2 or other letters or Numbers at the beginning
remember
September 10th, 2015 at 20:44
You should use mine pool is miners name must be numeric, and must be greater than or equal to 1

If you compile with CUDA 6.5, you will *NOT* get the added performance that is built into it for Maxwell. With CUDA 7.5, you can expect up to 5% added performance on GTX750Ti.

hi, genoil, i am using 750ti to mining, please teach me how to using ethminer to mining, it’s is show something worry over here.

at the same time, the 750ti driver will be losting and miner will system halted in the process，i need restart again. i don know what happen,
