I've got it working now, with CUDA I get 100-110mhash/s on a 670GTX FTW(Overclocked), with an i7 CPU
Using OpenCL I get approximately the same range, but even as high as 120-130mhash/s sometimes.
Not expecting to become a bitcoin millionaire with a 670GTX lol, just doing this for fun. However whatever improvements got added do not appear to be assisting with my machine.
Curious though what is the difference between the bitcoinminercuda.20/30 files? I am wondering if there is something I need to compile myself here.
Topic: NVIDIA Kepler (K20) from 134MHash/s to 330MHash/s with CUDA - page 8. (Read 73331 times)
Nice work. the 20 file got it going and look at the results, 19Ghash from Nvidia cards! 
(30 file returned 209 error)

It's working but BTC is showing work as dupes. Not surprisingly...
GUIMiner ends up reporting as having connection issues fwiw.

Heading out the door now, but will make the changes when I get back. Thanks!
I am getting a 200 error. I didn't see it covered above. I downloaded all the files in the bin folder into the same folder, is that correct?
@InqBit What cards do you have?
I have a GTX480 and GTS450
edit: Fermi cards, but figured it would run. Maybe not?
I edited my last post, try the 20 ptx file. I think psychocoder is working on more optimisations.

Save your bitcoinminercuda.ptx and rename bitcoinminercuda.30.ptx to bitcoinminercuda.ptx and try again. Also, try bitcoinminercuda.20.ptx.
Nvcc : fatal error : Cannot find compiler 'cl.exe' in PATH
Means that it can't find the C compiler. You need to have the Microsoft C compiler installed (e.g. Visual Studio 10 or Visual Studio 10 Express) to be able to build the cuda files. If you do have it already, you just need to run "C:\Program Files (x86)\Microsoft Visual Studio 10.0\VC\bin\vcvars32.bat" first in the command window to set up the paths.
If you don't have it, either download and install the Express version or just copy down the the prebuilt .ptx files from the bin directory in https://github.com/cdmackie/rpcminer-mod/tree/kepler/bin. There are now different ones, so try the bitcoinminercuda.ptx first. If that works, rename bitcoinminercuda.20.ptx to bitcoinminercuda.ptx and try again. Likewise with bitcoinminercuda.30.ptx. USe the last one that worked.

That's OpenCl, not cuda, in case you are running the wrong one. Otherwise can you check you have copied the bitcoinmineropencl.cl from the src\opencl directory into where you are trying to run the exe.

About the same hashrate on aggression=10 as guiminer on a GTX 650 Ti, 50-ish MH/s.
I'm not too familiar with the other settings (gpugrid and gputhreads) so I'm not sure if those would raise the hash rate a significant amount,

I can't say, but psychocoder may well know better settings for you. Try info from his first post in this thread.

I'd like a compiled binary for the 209 error, I tried doing it on VS2012 and got a bunch of errors.
Grab https://github.com/cdmackie/rpcminer-mod/blob/kepler/bin/bitcoinminercuda.20.ptx and rename it removing the ".20", replacing the other ptx file. Let me know how you get on.

@charliemaggot: Thanks for building Win version.
Anytime. I just compiled it. Kudos for your coding it.
So for 209 errors, change buildcuda.bat
-gencode=arch=compute_35,code=\"sm_35,compute_35\"
to
-gencode=arch=compute_20,code=\"sm_20,compute_20\"
and run it. If you don't have VS2010, I can build it and throw it up.
For GTX690 you must compile with sm_20. I work on a version which shuld be run better on Fermi GPUs and I have get the register count down from 63 to 34 but without any speedup :-(.
