Current testing environment has ATI Radeon HD 5670 Graphics : http://www.amd.com/en-us/products/graphics/desktop/5000/5670
I also have other 3 R7 200 series to mine, but first I want to make it work on this one

Bitcoin, Litecoin, Doge, all are working with this card on GPU so Kryptohash should be okey from my point of view

I have tried the following scenarios :

--shaders 1 --shaders-mul 1
--shaders 400 --shaders-mul 1
--shaders 400 --shaders-mul 7
--shaders 128 --shaders-mul 7

everything seems to output error -54 Enqueueing kernel onto command queue. (clEnqueueNDRangeKernel)

I found that the param -w would solve the problem so right now I tried

-I 16 -g 2 -w 128 --shaders 400 --shaders-mul 7

in this case I get 3.5 Kh/s

for scrypt (litecoing) there is a param : --thread-concurrency , there is something similar here ? or any ideas to get that 3.5 value increased ? or where can I find a list with all accepted params for this version ?

Thanks

For Kryptohash, the thread concurrency is the combination of --shaders and --shaders-mul parameters.

Try something like this:

-w 128 --shaders 448 --shaders-mul 2

Then, increase the shaders-mul value until you find the max Kh/s

Also, try with -w 64 and see if you get better performance.
