try with another driver version:

https://bitcointalk.org/index.php?topic=779598.msg8787566#msg8787566

you don't need to install the whole driver, just put the opencl.dll file in the sgminer executable folder and run.

Are u using Linux? I've found some info dating 2014 year saying video drivers under linux(especially 14.6) runs better for groestl.
i've tried 14.6_beta, 14.7_rc3 - no difference at all. also played with .bin .cl files.

btw do u have a hawaii.cl file ? Using groestlcoin.cl gives rejected shares 100% on DiamondCoin
sgminer-5.4.0-nicehash - gives little better +1-1.5Mh/s hashrate

Yes I use linux.
Diamond and groestlcoin use the same kernel.
DiamondCoin is another thing, unrelated to diamond.

Thank you ! Finally i got results that i wanted. Just needed to use groestlcoin.cl in bat file by writing -k groestlcoin. Makes hashrate 15.2 Mh/s for 1100 mhz core and 16.53 Mh/s for 1200 mhz core.

Wait.... all shares are rejected due to low difficulty

did you put memory to the lowest clock possible?
about low difficulty, try adding this:

--difficulty-multiplier 0.0039062500

EDIT: you should use -k diamond and rename groestlcoin.cl to diamond.cl
