Some help for newbies. Use this miner to get the best hashrate but I think this one is also integrated with the wallet.
https://bitcointalk.org/index.php?topic=652849.0My results:
R280X -> 12,74 Mh
R290 -> 15,72 Mh
sgminer -k groestlcoin --difficulty-multiplier 0.00390625 -o stratum+tcp://maya.aidbit.net:3032 -u YourWalletAddress -p x -I 22,22,22 -g 1,1,1 --gpu-engine 1200,1200,1100 --gpu-memclock 1050,1050,1000 --gpu-fan 65 -w 256,256,256
Drivers: AMD Catalyst 14.7
I'm pretty sure higher hashrate can be achieved but I was not able to run faster. If anyone is getting better results, feel free to disclose details of your setup.
Thank You Sir very much for this post!
