Thanks, i have a strange feeling... With your miner, i get 12Mh/s with all pool on groestl. I have 2 270x.

But with the grs-sgminer i get 7-8 with all other pool than cryptohunger and 30Mh/s with cryptohunger ... same configuration. There is something inside the code of the grs-sgminer make by cryptohunger that can give some strange hashrate ? ...

I don't know but now i'm switching on qubit, earning is the same i think.
