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.

I don't know if this helps: http://myriad.theblockexplorer.com/help.php

12Mh/s seems normal with my config, but the hashrate with grs-sgminer on cryptohunger is crazy (2.5x than expected) and the hashrate with grs-sgminer(almost 2x less than expected) on other pool is very very low... so i think there is something wrong inside the grs-sgminer and cryptohunger...

grs-sgminer for cryptohunger has optimized kernel for groestl algo but it is closed source and the miner/pool has a fee for the optimization

i know there is a fee and i still mine at cryptohunger because i get more coins from mining there than other pools despite the fee, so the optimization is effective

but i did not expect the fee to be so high at 20%
i can confirm the fee is 20% by looking at the sender payout address which is D96y4y74NUegfYJ8yn9chxbPLrRiypCF6V

http://insight.dgb.cryptopoolmining.com/address/D96y4y74NUegfYJ8yn9chxbPLrRiypCF6V
- notice newly generated coins, 7647, are sent to two addresses
  > address 1 D96y4y74NUegfYJ8yn9chxbPLrRiypCF6V (payout address) = 6117 or 80% of 7647
  > address 2 DBy3212dWAPPzPcyt5fSSchjyozyr5ejLw (pool fee address) = 1529 or 20% of 7647

http://insight.dgb.cryptopoolmining.com/address/DBy3212dWAPPzPcyt5fSSchjyozyr5ejLw
- notice pool fee address has total received coins of 2463903 DGB
- cryptohunger site has total confirmed blocks 1440
  > 1440 blocks * 7647 DGB per block * 20% fee = 2,202,336 which is close with block explorer total received since earlier blocks had more DGB

despite the 20% fee though im still getting more coins from the optimized kernel
- other sgminer groestl my hash is 10.1 Mh/s
- on grs-sgminer "displayed" hash is 13.1 Mh/s or an increase of 29.7%, so that is 29.7% more coins on cryptohunger
- notice i use the word "displayed hash" because grs-sgminer already factors in the 20% fee on the hash display
- so I assume my real hash using grs-sgminer is 16.375 Mh/s but only displays 80% (13.1 Mh/s)
- this is important so that when you use displayed hashrate on mining calculators you get the proper approximation of coins to mine at a given difficulty

hope this helps

i have 300% of increase with grs-miner (10 -> 30Mh/s), something is not normal even if it's optimized. I don't read there is a fee and how high was the fee. I don't like hidden things.
I'm not of this pool now.

this is a problem when using an not so used hashing algo, someone can fuck it up easily in a simple way : optimized private miner only working on his own pool.

since nobody will release a fair opensource miner,
a good solution would be to switch groeslt to another algo or simply remove it.
