When i'm choose Keccak
Keccak isn't one of the supported algorithms in 3.0. It's only there because CoinWarz returns it. I'll check into this and make sure it's no longer visible in the UI.
I looked in my sphsgminer/kernel folder in multiminer and i was surprised to see a "keccak.cl" kernel there. I didn't tried it because of the error to chose a keccak miner in multiminer but maybe we can already mine keccak with sphsgminer. May worth a look into this...
