Weird, my fastest worker (3 GTX 780Ti ~ 540 MHash) gets just 80% accepted shares on max.netcodepool.org, but the other two workers (300 MHash and 178 MHash) get 96% and 98% accepted. As if faster workers have more trouble with the pool. Unusual.
Christian.
That's kind of what I've been seeing. My GTX 780's normally get 160 mh/s while the 780 Ti get 260 Mh/s. The 780's get about 75% acceptance rate while the Ti gets closer to 50% - 60%.
I've clocked them down almost to their default superclock boost speeds to see if indeed I'm getting better acceptance rates. I think it has to do with Cudaminer and it's implementation with these GK110 cards. 25% to 50% reject rates are awfully high
