we just like doubled its difficulty almost
what cards you runin?

I only got 220Mh/s
wow my 280x runs 230 on skien lol....
if I go over a certain amount the power company charges me $0.35/kilowatt hour
my .bin file is named skeinHawaiigv1w256l4, and I am running it with I -14
anything I could do to boost my skein mining?
Memclock as it was said is not necessary. I helped with configuring a 290s, the result was between 240-260 depending on the card, I can safely say 240mh is a benchmark for 290s. Memclock set it to 1000, use gpu thread 2, and play with the TC ( 16000k , 18000k) , intensity is not needed on skein , maximum i=8, the most important is engine clock, put it as high as you find it stable and reliable depending on how comfortable you are with OC, minimum 1030, try 1050,1080, maybe 1100 if you want to try it out.
My mem clock goes all the way down to 300 according to Msi ab when mining. About tc, wharlt are the usual TC candidates? Mine was 24550 on scrypt, dunno what it wiol be here in skein
