Working great on my 3570k, it's a bit faster that claymore's, few percents (263-->275), and what is best, it has lower fee
if you want to, default is 4% I think, I'm mining at 2% atm.

https://twitter.com/yvg1900can you share your config, i have a 3570k and it dont seem to go higher then 164 at 3 threads... thats on win 7. are you useing linux or windows?
and how do you even adjust the donation amounts......

Shot taken after a day of gaming, light video editing, surfing etc... On fresh boot, everything that consumes resources closed, it climbs to 275H/s.
Can't take a new shot as I'm abroad atm...
And fee editing, I think it can't be completely disabled, but adjusted within 2-XX%, not sure if 2% is a minimum, that is the set amount if one removes the
&donation-interval=50 from the mining params
E: And it is clocked to 4.8, so that might make a make a difference too... (depending of your OC ofc

)
ah that might explain it, mine is all stock as a rock clocks lol.....
i noticed your useing it on windows 8, how did you get it working without the hugepage file error..... i wanna try it on my 4770k and 4900MQ but i cant get it working stable on win 8.1
now at 232 at 4.4ghz. dont wanna push it higher in stock air cooler. much appreciated....
