not really sure if it's even possible to get more without overclocking
note: thread concurrency doesn't do anything with skein, it uses the same .bin file no matter what TC you specify because skein doesn't use a thread concurrency
something i don't understand
r9 290 does only 227mh ? it should do more than 280mh right? if a r9 290 is = 2x r9 270
my msi 270 does 144 at stock speed
and also my 380 does 186 mh (210mh @1100) , so i don't understand how is possible to have only 230mhz on r9 290
or maybe with some oc you get close to 300 or not? but i doubt i think must be around 260 (if the 280 does +24mh)
because i m looking for a msi r9 390 speed on skein, can't find nothing even for 290 no much info

now i have one there is the speed of 390
