Hmm wondering if anyone had any idea of what was causing this,

I'm running two Sapphire R9 290 and the GPU1 is getting a lot less hashrates than the second...



In other rig i have two R9 280x and i get a diferent hashrate, but aceptable, not like this

edit: ok i found the problem, I guess my mem clock was to high and somehow was messing my hashrate on one gpu... i lowered it and now I'm getting 840 in gpu1 and 940 in gpu2 and will leave it this way for now
