Today I put my mining rig back in action. Had stopped 4 years ago because the housing agency came by with the police because they where thinking that it was a cannabis plant .

I use the  SAPPHIRE R9 290 Tri-X 4GB card. I'd remember I had 800-900 Mh's speed per card. Today, with a fresh install I downloaded Claymores miner and try to mine PIRL.
My speed now is only 28Mh's.
Is this because of a different script, or am I missing something.

Hope you can help me
