Okay, it's a mystery, what's going on with my hardware, or it's a programme fault? Now my good old 7870 shows only ~20 kh/s and it was 170 kh/s yesterday. I use -I 12 -g 2 -w 256 --thread-concurrency 4096 and thats was perfect for mining in addition to my 7970x2. Any thoughts, por favor? :3  

upd Awkey, nevermind, accidentally, it works now. Freaky windows, if not this stupid gaems which i am addicted to 3;
