Marvellous, getting 1800h/s with my r9 290 cards! 29% increase!

The memclock on the cards were jumping between 100 (idle) and 1500MHz batshit crazy on 2.2 but seems a lot more stable now.

For those who wonder:

3x r9 290 gigabyte reference with elpida
8gb ram
have not manually set anything (virtual memory nor gpu alloc)
catalyst 13.12
win7 64


The only thing I really lack is temp and fan control, --auto-fan on c/sgminer is just too awesome with my rig being outside with shifting ambient temperature.
