Hello I have a rig with 3x 7970, Gigabyte GV-R7970C-3GD...

I have tried everything on the internet to get these cards working at 650+, actually they won't mine above 580 kh/s...
I have noticed a strange thing running settings that people over here post... I would usually get more kh/s if I remove the -g 2 !
Which people say is needed for speeds over 700 kh/s.. I have Catalyst 13.4, latest App SDK 2.8.

Quite annoying thing, I have spent more than 10 hours trying to set it up but no progress so far !

Currently running at 550 kh/s using stock settings at -I 13

Try engine at 1080 and memory at 1500.

thread-concurrency at 8192
lookup-gap at 2

and (very important):

gpu-threads at 2.

if by gpu threads you mean -g 2 ! I have the cards running at these settings getting 400 kh/s
