I do this config:
-lookup-gap 2 --auto-fan --gpu-engine 1025 --gpu-memclock 1500  -w 512 -v 1 -I 20 -g 1 --thread-concurrency 24550 --auto-fan --temp-target 80 --gpu-powertune 20

And I got stable 915KH/s 80C and 3800-4200RPM (68%) Fan speed.

Thanks I will try and share the result.

Thanks man!

So I think I fucked up because there are much cheaper video cards, that get the same hash rate is it?

Hi guys, I am new in mining, from 1 day, and I have 2x MSI R9 290 with cgmining parameters:
lookup-gap 2 --auto-fan --gpu-engine 1000 --gpu-memclock 1500  -w 512 -v 1 -I 20 -g 1      and I can't get hash rate over 800/810Kh/s on each card. Is there anything that I missed in cgmining config or this is the max of these GPU's?
