I have tried everything, 100 different launch configs and overclocking all the way from 925 to 1200 core clock and 1375 memory clock to 1800 but i can't get over 580kh/s.

cgminer and reaper, it doesn't make a difference. SDK 2.8 with drivers 13.3 beta 3, 13.4 and 13.5 beta 2 drivers. Nothing seems to make much of a difference.

I use drivers 13.1 and I am getting 650 kh/s no problem. It seems like it is a driver problem, if you are overclocking so high you should be getting higher speeds.

Got this card today too. The funny part is that cgminer is showing me around 500 Khs the pool shows around 600...

You are experience variance. Although your card is actually mining at 500khs, the pool perceives you as mining at 600 because for a certain duration of time you are solving shares a little more quickly. It all evens out though, there will be some times when you are only mining at 400khs on the pool.

Thanks for your answer. Is it possible to post your cgminer configuration ? The settings you are starting cgminer with? Thanks

I would love 650kh/s. Any chance you can share the config and any overclock ?

I've also read about bios flashing to the gigabyte bios which i may attempt later today.
