I tired every setting here my best was --thread-concurrency -w 256 -g 2 --lookup-gap 2
Core at 915 Memory at 1600, gets me 640 kh/s... How come you guys have the same card and same settings doesn't work Huh

What is your card's manufacturer?

I have this card

http://www.gigabyte.com/products/product-page.aspx?pid=4102#bios

Even this setting isn't stable !

Do you have a single card?

What happens if you lower the memory to 1500 and increase the core to 1000 or 1050?

Can you paste your cgminer.conf?
