Thank you.
That's work a treat. Now just need to try and increase the 5850 to above 250kh/s may have to play with core MHz and see if anything's been messed with it.
Looking at CPU z it looks like the 5850 is using hardly any ram compared to my 6850
I thought scrypt was memory intensive
5850 should be running at least 350khash/s
I got the same card and running with these parameters: thread_concurrency 5824 -I 19 -worksize 256, and I'm getting 400khash/s (overclocked)
