Those are low numbers. My 6850 can pull 262 kh/s at intensity 17, and my 5770 can pull 207 kh/s at intensity 18.

First gpu is 6850, 2nd is 5770:

Code:

--worksize 128,256 --gpu-engine 900,885 --gpu-memclock 500,1235 --shaders 960,800 -g 1 --intensity 13,17

Yes both my cards have a core overclock, 5770 likes small overclocks, but 50mhz+ on both core and memory drops hashrate (?).

And yes on my 6850 I am downclocking the memory to 500, it doesn't change my hashrate. AT ALL.

Thanks Tittiez for sharing that. I cant get over 158kh/s even using your same command line options on my 5770. I guess until the voodoo gets worked out of this I can live with the hash rate on this and my 6970 being 158/306 kh/s.

I tried these settings and a couple others and still can't get it over ~145 kh/s. I am wondering if this is being caused by my using a x1-x16 riser cable on the 5770. I am going to switch things around and see if that makes a difference.
