I'm confused. I thought this card was supposed to get around 300? Can someone help? I'm running at 815 CORE 900 MEM, with Phoenix guiminer, -k phatk DEVICE=0 VECTORS BFI_INT WORKSIZE=256 AGGRESSION=13  FASTLOOP=false.

Anyone have any input?

Thanks!

OC to 1000 then you'll get ~300mh/s.

You don't need to, it goes up to 1000 officially. Something must be wrong.

I use GUIMiner with my 5830....

STOCK GPU (840) / STOCK MEMORY (1125)

OpenCL NONDEDICATED..I get 199 Mhash/s
Phoenix DEDICATED........I get 235 Mhash/s

-----------------------------------------
OVERCLOCKED GPU (900) / UNDERCLOCKED MEMORY (900)

Using the following flags:
Quote
-k phatk DEVICE=0 VECTORS BFI_INT WORKSIZE=256 AGGRESSION=13  FASTLOOP=false

Phoenix DEDICATED.......I get 280 Mhash/s

I tried MSI Afterburner - it was good, allowed me to overclock and underclock etc - but also caused some blue screens. Also after using it, I noticed the GPU/Memory figures in the ATI CCC didn't match what was showing in Afterburner. So I switched back to just using ATI CCC - I may lose a few Mhash/s but the PC doesn't crash and the temps are slightly lower.
