5830 only getting 215 mhash OC'd

Did not know that Trixx was the official Sapphire program, will try that.

I'm running ubuntu 11.04 so I'd have to use wine with those utilities and i'm not sure if I want to trust wine with overclocking.

But how are you guys getting such low memory clocks? I can't go below 600mhz on my sapphire without it crashing and displaying stripes on the screen.

975/340 gives me 303mhash/s works on both xfx and sapphire
using msi afterburner..

I'm also using ubuntu 11.04, and similarly I can't significantly downclock the memory on my sapphire 5830's without either having the cards crash, or reducing the hash rate to ~150mhash/s per card. For reference, using hashkill-gpu I get around 260 mhash/s per card running at 900mem, 830 gpu. I'm going to try out some of the other utilities today.
