download sapphire trixx. underclock memory to 300 and start working your way up on the core clock.. start at 900.. if it crashes drop 15 if not go up 15 more. i have a dew of these cards.. one is stable at 985 the other 1015 maybe even more i havnt pushed it farther. windows guiminer -v -w256 -f1 sould get you in 300 Mhash ballpark, -f1 will make your desktop lag a little so i turn that off if i need from time to time(remove setting stop miner and restart)

OK, so this was super helpful. thx

I ended up using your flag, setting the memory to 300, and pushing the clock up till it crashed at 960. I then backed it off to 950 and it ran for a while at about 275-285 Mhashes (fluctuating wildly). This stopped the miner after about an hour, so I backed off the clock to 945. It is now getting now bouncing from 280 to 283 Mhashes.
Is this good? Should I tweak about the memory up or down some?

thx
