I actually managed to get 64 version to work with my ASUS EAH 3450 256MB.
1.1 Mhash is the neat result, ill post pictures later.
Wait, wait. I don't think you're mining with your GPU there. What's your CPU usage? What's the miner? If you have AMD-APP installed, it'll emulate GPU-processing using the CPU if you don't select the right device...
Did you read the 1st post?
As a result, my video card (Mobility Radeon HD 3410) crunches through fewer hashes than my CPU (AMD Turion Neo X2 L625). If I didn't mangle poclbm too badly, it estimates that it crunches at a rate of roughly 0.850 MH/s.
