Well I followed the instructions as posted and it seems to be working although I'm somewhat surprised with the benchmark results.
Computed 2995.98 PMKs/s total.
#1: 'CAL++ Device #1 'ATI'': 2868.2 PMKs/s (RTT 2.9)
#2: 'CPU-Core (SSE2)': 311.5 PMKs/s (RTT 3.0)
This card is a Radeon HD 5450 so somewhat a lower performance card but still?
Also the benchmark doesn't show details of the card so perhaps I've missed something.
The proc is an AMD Althon X2 6400 1MB L2 Cache
Can anyone offer some advice on 1) are the results typical and 2) why does the benchmark not identify the HD5450
