Boinc benchmark do not show real value: since there is point where memory become to slow for transfer data, and calculation become slower. Try yourself different combination , but current one 12 workunit per cycle is definitely the worst choice you can make. Same will be with 6 workunit per cycle. Try 2 cores per workunit ( with HT off , of-course)
