    I'm pretty sure that the cpu's were throttled when WPrime took the system info. Regardless, it's not a bad result even @ 1.7Ghz and memory @ 670mhz CL9.

    Cinebench score is screwed up. It's only able to utilize 16 cores at a time.
    The stream benchmark would be interesting

    To run it on 24 threads use
    Code:
    set MB_BIND=yes
    set MP_BLIST=0,1,2,3,4,5,6,7,8,9,10,11,12,13,14,15,16,17,18,19,20,21,22,23
    set OMP_NUM_THREADS=24
    start /b /WAIT /HIGH stream5.8_omp-64.exe
    AMD claimed an quad socket istanbul system scores around 42GB/s with probe filter enabled vs ~25GB/s without probe filter at 2.6GHz with 2x dual channel DDR2 800.

    Here's a dual socket comparison
