    Cool program!

    Here's a quick test on my new rig.



    It's core i7 @ 4.0gHz with 1600mHz DDR3 (QPI is only stock , oc'ed for 24/7 use with multiplier since It's a 965.)
    EVGA z68 FTW
    i7 2600k @ 4.8
    8gb DDR3 1600
    3x GTX 580 3gb HydroCopper2
    Silverstone Strider 1500W
    Areca 1880i w/ 6x intel x25m
    On water

    Interesting... Your benchmark is valid (the checksum is good). But the CPU frequency is wrong... And by the very impressive timing, I can tell it really IS at 4GHz.

    I swear there's something wrong with the rdtsc instruction... Because it doesn't detect turbo boost from 3.2 to 3.4 on my friend's computer. (it reports it at 3.2 even with turbo kicked on)

    Maybe I'm not using it right.

    Problem is: I actually don't know how to fix it. Anyone, by any random chance, know how to do this properly?
    Main Machine:
    AMD FX8350 @ stock --- 16 GB DDR3 @ 1333 MHz --- Asus M5A99FX Pro R2.0 --- 2.0 TB Seagate

    Miscellaneous Workstations for Code-Testing:
    Intel Core i7 4770K @ 4.0 GHz --- 32 GB DDR3 @ 1866 MHz --- Asus Z87-Plus --- 1.5 TB (boot) --- 4 x 1 TB + 4 x 2 TB (swap)
