    Did you check to see if your system clock was still showing the correct time of day?

    I recall running a bench on an old machine, ages ago. It had a turbo button in it, but the machine design was stupid - the real-time clock update frequency was tied to the CPU frequency. So when you used turbo to make things faster, you couldn't measure the difference using the PC's clock, because it had counted faster as well.

    More commonly, I've run into systems where a chunk of assembly code will disable interrupts while running a critical section; then the system clock loses updates and the benchmark measures much faster completion because very little time passed, according to the clock.

    Yes, clock never changed and system is real stable at those clocks. haven't had any crashes or issues even while playing BF3 for 4 hours today and this game, on the right maps, uses 60-70% CPU usaage..... pretty awesome modern game we have here.

    Here is something till Interlogos shows up for testing. Its a ES Magny-Cours 12 core with unlocked multi. 7 cores are at 3.3gig and the other 5 is at 3.6gig. Best I can do on air cooling and the voltage reg on this G34 motherboard.
