    I7 920 @ 4.75GHz on air

    Heya guys,

    My pride and joy:


    System Specs:

    I7 920 D0 (49B)
    DOMINATOR GT 1866
    eVGA Classified x58, bios ver 61D
    Noctua 1366 SE <---- IMHO the best air cooler
    and lotsa TLC.



    ----------

    any input?
    I plan to go 4.8 when winter comes and room temp. will be around -15C
    Tips?

    +2 on that Bobby.

    Dropping HT and going single channel will open up a bit of thermal headroom instantly.

    Nice clocks but that looks like a pretty old version of CPU-Z.....

    What are your temps on that crazy clock speed?

    Sure!
    I have always used Arctic Silver 5. *always*.
    Once you use it.. you can never go to anything else

    That's the eLeet (EVGA's version of CPU-Z) version 1.06.3

    Temps (idle of course..) for this clock are 45-50C.
    Out of curiosity I did try to run SPi1M but never made it past the 5th/6th loop..

    Well,
    under similar conditions (but lower clocks & Voltage) I run SPi1M:

    I know and have a "gut feeling" the system can do better. maybe even go close to 8.0s


    --

    The 4.75GHz is for records (personal), with no intentions of benchmarking.
    In the following days I'll try to go higher and will update here.

    *edit

    Oh, I see. Still, to even boot at those clocks on air is amazing! Great chip you got there for sure.
