    Overclocking Q9550 E0 with p5q deluxe

    Hello, I have just purchased a new machine that I would use up ..

    Here is the rig that I bought:
    CPU Q9550 E0
    MB P5Q Deluxe
    RAM OCZ reaper htc edition 2x2GB PC8500 5/5/5/15
    CG 275 GTX Gainward Golden Sample
    HDD1 WD Caviar Black 500GB
    HDD2 WD Caviar Black 500GB
    Alim Corsair TX 650W
    A recorder to the con ( sony)
    Xigmatek box midgard
    CPU cooling Noctua NHU12

    Here is my goal : would like to go with the 4Ghz with reasonable temperatures and pressures which it can handle ...Well see if my cpu can hold it ?
    I know a few bases of the OC but I'm far from a pro! hence approaching for help today ...


    For the moment I'm doing a test on CPU Stress MT RC2
    ratio: 8.5
    FSB: 400
    PCIEx: 100
    strap: 333
    ram: 1 / 1
    Vcore: 1.225
    cpu gtl: x0.630
    cpu gtl x0.670
    CPU PLL: 1.50
    V fsb: 1.20
    dram: 2.2
    V NB: 1.10
    NB GTL: 0.63
    V SB: 1.1
    sata PCIEx: 1.5

    On my P5Q deluxe my PC 8500 has unflinchingly up to 570 may be the relaxation of the tRFC. For the rest, did you try to release the perf level (met the test for a 13 rise in the FSB, it plays a lot on the perf it must then fall back) ,the voltage ranges that you have tried seem correct And also puts the strap 333 with ram in sync, With 2 point (if you did not already) mounted in a retry frequency. Impossible Oc Strap with 400 of my own, whatever the bios. I stabilized at 8 to 450 FSB on a quad

    Common Performance Level

    CPU Voltage: 1.20
    CPU GTL Voltage Reference (0 / 2): 0.63 (major questions)
    CPU GTL Voltage Reference (1 / 3): 0.68 (major questions)
    CPU PLL Voltage: 1.50
    FSB Termination Voltage: 1.30
    DRAM Voltage: 2.3V
    NB Voltage: 1.40v (directly below the crash is under stress Cpu Mt)

    ratio: 8.5
    FSB: 459
    PCIEx: 100
    strap: 333
    ram: 1 / 1
    Vcore: 1.2625
    cpu gtl: x0.630
    cpu gtl x0.670
    CPU PLL: 1.54
    V fsb: 1.34
    dram: 2.2
    V NB: 1.34
    NB GTL: 0.63
    SB: 1.20
    sata PCIEx: 1.5

    3901Mhz is stable for 30 min temp: 46 - 68 ° C
    Now try 1:00

    ratio: 8.5
    FSB: 465
    PCIEx: 100
    strap: 333
    ram: 1 / 1
    Vcore: 1.275
    cpu gtl: x0.630
    cpu gtl x0.670
    CPU PLL: 1.54
    V fsb: 1.36
    dram: 2.2
    V NB: 1.36
    NB GTL: 0.63
    SB: 1.20
    sata PCIEx: 1.5

    With 3955Mhz the problem is temperature , that is after 18minutes!
