    There's nothing wrong with the E7600, especially when you can OC to 3.4GHz on stock vcore.
    It would be a waste of money to invest in new CPU just to find out you must update BIOS after all.

    Updating BIOS may be all you need, you can pull one stick of ram for the update too if you are too worried.
    Flashing with the built in Q-Flash is quite safe. I have flashed my P43 board several times, and this board twice.

    I definitely agree, you should update to the latest BIOS no matter what CPU you have or plan to get.

    Use Qflash and you will be fine, it's very simple and quick

    i lent a q9400 from my friend to make some tests on my board and the stock results are not good


    ---/
    i think core0 is too much hot on load, or this is normal for core0 ?

    here, a simple test on stock

    can i overclock with core0 getting 66 on load ?
    i want to try 400x7 or 8, the stock is 333x8 and this cpu dont have fine ratio (+x.05)

    Are you using the Q9400's heatsink or the E7600's?
    The built in DTS are not very accurate and error may vary from -10c to +5c.
    What kind of load was it for those temps?

    i'm using q9400 heatsink i saw is different from e7600
    q9400 heatsink have a circle of cooper
    e7600 heatink have a square of aluminium i think
    i used prime95 for a couple minutes

    edit. 333x8 (stock) i dont get issues with ep45 but with e7600 333 or 400 give that issues wich you already know

    Yes those temps are a bit too high for stock with Prime95.
    What thermal paste do you use?

    Temps also depend on the ambiant temperature.
    As I said the sensor are not very accurate, it may be just that that cause the difference.

    At 23c ambiant I get 31c idle and 47c Prome95 (small FFT 24K) with stock settings.
    You need a better cooler if you want to OC.

    on core2duo core0 and core1 = 41 idle, seems to be an issue only core0 be +5 and core3 is -10, core0 looks increase fast
    ...about the o.c, i never had a stable o.c, i though, but never hads, when the system restart turn off and on again, entering on bio, there's a red warning, the problem is really with the memory multiplier, update bios dont solve the problem, i found on google the same issue happening with F9 version

    the same issue happened with q9400 @ 400x, on e7600 (400x.8.5), everything looks fine on games, but i got a BSOD when i was converting a video file, games dont use 100% or 80% of cpu all time, but video conversor uses, my prime test was always couple minutes (my mistake)

    so, the only over i can do with this board is increasing fsb with memory and never use multiplier

    e7600 (300x11.5) memory ram @ 900mhz is perfect but is nothing compared to (400x8.5)
    q9400 (375x8) memory ram @ 900mhz is perfect too, but this overclock on memory gives a lot of latency even if a decrease -3 on spd

    memory @ 800mhz with 6 spd give more read then memory @ 900mhz with 13 or 10 spd

    left stock, right o.c on memory
    x

    what is better ? stock or o.c ? @900mhz is harmful for memory ? any benefit ?

    No 900 is not harmful to the memory, hi voltage, or hi temperatures may be harmful.
    OC Read and latency results are worse than stocl, you need to set tRD(Static tRead Value) manually, try 8-7.
    400x8.5 is not a problem for the E7600, 400x9 should be easy too, but when OCing you must be persistant and patient.
    If 375MHz FSB is easier for you to tweak you can OC with mulriplier to 3.75GHz or 3.93GHz, but you will need an aftermarket cooler for it.
