    Suprisingly new motherboard didn't help with overclock

    Just upgraded by P5B (P965) to P5E (X38), hoping for more overclocking. I managed to get to 3.4Ghz with the old board, and the new board wouldn't even do Prime95 stable at 3.45.

    There may be more settings on the P5E but it didn't help with overclocking at all.
    I've checked out a lot of guides for P5E tuning which proved to be very useless. Ended up having to keep most of the stuff at auto, otherwise the system is not stable.

    If it wasn't the dual USB controllers on the newer ICH9 I would just go back to my old board (use less power).

    I wondering if there is any point to buy high-end motherboards if it doesn't give you more Mhz.
    Or pehaps someone would offer some decent setting for this particular board

    Re: Suprisingly new motherboard didn't help with overclock

    If you migrate from a good board, to a marginally better board, then you're likely to get no more than marginally more out of it. Did you really expect much more from that chip? Waste of money really.

    Do you know what's limiting your OC? Is it the CPU, the FSB or the memory?

    Re: Suprisingly new motherboard didn't help with overclock

    It used to be memory-limiting with the stupid Trfc limit of 42 on the P5B.

    Apparently it have now moved to CPU limit. Gave it extra 0.05V Vcore and it wouldn't even budge another 100Mhz. Memtest86+ went fine with 3.6Ghz at tightened timing but would self-reboot doing Prime95 blend. It wouldn't even give me rounding error and just reboot straight away at 3.45Ghz+ so I can't determine where is the problem.

    Will try if swapping ram slot help or not.

    Worse case I'll just grab another Q6/8/9xxx to use on my old board.
