    I have an Asus P-5B Deluxe motherboard with an Intel E6600 Core 2 Duo CPU. Right now I just have everything set to auto and it runs fine. But I want to overclock it a little bit. When I go in to the Bios under RAM speed I have it set on DDR2-800 because I have DDR2-800 RAM. If I turn up the FSB speed do I need to turn the RAM speed down to DDR2-667? Or does the Bios automatically change the FSB-RAM ratio? I've read the manual cover to cover but its not very clear on this subject. Thanks for your help.

    it depends on how much you call overclock a little bit are we talking 3ghz or 3.6 ? i would run your ram on a 1:1 ratio with the fsb go up to 400fsb turn up the voltage if you have adiquate cooling if your looking at something like 3ghz then it should be alright on stock voltage and just keep your ram as close as you can to 800mhz if its cheap stuff if its good stuff like ballistics or something on the lines of that then you can overclock them

    i have the same board and have quite a lot of experience overclocking it.

    go into the advanced section of the bios and set these-

    ai tuning=manual
    pci-e=100mhz
    pci clock syncronization=33.33mhz
    spread spectrum=disabled
    memory voltage=depending on your ram i'd start at 2.0v
    cpu vcore voltage=1.35v,is a good place to start
    fsb terination voltage=1.200v
    nb vcore=1.25v
    sb vcore-1.5v

    i always set the last 3 voltages on the lowest setting,not on auto.

    next go into advanced chipset config and into north bridge config

    set configure dram timing by spd to disabled.

    go back into advanced menu and onto fsb frequency,you will see it starts at 266.enter a no. like 280 etc,not too high to start with and save and exit.see if it will boot windows and run stuff.you could try the science mark 2 program to test it.

    if it runs ok,go back into the bios and raise the fsb frequency a little more,and test it again.

    if you get to a point were it fails to post(boot up) or load windows,just turn your pc off,and back on(not a reset) and it will boot up fine,with a message saying overclocking failed and to press F1.

    now just go back into advanced menu and raise the cpu vcore by ONE INCREMENT.ie- frome 1.325 to 1.350.reboot and try again.

    it can be very time consuming.i will help you if i can.

    That's no lie, Tigger helped me with my P5B Deluxe setup, Tigger69 is a P5B master! I'm hitting 500fsb with stock MB voltages, 2.15 mem voltage for DDR1000 memory (set to 1:1, that makes it 533 when my 6300 is at stock (1066/4=266). My 6300 is at 3.5 using 1.4v in bios, reads 1.36 idle, 1.34 load.

    These are easy boards to OC with. If you're want some OC recommendations and preperation ideas, feel free to check out my guide/article (link in sig). Just remember different components OC differently, nothing is exactly the same.
