    You need to reduce the memory multiplier to overclock at all.

    just for reference for the other guys here... you have a new board but I know they will be interested..

    symptoms.. will post one time in a lot of attempts, or after being left for an hour.. seems to post but no graphics.. starts but locks solid after managing to get to a desktop.. bad caps!! http://www.badcaps.net/

    Bad caps is well known around aD, and is a common suggestion to people with older PCs that are faulty.

    You might need to overvolt your CPU a LITTLE bit. Why don't you post a screen cap to show us what your settings are like?

    I know I need to adjust some memories settings but, I am not sure what to adjust or what all the settings mean. Here's what's in my bios under memory settings.

    Performance enhance....................[ turbo]
    MCH frequency latch....................[ auto]
    system memory multiplier SPD.....3.3 3C (not sure what the setting is but, I changed it after doing some google searching)

    system frequency............800........900
    DRAM timing selectable......SPD manual

    keep in mind that mem tuning should done manually: (havent had too much luck with xmp) find the latency specs (6-6-6-23 or something) your sticks run at the speeds you are capable of doing (1333, 1600, etc) write them down.
    write down also the voltage at those speeds.

    for overclocking there are three main things to focus on (videocard speed notwithstanding) FSB, Mem, and CPU.

    try lowering the multiplier of the cpu to lowest available ( maybe 6?)
    lower the mem to lowest speed as well. then gradually (meaning 5-10 MHz) increase the fsb, rebooting after each attempt making sure the windows desktop completely loads. if it fails loading in this case i would think your fsb voltage is a little low, but unless you got a fan on the northbridge chipset, i wouldnt do it by more than one increment at all, a little goes a long way for voltages, generally.(cooling is super important dude) once youve increased the fsb to where you had it before, (333? 400? tell us your multiplier and fsb clock at stock and what also your trying to reach)
    increase the multiplier in .5 step increments, also saving BIOS and rebooting to windows desktop. once it fails, if you get syntax on your screen (blue error screen) you probably do not have adequate voltage going to your cpu chip. increase by 1 increment and try again. also, that cooler should do what you need no problem:) if you have to raise it by more than 2 you should stop and re-evaluate. (also, look at your cpu box or on manufacturer's website for the max voltage your chip can run and do what you can to keep it under that max value) sometimes at higher clocks (FSB) you cannot attain full multiplier goodness on your cpu chip, so dont be surprised if it only boots at 8.5 instead of 9 or 10/10.5 instead of 11. once you have the chip to adequate overclock, try increasing the divider of the memory back to normal speeds (again, incrementally), and also entering the latency and voltage recommended for that speed/type of stick. occtpt overclocking utility is a good quick n' dirty way to make sure youre chip is performing right (it will quack at you if it fails within the time you told it to work)also, dont rely on(turn off, at least for now) the 'turbo' enhancement for your mem. generally this is a manual affair and *cheats* provided on the board may bring up the voltages too high. also, reboots at the beginning of loading windows can be memory that isnt spec.d right.
    i guess that sums up most of my knowledge. practice and you will get it right
