    1.load and save the optimised defaults and repost then check the bios settings are as they should be..memory timings etc.
    If the machine is booting ok use memset to see what the timings actually are when you are in windows see if they conform to the memory spd sticker.
    ! dont use the save settings in memset or it will lock them into windows.

    Some other brands/types of motherboards have no ram voltage adjustment.
    They need 1.8V ram.However they pump out approx 1.83V in bios to account for voltage drop.
    I would try your ram with a manually set voltage of up to 1.9V.Try 1.84V first and see if there is any improvement.

    Bring the cpu host frequency up to 399 or 401 mhz and try either the 2:00B or 2:00D multiplier .(leave mch latch freq on auto)
    The 2 multipliers are supposed to offer the easisest compatability across the cpu/mch/memory interface.
    nb ive seen people having problems at exactly 400mhz,is why im suggesting 399 or 401.

    Oh set your cpu multiplier to 7 or even 6 for now if you are worried about overclocking.

    These are just things to try and I did read your original post and know you have tried variations of these already.

    If you are using 4GB you should use 1.2-1.24 MCH, and really you should not mix modules. If you are not, you can ignore me :)

    Please post your current full settings in a template, link is in my signature.

    And please do let me know which ram you are using, thanks

    I'm only using 2x1GB = 2GB (matched pair, I'm not mixing modules). Right now I'm trying the KVR800D2N5K2/2G (CAS 5), but earlier I tried the KVR800D2N5K2/2G (CAS 5) and had the same problems.

    I even went so far as to try reducing the Memory Frequency to 667MHz, increasing almost all of the various timings by 40% (i.e. 7-7-7-25, as well as many settings under Advanced Timing Control), and Windows Memory Diagnostics still crashed at exactly the same point -- in the Stride6 test. So I'm not exactly convinced that this is a timing issue.

    I did also experiment raising and lowering the MCH Core, as well as DRAM Voltage, but that didn't seem to help either.

    I'm pretty much convinced that this memory should be able to run at mostly Auto settings since nothing here is exotic (i.e. name-brand memory, listed on Kingston's page for this motherboard, also on the motherboard's supported list, no overclocking, only 2x1GB, etc.). Whatever happened to the days of buying a well-known motherboard, adding well-known RAM and having it work without 20-30 hr of tweaking? :-)

    So far my guess is that the motherboard is defective.

    If it is actually not defective, but if this will require another 10 hr of tweaking/diagnosing to solve, I am really considering returning this motherboard and trying another brand that will work out of the box.

    But before I consider that, let me share my template. It's mostly just from the Optimized Defaults + suggestions from the template. Thanks for your time.

    Ok, I am giving up. I just bought a ASUS P5Q Deluxe and will see if that works. Thanks everyone for all your time and energy.

    To close on this, I got an ASUS motherboard and everything works fine now: Windows Memory Diagnostics passes, memtest86+ passes, Windows 7 installs (I'm using it right now to post this), etc.

    I guess I'll chalk it up to a bad motherboard and will RMA the Gigabyte.

    Thanks again for everyone's help.

    I'm sorry to hear that your motherboard wasn't working. It sounded more and more like something was broken. I wish you luck. np. Thanks for the update

    p45 ud3p 1.6 fb stable but fd fails or is it just my ocz incompatibility?!? This guy has problems uniquely similar to mine. I'm starting to think this ocz brand is just not that great. JR P45 driving me crazy!

    Sorry to hear you had to switch teams! It very well could have been a faulty board, this happens with anything as you know.

    Well good luck with things, at least now you have a working system!
