    I can't get the computer to boot with 8GB trying the above
    This is what I have running 4GB from CPU-Z

    CPU-Z Validator 3.1

    These are the configuration settings the builder sent me
    (some of the settings are not in the MIT)

    This pretty much sums it up:
    You can also flash the board to the latest BIOS
    if you haven't done so already. Otherwise it's just
    the board not driving this RAM properly where all its slots are populated.

    Are you on the latest BIOS? If not be sure to update in case it's a BIOS issue.

    Yes, 1.5 MCH is way too much, and you can't even enter settings like that anyway. +0.2-0.35V should be plenty for 8GB

    It could just be X38 doesn't like 8GB, or this memory model in particular. You could also try 566-18 as suggested above, or 666-18 and see if that helps. Set static tRead Value to 9-10 for now too as that might help too.

    If all else fails, set 2.00B for 800MHz memory speed as I mentioned, that should run no problem unless the board just wont handle 8GB

    Thanks for this. I will try again tomorrow.
    The thing is this motherboard has been running Ok with the 8GB of memory. For some reason when I change the hard disk to a new 1TB I wasn't able to boot, so I remove 2 memory sticks and it booted. But when I put the 2 memory sticks back in the compuetr doesnt boot. I don't know what the previous BIOS settings where.

    Ahh ok! So this new disk, is this storage or do you have windows installed on it?

    If windows is installed you may need to be sure you have the correct SATA settings, not overclock settings.

    From you mobo user manual:

    The Functions of the F11 and F12 keys (For the Main Menu Only)
    F11: Save CMOS to BIOS
    This function allows you to save the current BIOS settings to a profile. You can create up to 8
    profiles (Profile 1-8) and name each profile. First enter the profile name (to erase the default profile
    name, use the SPACE key) and then press <Enter> to complete.

    F12: Load CMOS from BIOS
    If your system becomes unstable and you have loaded the BIOS default settings, you can use this
    function to load the BIOS settings from a profile created before, without the hassles of reconfiguring
    the BIOS settings. First select the profile you wish to load, then press <Enter> to complete.


    You can overwrite a bios name and/or save a different bios profile by using F11.
    I frequently have one or more "test" bios profiles saved while I'm testing my bios settings for stability.

    Do you still have CPU Vcore set to 1.35 volts?
    This seems awfully high with your cpu running at stock settings.

    If you post a picture of the CoreTemp window, this will show us what the standard voltage is for your cpu.

    What app do I use to get the core temp from?

    The new disk is used for additional storage.

    How would the SATA settings affect memory. Do you use SATA drivers??

    Can you boot with only the two sticks you took out when you installed the HD?
