    Well first of all with 4gb you are going to need to make some changes in your timings with your ram.

    What is your full settings? I will be gone here in a second, but please post your full settings and I will suggest better to you tonight when I get back.

    The easiest way to find your voltage needed is to start with 1.45 CPU if you are not already that high and then work backwards until it isnt stable. For 3.6 you may need more then 1.45 and then you would for sure need better cooling, what are you using now for cooling?

    My E6400 goes 2.8 G fine @ 1.35 volts.
    Take care,

    Default Re: ga-ep35-ds3r & crucial memory

    If you are having BSOD issues, go in control panel then system (Or right click your My computer and choose properties). Then the advanced tab as shown here >>>



    Click Startup and Recovery and uncheck automatically restart as shown here >>>



    This way you can cause the BSOD again and give me the code it tells you. To fast normally to see because it restarts. You will want to turn this back on later if you want. But giving me the code can help as well, because incase it isnt your memory settings or voltages the code will tell

    I will be back later tonight if you are not around, please post your FULL MIT page settings so I can see what you need or have wrong

    Well orthos fails because of ram or CPU, so you need to test your RAM with Memtest86+ for a while first to be sure that is not the issue >>>
    Memtest86+ - Advanced Memory Diagnostic Tool

    I let the main test ( The first test it runs run fully thru ) then hit C and choose test I then choose test #2 for about a half hour, then choose test again and choose #5 for about a hour.

    That would be this order to choose a test # >>>
    1. First press C

    2. then 1

    3. then 3

    4. and finally select the test that you want to run

    5. press Enter

    6. and then 0 to get it running
