    Ok professorJim,

    I have taken on board your suggestions and have been doing some testing.

    With the following settings;

    Code:
    Advanced Timing Control 
    tRRD......................................: 4 [Auto]
    tWTR......................................: 4 [Auto]
    tWR.......................................: 6
    tRFC......................................: 52
    tRTP......................................: 4 [Auto]
    Command Rate (CMD) .......................: 2
    I was able to;


    • Run memtest for 10 hours no errors.
    • Prime95 - Blend test on 2 threads for 12 hours no errors.

    I have yet to re-run the burn test, but will do to ensure that it is also stable.

    So back to my original question, I still cannot cold boot when overclocking. I have had one different startup scenario where it posted successfully then blue screened loading windows. All other startups require Ctrl+Alt+Delete at least once, at most twice, to get it to boot.

    Any ideas?

    Thanks

    howdy, it's me again. hope you don't mind

    Code:
    Static tRead Value...........................: [9]
    tRD Phase0 Adjustment....................: [0-Normal] 
    tRD Phase1 Adjustment....................: [0-Normal] 
    tRD Phase2 Adjustment ...................: [0-Normal] 
    tRD Phase3 Adjustment....................: [0-Normal]
    or this

    Code:
    System Memory Multiplier .................: 2.50A
    the memory will run at 1000Mhz it is not that bat at all, mine runs like this 1000@1.8v since 1066 is a no-go at any voltage.

    You can aslo set

    MCH Core that is too high or too low can cause instability or boot loop problems.

    You're currently at 1.20 volts, try testing with 1.22 - 1.26 and possibly several steps below 1.20, depending on which options are available with your motherboard.

    ************* We have a winner !!! :-) ***********

    My default for MCH Core is 1.10V, and I had read elsewhere on this site that with 2x2GB of 1066 memory you definitely need to run at least 0.1 volts higher on MCH Core, so that is what I had done, running @ 1.20V

    I set it MCHCore to Auto and now my machine posts. I am now stable @ 4.0Ghz and am able to run Stable Intel Burn test etc etc.

    Thanks for the help.

    P.S. Yuu I did try your settings @ 2.50A but with 445 Mhz to get 4.0Ghz it made my memory run too fast (1112.5Mhz) and I could not boot. I had to clear my CMOS. Perhaps (If you only have 2 sticks of Ram), putting your ram in the Second channel might give you a better result. I have no memory issues when running in this channel, and can happily run with the recommended 2.1 volts

    The relevant settings look like

    If you leave Auto upto 449 FSB you get.

    Hi,

    Well I'm back.

    I may have been a bit pre-emptive in my success message.

    I have had successful cold boots on a handful of occasions but I cannot seem to get it to consistently boot.

    I have been trying a few different settings just tweaking CPU Core voltage, MCH Core voltage and DRAM Voltage's with no luck.

    But having been testing this for a while I have just notice a pattern.

    I have 4 Drives in my machine 3 SATA Drives of various capacities, and on the IDE channel I have the DVD-RW Drive and an old 40GB IDE drive.

    When the machine will not boot I have noticed that it fails to detect the devices on the IDE cable successfully.


    It will show
    • IDE 0 Master,
    • IDE 0 Slave; and
    • IDE 1 Master
    for the 3 SATA drives;and
    then the IDE drives which show up as IDE 4 are not detected. It either shows them as empty or repeats the drive information in IDE 0.

    I can Ctrl+Alt+Delete and reboot and it can take 2 or 3 attempts but eventually it will start when it successfully detects the DVD and IDE drive.

    I am going to do some testing, first I will remove the IDE drive from the equation and if that does not work try without the DVD for a bit and see if it is stable.

    I also noticed the SATA settings in the bios and tried a few changes, (AHCPI? can't remember, but it did not boot into windows properly).

    I will let you know how I go, but wonder if you have any ideas on a resolution to this.

    Cheers

    Ok,
    So I found this link; http://forums.tweaktown.com/f69/giga...ci-mode-39032/
    Which suggests a registry tweak to get my OS to load in ahci mode.
    I have
    1. done the registry tweak rebooted,
    2. Changed SATA to run in AHCI mode.
    3. Started and let the OS udpate the hardware
    4. Restarted, let the computer boot and shutdown.

    This morning I have done a cold boot after the PC was off for 7 hours with success.

    I will try again after work which will be a 14 hour cold rebooot, so hopefully I will have a final post. :-)

    My DS3 board behaves strangely around 450Mhz too, above 444 for sure it wasn't stable at all. just like that for no reason, but above 460 don't know exactly at what point the problem dissapears, my old P31 board was the same between 377-382 and demands +0.1 MCH to boot just to fail anyway, very unstable FSB range, just stay out of it, at least +-5 away just to be sure, not to overlap with it.

    try some other FSB. I know 445 is sweet spot, and memory runs 1066 and all 4.0GH perfect combination, but it is just that bad coincidence, the strap changes there.

    If you can save me your bios settings to a file with F11, for me to try. I am tired inputting 100 lines of settings.

    Please post an ET6 screen-shot (Tuner -> Advance -> Voltage) to show the actual applied voltage settings.
    CPU PLL and CPU Termination (VTT) are usually too high when you overclock and have these set to AUTO.
    Using NORMAL for these settings is probably OK.
    The ET6 screen-shot in post #26 shows that CPU PLL = AUTO is too high.
