    You will be fine using 2.1V, that is pretty much the normal DDR2 voltage anyway, plus it is what your kit is rated to run at.

    Yes, I was saying 1.26-1.34 Vtt is what I would suggest for a 4Ghz overclock, that is why I mentioned all the rest of what I did so you can try to get things going so you can adjust this voltage.

    MCH ref is based off of the Vtt voltage, a percent of it. More info on this setting and how it works is in a link in my signature.

    I do suggest you leave it normally until you are trying to get stable, I only suggested you might need to adjust it now in order to allow you to be able to set a Vtt value which you said you cannot.

    Sorry, may have confused the issue regarding
    in order to allow you to be able to set a Vtt value which you said you cannot
    I read a post on this site suggesting that someone with my board could not POST when they had set these values, event to default, so I was just being cautious.

    I can set all the values in the bios, its just getting the right ones that will make my board post successfully.

    I have bumped the FSB to 445 for 4.0Ghz, so I can run 2.40B on the memory which gets 1068Mhz. I have tested the ram and with these speeds and it passed. I have set all the voltages to there default Auto values then tweaked Vtt and DRAM Voltage as per the link in your signature.

    I have run stable Prime95 and Intel Burn test with these settings, so I will wait till tomorrow to see if I can POST successfully.

    :-)

    Your cpuz SPD indicates that your memory is TWIN2X4096-8500C5C --- PC2-8500 --- 4GB Kit 5-6-6-15 @ 2.1 volts
    Let us know the details of your IBT test:
    1) How many loops were run (10 loops is sufficient)
    2) Amount of memory tested
    3) Threads = ??? (AUTO, 2, etc.)
    note: Threads = 2 for dual core processors is the most rigorous test where cpu core temps will be hotter and the Gflops score will be higher. Using the maximum amount of memory to be tested (for your system) is a more demanding test.
    4) Which Prime95 was run? Blend? Small FFT? Large FFT?
    5) How long was the Prime95 test run?

    Please post your most recent bios settings and a screen-shot that includes:
    • Memset using the SPD and ">>" tabs
    • cpu-z CPU and Mainboard screens (several instances can be run at the same time)
    • EasyTune6 --> TUNER tab --> ADVANCE tab --> VOLTAGE tab (only the Voltage tab is needed)
    • CoreTemp screen [for your cpu's VID (Voltage ID)]


    This will let us better help your tweak your bios for improved stability and/or performance.

    Hi,

    Firstly..

    Your cpuz SPD indicates that your memory is TWIN2X4096-8500C5C --- PC2-8500 --- 4GB Kit 5-6-6-15 @ 2.1 volts
    I think you will find that this memory is 2 x 4096 which is an 8 GB kit. This is not my memory.

    My memory is CM2X2048-8500C5C which is a 4GB kit, 2 x 2048 and as per the screen shot it runs @ 5-6-6-16 not 15.

    I have done the Intel Burn test 10 loops at maximum, auto threads when @ 4.0GB. Image to follow.

    I have only Run Prime95 (2 Threads) in blend mode for 1 hour. And MemTest for 40 minutes, so I will do some longer runs once we get closer to getting it right.

    All testing was done with the following settings:
    Code:

    CoreTemp (Note: My cpu does not register Core Temps below 37/40, but the Temp2 on the CPU registers correctly)

    Thumbs up Re: GA-EP45-DS3 E8400 Overclock cold boot issues, faulty ram channel?

    It looks like I cut and pasted the wrong model of memory for your system.

    CPU Host Frequency (Mhz) .................: 400 Mhz
    Your bios template is incorrect, you're running at 445MHz.
    At 445MHz with the 2.40B memory multiplier, you'll improve your memory performance with tRD = 8 or 9 for both memory channels, lower = better performance. See if 8 is stable.

    tRFC = 52 or 54 will give better performance, lower is better.
    Lowering tRD (Static tRead Value aka Performance level) will improve performance more that lowering tRFC. Hold off on tweaking tRFC until later.
    Tweaking the remaining Advanced Timing Controls will be done last, after you've reached your final stable o/c goal.

    If you run CoreTemp during your stress tests, you can enable auto-logging which will include time interval entries for:
    • Date
    • Time
    • Temps for each core (current, low, & high)
    • Core load and speed (for each core)

    Each time you start Coretemp, a new log file will be created in the CoreTemp program folder.
    I think that older versions let you create a TXT or CSV log file.
    (Note: My cpu does not register Core Temps below 37/40, but the Temp2 on the CPU registers correctly)
    Yup, chalk it up to stuck cores. Don't worry, this is normal.

    With your dual core cpu, when running IBT,THREADS = 2 should raise core temps a bit and improve the GFlops scores. This will be a more demanding test.

    Good work so far.

    Ahh it's good to hear you can actually set Vtt, that is nice to hear! I thought you couldn't and that was going to be an issue.

    I am sure Profjim will get you going so I will move along, if you guys need my help you know where to find me
