    FSB Overvoltage Control may need tweaking at 1125MHz or higher.
    You might need to loosen primary memory timings at these speeds or higher.
    I'm a bit puzzled at how quickly you needed to use tRD = 10 when your system was stable with tRD = 8 at slightly lower speeds (440 FSB?).

    For 2 divider?

    2 divider took one or 2 less tRD than 2.4
    2d worse than 2b

    At 450fsb 2.00B tRD 10, 2.40B 9

    At 448 think 2.00B used 9

    Salty, you are disgustingly organized!!
    That's a great chart you posted!!!

    My EP45-UD3P used the same tRD = 8 setting with 2.40B up to 458 FSB and memory = 1102MHz stable.
    Obviously there are significant differences with your X48-DQ6 mobo.

    I don't think that upgrading to DDR2-1100 memory will help much.
    DDR2-1200 memory would probably use faster memory speeds with 5-5-5-15 primary memory timings.

    Couldn't the bios stay on the 2.40B divider for even higher fsb?

    You've got Mushkin. Can't get that here in Australia.

    Don't think the next volts up such a good idea, from temps point of view. Of course, anyone thinking it's safe can say so. So what I can get stable at 1.3625 bios volts is my current thought.

    When I updated to the F8e bios I lost my early 2.00D and 2.00B profiles.
    What is left in 2.00B:

    Tried the GTLs yet? Maybe you wont have to increase vtt so much.

    Have to read Global a few more times yet before it sinks in. Is that the one?

    I know that too little vtt is also bad, but don't know the lower limit. Considering it's remarkably stable at +.15 there was no incentive to explore the lower limit.

    Is there an adverse effect to +.15 vtt?

    Before I ask any more questions, will read it again.

    The "Global" link is the one I originally linked to.
    I'll check out the "Practical GTL" link where the poster has over 3K posts.
    Your VTT setting is reasonable. I generally don't like running any settings at their highest settings.
    Lower voltages are preferable, but instability can result with VTT that is too low.
    FWIW, my system was stable with MCH Core = 1.26, but it felt "better" with 1.28 volts. I mention this only as an example.

    From what I'm reading I have the impression that this is generally for high fsb, like > 460. But it is interesting that it can allow the use of a lower voltage level. Still reading.

    I have poor impulse control.

    4.37GHz, 460x9.5, 2.00B = 920MHz Ram

    May try 2.40B = 1100MHz Ram speed, but must be close to limit.

    Temps were recorded at ambient temperature of 25C.

    I have poor impulse control.
    More like NO impulse control.
