    I dont think ive missed many/any of the possible main voltage combinations in the past few months.
    Whats in the sig is voltages at 490 on either B or D approx,500 is a lot higher (memory v needs 0.12v for just 20 mhz).
    Cant get 500 stable on the D multiplier..but im not really worried
    Im getting better bandwidth on both Sandra and cache 32 at 490 D(obviously with different memory timings).
    Unfortunately tRD 9 as opposed to 10 is part of the solution.
    CPU will be running slower but overall pc performance may not drop..hurrah.
    Ill post exactly what works either here or in main forum once i get exact settings.(too much padding in my sig as it is :)

    More is not always the answer when it comes to P45 voltages, that is why I asked if you had tried plenty or not. Meaning tried less not more

    D should be MUCH more stable for you above 400 FSB than B, so I would imagine you have to much voltage into something or a incorrect ref voltage set maybe?

    tRD 9 is better then 10, what do you mean by what you said there?

    Yeh tRD 9 is better than 10,lower is higher so to speak.8 would be better but thats not happening.
    When you said A higher tRD might be needed for D,did you mean a lower one numerical.
    Anyway what I mean is for 9gb/s at 490ish I need tRD set at 9.
    The way things are going I may end up exactly on Pro j's signature settings :)

    Strangely enough tho I notice my nb temps are now running higher than at my old 500 fsb settings.Im now getting 5-6C diff between sys and NB temp under load.45C isnt but its interesting tho.
    Perhaps increased bandwidth is making it work harder even tho operating speeds are lower.

    No, when I said you may need a higher tRD for 400+ on D I meant higher numerical value.

    Ya, more bandwidth would make it work harder so that may be why you see higher temps

    Of course.
    I tried wth default settings (9x333, default voltages, perfomance enhance: standard) and 2D (2x333 = 667, 5,5,5,18), and I got dual boot issue. I think the 400Mhz strap causes it.
    But with 2B the computer starts normally.

    Ya I would expect the D multi's to give you issues at only 333 FSB, to use D normally you should be at 400 or above FSB

    I'm going to chime in here. I'm having some issues related to this in a thread I started about g.skill 8800s (PI series) on EP45-UD3P, have a look here for background if you're interested: http://forums.tweaktown.com/f69/g-sk...89/index2.html from about post #12 onwards.

    Basically I can't get that memory to pass memtest86+ at FSB 400+ using D strap. I've had one run of 15 passes with no errors using B strap but the machine behaves strangely when using B strap, double boots when just changing a single voltage setting, shuts down when exiting memtest etc. More details on my thread, perhaps you guys could take a look and see what you think. I've spent 3 solid days just memtesting and not really getting far.

    Double boot is normal when making certain BIOS changes, if you are stable on the B Strap then feel free to use it. It can of course perform better at certain settings, these were just simple tests

    Yep I know the double boot is "normal" when making certain BIOS changes but what my board is doing does not seem normal. Sometimes double boots when no changes have been made, sometimes turns itself off when exiting BIOS or memtest. It only does this when using the B strap. And pretty much every time I go into the BIOS when using B strap it gives the message:

    "The system has experienced boot failures because of overclocking or changes in voltages.............."

    It will give this message even when there have been no boot failures. So makes me a bit hesitant to use B strap. Haven't got around tp Prime95ing with B strap yet so will see how that goes.

    Sounds like then if you want to continue using the B Strap you need more voltage to something or looser timings.

    What FSB and tRD are you running anyway? Mind giving me your full settings, maybe I can see the issue?
