    Default P45 UD3P - Large RAM Problem

    Hallo,

    first sorry for my bad english.
    I have an large Problem with my P45 UD3P and the Corsair Dominator 2x2048MB DDR 1066 5/5/5/15, the CPU is a Q9550 E0.

    When i set everything to DEFAULT (FSB333x8,5, DDR1066) i can boot and everything is fine. Even DDR 1080 is no Problem.

    But when i raise the MCH-Core Voltage over 1,2V the Board loop in Reboots. I must turn down FSB to 325 (DDR 1040), then i can boot.

    I need higher MCH-Core Voltage then 1,2V for my Quad at higher FSB, but then i cant run DDR 1066or higher!
    (For Example FSB 445 and 2.4B=1066 -> not possible over 1,2V MCH
    FSB 433 and 2.4B=1040 -> possible with 1,2-1,4V)


    What is the Problem, is the Board damaged or the RAM incompatible?

    Bios is F7, i tried everything, even lower Timings, but this could not be the Reason, because the Board boots DDR 1066 or even higher with MCH<1,2V, but when i set MCH>1,2V, there is no way.


    Please help me,

    Thanks

    No on an idea?
    Can somebody with 2x2048MB DDR 1066 test if booting is possible with MCH 1,3V?

    I've got similar hardware as you, no overclock on my q9550 and have gone as high as 1.24V MCH Core with 1066 DDR2 with nothing but reboot loops.

    It means you have the same Problem, over 1,24MCH Voltage you got Reboot-Loops?
    What Memory you use?

    Could be ram incompatible ?, That brand Corsair Dominator might be picky on your UD3P, try use different brand for 2x2GB pop in and see what happen.

    Go for G.Skill

    The Memory is offical supported:
    http://www.gigabyte.com.tw/FileList/...-ep45-ud3p.pdf

    I have no other modules for testing, but i think, its a general problem, Gigabyte has massive problems running 2x2048MB DDR 1066 stable on the UD3P.

    With my P35DS4 i can run the memory with DDR 1100 on every possible MCH-Voltage.

    Try use updated beta F8a link at http://forums.tweaktown.com/f69/giga...st-bios-28441/ if problem go away ?

    @ Max25,

    Read this ram comptiable ram works with UP3P by review at Egg link at

    Customer Reviews Of mushkin 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) Dual Channel Kit Desktop Memory - Retail

    I am not saying you should buy it but get idea about reviews reports that brand works with UP3P right off the bat.
