    right oh, tried your settings ( phase adjustment options were auto/0-normal/1-advanced so i didn't change them ) running the F5i bios and it wouldn't get past C1 in the boot process
    this isn't a new build as such but the parts are new to each other gfx and ram from clan members 5850 flashed with another bios and just cranks :) the cpu from a younger member with no clue to overclocking ( yup a ferrari in a little old ladies garage in car terms ) the board is nearly a year old same with psu .

    after those settings failing i thought i'd set it all back to how i had it but go 375fsb so ram was under 1600.... it booted first go.
    this mobo should do 400fsb and 1600mhz ram standing on its head, just doesn't make sense

    Well there is no reason to struggle with the 1600, you may get better performance with higher FSB and lower ram frequency.
    You booted with DDR-1500, try 450FSB wth 3.33D multiplier.

    Yeah I can get 450 so long as I leave the ram below 1600. I have read up on the board and it originally had 1600 as an OC level so would I be right in assuming that even though the bios has made it possible to support 2000mhz the hardware on the board isn't up to anything but a theoretical 1600 that's not actually garaunteed as it's an oc speed??

    It is more likely a BIOS issue. As I said there is no reason to get fixed on just numbers as memory frequency.
    If you can set it to run at 1333 5-6-5-20 at 400FSB, memory performance will be just as good as 1600.

    Those settings seemed to work without a reboot dance.
    Fsb400@vcore 1.25v, ram 1333 5-6-5-20@ 1.6v other voltages as above.

    Should I dump this board and go with a newer p45t ud3r or something as they seem to support 1600 natively?

    No one will guarantee it will run memory at 1600.
    google shopping show zero stors that sell GA-EP45T-UD3R motherboard. When you buy a motherboard you better go with best sellers that will have continued support and updates.
    You must realise that memory performance is not that important.
    Fine tune those settings, run a memory benchmark, and compare them to others(at the same chipset/FSB) and you will see they don't fall behind.

    well spoke too soon
    bsod :(
    tried same ram settings at 1333 no joy - bfbc2 would hang and crash
    so i'm at 6-8-6-20 1333 nearly stock everything ( gfx and ram on auto and standard for the performance settings or again it will fall over )
    all stock settings is ok for my sons computer which is where i may just put this board as anything is better that the as rock p43twins thats in the cupboard, and there does seem to be a very limited supply of 775 ddr3 p45 boards.. so what do i aim for as a replacement? money doesn't really matter but having said that a $600 rampage board would have me on the couch for the next year.....

    Can't just overclock and expect everything to be stable without stress testing and fine tune it first.
    1333 CL6 is equivalent to 1066 CL 5 which is great. Was this with default 333MHz FSB?.
    Post full settings and we'll be able to comment/suggest changes.
    Could you also post a screen capture of MemSet main and SPD(click spd) windows.
    You can find MemSet in the programs sticky.

    it seems like anything near 1600mhz ram speed and it does its reboot dance

    @chike i realise it takes a bit to stablize OC settings but this system was stable @400 fsb with bugger all changes to bios ( 1.25vcore and ram at 6-8-6-24 1.6v, mch at 1.2 ) everything else was set at auto or hard set stock voltages. then slowly but surely this boot dance comes in and now even going above 1333 is dodgy.
