    I have the Gigabyte UD4P /w newest F8 bios

    1 Sapphire 4870 1gb toxic
    Silversote 1000w Power Supply
    1 Samsung SH-203N DVDRW
    3x500 gb Western Digital Caviar Black in raid0

    i don't even want to oc my system but i can't get my ram work at 1866mhz/1.66v and timing running 9-9-9-28(i got some stability issues gives bc code 124 bsod).

    124 code means you do not have enough QPI/Vtt voltage set, raise that a bit and try again. If you still keep having issues give me your full settings so I can be sure you do not have other issues holding you back

    You may want to set IOH to 1.14-1.24 or so, and QPI/Vtt to 1.25-1.4 or so for that high of a ram speed

    Yeah for high speed memory (1600Mhz +) it doesn't always work out of the box unless you have XMP profiles which modify the QPI voltages for you. Memory makers/Intel should really clarify that if there is no XMP profile, you will probably have to up your QPI voltage yourself.

    XMP QPI Voltage values can often be not enough/incorrect as well because the amount needed is a Per CPU type of thing. I really think it was a poor idea to add that setting into the XMP Design process
