    i actually went back and tried for 3.4 after reading another thread u helped a guy with and i managed to get it stable for about 3 hours of prime 95 small fft testing. ill post my settings when i get home later, but i had to use a vcore of 1.6v due to vdroop. cpuid has my vcore at 1.504 under full load when testing at 1.6. lower vcores were 1.488 or lower which wasnt enough. is it a huge deal that it crapped out after 3 hrs in testing? i havent maxed out all the other voltafes yet so i might up those for stability. temps were only around 70℃ from what i saw. now i.d try for 3.6 but the onpy higher vcore setting i have is 1.8 and i doubt 3.6 will run at 1.6 vcore if 3.4 barely does. any suggestions and is it safe to run 24/7 with 1.6 vcore if vroop makes it lower and temps are ok? thanks for all your help

    Wow, at only 3.4 you should not need 1.5 actual voltage. So you may need to be adding more Vtt or PLL

    What is your full settings for the above tests?

    My vdroop is horrible, its about -.096v under load. Vcore at 1.6v and cpuz reads 1.504v during testing. Its about 1.538-1.552v just sitting at the desktop. Hope you got some ideas to get this vcore down, i've been seeing threads about people with Q6600 and the same 1.325 vid and they're running 3.6ghz at 1.5v vcore. I'm running 1.6v vcore and its crashing around about 3+ hours in prime95 using small fft testing. You know of any safe ways to adjust the vdroop with this board?


    *I'm also using bios F10*

    Vdroop Mod I linked here tonight for another user >>>
    http://forums.tweaktown.com/f69/will...y-board-29764/

    Try this, remove a set of ram so you only have 4GB so we can rule that out as a issue making you feel you need so much Vcore. Ya, some chips need more then others but this is looking a bit extreme

    CPU Vcore….……….........................: 1.600v << Less...., maybe try 1.525
    CPU Termination…..... 1.200V*.......: <<< 1.56v << Set to 1.425-1.45
    CPU PLL…………………....1.500V*.......: << 1.65 << Set to 1.55-1.59

    CPU Referen.…………....0.755V*.......: <<< 0.990v << Set to Auto



    MCH/ICH
    MCH Core…………….....1.100V...........: << 1.260v << Set 1.22-1.24

    probablthout a set of ram till this weekeny wont be able to try wid, but lets say when i do try it my system tests stable with the voltages u posted. does that mean im out 4gb ram to run it at those settings or is there a way to do it? also what happens if the ram is not an issue? i read that some people say quad/dual cores sometimes have fsb "holes" where they might not run at 400 mhz but do fine at 399 or 401. is that a possibility?
