Ok so I have my i7 950 running stable at 3.83ghz now with 1.3185 Vcore and +150 VTT with RAM @ 1830mhz 8-8-8-24-74-1T
So i tried a 22x183 with 1.33 Vcore and got a stop code of 00x000003b read up on its memory related to be exact excess pool usage or w/e so should i try more VTT or lower my CPU multi?  or increase the bclk instead?

    Have you tried 200X20 with a 2:10 memory divider and 20X uncore? I would try going up on vtt. My dominator set requires +300 to run @2000. If you stay where you are at now(22X183), i would try a little more than +150 to see if it works for you.Maybe +225 or 250?

    Ok so ive tried a different multi and blck Vcore all the way up to 1.38 no dice i get weird BSODs like 3b 1e etc.  VTT at +250.  tried 20x200 with 2:8.  Tried odd mult of 21x193 no dice.  At this point should i consider turning off Vdroop and putting the Vcore at around 1.35? temps maxed at 82C while running linx but it did not finish. BSODed on me. 
     
     
    My system is presently stable at 21x183 @ 1.3175 Vcore. Ram @ 1830 with 2:10 8-8-8-24-74-1T with +150 VTT.  This is 12 hours prime and 25 passes of Linx stable.
     
    All other voltages:
    QPI PLL 1.2
    IOH Vcore 1.2
    ICH 1.15
    CPU PLL 1.65
    everything else i left on Auto.

    If it helps you can check my settings passed linx 50 times But keep in mind I have CO edition. and add one notch up VTT PWM  frequency to 3... ( it is  not in the picture) every thing else is as shown

    Overclocking is useless to me if it is not rock stable.

    Bring your CPU PLL back up to 1.8
    auto the other PLLs except QPI increase that to 1.2
    does your RAM need that whole 1.65v?  my board overvolts so i only set to 1.63 to get 1.65.
    You also may want to try a tad more IOH since technically your running a quad SLI setup. try 1.3
    Why is your Vcore so high BSOD? If so which one
     
    250 VTT is about what you will need at 1900+mhz
     
    Loosen the RAM timings way too tight kit is ment to run at 8-9-8-24.  Then auto everything except command rate set to 1T.
     
    Re enable execute disable bit also has nothing to do with overclocking its a fail safe for viruses that kill CPUs.
     
    As for the multi post sorry was so over joyed i hit 4ghz i forgot i had this thread already.
