Can\'t reduce voltage on e8600


i've been reading a lot on OCing last two days and decided ONCE AGAIN to increase my E8600 speed to 4.4GHz... but regardless of all the changes i made in bios the part i can't change is voltage... i set ram voltage to 2.15 (from 1.8 default) which is said to be enough by all posts on Corsair CM2X1024-6400C4. and the CPU voltage that is 1.54V for 4.26GHz at the moment on AUTO setting in bios. and if i try to change it manually it doesn't reduce to such impossible voltages like 1.4.... i've read a post of a guy who has 4.40 on 1.4V... why doesn't my CPU even boot on 4.0 on 1.4V....?

  1. here are the basic specs:

  2. come on, drop at least a single line...?
  3. It may be limited by the motherboard- Weird though
    Have you tried differently ?
    what exactly did you do ?
  4. Hi,

    What do you mean "impossible voltages"? Try confirming that 1.54 is being fed with core temp our cpu-z.
    Also, turn on "load line calibration" (reduces vDroop) and that might change things in your case. It will make the vCore more stable.
    Finally, one person being able to boot that speed with 1.4v doesn't mean everyone will be able to do it. Chips are different, boards are different, etc...

    Hope this helps!
