    Processor Input Voltage on i7-4930mx (overclocking)

    Is there anyone who knows how high the processor processor input voltage is set to default (the standard Intel Specified voltage - factory Configured maximum voltage) on i7-4930mx ?
    Can Dell add some guidelines in the motherboard for how much volts which is standard for the processor. :D

    In the thread you made Mr Fox in post # 25 (How to Overclock the 4930MX to 4.3GHz with a Messed Up BIOS) You wrote: in the opening post I show to use "Default" (which turns off Adaptive mode) and an offset and That actually works OK for me.
    What do you think is the best of this adjustment or only a fixed voltage + offset? I use 1.200mv + 17mv offset (I must have it). What volts becomes when you set default?
    In adjustment input voltage, you can choose Default or 2-3-4v etc. Is there any real difference on how things work?

    Edit: You said (I do not know the default, but Manually setting it two 2V Seems better on the Alienware 18.) Why do it works better with to put Core voltage to 2v?
    Can I risk soft brick with and put Volts on 2 or 3v instead of Default in CORE VOLTAGE?

    With XTU the options go up in 1V increments. 1V is obviously not enough, so the logical thing would be to set it for 2V.

    Edit: I have read a thread where it says: VCCIN CPU Input Voltage, Vrine voltage regulator (FIVR) Estimated requirements for 4.4 / 4.5 GHz
    for an average 4670K / 4770 K is1,75v and Max recommended air cooling is 2.10 V. Can Temperature increase by putting processor input voltage to 2v? I thought about what is best adjustments of 4.2 and 4.3ghz.
    Here is a Norwegian website about overclocking Haswell. http://www.tek.no/artikler/guide-overklokking-av-haswell/137463/2?key=BoCngbNv

    Well, 1V is not enough. 2V is more than needed. The available options are 1V and 2V with nothing in between, so it's not too hard to decide which one to choose. ;)

    All voltages will have an impact on temperatures.

    Yes unfortunately it does so. Normally recommended VCCIN CPU Input Voltage to be 0.5 v over core voltage. With my processor on core voltage 1.217v then should VCCIN CPU Input Voltage been perfect on 1.717v. Unfortunately I do not know exactly what the real volts value is on my Alienware. If I use VCCIN CPU Input Voltage at 2v I do not know if the temperature is going to increase .. 2v on VCCIN CPU Input Voltage I think sounds very much. :D

    It is obvious :)
    1. I did not get clearly answer to the question that I asked. You said (I do not know the default, but Manually setting it two 2V Seems better on the Alienware 18.) Why do it works better with to put processor input Core voltage to 2v? :D

    2. Under comparison of volts adjustments in hwbot during other cpu profiles, then it says 0v under processor input voltage? Why?

    No, this is not the voltage used we are referring to, just the amount made available to the CPU to use on demand.

    VR in is the voltage going to the on board voltage regulators.

    and you don't want those to melt or burn if you send to much to them so be careful papsun..

    2v is ok for them but yes not very fine grained adjustment lol.
