    Hello peepz

    Just got my new rig.

    Asus GTX770 DCU II
    ASUS P8Z77-v
    8GB DDR 3
    Intel Core i5-3570k

    I am planning on overclocking my CPU on air (Noctua NH-D14). What I want to know is the following:

    Do I need to up the voltages of the CPU from the get-go or can I simply start by raising the multiplier until it starts becoming unstable and then I start upping the voltage ? Are there other things I should adjust in the bios ?

    Sure, certainly one way to do it. This is how I usually start my oc as I like know what clock I can get with default voltage plus you're not running unnecessary amounts of voltage through it.

    Yes, but I'd suggest checking out some guides first before any over clocking.

    Hi

    Welcome to guru3d !

    I have roughly the same setup, and i am also getting a 3570k soon. To get you started read this and this.

    The first is more of a general guide on how to overclock ivy-brige cpu's the latter is more related to your motherboard and cpu.

    Hope that helps.

    as a nh-d14 owner i can only say this dont put the pwm cables on and put the 12v ones second buy a descent thermal paste like the coolaboratory liquid pro and then start your overclocking

    Yeah, basic way is to increase multiplier a bit then see if its stable on the base voltage, then increase if its inadequate. Just don't touch the BCLK and leave it at 100Mhz.
    There are usually some guides per motherboard and these are helpful to get you for in depth OC.

    ^ This is a great guide fro you.

    Essentially it boils down to this:
    You want to get the highest possible clock at the lowest possible volts/temps. which is 100% stable.

    I have managed to stabilize @ 4.4GHZ at a constant 1.232v. Now I want to start using offset mode but things aren't adding up.

    My VID under load is 1.2810v, so does that mean that I should subtract my voltage from my VID e.g. 1.281(VID) - 1.232(Vcore) = +00.49 (+)

    Or do I have to subtract my VID from my Vcore e.g. 1.232(Vcore) - 1.2810(VID) = -00.49 (-)

    I tried using +00.49 offset but then my Vcore would fluctuate between 1.256v and 1.264v, when using a offset of -00.49 my vcore fluctuates between 1.227 and 1.240v, this is under 100% load btw.

    When I set my LLC to extreme my vcore would overshoot to 1.272 when I lower my LLC to high it goes to 1.240v.

    Does this meant that an offset of -00,49 at high LLC gives my the closest to 1,232v which I found stable ?????

    Any help would be appreciated.

    Please bear with my n00biness :):)

    See if you can not use LLC. It's not very much needed only to help in case if the system vdroops too much.

    If you tried using +0.049 offset and you got 1.256 and 1.264 as result, then add more offset! :D Set it to +0.060 for example, that should get your desired value. :)

    I have LLC on normal for example, on a Gigabyte board. Also use dynamic vcore. :)

    I'd leave llc on normal if things are stable. If you want lower vcore, go with a larger offset, like Deathchild suggested, until you're hitting the vcore you're after.

    Ok so just to make sure I understand correct:

    Higher offset + lower LLC is better than > lower offset + higher LLC ?

    My Board has the following LLC options:

    Off
    Medium = 25%
    High = 50%
    Ultra high = 75%
    extreme = 100%

    Which should I use ????

    It seems i'm experiencing quite severe Vpoop *cough* Vdroop lol

    With an offset of 0,060+ and LLC @ medium (25%) CPU-Z reports Vcore of 1.272 but under full load it drops to 1.232 - 1.240 without LLC it drops to 1.216

    If I lift my offset to 0.075 and disable LLC then CPU-z reports my vcore as 1.292v in idle and the vcore drops to 1.232 - 1.240 when under load, is this ideal ? I need around 1.232 to 1.240 for 4.4ghz to be stable but im concerned about that 1.292 !

    enable power saving states in bios, that way you'll have low idle voltages and under load you'd have 1.232-1.240.

    So, should I set a manual voltage ?

    ****
    Guys please excuse my ignorance, and please try to bear with me :)

    Are you saying I should disable LLC completely and up my offset to compensate for Vdroop ? e.g the required Vcore for 4.4GHz is 1.240 if I set my ofsett to +0,065 then my voltage in cpuz is 1,282.

    from 1.282 if I start lets say IBT then my Vcore drops to 1.240 which is the Vcore needed to run @ 4.4 so is the 0,065 offset + LLC disabled better than say 0,040 offset and medium llc @ 25%

    Should I increase the base clock from 34 to 44 or the turbo ration from 38 to 44 ?

    I'm using turbo ration :)

    4.7 @ 1.38v, no turbo, set the multi.
    llc at max.
    pm me if you like if you have any specific questions or such.

    this is mine: (48 on the multi and 101 on the pci lane) I use no power saving and I run these clocks 24/7, though I use more than 1.4v)
