    Default 3570k + z77x-d3h possible vcore issue

    Good morning ;)

    I today turn to you, because i do think i have an issue with my motherboard or processor.
    2x4GB Corsair DD3 1600 CAS8
    Corsair HX650
    Gigabyte GTX660Ti OC
    Hyper 212 EVO

    I bough this new rig end december, setup to run 4.2 or 4.4 h24.
    That was done according to my "internet datamining" ^^
    3570k could run 4.4 with ~1.2V max, and hyper 212 could dissipate all this power.

    So, here comes my issue: my i5 needs a very high vcore.
    x42 needs 1.260v
    x44 needs at least 1.38v

    It's one week now i daily reset my bios, test different parameters suggested by users on french forums. And result is always the same ... 1.26v for 4.2 and more than 1.38v for 4.4
    XMP enabled or not, memory unsynced or not, turbo boost enabled/disabled, all levels of llc are some of them.

    note: i use latest f18c beta bios because it's the only one i can run without intel usb issues and bios access. i did all the overclocking voltages tests with F16 and F17, with same results.

    Then, here come my little questions, if some of you mind helping me with answers ^^
    1. are those voltages "out of" 3570k regular range? i use to see oc'ed 3570k @4.5 using 1.2v or less. @4.2 with 1.1v etc ...
    2. if you can confirm i may have an issue, how can i (if possible) know if this is cpu-related or motherboard-related?
    3. maybe, any suggestion concerning how intel can accept to RMA the processor?

    Thank you for reading me,
    Tweakdown users, you're my last hope :)

    it depends on each cpu,some will need more voltage and some will need less,ive seen a few 3570's need 1.35+ for 4.4ghz/4.5ghz

    if you were only needing 1.2v before have you cleared the cmos by leaving out the motherboard battery for 30 minutes? then load optimised defaults in the bios and re enter your oc settings

    you can also set cpu pll to 1.65v from 1.8v,this should let you use less cpu voltage to be stable at load

    ok, thanks for answer :)
    then, it seems i just spent 200$ on a @#%y proc, i'm just so happy :(

    to answer your sugestion, yes i already tried with cleared cmos. i even tried most of the bios available (official and beta) on this forum :)
