    questions:
    * how about speedshift and speed step. should they be enabled?
    * with the adaptive mode, i selected +. wasn't sure exactly what you meant by offset=auto(none), does that mean leave it at auto or put it to 0? for now it's left at auto.
    * i have avx on 3 as noticed temps go up bit more and things get louder in those situations, how does that tie in with that situatiion you mentioned about spikes? to tighten it up would i benfit from going back to avx-1 rather than avx-3?

    bios changelog (the ones not shown in changelog, i already had it there from yoru sugegstions in past posts)
    cpu svid support -> enabled
    bclk aware adaptive voltage -> disabled
    cpu core/cahce voltage -> adaptive mode
    additional tubro mode cpu core voltage auto -> 1.330v
    cpu load line calibration lvl 5 -> lvl 6
    long duration package power limit auto -> 4095 (this is max on this mb)
    short duration package power limit auto -> 4095
    ia ac load line auto -> 0.01
    ia dc load line auto -> 0.01
    cpu c-states disabled -> auto
    speedstep enabled
    questions:
    * how about speedshift and speed step. should they be enabled? - yes

    with the adaptive mode, i selected +. wasn't sure exactly what you meant by offset=auto(none), does that mean leave it at auto or put it to 0? for now it's left at auto. - offset means you can make a + ( positive ) *add some volts * to your cpu volts or you change the + ( positive ) to a - ( negative sign ) to * take a way * some volts - example to under stand , so say your cpu needs 1.3v for 5.0 ghz in * manual vcore mode * now u want switch to adaptive mode so you type in total adaptive volts = 1.3 v so you load up windows and you notice that your getting 1.328 v - 1.332 v under load ... so you go back to the bios under adaptive mode offset and change the + * positive symbol to a - negtive symbol ( we need to take some volts away ) and you would do some simple math
    1.300v = stability but adaptive is giving me 1.328 v
    1.300v - 1.328 v = 0.028 v difference thats what you type in offset volts - 0.028v so now in windows you wont see 1.328v you should see 1.3 v since you made that offset under stand ? same thing goes for + positive offset say you got a crappy 8700k that needs 1.4v for 5 ghz but in adaptive mode its only giving it 1.37v under load you would add a + positive offset of + 0.030 ( 1.37v + 0.030 v = 1.4v ) so your stable .

    i was saying that if you ( * do not use * ) a - avx offset you will or * could see * up to 0.040 v spikes under load on top of your already set vcore
    example 1.3v no avx offset = up to 1.34 v under loads in avx witch i was saying that if you use a avx offset of - 1 you will only see up to a 0.020 v spike vs the 0.040v with out one , if you use a avx offset of - 2 you will not have any or little volt spikes ( maybee 0.016 v tops ) .

    its a trade off to not get those volt spikes in adaptive mode . trade off is , instead of a constant 5 ghz @ 1.3v + 0.040 v spikes you get 4.9 ghz on avx loads and only 1.32 v spikes .

    some cpus dont spike as high as others as they have a better svid voltege table vs other cpus that require more volts for a givin speed .

    i read threw a 90 page fprum on over clock .net and drank a pot of coffee can learn alot from those guys that have been there done that for years .

    i only been around since the core 2 duo first came out e6600 @ 3.4 ghz .... lol

    thanks a lot mate. just posting back to say i've taken your advice on the settings and couple days in now with several hours in overwatch + 20ish runs of realbench and 5ish hours prime95 has proven stable. the small spike up to 1.344 comes in when the avx instructions come on from prime95 it seems, all other occasions logging with hwinfo the vcore is nice and low in idle and stable at 1.328 under load conditions. this marks the success of adaptive mode for me, which i had previous spent so many hours on and failed, so thanks for your help!

    if you " do not use " a avx offset you will see " up to " 0.040 v spikes in adaptive mode .

    example 5 ghz , load line=6 , ia/dc =0.01 , total adaptive volts = 1.28 v to be stable avx = 0 you will see spikes " up to " 1.312 - 1.32 v .

    if you use a avx offset of = - 1 the " volt spikes " will only be " up to " 0.016 v - 0.020 v
    example : 5 ghz 1.28v avx = -1 , = " up to " 1.296 v spike vs 1.312v - 1.32v spikes with out a avx offset .

    i was reading in the over clock .net forums and guy narrowed it down and tested 8 8700k , a few 8086k in adaptive mode and had it down to a science ,

    no avx offset = up to 0.040 v spikes
    avx offset = -1 = up to 0.016 - 0.020 v spikes
    avx offset = - 2 = no spikes or minamal up to 0.016v tops !

    so what i did was use my 8700k thats stable @ 5.1 ghz @ 1.36v manual switched to adaptive mode set a avx offset of = - 1
    total adaptive volts = 1.36v ( cpus svid tables work in 0.016 v incriments on load ) load line = 6 and now i only get max of
    1.376 v on avx loads ( +0.016 v spike ) on avx loads .
    playing games with out avx bf4 it sits @ 1.36v no spike ,

    i also tested 5.2 ghz with avx offset of =-2 @ 1.4v and didnt get any spikes period .

    in the end live with a - 1 avx and only get up to a 0.016v spike or dont set a avx offset and recieve up to 0.040 v spike . - 2 avx = no spike .

    this is awesome I have to test this also, I never use avx offset because I only dun 4.7ghz. but if this is true for my 8600k also then I am gonna push it to whatever frequency 1.25v will give me!

    was running occt on medium and it was doing 1.28v, when in every other benchmark and test it goes only to 1.18 max...…

    yeah it works tested it for a few days .

    load line level 6 and say 1.3 total adaptive volts to 1.3 no adaptive offset left at auto will give you 1.34v on avx loads .

    -set a - 1 avx offset and your 1.3v will only spike to 1.316v - 1.32v max max

    -set a - 2 avx and you will have 0 spike if at all .

    - dont use avx offset and live with 0.040v spikes
