should I enable or disabled multi core enhancement? I've just left it on for the time being but I've read that it should be turned off?

it's because of a what's referred to as VDROOP.
this can be counteracted by your LOAD LINE CALIBRATION settings.
what kind of processor and motherboard do you have?
probably a sandy/ivy or fx series right?

its the 3570k with a p8z77 v-lx

if you dislike this drop in voltage,
increase your load line calibration to the maximum.
It should stay at a lower idle voltage and increase a little under load.
on your motherboard it should be labeled as "extreme"
there are five settings, choose the highest one.
just make sure you stress test of course.

ok thanks ive turned it to extreme, with the multi core enhancment, should that be enabled or disabled?
Multi core enhancement has nothing to do with LoadLine Calibration. Multi core enhancement basically puts the highest turbo multiplier on all cores under load. Let's say you have a 3770k. The base frequency is 3.5ghz. Under normal circumstances, it will be at 3.9ghz if one or two cores are being stressed, 3.8ghz if 3 cores and being stressed, or 3.7ghz if all 4 are under stress. If you enable multi core enhancement, it automatically puts the turbo multiplier to 39 under any load situation, regardless of how many cores are being utilized.

So basically it results in faster performance, but the offside is a little more heat and power consumption. You should be overclocking anyway past the highest turbo frequency, even at stock voltage you should be able to achieve higher than the highest turbo multi (most 3770ks get to ~4.2ghz give or take 200mhz on stock voltage). It's up to you, I would keep it enabled if you're at stock but you should be overclocking anyway so once overclocking comes into account it doesn't matter.

LLC controls vdroop under load, which for overclocking typically you want a more steady voltage rather than a drop off. I recommend setting it to ultra high on Asus, but again this is irrelevant compared to multi core enhancement.

I hav my cpu sitting at 4.7ghz with 1.28v , so I should turn it off? I did turn it off earlier but the only difference I noticed is it allowed my cpu to idle at 1.6? atm it just sits at a 24/7 4.7

that's up to you. some may experience lower idle temperatures with it off.
who cares about idle temperatures though?

guys i have recived pc with oc out of factory, its 8700k at 4,8ghz i have few questions so bare with me here.

im noob at oc'ing and i dont really like it since voltage is higher and heat output also, not to mention degradation of its life (i prefer more my hardware to live longer then extra 10 fps)

i have multicore enchancment enabled (maximus x mobo) its set on auto, but under that setting i have manually applied overclock on all cores at 4,8ghz vcore is manually set to 1.25v (thats highest voltage chip will run under load correct?) ram is running at 3200mhz @ 1.35v corsair vengence

my question is (well i have few) does manual overclock override multicore enchancment setting so basicly it dosent matter is it on or off at that point?

second question is, if i decide and i probably will to return my bios to its defaults, i plan to turn MCE off, should i leave vcore at auto and if yes should it run under lower voltages at its default clocks then with this overclock profile (1.25v) i curently have?

also, i would like to keep my ram at 3200mhz cause well i dont give a **** if it die xD and cpu benefits from faster ram. should i just pick 3200mhz option from setting for ram oc and im set to go? voltages should be applied correctly by system default i believe so no need to manualy tweak oc of ram?

i would apreciate if someone could answer all my questions in detail, i know its pain but its important to me. i want this thing to last me. in future i might use this oc profile i have but atm i dont really have no need for it.


edit whops i just bumped mega old thread, sorry, went into it from google xd
