A little confused on V core offsets

[reapz]

ok im currently over clocking my 3570k to 4.4mhz currently stabilizing
my vcore is offset with +.10 i left turbo offset to auto and im only pulling 1.16V on full load
sooo what is the pros and cons to using vcore offset voltage or using the turbo offset voltage?
is there somthing i missing because im able to hit 4.4 with just using core voltage offset and it being decently low voltage temps not hitting 80C more like 76C should i be using turbo voltage offset and not change vcore??
thanks guys

what motherbaord are you using?

the advantages of vcore offset is the ability to utilize Intel Speedstep (EIST). speedstep will down clock your CPU when idle or when the CPU is under a light load. this will lead to a slightly cooler CPU in the long run. as for disadvantages, i cant seem to find any as your turbo voltage offset can counter-act the disadvantages that come with offset vcore which is the fact that offset vcore is applied to both idle and load voltages.

as for turbo voltage offset, depending on the value (lets say +0.10v), when the CPU is running at the specified turbo speed it'll add an additional 0.10v. so if your CPU is using 1.16v on full load @ 4.4, it would be 1.16v + 0.10v = 1.26v. this is quite a jump in voltage which may lead to a jump in temperature. you can try starting with something like +0.010v instead.

offset vcore will do exactly what turbo voltage offset does except it will also apply the specified value to your idle voltage. so if your unstable during idle, using a positive value on the offset vcore would help keep the chip stable during less intensive work loads.

so lets say your 4.4ghz overclock is unstable during the less intensive work loads. what i would do is apply a positive offset vcore and test until i find the right voltage; but, doing this will also raise your full load voltage. this is where turbo voltage offset comes into play, using a negative equivalent value as the offset vcore will effectively get rid of the additional voltage being added during full load, allowing you to keep your load temps under control as well as keep your CPU stable at idle. i hope this will help you get a general idea of how offset vcore and turbo voltage offset can be used together.

your temps seem quite high for only 1.16v, are you on a aftermarket cooler? or are you using a software that came with the motherboard that's showing you those temps?

asrock extreme4

hyper plus cooler

and i just got it stable but i have turbo offset set to auto and i may change it up if it runs cooler using a turbo offset

4.4 stable at 1.16V temp maxing at 73 average 71C
using core temp 1.0 rc5 (may need to update lol)
and prime95 small FFTs to test i ran it for 6 hours no bsods
also using cpuz for voltage check
i believe is set vcore offset set to the second +voltage .10v or .010v? sry that was earlier today ill have to go back in and check bios

i just wanna make sure im understanding this. so i would want to apply a negitive voltage to the vcore offset and the exact opposite to the turbo vcore EX.. -.10v offset vcore +.10v offset turbo. ? making a lower idle voltage so cooler idles and yet still get the voltage i need to overclock the cpu?

you can probably do either or however, id recommend using a positive CPU offset vcore and a negative TURBO offset. your voltage of 1.16v at full load is your turbo voltage as at full load your CPU will be using the specified overclocked speed; now lets say you don't need that much voltage... applying a negative turbo offset (or even lowering the turbo offset) would result in a lower amount of voltage being applied ONLY when the CPU is under a good amount of load. if you use +0.10v on the CPU offset vcore, the amount of 0.10v will be added to both idle AND turbo speeds. there's also something called LLC (load-line calibration) which can be used to control your voltage as well. so, think about CPU offset voltage and Turbo voltage as fine tuning methods for the amount of voltage being given to your CPU while LLC can be used to either raise the voltage slightly above the specified voltage (so the voltage being set with CPU offset and Turbo offset) or have the voltage try and stay under the specified voltage.

the behavior of LLC will differ with every motherboard. from what i remember on the asrock extreme4, it used percentage values and was extremely confusing (it may have been because the BIOS i was using was quite new) but, if i remember correctly i set it to 75% and didn't touch it because the CPU voltage would fluctuate (+ or - .015v to .020v) even @ 100% load at any other values.

there's a lot more information on the function of LLC and it should effect your idle voltage to a certain degree as well, i just can't remember on the top of my head right now ^_^

my PLL has 5 stages with stage one being vcore 100% all time and stage 5 dropping from 100% with the steapest decline im running it on stage 4 right now ive heard people say stage 5 is better and some say try and get it in the middle... so i dunno but i do notice the differene of voltage applied the closer i get to stage 1 or 100% vcore

also i will prob take the boost offset off auto and try negative offset voltages hopefully lowering the temps... maybe doing a higher oc later on.. not sure at which point it becomes pointless with gaming. i used 3dmark11 i think its called its a demo on steam but i notice on from 4.2mhz to 4.4 that i had almost 50fps on the dx9 demo part and then it drop as 10 11 came into play i think only abt 5fps max..
