What is the difference between ;

Cpu input voltage and vcore voltage ?

I oced my i5 4670k from stock to 4.1ghz with cpu input voltage of 1.650 and vcore voltage of 1.155.

Is this good ?

Also load line calibraton is at level 2.
 
Input voltage is the voltage supplied to the CPUs voltage regulation modules, which are now on die. Vcore is the voltage supplied by the VRMs to the actual CPU cores.

Not much of an overclock, but it depends on your cooling and temperatures. 4.4Ghz - 4.5Ghz is not impossible.

Vcore can go as high as 1.35 (it will run very, very hot most likely, water cooling may be needed), Vinput can go as high as 1.9 safely, 2.0-2.2 if you have water cooling.

I run my i7-4770k at vcore 1.3, vinput at 1.8, LLC 1, 4.3Ghz, but my chip is not very good, hits 80C at full load.
 


I just reseted all my cpu bios settins to default and overclocked it back from stock up all the way to 4.5ghz. I noticed the difference in BF4,especially during loading times. As all the settings are set to auto , in cpuz it showing that the vcore being used is 1.299v. With prim95 it got high , but while playing bf4 on high/ultra settings im getting a super fine temp. I think vinput is about 1.9v. What should i lower ?

Should i stay with this ? Or maybe try a lower voltage?
Here's a shot ! : Its at 67degrees while playing BF4. Max it was was about 83 , but rarely exceeds 80degrees+. Cooler is coolermaster v6gt.

That's just about right for that speed. Temps are adequate. (I usually see the 80+ spikes during map load)

You can attempt to lower any of those values until the system becomes unstable. Any reduction you achieve will be a reduction in temperature.
 


Im now at 4.5ghz with 1.270 vcore and 1.250 cache voltage and 1.960 input voltage. Any of these are high or you think should be set to auto ?
