Overclock i7 voltage

[zent]

I have an i7 4770K and im trying to OC to 4.4 GHz

 

I'm currently still messing with my CPU Override voltage ( which is my vcore voltage correct?, testing out 1.280 ( not sure how good that is?)

 

Also, my CPU input voltage is at 1.9 fixed. should I leave it at that or lower it as well?

1.28 is pretty good for 4.4. Unless you really want to go higher, I would just stay at that.

Is my CPU Override voltage my vcore voltage?

 

I have this set,

 

CPU Override VOltage: 1.250 now (might go lower since its handling it)

CPU Input Voltage is at 1.9V <- is this number normal?

I personally don't have a 4770k, and haven't overclocked one, so I don't know the exact specifics. However, if you were at 1.280v and were happy, then why not bump up the clock speed until it's unstable at that voltage?

I'm just wondering about this number here Input Voltage 1.9V. It seems high that's what it was at default but currently im messing with CPU Override voltage I'm not sure if I'm supposed to lower the 1.9V as well

What you can do is utilize a combination of auto overclocking, CPU-Z and Intel Burn Test to fine tune your OC

 

*Set MB voltages to auto
*run IBT

*monitor the voltage that CPU-Z is giving you

 

Auto voltage is almost always going to be more headroom than neccessary. Note what the maximum voltage is for your OC. From here, reboot the system and go back into your BIOS. Where your voltage is, input the max voltage CPU-Z gave you and slowly decrease it little at a time (pressing "-" should take it down .5v depending on MB) Keep doing this until your system bluescreens running IBT. Note what the lowest voltage you were using that remained stable. This should give you an idea what the ideal voltage is for stability at that overclock without resulting some insane headroom. The result is lower temps which is always a good thing.

 

When running Intel Burn Test, set everything to maximum and for 10 passes.

 

 

Pay attention to the core voltage when you are running Intel Burn Test.

 

For my system I utilize offset voltage overclocking so my system doesn't waste electricity when doing much and will ramp up to 4.6Ghz with appropirate voltage when actually working. (+0.010) Don't play with offset voltages if you don't have a grasp of what you are doing first.
