What is the lower vcore limited for a i7 7700k at 4.5 ghz?

[gasolin]

I have just a few weeks ago bought an i7 7700k and so fare i have oc'ed it to 4.5 ghz on all cores 24/7 at 1.160 volt, after some days i have today lowered vcore to 1.140volt (from 1.150 to 1.140).

I have tried google vcore at 4.5 ghz but im not shure what people have as lower limited to get an idea of what lowest vcore is.

I found this review but im not shure where the limitied is I7 7700k Review

What is the lower vcore limited for a i7 7700k?

gasolin,

No two processors are identical; each processor is unique in voltage tolerance, thermal behavior and overclocking potential, which is often referred to as the "silicon lottery" or luck of the draw.

The link you provided underscores this point. Minimum Vcore required for stability at a given clock frequency varies among different processor samples of the same SKU's. To answer your question, there is no "one-size-fits-all" Vcore setting.

The only way for you to know is to continue decreasing Vcore until your processor becomes unstable, which will differ from someone else's 7700K.

i know, i just want an idea to what the lower limit is, since i can't find any at 4.5 ghz using google to se what people use at 4.5ghz

There is no such thing is a 'lower limit' apart from 0.

Each chip can vary massively with their voltage requirements.
My 7700k is running at 1.280v with 5Ghz clock speed. But others could need upwards of 1.35-1.4 or maybe not even be able to run 5Ghz.

So fare 1.13 volt, it wants to run at 1.136 and ibt maximum 1.168volt, it frezzes a bit doing ibt but it finish after x10, so i guess 1.130volt is my lower limit since it's freezes a bit doing ibt
