very low vcore for i5 4670k

[mallebabbe]

After a lot of testing, I reached the lowest possible vcore I need to have my i5 4670k running at 4.5ghz.
I did a lot of test, and its complete stable at 4.5ghz with a vcore of 1.170v.
not bad I think.

cpu input voltage 1.7v ? 😵

Congrats. That is a nice voltage for 4.5. High clocking/low voltage chips are few and far between but there are a couple of us here at AT, myself and balla are two. What are you using to stress test it?

I stress test it with itb, and linx65
I don't use the new prime95, because I find that temps not realistic any more.
I now I can benchmark at 4.8ghz with 1.285v, and it boots in windows, and I,m still able to do things on the desktop at 4.9ghz wit a 1.3v
The problem I have is that it is a very hot cpu, and I am only on a corsair h105.
