VCore jump from 4.4GHz to 4.5GHz

post #1 of 10
Thread Starter 
I had previously overclocked my cpu using a premade OC profile that came with my mobo, because I hadn't really looked into OC'ing all that much and wasn't comfortable with it completely yet. Recently I decided to have a go. All I have done was use the XMP profile and crank up the multiplier and set manual volatge. On the auto profile it was using 1.28v to get 4.2 GHz. I can get 4.4GHz at 1.328v however it takes 1.4v to get 4.5GHz stable (hitting 100 C on prime 95, so not too impressed with that temp) which, to me, is a massive jump...
Am I doing something wrong or is this just the brick wall of my chip?

Well I would say try a lower vCore and see if you can still boot.. have you checked out the many guides here for the different boards and chips.. for 4.5ghz and my Ivy Bridge I am at 1.310v Stable..

I would try lowering the voltage and see if you even boot.. if you do then try running a stress test to see if it maintains stability..

What kinf of CPU Cooler are you using..??

Below 1.4v @ 4.5GHz will boot but it won't be stable
I have tried the guides, same result

This is the CPU Cooler he is using, as stated in the Rig Sig:

Corsair Hydro H100i

All chips behave differently in overclocks, some may require more or less voltage for the same overclock and the same chip.

So I am not doing anything wrong, it's just my chip?

It's your chip.
My old A6-3670K took an extra 0.6V to get to 3.6GHz.

My chip needs 1.28v for 4.5GHz and a whopping 1.36v for 4.6GHz. Not all chips are created equally.

0.6V sounds pretty crazy for a voltage jump.

Think of it as a voltage wall, you need a huge amount of voltage to get any higher clocks on that chip.
Also, AMD CPUs have a wider range of voltages than Intel CPUs. My 3670K had a stock VCore of 1.32V (I think) and I had it set at 1.5V when I was running it at 3.5GHz.
