i7-4770k Overclocking [FULL SETTINGS INCLUDED]

[toon_mad]

OK, yet another thread by me and my determination to get a 4.5Ghz overclock!

I have struggled to get anything past 4.2Ghz so there must be a setting(s) somewhere that I must need to change. And this time rather than seeing my overclock in the dark I have spent ages writing down each setting, and here we are:

So this is currently a 4.2Ghz overclock stable (5 runs with RealBench), running 4 sticks of DDR3 at its native 2400Mhz with XMP.

As you can, tons of options

Surely someone can take a peek at these settings and determine what I need to change to achieve a 4.5Ghz overclock. Simply raising the vcore to 1.3v is not enough even at 4.3Ghz.

I would really appreciate some suggesting what I need to change

Cheers
