Hi! I am right now running on a 4.0Ghz OC on my i5 3570K but the only thing i have changed in the bios are the Turbo Boost clock which i changed to 4.0Ghz and that is pretty much it, i let motherboard decide the VCore which is pretty high since it goes up to 1.29V sometimes :/ But when i try to change it to something static like 1.20 or 1.25 my games start to crash randomly with an "Application has stopped working" error and if i go too low, my computer wont even boot into Windows.. I would really like some help as to what to actually change, i would like to reach 4.0Ghz if it is possible, or is it possible i have just gotten a bad chip? My temps seem to be fine though as they are always staying below 60C when gaming and the seem to be fine when running Prime95 too as they only go to 65C at 1.29V. Any help would be awesome, thanks!

My specs are as follows:
GTX 980 SC
i5 3570K 4.0Ghz Noctua NH-D15 Cooler
16GB 1600Mhz RAM
ASUS P8Z77 V-LK Motherboard
EVGA SuperNova 850W Gold Rated PSU

Not sure why I linked Haswell stuff, you have Ivy bridge. You should be able to reach much, much higher clocks actually.

Try here: http://www.overclock.net/t/1291703/ivy-bridge-overclocking-guide-asus-motherboards

Give that guide a thorough read.

I have a feeling you are missing something fundamental to not be able to reach higher. Core voltage is the simplest determining factor, but if you have any other voltages that are reporting low you will want to increase those to at least be what the stock values should be.

Might look into CPU PLL voltage, which I believe is the equivalent to VIN, VCIN, VINPUT on haswell processors.

I followed the steps in the links you provided, but i can still not get my i5 over 4.0Ghz without using atleast 1.28V which i find to be very high, did i just get unlucky and got a chip that doesn't overclock well, or is there something else i could try? :/
