For more a year now I've been researching on the best settings to use for overclocking for the MSI Z97 Gaming 3 motherboard and for my i7 4770K. I feel like my motherboard settings are holding me back from getting the most overclocking potential out of my i7 4770K.

I've also been reseaching for the right stress test to use and I end up using Intel burn test straight away, then do intel burn test again 20 times, then I use AIDA64 stress FPU & CPU only 15~20 minutes, then Prime95 v26.6 small FFTs for 15~20 minutes, and 10 cinebench R15 multi core runs, and 2 cinebench R15 single core runs. I've recently delidded my CPU which has helped me dramatically and has decreased my temps by a unbelieveable amount so that is definitely going to help me out when I'm reaching my high and stable OC.

my main issue is my BIOS settings. I have never really seemed to crack down on them and still don't fully understand all the options I have available.

Also what should I set my PCI latency timer to? 32? 64? 96? 128? the default is 32.

Is there anything here I should change to increase stability?

Is it weird that I can hit 4.6GHz at the same core frequency but to maintain stability I have to increase my Ring voltage instead of my Core Voltage? even when setting my ring ratio to auto and ring voltage to auto it suddenly becomes unstable? hence why I've stuck to 4.5GHz core & ring.
if you see anything in my bios that you think I should change let me know.

Thanks for reading.

Im getting the same sort of thing. My 4770k is stable at 4.5Ghz and thats it, none of settings i change in the BIOS make any difference at all which is annoyign as just with my Corsair H100x im getting full load temps of around 60 degrees. I think for me and I guess for you that it has reached its limit? going from 3.5 base clock to 4.5 and still being stable is no small thing so i guess we just have to accept it for what it is?

What were you aiming to get anyway? 4.7+???

sorry for extremely long reply, yes I was aiming for 4.7 but only managed to get 4.6GHz out of it in the end. on a different platform now.
