Hi i have an i5 3570k and i am trying to overclock it, i have adequate cooling and the system is completely stable however when i try to adjust the max OC on all cores it simply reverts back to 4.2ghz. I get no errors no indication as to what is wrong and i have reset my bios and made sure they are running the most recent firmware (v2.90) I learned that "Advanced Turbo 30" must be disabled but i simply don't have that option :< seems like it was an option only for version 2.80

I am a pretty big noob when it comes to overclocking but i thought it was simply increases speeds and making sure it runs stable under a burn test right?
