Sorry for noob question
I'm trying to oc my 2500k with msi z77a g43a, and master cooler 212evo.
it works stably at 4.1 ghz and doesnt even reach 60*c underfull load after i changed cpu ratio to 41 with stock vcore voltage and intel turbo boost disabled.
but i don't know how to get it higher because the highest cpu ratio i can set in bios is 41. is my 2500k unlocked? If it works well, should i turn on the intel turbo boost or inrease vcore voltage a little bit?
Thanks and sorry for my English.

One of the main reasons I steer clear of the MSI motherboard is all the hoops you have to jump through just to manually overclock.

If you ever clicked on the ECO radio button in the BIOS you automatically set some features as unadjustable, so you will need to do a hard clearing of the CMOS settings using the motherboard jumper, that will return your motherboard to factory specs, make sure the computer is unplugged from the wall when you do the clearing and follow the instructions in your M/B manual.

To overclock you need to use the Standard Mode button and disable the Genie button it is about half way down your options and save and exit.

Now you should be able to manually overclock under the Standard Mode button, but whatever you do...

The rest is up to you.

Most reached 4.5ghz with the 2500K somewhere in the voltage range of 1.290v ~ 1.330v you'll have to find your voltage sweet spot in that CPU voltage range, start at 1.290v and progress from there, until you discover the voltage that will support your 2500K at a 45x multiplier.

Good Luck to You! :)
