Hello everybody. I have an intel core i7 2600K and ASRock P67 Pro3 MB. And i decided that I would overclock.
Now im not a computer noob but im not the best with stuff in the bios. I already did a small overclock. Im just gonna list my problem.
For some reason the clock wont go past 42 (ALL CORE). I put 43 44.... it goes back down to 42.
I read somewhere that you have to disable intels turbo boost rechnology to get past 3.9ghz which makes sense
because i have an overcloking tool that i use only for moitoring and it shows that the CPU speed doesnt go past 3.88ghz.
Im gonna post all the setting i have in the bios and i hope some people could help me out. BTW im trying to overclock to 4.3-4.6 for FSX.

Try this guide http://www.overclock.net/t/1198504/complete-overclockin...

I used the setting he recommends and am running 4.8 MHz at ~1.328 vcore

Your motherboard BIOS should have preset overclock settings that would work too, but those suck and usually give way more voltage than necessary. You could try loading up one of the presets for 4.5 or whatever and just dropping the "Additional Turbo voltage" by a ton
