I cant ocing ... I dont know what happens , i update the bios to the latest , but when i set voltage , core speed , etc , i save changes , enter windows and the 8600k is still in 3.6ghz , then i restart the PC , enter BIOS and all the options are undone ( but in CPU-Z says that the cpu is a3.6ghz but the voltage that i set in BIOS , windows took perfect ) ...
So i dont know what is the matter right now , all the options save , except the cpu speed
