I have an i5 6600k and an asrock fatal1ty z170 k4 motherboard. I have gotten the cpu to oc to a stable 4.4ghz when I use a fixed voltage of 1.275v. I want to run it as a 24/7 oc though, and I don't want to be sending 1.275v to it all the time. There is only the fixed and offset settings in the bios, and everytime I run the offset in any mode the windows crashes when I boot. Whenever I go back to the fixed voltage, it runs just fine. Is there any way to oc the cpu with an offset voltage setting to reduce the amount of volts sent to the cpu when it isn't under load, and if so how would I do this? Thank you in advance.
