I assume your CPU is the 4670K and not the Ivy processor that the 3 denotes.
🙂Please do this.
Clear CMOS
XMP profile as mode of OC in bios.
Multiplyer to 40 for all cores syncronised.
Vcore to 1.2625
F10 and enter.
Does your system boot to OS?
If yes reboot and set multi to 41, repeat until you are no longer able to boot into OS.
I would suggest that for 4.4GHz you going to need a bit more than 1.2 my friend. Most CPU's will need about 1.28 for 4.4GHz
