Could be a motherboard limitation. But that is getting pretty close to where you should consider getting a better cooler anyway. 4.5Ghz is pretty damn good for an everyday overclock.
That's a "safe" limit that you can probably override from a jumper, DIP switch, or another BIOS setting. That being said, I recommend a max core voltage of 1.3V for .22nm Intel chips and 1.4V for .14nm Intel chips, so you're very close to the safe limit of your CPU already. Now that you know that, if you're still determined to raise the voltage, please tell us what motherboard you have so we can find out exactly how to do that.
That's a "safe" threshold you might adjust from a jumper, DIP switch, or BIOS option. Nonetheless, it's wise to aim for a max core voltage of 1.3V for .22nm Intel chips and 1.4V for .14nm Intel chips, which keeps you near your CPU's safe limit. If you still want to push the voltage higher, let us know your motherboard model so we can determine the best steps.
