Overclocking Intel Core i5-4670K Guide
My ASUS Z87-PRO supports Auto Voltage at 4000 MHz. I attempted 4200 MHz with 1.200 V, causing the computer to freeze in Prime95. At 4500 MHz, 1.2 to 1.3 V triggers a blue screen during Windows startup.
These only indicate that your overclock isn't stable. A value of 4500 might be challenging to achieve on a 4670k under 1.3v; you could attempt at least 1.350v, though that's not advised. Consider setting the voltage to 1.250v @ 4.2 and check for stability. If it becomes unstable, lower the voltage by 0.005v until stability returns, or increase the multiplier to 4.3 and test again if needed. Keep adjusting until you find a stable setting. Good luck!
