4770k & z87 hd3 overclock
Hello, your 4770k was successfully overclocked to 4.3 with a voltage adjustment to 1.240. That voltage level seems appropriate for your setup. Regarding the second question, voltage can vary depending on the system configuration and components, so it doesn't always stay the same when overclocking.
I maintain my Vcore at 1.3875 (4.7 Core / 4.4 cache). During stress tests, it tends to rise slightly above that value.
CPU will lower its speed to 800 MHz when idle unless you disable Intel's power-saving options. In a game with around 8 programs running and voltage at 1.21 with BIOS set to 1.3875, this happens.
Voltage increases automatically by 0.10 to 0.13 above the BIOS setting when AVX instruction sets are available.

Yes, it is correct. Reading above 1.3 V on Haswell is harmful to the CPU.
Also one more question, will the voltage remain constant when the CPU is overclocked? That's what the CPU voltage offset mode in BIOS does. It will reduce the voltage back to idle just like the default settings (1.1v??) even if Vcore is set to 1.24v. I'm talking about ASUS boards specifically. I'm not sure how other manufacturers might describe this for similar purposes.
