PC start up behavior on over-clock

I have my i7-4770K CPU running at a stable 4.4 GHz at 1.24 v. The same with the 2 cache ratios. I have noticed that since setting this, when starting the PC from a cold boot (I don't use sleep or hibernation), it powers up for a second, powers down and restarts again. I resume this is because the UEFI BIOS is adjusting the voltage for the over-clock? Is there a way to stop this happening. It is a minor issue but adds 1.5-2 seconds to the boot time, which is a bit ironic considering an over-clock is intended to speed things up.... Is this normal?

Hello

If this is after removing power from the system this is perfectly normal and is also required. If power has not been removed it points to instability during the boot process.

Thanks Praz, yes, this is after a cold reboot after a total power down and switch off at the wall socket.

Hello

You're welcome. Completely removing power results in the double boot so no issues with what you are seeing.
