decided to oc my i5 4670k

Hello guys,
I decided to oc my cpu. I'm currently reading here and there. I haven't touch anything and while loading the bios I saw some strange numbers. While everything is at stock and the cpu frequence multiplier is at 32 my vcore is at 1.320v but in cpu status I get 4.3 cpu frequency. I run an aida64 test and I get 4.3 frequency at 1.306v vcore and normal temperatures at 63 in 5 min test. What should I do? leave it as it is? try to oc?

My system:
cpu: i5 4670K
motherboard: gigabyte z87x-oc

That's already overclocked. 3.8Ghz is the normal max.

Yeah but how is it already overclocked? I recently formated my windows and upgraded to windows 10. I didn't do it myself cause I was getting bsod with no reason, but nobody did it as I know. And now on auto (default) bios settings and everything I get these numbers. confused

Don't know. Any overclock will be saved in the BIOS so its possible software prior to your format did the overclock.
