Overclocking help

[Arsonist]

Hello.

 

I have a problem with my cpu overclocking. I set to XMP, Sync all cores, set multiplier to 45 and so on. But the problem starts when i set my core voltage to manual mode and set it to for example 1.280 V. When i run Prime95 for stability my core voltage jumps up to 1.3V+ and it will not cap it like I set to in BIOS. Why is this happening? Is it because i should use other stress testing software or is it because i have my Windows power plan set to "High performance" and it delivers higher voltage to my CPU.

 

Basic specs:

 

CPU: i5 6600K

MOTHERBOARD: Asus Z170-A

RAM: Corsair Vengeance LED Blue

PSU:  EVGA 750W GQ Gold Plus

Modular

 

Thanks in advance.

I remember in a video that I watched someone said Prime95 was a very intense program that hit the CPU hard, perhaps this is what they were referring to, try another stress testing software and keep an eye on voltage while it runs.

 

hope this helps!
