Unstable voltage on Am3+ Setup

[Guarho]

I'm having a trouble with my voltage, mainly when i start a game or reach certain cpu usage point
The voltage goes down as well the clock speed (using HWinfo i noticed it)
And using Afterburner i know those drop spikes are each 30 secs (Yeah don't know why the temp read broke at the same time)

Spoiler

Anyways it's just that not a single boot or shutdown problem, only performance issues, so what could be the problem?
CPU damaged, mobo configuration, psu damaged or mobo damaged?
This are my specs

Spoiler

- Win 10 64 Bits
- PSU: 550 Watts Bronze+ Coolermaster
- MOBO: Asus m5a78l-m lx plus - Updated to 1701 Lastest version
- CPU: AMD FX-8350 (Not OC)
- RAM: Dual stick (4+8gbs 1600mhz)
- GPU: Nvidia GeForce GTX 1660 Super

This are the mobo settings:
On the JumperFree it's everything in Auto, i should change something there?

Someone can help? Thanks in advance (Sorry if something it's misspelled, non english speaker)

I missed some valuable info about this problem?
