CPU overvoltage error need help ASAP

Specs: Windows 10, AMD FX-8320E
Hello guys

I will start by apologizing for any mistake i make while I'm writing down my question since i know little to nothing about CPUs , voltages , and overclocking in general.At the most , i know overclocking is something you should not mess with if you dont know what you are doing.
Lets start

Specs
OS:Windows 10 64 bit
CPU:AMD FX8320e 3.2 ghz eight core
GPU:AMD Radeon (TM) R9 380 4gb
PSU:SeaSonic M12II 620 Bronze 620W
RAM:HyperX 8gb GDDR3 (1 dim)
Motherboard:Asus M5A78L-MLE USB3


So, i started getting a CPU overvoltage error again , while playing Arma 2 and Arma 3.
I used to have it in the past but i though it was because of a s--- PSU i used to have (Nox URANO VX 750w), i replaced it with the seasonic one meantioned above and it stopped happenning, untill today.
After googling the issue i didnt find any solutions that could help me, i did find some stuff about manually setting the voltage on my BIOS,but for that i had to know a lot of info that i didnt fully have access to mainly because you have to set it according to the frequency your CPU is running at.
I downloaded a few programs like core temp and AMD overdrive since they let me see some of the values i need.
This is where it gets confusing for me.

Im looking at Clock/Voltage tab in amd overdrive and target speed is 3200mhz , while the current speed of all the cores varies from 3500 to around 4018.Doesnt that mean that my cpu is being overclocked?

I was hoping someone could help me with this because as i said , i know little to nothing about CPUs, i'm willing to fully cooperate with whoever wants to help me with this with screenshots and other important information as well.

Thanks in advance!

The FX8320e automatically overclocks up to 4.0GHz based on load using "Turbo Core Technology". It also underclocks when under a light load. The CPU voltage automatically changes (either up or down) along with changes in the CPU clock speed.

https://en.wikipedia.org/wiki/AMD_T...

Here's the power states for your CPU:

Turbo:
#1: 4000 MHz, 1.4125V
#2: 3500 MHz, 1.225V

Lower power:
#1: 2800 MHz, 1.075V
#2: 2300 MHz, 1V
#3: 1800 MHz, 0.925V
#4: 1400 MHz, 0.8375V

Make sure you have the latest BIOS version for your board - 0501.

M5A78L-M LE/USB3 BIOS 0501 - direct download

EDIT: I noticed you only have one stick of RAM. You should have 2 so dual channel mode is enabled. It should also be DDR3-1866 or better. Slower RAM and/or single channel mode will work, but your system will take a performance hit.

Also, in your other thread from several months ago, you gave a different model number for your board. This time you included "USB3" which means the BIOS version is totally different. That explains why it wouldn't update to version 1601.

Yeah i ended up finding about th USB 3 by myself and managed to update it.Didnt change anything though
SO based on what you said, what would you advise me to do?
I play video games so i would have the lowest downgrade in cpu speed possible

It's hard to draw any conclusions about your situation when you don't specify what's giving you these alarms, nor the voltage that's triggering these alarms from nebulous sources.

WHat would you need to know ? like i said i dont have any problems with supplying you guys with the tools to help me xD.
Maybe a screenshot from overdrive ?

Pretty much what I just said you were missing. Namely, the program reporting the over voltages, and the voltages that are throwing it into a tizzy.

What program can i use to record the voltages?

By the way i just remembered , i enabled cpu virtualization over on BIOS a while back to play an android game on Memu emulator , and i think the cpu overvoltage error started happening after that.Just now i was playing on my emulator and watching a youtube video and my pc shutdown by itself out of nowhere, but this time i didnt get the overvoltage error when i powered it back up.Weird

What, your monitoring software doesn't tell you what the voltages are? "You're over voltage! No, you don't need to know what the voltage is, just trust me, it's too much."

Here is the error i get , as you can see the voltage that made the pc shutdown is not there .That is precisely why i asked if there was any program that could record voltages in real time and put them on logs , so that when i turn my pc back on , i could see what the last voltage being fed to my cpu was .

Oh, it's the BIOS reporting the error. Okay, PSU's probably bad.

No it isnt , its pretty much new ,i already replaced the other s---ty one i had before this one ,and i even sent it to be repaired,they didnt find anything wrong with it.
I said that when i oppened the post

Only two things control voltage to the CPU. They are the MB and the PSU. The MB is saying it cannot do its job. If you're sure it's not the PSU, and I'm not sure how you can tell without testing, then it must be the MB.

This assumes, of course, that the power going into the system isn't dirty. If it is, get a power conditioner or high quality UPS.

like i told you many times already , i replaced the psu .The old one gave me this problem as well , i even sent it to get repaired and they didnt find any problems with it.This one is new.You dont need to test it to do the math on why it isnt the psu's problem.

I spoke with my cousin a few days ago and he said that given that i have an asus motherboard , i should be able to manually lower the voltage on the BIOS , but looking at all the values that are there , i have no idea what i should lower or not

A post on overclocking your CPU that includes info on VCore (CPU voltage):
http://www.overclock.net/t/1560467/...
I do not know AMD well but some motherboards increase the vcore under load and that may be your issue. You can try resetting the BIOS to defaults and then making sure your date, time, CPU info, memory, graphics (onboard or PCIe), boot devices, and boot order are set. You can try changing the vcore from auto to manual and locking it down to what it shows currently at idle or the lower end of what was listed on the post (1.25V) but certainly stay below the recommended overclock voltages shown. If you become unstable at the locked down voltage you then raise it by 0.01 at a time until it is stable under full load. Always keep an eye on the temperatures when changing the clock or voltage so keep HWMonitor open when evaluating the stability under load. Your mat temp is 61C which you do not want to reach, your idle should be in the high 20C or low 30C and your load temps should be in the 30C to low 40C's. If your temps are high then you need to remove the CPU heat sink, clean off the thermal compound with rubbing alcohol and reset it with the proper amount of new compound (see link on the proper method for your CPU).

If you still have heat issues then we need to address the case cooling or possibly a better heat sink.

You have to be a little bit crazy to keep you from going insane.
