HELP! CPU Over Voltage Error

[Garethb]

Hi Everyone,

 

I'm having a big issue! I recently swapped out my PSU for a higher wattage and somewhere down the line I got a CPU Over Voltage error. I since went back to the old PSU and still have the same problem. CPU is at ~4v

A local IT company told me my CPU will most likely need to be replaced, but I just noticed the DRAM is also at ~4v. Do I need to replace the DRAM as well? Is this an issue with the motherboard? I'm looking at replacing whatever parts I need to, but now I'm wondering if I need to start over with a new build...

 

Specs:

MOBO: Asus Prime Z370-A

CPU: i7-8700K

RAM: G.SKILL Ripjaws V (2x16gb)

PSU Old: EVGA G2 650w

PSU New (returning): EVGA Supernova G5 1000w

GFX Card New (haven't tested yet): Gigabyte Aorus Master 3070ti

@Garethb If your CPU and memory were actually at 4V, they would already be dead.

 

Can you boot up into Windows? What does HWiNFO report?

I can only boot Windows if I ignore the voltage monitors in the BIOS

I disabled the voltage monitors in the BIOS and ran an HWiNFO report. Here's what I got. Looks like it's running between 0.6 and 1.2vish.

@Garethb Run Sensors only. Look for VCore voltage.
