Concern about CPU voltages

[martymarty004]

Hello,

After a year since I built my PC, I decided to update my MOBO (MSI MPG B550 GAMING PLUS) to the latest stable BIOS (7C56v1A).

 

I read that my CPU (Ryzen 7 3700X) doesn't work well on OC, so I didn't bother manually searching for the perfect parameters, and I left all the work to PBO and Game Boost, and they managed to raise the clock to about 4.30GHz.

After the update I had to reconfigure the UEFI settings (XMP, Wake on LAN, SVM, etc.), but everything seems to be running smoothly, and plugging in USB drives seems more responsive than ever.

 

The only things that concern me are the voltages that HWiNFO reports when the PC is idle, which I think are a bit too extreme.

 

I run a test with Cinebench R3 (30 mins) to check the stability of the system, and these are the results:

 

- After 25 mins of testing:

- After 5 mins of idling

When the PC is working at full load, everything looks fine, even the temperatures are kept stable by the AIO (ARCTIC Liquid Freezer II 240). It's when the PC is idle that the voltages are a bit extreme.

 

If these voltages are really too high, is there anything I can do to prevent my MOBO from frying my CPU without removing the boost? (If you suggest manual overclocking, I can try that, but I am no expert at all and I will need your help).

 

 

 

Information about my PC:

• OS - Windows 11 x64
• CPU - Ryzen 7 3700X
• RAM - 4 x 8GB Crucial Ballistix @ 3600 MHz CL16
• GPU - AMD Radeon RX 570 OC
• MOBO - MSI MPG B550 GAMING PLUS 
• Power Supply - Seasonic FOCUS GX-750W 80Plus
• Cooling - AIO ARCTIC Liquid Freezer II 240

Its normal for the cpu to boost really high on idle to make your pc feel snappier, it doesnt do this on all cores ofc so you are fine since it seems like current is the main thing that degrades your cpu

My 3700x does the same, it really likes to give one core 1.5v while the others sleep for some reason. Doesn’t really degrade too much, it’s exactly in the safe specifications.

It's perfectly fine.. Ryzen CPU's often report high voltage at the bios level or when idle.. It's all within spec.... Just because the CPU may or may not be getting X amount of voltage at idle, doesn't translate to real world usage... I can dump stupid voltage into X CPU, but if it's not being used it doesn't matter. I have an MSI MEG Unify that shows high average CPU voltage in the bios, but once in windows it's perfectly fine.

 

Think of it this way.. The bios has preloaded the CPU with X voltage.. The CPU will only use what it needs and performance and heat output will reflect that.... You can't "force" voltage into a modern CPU.. It's not like overvolting an old P2 or K6-2
