AMD Ryzen 3700x stock cpu core voltage very high

I was bit worry as I can see CPU Core Voltage (SV12 TFN) under HWiNFO64 v7.02-4430 sensor status was minimum 1.362V maximum 1.519V

Should I worry about this?

Does seem a bit high as normally it won't go over 1.5v

Is this at stock settings?

Yes it stock setting all on auto default. The pc has shutdown itself (first time happen since brought all parts from overclockers March 15th 2021) scary now

Got a 3800xt and msi b550 carbon my range is 0.919-1.5v its not terribly far out, more interested in your minimum voltage you got a lot of background programs running? using ryzen power plan? should drop below 1v at idle
 
I knew this sounded familiar.

Because I replied when you posted it last month.

One very brief check aaand: https://www.overclockers.co.uk/forums/threads/amd-ryzen-high-vcore-voltage.18924510/

Read the entire post from Robert @ AMD technical marketing about the 3000 cpus:

and this quote in particular:

It is perfectly okay if your CPU is periodically using 1.4-1.5V to achieve boost frequencies, and you should see dips into sub-1.0V as the CPU goes into idle.

My motherboard is B550 Asus Tuf Gaming Plus with bios version 1202 as it was come out of the box.

My pc was suddenly shutdown twice now and turn back on itself. I have ran memory test overnight as it passed with no issues. Was it caused by gtx graphic card or power supply as my power supply was bequiet straight 11 gold plus 750W.

The higher cpu core voltage sv12 tfn so far was 1.529v what is going on with my amd stock processor as why it went over 1.5v.

Do you think I should RMA back to overclockers as I brought it March 15th 2021 online purchase
 
looks like your board has a update Version 2201 date 2021/04/09 so you could try a bios update to see if it helps lower the voltages , also do you have the latest chip-set drivers ?

or you could contact overclockers support and see what they say
 
I am not upgraded bios no way. Because once you done that, you can't revert or downgrade back if become unstable with beta bios 2201. I stick with the bios version that come with the box. I will message overclockers on monday that I am not happy with processor idle stock over 1.5v. I have to set manual vcore at 1.20v for all ratios at 40x (it will not boot up if I put 44x)

How to tell if chipset driver from device manager are latest one please?
 
i would look in add and remove programs and the chipset driver package will show , the latest from amd is 2.13.27.501 if you installed direct from amd site it will show

totally understand the bios sorry did not realise it was a beta :eek:
 
yes found it got amd chipset driver v 2.13.27.501 and GTX 1050 TI driver 466.11 already installed on my pc just now.

Ran on all on auto default in Bios.

Windows Hardware Errors (WHEA)
total errors 7
machine check errors (AMD64 NB) 7

CPU Core Voltage (SV12 TFN) still on 1.519v as maximum :mad:

PC shutdown itself again and turn back on itself. Sound like faulty AMD CPU Processor?

The chances of you getting a faulty CPU are so small as to not even be worth considering unless you've exhausted literally every other possibility. You seem fixated on the idea that the CPU is at fault and conflating the voltage issue you perceive as existing with the problems you're actually having, but if there is a fault with something, it's several orders of magnitude more likely to be literally any other component, such as the RAM, PSU or motherboard.

Incidentally, it's the motherboard that's responsible for pushing voltages over 1.5V. Even in your own screenshots the max VID (i.e. what the CPU is actually asking the motherboard for) is 1.494V, which is perfectly normal for a Zen 2/3 chip under light workloads. The motherboard is then adding another 20mV to that for whatever reason. At least maybe it is, since software voltage readings are inaccurate at the best of times anyway. But even then, a 20mV overvolt isn't going to be causing your system to crash unless you hit a thermal limit.
 
I have update Bios to the last stable bios v2006 just now. Hopefully it won't shutdown pc this time.

I check the CPU Core Voltage (SV12 TFN) still on 1.519v as maximum value but run at 1.256v during cinebench R23 multi core load. (does anyone on AMD 3700X have that on stock speed 3.6GHz up to 4.4GHz all on auto default)

Your voltages are perfectly fine.
Its current not voltage that kills a cpu and spiking at 1.5v for small periods is what my 3900x does as well.
Your instability is most likely a ram issue.
Are you using a xmp profile?
