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

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
 
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?
 
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:

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?

Right ok, what I do is disabled xmp profile on D.C.O.P and leave everything on auto default with stock speed and see how it goes, if the pc does shutdown again then I have to RMA to overclockers possible to sent back memory ram but strange as I did memtest86 v9.0 and ran it overnight with xmp profile enabled and it all PASSED with no issues.

Here is image below with xmp profile disabled as it ran at 2666MHz instead of 3600MHz but strange why the highest core clock still below 4400MHz as it only max out at 4391.7MHz?

Should I be worry about power reporting deviation below (showing red)

I put memory at 3600MHz and set dram voltage at 1.350v and all on auto by default but I know memory timing isn't great. That's the only start off to see if pc are stable without shutdown itself.

The SV12 TFN still in higher maximum voltage at 5.19v Should I be worry about this one? Does other got the same as this?

Shutdown at idle only when memory xmp profile is enabled. But I am now revert to stock memory but leave it at 3600MHz and hopefully it shouldn't shutdown itself. But shame about timing is not great on stock.

I have now raise this with overclockers in technical support and have to wait what they think of shutdown issues coming from?
 
This shouldn't have happen to stock amd cpu with all on auto default and should be stable. If it isn't then I might have to sent everything back for full refunded. This isn't acceptable in my view.
 
This is stock speed and pc has showdown again. I think I will sent it all back for full refunded. Not happy at all. I am well over 28 days DSR for full refunded but worry that overclockers might refused RMA for fully refunded for all parts returned under DSR?
 
Here is result of stock valves

Single core running cinebench R23

Multi cores running cinebench R23

Are these look ok?

Other thing is when I go to bios, enabled D.O.C.P a warning message appear on my screen below for 3600MHz XMP Profile enabled:

And under windows hardware errors kept climbing up before pc shutdown itself on idle stock speed.

If you bought an entire working system then ocuk owes you an entire working system

But if you bought a bunch of parts and don't know which part isn't working then I expect ocuk would only want to refund the part which isn't working if you're past DSR period.

You may want to call or message them to find out for sure or if they can help narrowing down what part is a problem.

Yeah this will pretty upsets me cos I paid lot of money for parts £980! I expecting everything should work as is it. Not happy at all. My last Intel Build PC i7 2700K work perfect straight from all the parts from overclockers 12-13 years ago.Never has any issues for 12-13 years and still ongoing strong.

I feel gutted now and regret now should have gone to Intel instead. 10700K

Soc voltage. Try 1.15v then 1.2v
This should stabilise the memory
Click to expand...

I did try both 1.15v and 1.20v both get windows hardware errors make no different at all. I think after running Memtest86 overnight was passed but try memtest64 within windows and pc crashes after running for 1 hour 17 minutes possible memory ram issues?

Can anyone advise me which memory ram are the best stable one for low cas for AMD 3700X for 2 x 8GB total 16GB (3600MHz) from overclockers store to replaced my faulty ram?

Maybe I should go for this one: https://www.overclockers.co.uk/team...3600mhz-dual-channel-kit-black-my-001-8p.html
