I'm coming to you because I really don't know what to do, I'm completely lost. No matter what monitoring software I am using (HWinfo, CPUID Hardware Monitor, Ryzen Master) I am always recording unusually high vcores and temperatures values.

I'm using the AB350M PRO4 with a r5 1500x@stock frequencies and voltage.

Here's a sample of the voltages and temperatures I have been recording. And yes, this is actually 10Ghz...

So here I am... I have tried every single bios update you can see; I've tried to check every single thread on the internet but I couldn't find anything.

I need to mention that I did not overclock or change anything in the BIOS, everything is running at stock volatages and frequencies. Also the system is 100% stable, never had crash.

Regarding the temperature, it is very weird because I can see jumps from 30C to 55C in a fraction of a second before it goes back to 30C or 40C, and this happens when I'm not doing anything except maybe opening a new webpage.

Is it possible that this is simply a case of faulty voltages/temperature sensors in the motherboard ? If yes, can these faulty sensors also affect the frequencies that are displayed ?

I really need your help because I don't know where else I can get relevant information.

Thanks a lot !

When i launch prime95 i jump from 32° to 60° in 1 second.

So with a browser like chrome who is very multi-tread app, it's possible it you have a lot of tabs and extensions + anti-virus in real mode.

For the vcore, the auto-mode is very generous in voltage and can send 1.5V during a short moment. I suppose it's not too risky if constructor did it, as long as it is not permanent.

Yes I did install Ryzen Master and I observed a couple of very strange things.

1. It eats A LOT of CPU ressources. To give you an idea, my CPU usage is close to 1 or 2% with just google chrome, Opera, steam and Skype opened. It jumps all the way to 10-15% with Ryzen Master open and one of the threads is actually almost saturated (~90% usage). A the same time I see temps reaching 60C on Ryzen Master. And I mean I just got Ryzen Master open; i don't even try to tweak anything, I literally just have it open.

As soon as I close Ryzen Master everything goes back to normal, low CPU usage etc...

2. I downloaded the latest HWInfo version and after around ~10 minutes or so of light usage, the average Vcore voltage was still around 1.4 on average !

Now as SixPack mentionned it, it's normal for a CPU to have peaks around 1.5, but we're talking here about an average of 1.4 (when it should be around 1.3).

Once again when it comes to the system stability, my system is super stable, never had any throttling issues or anything, it's only these monitoring tools that are displaying those super high voltages.

@SixPack Alright if you got the same temp jumps then I assume there's no reason to get worried. Do you also see the same jumps when you open chrome ?

Yeah that 10Ghz is out of this world :D (especially @stock frequencies lol) That's one of the things that lead me to believe that there's an issue with my motherboard sensors !

Thanks !! I'll have a look at this during the week end !
