Ryzen 3700X high core voltage and temperatures

[AleXileD]

Hello Forum users,
 

This weekend I built my new gaming system and started doing all driver installations.

After everything was installed i also installed HWINFO64 to check is all my speeds and temperaures were ok. All I did was apply the XMP profile for my RAM and other than that I left the system stock.

However now I noticed 3 things that concern me:

1) CPU temps and core voltages seem quite high? Reported voltages and temps are from playing 1 match of Apex Legends (running stock cooler)

2) Memory speed reported is only half of the XMP profile

3) HWINFO reports my CPU as an engineering sample (I bought it new from Amazon.de)

Check with Ryzen Master. There has been some missreporting on voltage. 

 

Besides, its XFR doing its thing. 

 

Temps are inline with what could be expected from a singlecore workload due to thermal density.

Also in Ryzen master the voltage seems quite high?

That's normal.

What is ? All 3 points?

This is normal with the Ryzen 3000 series. I have a 3700x as well and saw the exact same behavior. I personally did not feel comfortable with this so I manually set my cores to 4.2 all core at 1.35v. 1.35v is also the maximum recommended voltage by AMD themselves.

Voltage isnt applied to many cores and looks like typical XFR.

 

You are not the first one to look at this.

 

 

If you want to be 100% safe. Just update the BIOS once in while. Its still earlydays for Zen 2. So thats just good practise

To add, Here is a great video from Jayztwoccents explaining it all in detail, albeit with a 3900x but the same logic and principles would apply to the 3700x as well.

1) Ryzens boost algorithm is very agressive.
2) Ddr means double data rate. 1800x2 = 3600.
3) Software probably isn't optimized for zen 2, i wouldn't worry.

Amd said 1.325V for high current and 1.47V for low current, don't know where the 1.35V came from.

Thanks!
You make all the settings in the bios? Does that not fix all values to a specific value so the CPU cannot lower the voltage either?

I have never used Ryzen master before.

I personally do it in the BIOS.

I believe it was in a Reddit thread and came directly from AMD themselves. 99% sure that Jay references it in the video I linked as well if memory serves me correctly.
