vcore too high on 5900x with Dark Hero?

[SonnyMarrow]

Just finished my new setup, and I'm concerned with the CPU voltage and constant fan ramp up.

 

Asus Dark Hero

5900x

3600 CL16 Crucial Ballistix

 

Using the latest bios, HWMonitor v.1.43.0 shows all cores hitting 1.500 V repeatedly while doing simple tasks such as Chrome browsing.

 

I have not changed any BIOS settings other than enabling DOCP (X.M.P. thing to set the RAM speed and timings).

HWMonitor also reports some cores reaching 4949 MHz, with the lowest core being 4599 MHz (the max column).

Is there a Zen 3 tuning guide for Asus mobos like the Dark Hero? I have both AI Suite and Ryzen Master installed.

My ASRock board does the same thing with my 3900x. It wants a constant 1.4v, which bumps up to 1.48v.

 

I manually set mine to 1.25v.

 

The SoC was also running at close to 1.2v constantly, under load and idle.

 

I used Jayz video about CPU voltage to set everything semi-properly, with VCore locked to 1.25v, SoC locked to 1.05v, and the... Uh, there's three other voltages that my board wanted to run away with. >_>

if i remember correctly, most motherboards will pump auto voltage into the cpu and its generally really high especially for what it really needs.  All you have to do is manually put in the voltage in the bios.  as for the different core speeds, all cpus do that.  Unless you lock the cores like i did on my 2600x they will all fluctuate at different speeds depending on which core is being used.

Thank you for the response. I will try manually setting the voltage. I thought that might force it to a constant voltage which is why I hesitated. And I know cores can do that, I was adding that in to make sure those speeds were normal with the voltage and temps.

You could use negative offset voltage, that comes at the cost of performance even if clock speeds look the same.
