1.475V for Ryzen 5 3600?

[lafrente]

I got MSI board and Ryzen 5 3600. I am checking the volts with HWmonitor. Under "max" column I always see all cores have at some point jumped to 1.475 volts even when just browsing. That looks too much even if its momentary spikes. All cores easily hit 4.2 at the moment.

 

What is the fastest way I can get this to 1.375? I am positive I'll have similar performance with better thermals and longer life for the cpu.

You could try messing with a core voltage offset in the BIOS.

As a single jump in voltage, it's not so bad. If you were running that 24/7 it would be worse.

I'd imagine a small undervolt would be fine, but it would have to be small to avoid clock stretching.  And in order to determine if you've gone too far and the CPU is clock stretching then you'll need to run a benchmark to measure performance as clocks will still show regular speeds.  

 

As far as those highs -- they look normal.  They are instances of shorter single core speeds.

 

Lastly, use HWiNFO and not HWmonitor.

What is the cpu voltage under full load?

[Master Disaster]

1) Update the BIOS to the latest version

2) Manually download and install the latest AMD chipset driver from amd.com

3) Only use Ryzen Master to monitor your system.

 

These should help with voltage spikes, especially while the system is idle.

Couple minutes after running hwinfo I got 1.469V on all cores.

I don't know, I don't stress test my cpu. What would you recommend for testing?

First two I got done almost immediately after buikding the PC. Hwinfo and hwmonitor shows pretty much the same voltages. I doubt Ryzen Master would tell me something whole lot different.

Grab CPU-Z and Cinebench r15.

Have you updated the BIOS within the last month? If not then theres a new AGESA update out which deals with high voltage spikes. Same with Chipset too, the latest one adds a new Windows Power profile designed to stop the Vcore from spiking, it was released in November IIRC.

 

AMD recommend using only Ryzen Master to monitor 3rd gen Ryzen as other monitoring apps tends to stop the CPU from idling by polling it to often, this messes with the results and gives the impression the system is using more volts than it actually is.

I built the system yesterday and downloaded & updated bios. I'll dl Ryzen Master

Fair enough then, you're 100% good on BIOS & drivers.

I did "stress CPU" with CPU-Z and got 1.320V max on every core and 3.9 Ghz on all cores. Max temp was 80C

Edit: Right after I stop the test, I see random cores jumping up to 1.475V every few miliseconds.

The real take-away here is: those voltages are fine.

Good news! Your voltages are perfectly fine, this is how XFR works on Zen 2. High voltages and clocks during quick/light tasks and lower voltages and clocks during extended/heavy tasks. As long as your per core voltages drop below 1.325v under a sustained heavy load like cinebenche your're golden.

[glenalz81]

Yeah, all seems good.

If you don't have anything overclocked, I wouldn't worry about it. CPU's are made with longevity in mind. They usually get too slow before they die from anything.

I used my last laptop for 10 years, around 50.000 hours total on time so I wanted to make sure to get the same reliable performance.  And it is still perfectly fine to use today as long as you have an SSD & don't bloat your system with stuff.

That's good to know, thanks for the info.
