Ryzen default stock voltage spikes

[cchhrriiss]

Hi all, just installed a Ryzen 7 1800x on an Asus x370 F Strix replacing a 1600 I was using. I have been monitoring my hardware a little closer then usual since the install, and happen to notice CPU voltage spikes over 1.5v some creeping up to almost 1.6v. The voltage fluctuates constantly ranging from 1.2v to over 1.5v, which seems a bit hi to me. I am running everything at stock default settings with the exception of my ram being at 3200 CL14 at 1.35v which is what it is rated for, everything seems to be running 100% fine with CPU temp idling in the 40Cs and just going over 60C under load (using a Wraith Max to cool the CPU). Seeing these spikes i decided to do some research online and it seems this is common and is related to XFR, multiple people are saying it is harmless and since the spikes only last a second will not hurt anything. I guess I should be content with my online findings and not worry about it but I am concerned about degradation and the effects of this happening over a long period of time, and shortening the life of the processor which I aim to get a good 5ish years out of. Decided to make this post to see what you guys think about these voltage spikes, and if you feel it is cause for concern. Thanks.

Yes pretty common thing although my 1700x was reaching only 1.516v but voltages are very transient and short. Haven't detected any deterioration. Few days ago I switched to 2700x and getting same thing.

Thank you for the response, yes it seems common, I dont think anyone can really answer if it is causeing degradation with the platform only being 1 year old. It doesnt seem good in my opinion, AMD says max voltage should be what 1.4vish?, then has the chips spike well over 1.5v lol.

1.425 - 1.45v is what AMD says is maximum acceptable with proper cooling but that's for 24/7 OC on all cores. Even that is on conservative side, AMD just covering their asses. Good cooling and VRM and no problems.

I have this exact same issue. I watched a few videos and did some research on overclocking in general and something I did to the bios stabilized a 4.1 overclock on the 1600x. It never hit past 1.395v. However, if I default the bios and run stock 3.6ghz, it starts spiking from low 1.2's to high 1.4's (1.46).

A couple things I'm about to play with are the offset voltage, phase control, and switching frequency. I read somewhere that raising the switching frequency gives "cleaner" voltage, at the cost of slightly higher thermals on the vrm.

Maybe you guys can try some of these out and see how it goes.
