So ive been trying to get my new 3900xt to more often go past 4.3ghz mark and as ive been digging into this i decided to ignore the overclocking aspect and focus on what people say is a big issue with voltages and these cpu's. Somtimes a few cores will 4.6ghz mark. Im hitting 1.5v and according to hwinfo at max and im hitting an average of 1.46v. Ive seen forum posts all over place people claiming that anything about 1.35v is dangerous. Ive tried to reduce the cpu offset by 0.5v from the research Ive done.

As for getting higher clock speeds Ive tried different LLC settings and PBO settings tried ryzen master in oc nothing really changes. When underload i hit 4.0ghz mark with high voltages. I use a water cooler https://www.corsair.com/us/en/Categories/Products/Liquid-Cooling/iCUE-RGB-PRO-XT-Coolers/p/CW-9060043-WW

Where can i find my max voltage in the bios or set a limit on voltages? I have strong feeling if i can reduce the voltages this will lead to the high clock speeds. Ive attached related bios images and hw info ones. Also what are the consequences of ignoring this and how long will my cpu last if i do?

Linked photos of pbs/llc settings i tried from a guide ( i tried auto too), hw info and general bios settings.

Specs as requested
Ryzen 3900xt water cooled
G.skill trident z 3600mhz 16-19-19-36
Gigabyte x570 gaming x
Vega 64 Asus freesync@1440p 144hz

Is that first image taken while running a benchmark?
If yes: I noticed that the Power Reporting Deviation is high. That would mean your mobo's default settings are part of the problem.
You see, some boards have their default settings tweaked out of the box, deviating from AMD's guidelines for stock performance. It's just the usual rat race from the vendors trying to one-up each other in performance metrics.
You, as the end user, get screwed with a cpu that runs hotter than it needs to. Fret not, there are ways around this:
A)Update the bios. Some vendors added updates that removed the 'performance enhancements' - after enough complaints were made.
B)PBO has multiple levels. Simply enable it and run it at the lowest level.
C)If your board has PBO enabled by default, simply disable it.

If the first image wasn't taken while running a benchmark, then I suggest doing so, as it greatly increases the accuracy of the Power Reporting Deviation reading.

To answer the question in the thread title: It is fine, as long as it isn't sitting there.

If Im not mistaked a CPU package power and CPU PPT at around 53Watts would indicate a load on the CPU, but only a light one, since max PPT for that CPU is around 142 watts. Nothing like runing a multicore CB R20 to check that Deviation thing.

No OC and negative 0.1v offset works perfectly fine for my 3900X. Stable, nice temps, and the boost speeds are quite nice as it is (even on multi core) and it benchmarks very well

I found that worked for me too went from 7050 on cinebench to 7180 however single core performace went down. I also noticed more frame lag during intense moments in gaming. Might be i need a better gpu for 1440p gaming.
