Here are some common settings for your Ryzen 3900XT manual voltages.
I'm brand new to this CPU and just trying to get a feel for it, so I wanted some info on what others are getting with the 3900xt and manually overclocking. So I tried pushing 4.4ghz @ 1.32v with LLC2 for gaming while playing CoD. The temps never got above 63 (with occasional spikes to 67). I ran Cinebench R20 and scored 7848, but the temp did hit 80 which isn't too bad I don't think for that test. Idles at 37 degrees (it idled at 33 degrees with it all on auto). No idea if any of this is good or bad, or if that R20 Cinebench score is good nor bad as well. I don't leave this pc on 24/7 and all I do is game (CoD/WoW mostly) so my question is 1.32v for gaming safe for daily use?

I don't know much about speed tricks, but if you stay steady on 4.4GHz while using 1.32 volts, then you're a winner.
I would suggest turning off the overclocking and just using PBO instead with those values. It will boost you past 4.4GHz even if not all cores are running (so benchmarks run on fewer cores), which means gaming performance can go higher than expected from a fixed speed at 1.32V. Also, the voltage gets controlled by sensors rather than being stuck at a set number, so your CPU lasts longer. Your numbers match what I ended up getting with my own tests, but in the end it wasn't worth doing for gaming. Other people even say any constant voltage above 1.2V can damage the chip over time. You can check the Cinebench settings to turn off cores and see if your speed jumps up like that from a single core test. Also keep in mind Cinebench starts low priority by default, so turning it on higher could show you how fast things really are when they get heavy.
Any high-speed overclock is dangerous if done without checking the specific settings first. A 1.32-volt setting isn't super low when the chip often needs to drop down to 1.275 or even lower just to stay safe while doing a lot of work. I wouldn't want to keep it like that for long, especially on an 'XT' processor which is top-notch and made from mature chips. That's why you pay extra for it—to get the best boost speeds at lower voltages. I agree with you, so don't just set a fixed voltage instead of using PBO (Power Boost Offloader). Let PBO handle the heavy lifting in games and other light tasks to keep your processor running smoothly and safely.
That's why I tried manual overclocking. Before, my CPU wouldn't go above 4.2 ghz when PBO was on, even with everything maxed out. When I tested Cinebench, it hit 3.96 ghz. But while playing Call of Duty, it reached 4.23 ghz. The real problem is the voltages were too high at 1.38v because PBO was managing them. Even though I set the initial voltage to 1.32v for a theoretical 4.4ghz speed, that's not enough right now. I need to try more tests and slowly lower those voltages if possible. My aim is to get down to at least 1.24-1.28v so the CPU can run at a minimum of 4.3 ghz. If I still can't reach that speed, then I'll just leave PBO alone and let it handle things naturally.
That's why drea pointed this out - checking voltages while doing PBO can be totally misleading because they often end up between 1.35 and even 1.4+ volts, sometimes higher. The real thing is when you actually need lower voltage, it definitely drops that way. Your numbers look wrong though - I re-tested them with my current settings and the results go as high as 4.45 on one thread, 4.3 with four threads, and about 4.05 for all cores combined (I'm pretty sure I did tests a few days ago where it was 4.2 in single thread and 4.55 in single thread, maybe I changed some settings along the way). No matter what you end up doing at the very end with your final overclocking, it won't go much higher than PBO can boost on its own anyway, and that means giving up some safety too. It's your choice in the end, but we're talking about areas where the changes are tiny (even if there might be a small performance bump in certain games) so it really isn't worth it.
Not really quiet. For tiny things like opening the browser or explorer, I saw it hit 4.6 gigahertz sometimes. That's nothing because my main job is gaming, and before that I said it never went over 4.23 gigahertz while playing games. You'd technically be right if they were boosting to 4.7 gigahertz when gaming, but that just doesn't happen.
Have you updated your chip and BIOS programs? Why does your computer run at 4000 megahertz speed for RAM?
