I haven’t encountered any stability issues in DCS, so far.
But I will do some testing and logging to check for heat issues, later.

Just curious but, aren’t CPU’s anymore going to auto-reduce performance/freq’s at any sign of trouble (stability) and temperature? Or just temperature.
They follow a built-in freq vs voltage curve and go up and down based on thermal and electric measurements. The increased power limit that I recommend, should be well within stable parameters, especially with proper cooling, and it is generally only when you tamper with the freq voltage curve that you get into stability issues.
I.e. setting freq too high or voltage too low to be stable.

Ah yes, you’re right! I was working with the PBO settings in the AI Tweaker (I was afraid to go into the overclocking section of the advanced tab). I turned the AI Tweaker settings back to Auto and turned the Advanced Motherboard whatever setting on and saw a slight decrease in performance. I might go back to the AI Tweaker settings.
Me too, saw the message and decided “nah, not right now”. Maybe two years after purchase.
I have now run both. Seems stable…
Not quite sure what I should look for in terms of CPU performance, but I’m thinking that if the system is stable, all I need to know is the frametime I get in VR 
Indeed there are! I’m not sure what the difference is, but enabling PBO in the AI Tweaker works just fine. Enabling it under Advanced, does not… Go figure.
Not sure how this should be set up correctly?

Alright, I’m not going to mess with the Advanced “Overclocking” section. I’ll run default AI Tweaker settings first, do a benchmark, then run with PBO Enabled in the AI Tweaker and do another benchmark.
Also, @Troll, have you turned on Resizable BAR yet? It’s pretty dang cool and gives you a big performance boost in games that support it. Just go into Advanced/PCI Subsystem Settings and turn Above 4G Decoding to Enabled and Resize BAR Support to Auto.
I’ll edit this post once I have the results of the PBO.
EDIT:
Holy crap! This is my first benchmark WITHOUT PBO Enabled. I reset my BIOS to Optimized and just set my usual D.O.C.P. (XMP) for the RAM and Resizable BAR enabled and setting my CPU fan profile to Turbo …

Slightly less performance. I’m going to stick with PBO set to Auto. YMMV.

Be careful with auto overclocking settings in your bios.
Voltages tend to spike pretty badly.
I’d advise to take your time and learn how to manually overclock. It’s become much easier these days and lots of guides are available for pretty much every mainstream manufacturer and model.

I agree with you for traditional auto overclocking tools @Yassy. But these are no auto overclocking tools, though I understand it sounds like it. These are just the buttons we turn in the motherboard to overclock Ryzen CPUs.
These CPUs really are a different story than the Intels from the past 10 years. They do not work at fixed voltage and clock at all like the Intels and are much more dynamic. (Intel Turbo Boost does not come close) Setting them to a fixed voltage and clock speed, a.k.a. the old manual overclocking, is a waste of energy.
This is the way to overclock them: by adjusting the power limits and if you want to go further, the curve along which they move.
“Auto” is just the default setting in the BIOS here.

Do you know why there are PBO settings in AI Tweaker and in Advanced?
I’m really puzzled by the fact that enabling PBO under advanced prevents my system to even post, but enabling PBO in AI Tweaker is fine…?
I now have it running with PBO enabled in AI Tweaker and PBO set to advanced with limits to motherboard in the Advanced BIOS settings…
Can’t set PBO to Advanced with motherboard limits in the AI Tweaker, BTW.
Don’t understand why they did this.
@Freak I have no experience with AMD, as such it was a general caution as it seemed to me some users above were in the ‘hmm let’s see what this does’ mode. That can be pretty hazardous to your mobo’s health.
Intels do not run at fixed voltages either. Even though many people set a ‘fixed’ VCore this does not mean its the only value used. Depending on powerlimits set VCore rises and drops with load and unload on the CPU.
Furthermore ‘Auto’ mode is standard on most Intel boards’ BIOS as well. This does result in nasty spiking however.
AMD surely will have a max voltage limit and my point was that using Auto might get you uncomfortably close to these limits.
YMMV of course and as said above, I have no experience with AMD.
But its common sense to not just ‘flick switches’ in your BIOS without knowing what the implications are, regardless of manufacturer.
It would be a shame to fry your new board, would it not? Or at the least introduce nasty instability.
Anyway, not trying to be a party pooper or doubt people’s senses and knowledge at all. Just a general warning as indicated above. F-ing about in your BIOS can result in unwanted system behaviour or damage over time.
That’s a fair warning and very true of older CPUs but as @Freak explained, the modern AMD processors are very different in that regard. They run almost at their maximum anyway and unless you go liquid nitrogen (which is obviously not suitable for everyday use) you’re only going to achieve comparatively small improvements by tweaking the boost frequency. The 5900X for example is designed and advertised with a 4.8GHz max boost but usually goes higher on its own without any tweaks. It’s just what AMD guarantees it will do.
If you tweak it you might even be able to push it past 5GHz but these are small improvements. Mine goes to 4.95GHz without any tweaks.

That plus higher clock does not always equal higher performance.
Either the load does not care or the CPU becomes less efficient due to other technical implications. Core clock rate is only one in the many things impacting modern PC performance.
I just don’t hassle the Hoff any longer. Ain’t nobody got time for that. I tweak the thermals until I’m satisfied with my foot-warmer and switch on DOCP/XMP.

I play strictly DCS and MSFS, MSFS currently sits around 40FPS on mostly high settings in 2D, VR with low settings is pretty stuttery. DCS in 2D I can run max settings at 80+ FPS regardless of location, in VR with a mixmaster of settings (High textures, no AA for example) I sit at a smooth 36 everywhere except for down low on Marianas.
For an off-the-shelf laptop that I picked up at Best Buy (open box and fairly cheap, at that) I’m super happy with it. I don’t expect it to last long term due to the heat it generates, so I plan to build over time a desktop as parts come more available.
Edit - taking a look at the results compared to the last one I did, the SSD is working pretty slowly. As DCS and MSFS sprawl, the 1TB SSD is slowing down. I’ll probably throw in another TB M2.0 drive and migrate DCS to that.

6yo build, most importantly it can play dcs and msfs2020 at 1080 p !
edit: hmmm maybe I should change the hdds… they are getting a bit old!
Sold my 3900x for $350 today. It was two years old. Bought and love my new 5800x for $600 (tax included). $250 for an upgrade that brings me back to 2021? This is unheard of.
