Lenovo 5 5800H undervolt?

Can't be done. Only thing that you can do is limit the CPU's TDP.

You can adjust the core using "core optimizer" within the AATU (AMD Tuning Utility) app. I tried it, it works, but nothing earth-shattering like traditional undervolting using XTU / Throttlestop. Your mileage may vary.

What does it do?

It supposedly automates an undervolt using the app but is still tied to AMD's algorithm and still not as good as a manual undervolt. I may be wrong, that's just what I've gathered from my brief reading about it. 

 

If your temps are too high for your liking the better approach is to use the tweaked power settings with Legion Toolkit or otherwise doing a minor registry edit. My CPU performance boost mode setting is set to "efficient aggressive" rather than "aggressive" or "enabled" and I never come close to thermal issues when gaming or with any other use (I normally don't do really any CPU intensive tasks).

I get +90ºC when i push the CPU to the max which is to be expected. I just wanted that undervolt would make that value a bit less.

 

You'd probably have better luck playing around with the maximum TDP. 35-40W seems to be the sweet spot between thermals and performance for Ryzen 5000+.

I checked HWiNFO when i pushed the 5800H to the max and it was 82W   not 40W or that is measuring different things?

Have you tried using AMD APU Tuning utility yet? You can lock the TDP at 35w which is what I usually do. No noticeable performance difference to me.

Does locking the TDP mean the CPU is using 35W all the time, or will it never exceed the target, operating at lower levels when that amount of power is not needed?

Sorry, I misspoke. Within APU Utility I cap the PL0, PL1, PL2 TDP at 35w, rather than lock TDP. Correct, with these settings the CPU never exceeds 35w, it operates lower as normal when power isn't needed.

Thanks, but do you do 3D rendering, graphics work? i am a bit confounedd that 35w will same performance as 82w.  The 82w i got was in Unreal Engine. It think it was compiling shaders too.

 

Gotcha. No I do not do rendering. I think a good starting point then may be 45w - 55w and see what happens regarding temps and performance? If you haven't already, try Legion Toolkit and Legion Fan Control. Those combined with APU Tuning Utility may help your temperatures.
