hey look, im trying to oc via Dynamic Vcore now, i just added 0.060 V to the base voltage, but im having different readings from every software, anyone know the reason? i think im just going to stick with manual overclock, it is way easier haha

(cpu-z is fluctuating between 1.128 V and 1.140 V)

Oh is this for real?
4.1GHz with 1.08~1.1V. Where did you buy this CPU? I want one...
Believe the "CPU core voltage (SVI2 TFN)" and the "CPU core VID (effective)". RyzenMaster shows the same and CPU-Z is not qualified to report a valid value for Ryzen 3000.

No, do not alter LLC, ever, unless you have a good reason to do so. Like to compensate from excessive voltage droop. Using it to improve voltage on VRMs that are possibly struggling is an absolutely terrible idea. Overclocking with the vcore offset is going to scale the voltage at all vid levels. Setting a voltage through manual overclocking locks you to a single VID level regardless of CPU state. I personally think that this is not a good option for any 24/7 overclock and only for when you're chasing numbers, otherwise your machine is not going to run cool and it will probably run worse if it causes you to become thermally limited.

That's because the offset you provided changes the voltage at all VID levels, so when the CPU clocks up (and in turn, asks for more voltage,) your offset will be applied to what the CPU is asking for. The fluctuation you're seeing is the CPU changing clock speeds and in turn, voltage.

He runs the CPU 100% load with under 60C there is no thermal issue. And he actually lower the voltage with that offset. As I said you have to look to SVI2 TFN.

Ryzen ClockTuner provided a good enough reason for me to enable LLC for the power efficient all cores OCed option. Slight Vdroop during testing. The offset option doesn't seem to work for two different CCX 0/1 clock speeds set (Black screen, and cycling input source.)

do you think that should i leave it that way then? with +0.050 V OCCT showed me some errors, but with those +0.060 V seems to be stable after a complete 1 hour test

Leave it where its stable. Your CPU runs really unstressed in terms of voltage (under 1.2V) at 4.1GHz. Everything is under limits, runs super cool...
Its ok!

I ran occt again just to be sure and i got some errors this time, should i not be using the pc at all while occt is running? Because those errors popped up a few seconds after i opened chrome

I'm not familiar with OCCT stress test.
I suggest to back off a little with benchmarks and stress tests and use your system and enjoy it on your daily tasks/entertainment/gaming for a few days and see how it goes.
