Looking for starting point - Ryzen 3600 overclocking in 2020

Hi.
So I followed ryzen 3000 launch coverage and there seemed to be a lot of drama regarding high Temps and pbo + auto OC not working and what not.

Now that BIOSes have matured I've finally gotten my hands on a 3600. So where do I start?
I'm coming from a 2600x where I found best gaming results with a fixed undervolt @1.3125 and PBO maxxed out on bios.
However from what I understand fixed undervolt actually reduces performance in 3000 series. So can someone share a link or a thread which will be a good starting point for me? I want to understand :

1) fixed all core oc vs PBO vs auto OC maxxed vs per ccx OC?
2) ryzen master for OC vs OC in bios?
3) what impact does 'Cool & Quiet' and 'Spread Spectrum' have?

There must be a hundred guides about that, as this fly is quite mainstream.
I would suggest that the fixed oc is the way, as it seems to give better results.
Just set in bios your favourite voltage and ran timings and test with Ryzen master which CPU frequency works better for you.
Offset voltage will you a safe range of flexible voltage according to the needs of the cpu.

Just moved from 1055t to 3600. People keep saying these guides exist but really they don't they best ive found are a couple of 'tech media' saying what options exist. Some are useful and good baselines but there really doesnt seem to be a cureall for the settings needed. Cheers and hope everyone is grand!

I turned of that boost stuff, that seems to help. Set vcore @ 1.41 and see how high it will run something like Cinebench.

Mine didn't make it to the advertised 4.4, but 4.375 is close enough. Lowered down to 4.275 for daily with around 1.3V

Apparently I have crap RAM. I uhh..decided on 2400 Mhz and this: Oh no! Wrong profile..brb.

Yeah thing is most of those are from 6 months ago. For example one person on here mentioned this 'trick' of setting edc to 1 for best PBO results.

In this case are you talking about stress testing with ryzen master? Or overclocking with rzyen master?

I don't think much has changed in regard of OC'ing since launch/few months after launch.

Best to OC the RAM, keep to 1:1:1 for FCLK:UCLK:MEMCLK. Do bare in mind that you may not see the gains in gaming from this unless have a decent GPU, link.

If your after least hassle for core OC, I'd set Precision Boost Overdrive to manual, set the PPT: 142 TDC: 90 EDC: 140. This will give the limits of a 105W CPU (ie R5 3600X). Bump Max CPU Boost Clock Override to say 200MHz, see if the CPU exhibits clock gain, then run some benches, compare it to a lower override. Which ever MHz gain gives performance gains with clock increases is the one to use, others maybe exhibiting "clock stretching".

I have not done manual core OC, if you decide to, using this method posted by The Stilt you can see what the CPU SMU determines as "safe voltage" for 24/7 use under high load. This value could be what you wanna be around for your manual OC. Per CCX OC again I have not done.

I have had several Zen2 CPUs, R5 3600, R7 3700X & R9 3900X. I always setup profiles via UEFI (BIOS).

If you go PBO OC you wanna keep things like 'Cool & Quiet' & 'Global C-States Control' set to 'Enabled'. The cores not in use will enter lower power states/sleep, so the ones in use will boost better.

Spread Spectrum is a feature used to alternate frequency to reduce EMI. When OC'ing you wanna have this off.

Use RM for ocing inside windows. It's the fastest way to try different CPU freq on the fly.

The only oc'ing i've tried on my 3600 is manual oc. Only played with 3 settings. Core ratio, CPU vcore by + offset, and llc. I've achieved a 4.2 oc with vcore of 1.33v at load.

IMO, if you cannot oc at least 4.2GHz and your use case requires mostly single threaded tasks, you'd be better off at stock.

Edit: Clocks stuck at 4.2 but vcore and wattage both lower down using Windows Balance min processor state 5%.

Thank you so much. THIS reply was exactly what I was going for.

Couple of things though,
1) I'm assuming pbo is unchanged from the 2000 series. Worked great for the 2600x, not so much for the 2600. Does the same apply for 3600 & 3600x?

2) This auto overclocking is new but even set to +200mhz, I never see the clock speed in my 3600 going beyond 4200.
If that's the case isn't an all core of 4200 @1.33 better than pbo + auto OC +offset voltage?

Many people claim that PBO doesn't offer any advantage over the manual all core overclocking.
My tests show the same that better results are coming with manual oc.

How else I could get 4.4ghz all core for all apps?
