I have just built a rig with Ryzen 5 3600 with B450 Strix-F. On latest bios 2605 (Aegesa 1003 ab). All core boost clock (PBO + auto overclocking) is only 3950Mhz during CPU-Z stress test and Aida64 stability test. single core boost also never goes beyond 4100Mhz. However i can manual overclock to all core boost clock of 4200MHz with voltage of 1.4V, Aida64 stable for 30min.

I am using 360mm AIO and my CPU temp is good. Max load while on PBO + auto overclocking was only 72C. Hence the PBO is definitely not limited by the temp.

Any sifu here can confirm whether PBO is broken for B450 chipset with latest microcode?

not sure on b450 bro but your scenario pretty much d same on my x470 carbon. single core boost might be tied to the trifectors, namely PPT, TDC & EDC. i admire ya setup bro, i have same cooling as yours & a 3600, d chip cant manual oc for its life. even @ 3.9GHz i need a whopping 1.45v & that's not AVX stable. temp can even reach till boiling point as well @ 3.9GHz. if i were u, i'd stick to your current setting @ 4.2Ghz, with some tweak on CNQ and/or adaptive voltage. 4.2Ghz w/ 1.4v with that kinda temp is pretty good to my book already. notworthy.gif

pbo is pretty much broken across platforms, that's not limited to b450

if you're fancy to OC at this moment, do auto oc only.

actually if I were you, at this moment I would simply adjust PPT, TDC's, and EDC's.

From reddit it seems PBO is still broken on ASUS B450.
Not sure if other vendors managed to fix it or not though.

Btw, curious how come some users managed to get PBO worked?!

The PBO + Auto OC definitely works well with my 3600. I'm now hitting an all core boost between 4.25GHz and 4.3GHz during gaming and a single core boost of 4.4GHz. Before enabling PBO + Auto OC i was capped at 4.1GHz.

Auto OC yielded same result for me. So gonna stick to manual overclock at this stage

Gonna try to downgrade to previous bios with aegesa 1002. I heard PBO is better on that version

pretty much max freq can be squeezed out from d x470 + CJR... smile.gif

Even though I hate mem (benchs) on settings that are far from being stable for long term that's a pretty good 2666 rated kit you got there despite your timings are suffering big time to achieve the frequency.
That cpu however o.O 4.125GHz with 1.456V … damn. Mines doing 4.225 more with 1.415 (AVX ST) (which translates to 1674 mc cb in r15)

agreed, 32m would be d very basic memory stability test. Whack d setup with even tm5 i see errors with a min. I would say ram mileage on ryzen 3K is very2 forgiving, especially on itx boards (if bios/agesa done rite). Thing is anything above 1:1 (3733) is pretty much pointless, running ram above d mentioned frequency is really for d sake of fun/exploring d mileage only. smile.gif

CPU OC is pretty much stock or nothing. I gave up wholeheartedly. As long as it runs am grateful enuf already... Such a big big lemon i must say... biggrin.gif
