Ryzen 5000 series all core manual OC

[Guest2]

Up until a few days ago I was using PBO and experimenting with the curve optimizer on my 5800X.

It may just be my specific motherboard (MSI MEG Unfiy x570) or beta BIOS but PBO if left at auto was resulting in quite high voltage on all core clocks. I would see all cores boost to 4.7Ghz then quickly step down to 4.55Ghz with 1.365V being applied to all 8 cores. AIDA64 stability test would show hardware errors about 30 minutes in

I now have 4.75Ghz set with 1.275V and see much lower temperatures (gaming max 60c, benchmark 78c) and no issues with AIDA64 though only stress tested for a couple of hours

4.8Ghz I tried 1.2870V but this crashed Cinebench R20. Closer to 1.3 V may be needed for 4.8Ghz+ which I expect will result in a lot high temperatures too

I'll test PBO2 when the new BIOS' are released but manual OC seems a lot more stable than default auto PBO

Same here, I found PBO throws far too much voltage on auto for me.
By default it sets 1.48v which gives me 4.3ghz all core & between 4.9 & 5.05ghz on single core but temps when running Cinebench are well over 80c.

Setting an all core overclock of 4.5ghz with 1.25v temps for Cinebench are 65c & gaming between 55-60c

I've tried 4.6ghz but even with 1.3v its not Cinebench stable although it will run stress test with Cpuz no problems.

I'm guessing bios updates will sort a lot of the little niggles out, but for now 4.5ghz will do

Give me your CPU, I will play around with it and find a setting for ya
