You might brick your board.
Apart my settings from the official 0805 bios, I only changed CLDO_VDDP Voltage = Manual > 955
The message "Applicable only if PcdOcDisable=FALSE" is at the bottom of your 9th pictures, below the title 'Pictures".
I tried to set three P-States, the sames I had trough ZenStates, but in Windows, the CPU was stuck on P1 (2.8 Ghz at 1.05V), as if the P0 and P2 were never activated.
That's why I think "PcdOcDisable" really must be disabled, but I have no clue where to find it.
Even more bothering, after this attemp, I set all the P-States on Auto then I switched back to ZenStates but even it don't work any longer. Fortunately, the fixed P-States trough ZenStates is P0.
I tried to load the Default settings in the BIOS,then I set them all manually, but ZenStates is still stuck on P0.
I still can try to get rid manually of ZenStates then to reinstall it but as the issue started when I tried to set the P-States trough the bios, it would probably don't solve that issue.
If neither the P-States from the BIOS or the one from ZenStates work any more, l'll switch back to a OC with a fixed frequency. The difference on the input power is tiny anyway, but I hope I'll get back the P-States somehow, because I don't really care if they are managed by the bios or by ZenStates.
Damn, you're right! My power plan "AMD Ryzen Balanced just had its "Minimal processor state" set at 100%, despite I had set it at 50%.
That explains perfectly why ZenStates didn't work any more. I stil have to try the P-State trough the bios but now, I know what to check if the frequency become fixed again.
Ok, thank you very much again Reo
I think i'll give it a try, as soon as i'll be able to get the values for a stable low temp oc on this config, cause i'm planning to set up asap a dual boot Win/Linux, so the unlocked options would really be a good thing
Sorry for my english, i'm a bit rusty
Have a good Sunday!

Hey, I would love to know if the tools you use for BIOS modding on the X370 Prime Pro would work for other AM4 models, albeit with the same AMI BIOS ICs.
I want to enable some features not present currently on my AB350-Gaming, which I highly suspect as per Gigabyte tradition are artificially locked out of this model and are present on higher end models.
Anyways, thanks in advance!
