For me, the most useful unlocked option is the CLDO_VDDP Voltage, because it's the one I lacked to stabilize my RAM at a higher frequency than 2933 Mhz.

I tried to test the P-States trough this modded bios but its says "Applicable only if PcdOcDisable=FALSE".

Where is this option in the bios?

What settings have you changed? Have you tried to load defaults settings?

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.

I sincerely hope your release of this results in ASUS waking up and giving these options in the next official BIOS

Not too fussed with the extra options, though Pstate is nice to have. Just wish I could get the memory working faster, though granted its not a huge boost in performance.

Ikr. Not even the Strix X370 Gaming has access to the PStates or the full AMD CBS settings.

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!
