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?
Is there something like DRAM boot voltage on C6H for prime-pro?
What settings have you changed? Have you tried to load defaults settings?
Quote: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.
Going from the info here. https://hardforum.com/threads/ryzen-pstate-overclocking-method-calculation-and-calculator.1928648/
I only altered the P0 Pstate setting, set it to 9D, which gave me a 3925mhz clock.
I also changed the power profile in windows to set minimum processor state to 20%. Now clocks up and down pretty well.
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
Yeah would be great but i dont think Asus is gonna do this.
