Ya, it's pretty telling

Their CSR thinks:

AGESA updates have suddenly included 'hiding' CPPC and CPPCR from the BIOS that it is not a menu option any longer

Yet meanwhile the voltage offset is still in the BIOS as a menu option, yet you cannot modify into a positive numerical


Would be nice that any other users here comment on whether they have CPPC any longer(or ever had it on their model)

As well as can they set positive offset?

"Hello,



CPPC Preferred Cores is usually an option in AMD CBS\SMU Common Options.

The AMD CBS menu completely depends on the AGESA.

CPPC is not supported by the current AGESA version. Because of that, those options do not appear in BIOS.



Perhaps you have heard about 7000-series CPUs being at risk over overheating/burning. Newer BIOS versions come with mandatory restrictions to prevent this from happening. One of them is blocking a positive offset for VDDCR_CPU Voltage."


-AGESA and CPPC have what to do together in this instance
-Surely should this have worked previously (which it did) that a follow up comment would be given around whether this is indefinite or there's plans to change in future



On voltages in summary:
It's fine to continue to have complete control over all manner of things that are equally if not more dangerous to be changing (the BIOS options for AM5 is way too open, there's many things in there not even your average computer expert would ever have need to modify)
You can up your Vcore to risky levels, as well as positive Curve Optimizer and overvolting levels

You do this all the while under the watchful eye and reminder in BIOS that overclocking is risky and to ACCEPT the warning(s).

Yet you're not allowed to use a granular fine tune method of amending voltage using a positive offset (even though the offset menu exists and you can do negative offsets..)

Hello I have the B650M-HDVM.2 motherboard and am trying to find in the BIOS where the CPPC and CPPC Preferred Cores settings are

Also, in terms of Bcore/cpu voltage offset, I found only one location for it and that was under AI Tweaker (not Advanced as I was expecting).
And the offset does not allow + voltage only negative - is this intended?

I really want to set a positive offset to help improve/stop the notorious crashing when using Curve Optimizer under low load


Thank you
