THX in advance!

What are you looking for that you don't see? Gigabyte normally only hides very little, if anything.

What are you looking for that you don't see?  Gigabyte normally only hides very little, if anything.

As of B450AORM.F40 update, AMD CBS options are still partially locked, it shows you custom pstates and soc oc but nothing about Precision Boost Overdrive or XFR enhancements.

I've tried almost everything in order to get them up, such as PE32 CBSsetupDXE module editing using HxD, I've tried other modules aswell such as SETUP, but still no luck.

I even tried to reverse engineer the aorus b350 already modded bioses by crosschecking them with their oem counterparts to seek for changes but I don't know exactly to look for since there are a ton of options and entries.

Any hints on what to look for? I have a ryzen 5 2600 which is PBO and XFR compatible, also I could find those entries in the CBSSetupDxeRV and ZP modules (suppressed if) but even after flashing it no changes were made.

How are you editing CBSsetupDXE? This would be correct thing to edit, show me one setting example stock IFR output, and then how you edit it via IFR example (either post edit, or just you edit the IFR text/show me etc). Normally all you have to do for a missing setting in an already visible menu is unsuppress it, which can be done several ways.

So if this is what you'd done, shown me in IFR example (not hex), so I can see your intended edit in IFR format. Then if it's a correct edit I'll let you know it's OK, and that just means that way doesn't work, then I'll give you the other ways to do same thing so you can try those instead.

* Edit - Here, to save us some time, this is one example using a setting you mentioned, all of these methods may work, or two may fail and only one works, try them all until you find the working method. Always output your edited module IFR too, so you are sure you didn't break the module.

Precision Boost Overdrive - Please note, this is in two modules CBSsetupDXERV and CBSsetupDXEZP - additionally CBSsetupDXESSP contains more settings, one similar to this but called "Precision Boost Overdrive Scalar" - sorry I don't know AMD, so you'll have to check it all out, just giving how to edit examples here so you can find the one that works.

For your main Precision Boost Overdrive I would edit both CBSsetupDXERV and CBSsetupDXEZP

One of those methods should work, if done correctly and to both modules.

Im not modding expert (more or less), nevertheless, if i remember, CBS is meant to be used with only 1st generation of Ryzen CPUs, i cant list architectures, but it were only Zen 1 and 1+ latest i think. Not sure about Zen 2, but it wasnt targeted by CBS anymore i think. All newer cpus.. like Zen 2 and Zen 3 architectures are meant and prefer only using AMD Overclocking feature when doing fine setup and tune up, so AMD Overclocking includes everything you need (in some cases CBS does not appear anymore, which makes sense). (there is no sense in using CBS + AMD Overclocking at same time, simultaneously.. because only one is applied and most of features have duplicity).

Also what i have seen so far, CBS has never had option to use PBO+CO, cause these features were NOT present in first generation Zen cpus. It should be listed only in AMD Overclocking or one or two lines below on the same screen.

Feel free to add more (exact) info, if you have.
