Bios confusion regarding board MFG and AMD "Overclocking" settings

So I've noticed that on both my Aorus x570 Ultra and MSI x570s Carbon Max WiFi that there are 2 areas for overclocking, one is at the surface level in the bios under an area simply labeled overclocking and the other is the AMD Overclocking buried under a warning that has to be accepted. While these 2 areas have much the same settings, changing one does not seem affect the other, such as PBO and vcore offset to cpu voltage and + setting for core boost, etc.

My questions would simply be 1. why do board makers feel the need to have both as it seems redundant and confusing to the end user, and 2. which is the better to use when tuning.

While I'm sure this has been covered, I'm just looking for a recent perspective on the topic.

the one that requires the warning has more control, like individual core adjustments/curve optimizer. i dont bother with it and just turn on pbo.

AM5 boards still have it like this. Really dumb and confusing. They should definitely consolidate into one section.
When it comes to overlapping features, there is no difference. PBO turned on in one spot, results in the same performance as if it were turned on in the other.

yeah, that's what I've done, but more recently decided to try using a negative value to improve boost performance and this is where I noticed the difference to overclocking areas in the UEFI, and again the fact that they do not show the same data is odd.

it is, not sure why. re voltage; i just use a normal - offset on the cpu/ram config page.
 
Asus is notorious for this. My old B550 Strix board has two near identical PBO sections. One in the AI Tweaker/Overclocking section and another buried in the AMD Overclocking menu in the Advanced tab. Only the latter actually does anything.
 
as a quick follow up, what I've found is that if you use the "normal" OC section of the bios it affects the AMD OC section, but doesn't seem that settings in the AMD OC section affect the "normal" section, so it would seem it's just an overall poor implementation of features, no need for them to be in one place.
 
Yeah, I think the AMD OC settings adjust settings which reside on the processor itself, directly, whereas the stuff outside of there adjust those settings and save to cmos as well.

They could have hidden them, but since they're available on most/all processors and overclockers would probably complain if they were hidden, it makes sense to keep them (even if they're mostly hidden in the advanced section, behind a disclaimer). Otoh some are useful for basic overclocking/tuning, and those are exposed in a limited way under the Easy OC screen, and sometimes on the summary screen.
 
I think they're basically derived from the main AGESA provided by AMD which then the board vendors make their BIOS from it. I saw it on AM4 on every brand and it's on my AM5 Asrock now. Yes, some settings are duplicated from main BIOS settings pages, but there is also some stuff in there that you won't find in the normal menus.
