Thx i try the beta for my msi b350m gaming pro(very poor motherboard) and i can easily be stable at 3600 with H5AN8G8NCJR-TFC Patriot Memory 3733 C17 Series .

Seems that agesa is very compliant with high end memory .

Sorry for staying quiet for some long time~
I had a long time to play around with HynixMFR's (got it up to 3400mhz), temp-bricked my X370 Taichi by picking wrong AMD GOP xD and played around with mid 2019 microcode updates spread across C7H & Gigabyte Bios's

Юрий, is 1.0.0.1 an update from 1.0.0.0a or 1.0.0.4c?
(These comboPi names are confusing when lower number is newer most of the time) ^^'

I inspected the latest Gigabyte Bioses how they implement Zen 2 Features and IO Die PCIe 4.0 support
Still struggling to find out why Asus on C7H needed to increase container amount to 32mb instead fitting it like Gigabyte can on 16mb Rom
Btw, your PMU guide works perfectly
For both of my boards with AGESA >0.0.7.2 , it's 3FCE to code 2 & 45CC to code 3

Gigabyte F40 "updated to new AGESA" still is 1:1 the same AGESA 1.0.0.4c / 0.0.7.2 PMU
Makes me question, what is now actually the latest AGESA as the current C7H 2304 is on an 0.0.7.2A but with old microcodes

Also code 1 seems to be identical on the new bioses (Gigabyte, Asrock and Asus's X470 lineup)

I forgot to ask, do you know by any chance the Hex location for changing the shown AGESA version/name ?
It bothers me that it says 1.0.0.6 while i'm on 1.0.0.4C

You can pick 4207 by 1usmus and check Page 121 & 122 for how to update microcode & AGESA/PMU to 1.0.0.4C
(be sure to update UBU to v1.74.0.1 for latest microcodes)

Or grab the latest 4801 from the support page with AGESA 0.0.7.2A and inject latest microcodes if you optionally want
Technically i could do the patching for you too - but it's better when you learn something

There is a file that is responsible for the signature, but it is also a hex , GUID AB56DC60

AGESA and PMU firmware are different things, try not to confuse

I think this is not all, there are more pieces of code that are responsible for training settings

Now i understand you fully, took me some time with the GUID part - should've read your soft-modding guide better sorry
But i hang sadly a bit at ".sct module can't be extracted, protocol Unknown"
Tried the same also with latest "IFRExtractor LS" - both times can't extract the package
Note:
My .rom file was already the smaller size not "2KB smaller then your .cap file"

I use your Pre-Modded "old" Bios with Spread Spectrum changes as Source

Are both PMU and AGESA together in one code patch (2,3) or separated ?
Would like to grab the 0.0.7.2A from the C7H over or overall try to source down best of both worlds~
You said 1.0.0.1, is this AGESA or PMU - what does AMD mean with "ComboPi"
Edit:
If i extract the whole section "as body .bin" it allows me to hex-edit it but there are no signs of numbers

I just want gaming performance should I do it? thanks
Same here sadly :/
Very unlucky with silicon Lottery (even tho it was a gift)
It let's me boot even 4.3 to windows but there is no way how i can get it even remotely stable under 1.56v :x
Needs 1.35v for 3.8 with 3400mhz rams under 1.0625v SOC, and 1.42v for 3.9 to stabilize
(still struggling with cooling, even tho it's lapped - soldering pressure holes where huge)

I noticed the 4801 is out with "Agesa" PMU 0.0.7.2A for the mPRIME
Try to keep tDIE under 75c optimum hovering at 68c, and memory latency under 72ns (personal finding)
Over 72ns you start to bottleneck Zen 1's IF
(AIDA64 to check MemLatency)

Overall unless you have memory OC problems - you can use the newest zen 2 ready bios and the same recommendation
Update Microcode with UBU and maybe grab 1usmus's modded bios as template for manually modding
- if you wanna go fancy and stay on the cutting edge
