I see the same conditions as in just every AM5 DSDT that was posted here, and every set of patches provided by CorpNews.

Here is a generic version of these three patches which should do for your motherboard… and many others, I hope.

This also works with me too! Ive been scratching my head with sequoia for a while now, and finally with these patches I can boot! Thank you!

Hi @etorix Have a x670 Hero too. 
Could you please create a patch ? Sorry for bothering you. I swear this'll be the last time

You're not bothering. A short analysis of your DSDT suggests that my set of generalised AM5 patches would work with this motherboard as well, so you're welcome to try and report if we can add your X670 Hero to the above ROG Strix B650E-F.

 

To explain a bit: There are some padding bytes between If() (opcode: A0) and the conditions (opcodes: 90 and 9232 for && and !=). The content of these bytes can vary from board to board, but as long as the DSDT is not massively rewritten so as to change the number of padding bytes (here two), it's possible to set a mask and have "universal" patches.

With a hex editor one can look for the core parts of the patches (excluding the A00000 part at the beginning):

#1: 90 92934730 30320A03 93473030 3001

#2: 90 92934730 30320A03 90934730 30300192 93473030 340C2210 FA43

#3: 90 92934730 30320A03 93473030 300A02

There should be a single occurence of each of #2 and #3 in the whole DSDT.aml and a single occurence of #1 that is preceded by A0xxxx (A0 and TWO bytes), plus a few occurences of #1 preceded by A0xxxxxx (THREE bytes, thus not patched.)
