cpuB06E0_plat01_ver0000000E_2022-09-01_PRD_6C26DFE0.bin

Remember, there is a version for platform 11 but I am unsure wether it is applicable to the specified platform. Maybe someone can clarify this.
cpuB06E0_plat01_ver0000000E_2022-09-01_PRD_6C26DFE0.zip (131.2 KB)

Update 2024-04-01:
The file cpuB06E0_plat11_ver0000017_… is compatible, contains platform 0. Therefore no need to keep this file. Just update to the one published by platomav.

Thank you for the report! It seems the change is at the Loader ID (which denotes compatibility usually) so it can work easily.

Like with some other recent Zen microcodes, AMD has finally added a field to denote the size of the microcode (Data Size). In this case, I can see the header reports 0x3820 and the blob you shared is indeed 0x3820. Just to be sure, do you have the originating container file (e.g. BIOS) to check if it is followed by padding etc?

Oh, my friends, a lot needs to be changed and done for UBU, a different approach for new BIOS. I’m going to upgrade from socket 1150, my favorite, to 1700.
And new AM5.
I tried to help the guy, but I had zero knowledge.
I will come in and peek, but I won’t help anyone else.Hi need to have at least basic knowledge. AND READ ONE LINE FROM ME, NOT A PAGE!!!
