Hello. I urgently need to update microcode 00600F20 to the latest version
Link to latest microcode CPUMicrocodes/cpu00600F20_ver06000852_2018-02-06_893C1544.bin at master · platomav/CPUMicrocodes · GitHub

I need to update this particular microcode very urgently
I looked at the manuals, and did not find the update instructions for AMD processors (and I don’t have time to delve into the manual)

Also, if you wish, I will be very grateful if you update other microcodes

Follow this link: ASUS M5A78L-M LX3 MC Update (bios-mods.com)

Do as instructed and be prepared for any system fail, this is AMD board with AGESA…always unpredictable results.
Good luck.

EDIT: You maybe out of luck waiting for it…this is an old board model and we cant expect that a user will lost his time with this, do as you please.

Thanks for the link.

I need a long time to study this manual, so I will still wait for modders who will

According to the instructions, I extracted E2, and then I need to open it in the HxD editor? Find my offest microcode and replace?
If so, how do I find the start and end of my particular microcode?

As I understand it, in order to manually update the microcodes through the HxD editor, I need to know the address of each microcode so that I can manually replace it
For example, the link that MeatWar gave above to Bios-Mods,
cpu00600F20
address : 225a0h - 22fbfh
But in the HxD editor, he did not find the value 225a0h. In that case, how can I find it so that I can replace the microcode?

No, thats on that model motherboard and example, linked, yours is different address on that module.
The tool MCExtractor/MMtool 3.x can be used.
Keep in mind ALL info on that linked thread, all of it till the end, it needs adjustments, there was no report of any user later on.

Yes, but MCextrator does not show the exact address 00600F20
I don’t know how to find out the exact address to replace

EDIT: Sorry… if you do a question like that, then this is not really for you, why? Because the answer to your question is already at your front and still you cant see it.

The main question is how to find the end of the address Offset 0x25A0?
I couldn’t find such information on google (not even ChatGPT helped with this), so this forum or you is my last hope
