Finding Microcode For ES CPU

I have an ES CPU and I think my motherboard possibly doesn’t have microcode for this CPU hence not running and giving a CPU error.

I have managed to get the mmtool 5v (patched) to work open the bios and extract and add new microcode that i have extracted from other motherboards that people have confirmed worked with this CPU.

Any help is greatly appreciated

What is the CPU S-Spec? It should be printed on the IHS (metal cover of CPU)

Unsure what you are asking here? Do you need the microcode, or you already found it? What is the motherboard model?
