@KedarWolf - this may help guide you along for some of that, FIT will need corrected too and that's more involved than microcode update (Which is covered a little bit) - [GUIDE] Update CPU Microcode + Fix FIT Using UEFITool / Hex

What you are needing is not a simple modification, and may not be possible, since that is a much older BIOS (1101) than before 9900K was compatible (1704).
ME needs to be a certain version and it may not be possible for end users to put that ME into the old BIOS, what is your current ME on 1101?
BIOS setup module will need edited, as well as several other modules (like they do in the sky/kaby to coffee mods probably), in order to support that CPU on such an old BIOS.

You're current issues/instability may be you need to get used to and stabilize your new CPU vs how the old BIOS acted with your old CPU that you new well.

If you simply want to try a microcode add in and see what I mean I can do that for you. Are you able to recover if 9900K non-bootable, do you have older CPU to drop in when 9900K does not work, that way you can flash back to other BIOS?
Or does your board have two BIOS and a switch to select BIOS? If you do have older CPU, what exact CPU so I can make sure to leave it's microcode in there if I need to remove one to make room for the 9900K microcode.

i have 6950X who is latest?

@KedarWolf - vbios and setup module may not be compatible too, and possibly other modules as well, it's not always simply microcodes. I'll have the 1101 BIOS + 906EC microcode ready if you need it, that may work but I kind of doubt it but I suppose you never know
Which microcode do you not care to loose (or two if space needed) >> 506E1, 506E3, 506E8, 906EA, 906EB, 906E9

*Edit, posted this right when you replied above, please answer my question about loosing microcodes above and I'll make you a BIOS

@panosxidis i7-6950X - 406F1 latest is - 0B00031 - https://github.com/platomav/CPUMicrocodes/tree/master/Intel

@KedarWolf - thanks, but nothing needed to be lost this time around, all original microcodes remain + 906EC
Good luck and hope it works for you, this method of what you are trying I mean, BIOS/mod will be fine as it is! Flash using USB Flashback

https://prnt.sc/log0k9 see i have B000031!!!!nop the 0B00031

Thank you!!

I'm at work right now, but will try soon as I get home.

I'm so grateful, on my 8700k, 1101 with updated microcode etc. was so much more stable than the latest, 1704. :)

@panosxidis - same/same, that is microcode version ID, so you already have latest installed.

@KedarWolf You're welcome! Hopefully it works for you that way - Fingers crossed!

i have one question latest microcode is always stable and more perfomance?or not?thank you very much!

No, not always, it's only considered best for security and up to date with most fixes. Other older may be better for stability/performance, but can be less secure to possible hacks like Meltdown/Spectre recently.

Maybe your edits cause the failure? Did you test without any of that, as I sent it? If not your edits, I assumed it might not work that easily, due to all the things I tried to explain to you.
To confirm what I mentioned is correct, try it with the other older CPU, if it works then it's as I mentioned.

UBU microcode updating? I showed you in image it was updated as requested, but much more than that will be needed for what you want to do.

You're welcome. I think many other modules would need updated for that to work, starting with the ones I mentioned originally but that may not be all required
