If it works perfectly fine, then I guess the microcodes are not absolutely necessary. It's not like the machine is running anything mission-critical (I hope); if you later notice some problems, you can re-evaluate.

IIRC from my own tinkering with this (several boards and CPU's).
You can miss out on a few CPU features and power tricks.
Run CPU-z and check if you get SSE 4.1, EIST etc.

When you modded the BIOS, did you remove some other CPU microcodes to make room for the new ?

W10 and Linux will upload latest microcode(that they know of) while booting, no idea about earlier OSes
was a pain when overclocking pentium g3258 and some later microcode disabled it on non K boards

Yeah I tried this with a Dell G45 board and had no luck with integrating microcode. It was extremely slow with the microcode added. The stock BIOS didn't support the Xeon well enough to boot most modern OSs but was fast with XP. I'm sure I tried Win10. Without microcode updates to the BIOS, the CPU will usually be missing features.

I remember running Xeon X5450 on Gigabyte P35 board without modding BIOS... and there was missing SSE4.1 support. However when the application asked directly to use SSE4.1, it was there with performance as expected. https://hwbot.org/submission/3417804_havli_hw … x5450_10.88_fps

It's a bios size thing IIRC.
Tho if you want to be sure you could just download a premodded file.

Even if you dont want to flash a downloaded modded BIOS you can use it as a reference for your own modding =)

And if you do use a modded bios.
Could you take HWInfo system summary screens of before and after ?
I'm just curious !

Got my own modded system on HWBOT (2x #1 for Quadro FX5800 !):

There is a bios modding section in this forum, where some very experienced bios modders hang out: https://www.win-raid.com/forum.php
Definitely worth reading!
Regarding microcodes, you might find what you are looking for here: https://github.com/platomav/CPUMicrocodes

My vote would also be without the bios mod if its stable and not missing any features.
I have an x5460 in a Gigabyte GA-EP45-UD3P dropped in with no bios mod. Don't recall if SSE 4.1 is detected or working though.
