I have a Xeon e31225v5 and have been looking into using it on my z170a MSI titanium mpower board I’m very new to bios modding and am struggling to work it all out
I realise being new to this is a bit of a pain for you but we all have to start somewhere thanks for any reply

@Jonno - I've helped a few users with proper BIOS for MSI Z170 and Xeon here, search around and you will find the thread, info, etc and what needs done is discussed there, maybe even BIOS already made for your board.
If you still need help on that, and can't find the thread to bump/add info/request too let me know and I will try to find for you.

yeh I was interested as I have got a free xeon and motherboard I have got an intel mobo aswell that it runs on at the moment the only thing that is a pain on the intel board is the fans run flat out all the time plus I wanted to mess witht the baseclock I like tinkering lol
I got my i5 6500 to 4.2ghz from 3.2 on air and its great lol ive pushed it further but its not very stable as everything else obviously speeds up with the baseclock
the xeon has a higher stock frequency and I have access to many of them for free lol

@Jonno - Sounds like ME FW issue there, corrupted or disabled, not ideal or needed for this "I think" but I could be remembering wrong.
I will see if I can find the thread later tonight, I think it's just certain older ME FW you have to use, and then possibly certain microcode too not sure, but we have it working on several MSI models I'm fairly certain.

thank you very much your awesome
ill look through the threads bud

Ahh, it was Asrock AND MSI, here's the two threads. Right now I don't have time to skim through, but I will later, for now, if you will look through each, especially the MSI one (but do look through both) and see what I did for success then let me know it will help me do it quicker later.
Trying to boot a Xeon E3 1270v5 on Asrock z170a-x1/3.1 (Help) (2)
Xeon E3-1240 v5 working with MSI Z170-A PC MATE but with bios reset on boot
^^ This thread, for this exact board and V5, all 4 BIOS I posted in post #22 run w/ Xeon, but unsure his model/your model right now, may need to re-edit those with microcode for your model (not looking at any of that right now, no time)
* Edit @Jonno - Yes, I just checked those BIOS, all x4 compatible with your CPU E3-1225 v5 (506E3), and already confirmed working on that thread

And I see, ME Does need disabled, but via HAP Bit set only (not sure if that still causes 100% fan)

* Edit - Do you have flash programmer? What is your current ME FW version, check with HWINFO64 as mentioned below, and send me fd.bin as outlined below, then I can tell you if we can downgrade your ME FW/how to flash in those BIOS etc
