HP Z420 motherboard upgrade from V1 to V2

A small upgrade to HP Z420 motherboard to support newer Ivy Bridge processor family. Yes it's old but it's still an ok processor and costs next to nothing.
V1 motherboards are exactly the same as V2 but the boot block prevents using the newer Ivy Bridge processors.
This video addresses that issue.
Boot block is write protected when the computer is on so you need something else to program that portion of the bios, there are good tutorials online for the problem and this is just my take on the problem.
I used soldering as I have the tools for it. But some may use the raspberry Pi method.

Hey I am late to the party but will ask... If I have a bios 03.96 rev.A → I should be able to run v2 xeons. Right? I sadly don't have bios programmer, skills and tools to make such a mod so wanted to ask. Is there a way to check without that, which version of motherboard i got?

Awesome!

I am trying to figure out if I have v1 or v2 mono. I have bios J61 v3.92 and a 12/28/2011. Can anyone help me to understand?

[@blooga3941]

That will be V1 I imagine. I think V2s had a date of 2013. (Could be wrong)

So we'll be any manual how to change hexes i mean which hexes to change

[@RandomBSOD]

Is odd you had to go through this whole process for a simple v2 CPU upgrade. I had this same system 2 years ago, and simply updated BIOS to 03.96 Rev.A and after flashing, it took the V2 CPU without any issues.

You had the luck of having a V2 compatible motherboard. There are 2 versions of it.
