So why keeps displaying "unsupported cpu" on boot? If I press f1 it boots fine, if I don't it shuts down

It isn't microcode issue.

in the manual of hp pro 3300 there are only a few supported cpus, so I think the microcode has been modified to support only cpu listed in the manual

Make BIOS dump by your hardware programmer.

Nice news! It was TDP issue.
I patched only two bytes:
0x3B6029: DE -> 69
0x3B9025: 76 -> EB

It was mod for dom93's mod only. You can make mod yourself. Change two bytes - https://www.bios-mods.com/forum/Thread-H...#pid163137
