Well, I looked at all of your photos, and (as you said) there is nothing I can see that identifies that board, except that it supports the 1155 socket.
Your cpu-z photo shows that it has a Sandy Bridge chipset.
the processor you asked about (https://ark.intel.com/content/www/us/en/ark/products/65727/intel-xeon-processor-e31270-v2-8m-cache-3-50-ghz.html ) also supports the 1155 socket. BUT... This does not mean that the motherboard bios actually supports that processor.
Now, the processor is an ivy bridge xeon processor. If the board does support it, it would have to have a bios upgrade in order to do so.
Without proper bios support, the processor may work, may partially work, or may not work at all. And, you risk damage to the processor and/or motherboard. And, there is the question of power required for the processor as well as cooling for the processor.
So, without knowing whose board this is, and what their specifications and cpu support requirements are, there is nothing that can be done here.
