Do all LGA 1155 Motherboards work with all LGA 1155 CPUs?

Zell Faze asked:

Hardware is an area that I have very little competence in. I’ve recently been tasked with the creation of a new server for the company I work for.

I’ve priced out a motherboard and CPU for the server, but am not 100% sure if they will work together. Before making the purchase, I felt it would be best to ask here first and make sure. To keep the question useful, I’ve expanded it’s scope a bit.

Specifically I’m trying to Intel Xeon E3-1230 into a ASRock Z68 Extreme3 Gen3 LGA 1155. The CPU uses socket 1155 and the Motherboard has socket 1155. The confusion arises in that the motherboard’s description page lists the i3, i5, and i7 as supported CPUs and not the Xeon.

So, will all motherboards with LGA 1155 sockets work with all CPUs that use 1155 sockets?

My answer:

Whether you can successfully use a Xeon processor in a desktop motherboard depends on BIOS support for it.

The CPU support list for this board lists the Xeon E3-1230 as compatible, with BIOS version P2.10 or later.

You may need to use a different processor to update the BIOS before installing the Xeon.
