Sorry, I take that back. The socket is the same but the BIOS doesn't seem to support it: http://www.asus.com/Motherboards/P8H61M_LX3_PLUS/HelpDesk_CPU/
that is a sandy bridge board. A bios update should allow your Ivy Bridge CPU to work in MOST cases. Go to manufacturer website and download/install latest bios.
However there are several Ivy bridge CPU's on the list and therefore should be compatible as it should be pin compatible with all the Ivy Bridge cpus in that case.

It will fit the socket, that's not the problem here. The problem is the potentially non-existent BIOS support for the CPU.
even if the bios does not recognise the model the Clock and multiplier settings are automatically set by pins on the CPU. The only thing missing would be the name of the model on the post.
