Greetings,
Unfortunately, the memory you have chosen is not natively supported by your board (Chipset and CPU).
6 x 1.5V DDR3 DIMM sockets supporting up to
24 GB of system memory(Note 1)
Dual/3 channel memory architecture
Support for DDR3 2200/1333/1066/800 MHz memory modules
Support for non-ECC memory modules
Support for Extreme Memory Profile (XMP) memory modules
(Go to GIGABYTE's website for the latest memory support list.)
i7-920 Supports
Max Memory Size (dependent on memory type)
24 GBMemory Types
DDR3 800/1066
Max # of Memory Channels

You are not going to get an out of box "Plug and Play" experience with this RAM. If you have 32GB of addressable memory be happy.
The board does support memory modules up to 2200Mhz, but the DIMM's might run at reduced speeds if the following is true:
Intel processors come in four different types: Single Channel, Dual Channel, Triple Channel, and Flex Mode. Maximum supported memory speed may be lower when populating multiple DIMMs per channel on products that support multiple memory channels.
What this means. You may be able to manually set memory settings in M.I.T. and receive some degree of success with this RAM, but you'll have to experiment to find out what works and what doesn't.

11-13-13-31-2N
1.50v
You will need to OC the RAM to some degree to get it to run faster than 1600Mhz. This may or may not affect CPU as this is an older board now. There is not an easy solution to this issue I'm afraid.
