It should work just make sure they are not set for dual channel see manual :"Due to CPU limitations, read the following guidelines before installing the memory in Dual Channel mode.
Dual Channel mode cannot be enabled if only one DDR3 memory module is installed.1.
When enabling Dual Channel mode with two or four memory modules, it is recommended that memory 2. of the same capacity, brand, speed, and chips be used and installed in the same colored DDR3 sockets. For optimum performance, when enabling Dual Channel mode with two memory modules, we recommend that you install them in the DDR3_1 and DDR3_2 sockets.
Read the following guidelines before you begin to install the memory:
Make sure that the motherboard supports the memory. It is recommended that memory of the same ••capacity, brand, speed, and chips be used.
(Go to GIGABYTE's website for the latest supported memory speeds and memory modules.)
Always turn off the computer and unplug the power cord from the power outlet before installing the ••memory to prevent hardware damage.
Memory modules have a foolproof design. A memory module can be installed in only one direction. ••If you are unable to insert the memory, switch the direction."
That could cause problem you have to test but for single channel they should work.
