Question Ram compatibility

Supports the latest Intel processors delivering native support for DDR3 memory up to 2200+MHz by the enhanced design of GIGABYTE.
* Please refer "Memory Support List" for memory support information
Well its always better to buy tested ram from the motherboard list. Your motherboard supports up to 2200MHz ram so 1600 is not a problem. For ram kit out of the list is just not guaranteed that will run at advertised speeds but most of the times it just works fine. I bought many times kits out of support list and worked fine especially for gigabyte motherboard their list is short and they dont test many kits.
