Memory 

* The Max. 32GB memory capacity can be supported with DIMMs of 8GB (or above). ASUS will update QVL once the DIMMs are available on the market. 
* Hyper DIMM support is subject to the physical characteristics of individual CPUs. Some hyper DIMMs only support one DIMM per channel. Please refer to Memory QVL for details. 
* Due to CPU behavior, DDR3 2200/2000/1800 MHz memory module will run at DDR3 2133/1866/1600 MHz frequency as default.
4 x DIMM, Max. 32 GB, DDR3 1866(O.C.)/2133(O.C.)/2200(O.C.)*/1600/1333/1066 Non-ECC,Un-buffered Memory
Dual Channel memory architecture
Please refer to www.asus.com or user manual for Memory QVL.
