2 x U-DIMM, Max. 16GB, DDR3 1866/1600/1333 MHz Non-ECC, Un-buffered Memory
Dual Channel Memory Architecture
* Refer to www.asus.com
for the Memory QVL (Qualified Vendors Lists).
* The default memory operation frequency is dependent on its Serial Presence Detect (SPD), which is the standard way of accessing information from a memory module. Under the default state, some memory modules for overclocking may operate at a lower frequency than the vendor-marked value.
* Due to the chipset limitation, we recommend that you use single-sided 4GB or 8GB, or double-sided 8GB DDR3 per DIMM slot. The maximum memory for the two DIMM slots is 16GB.
