ASUS Z9PE-D8 WS 2-13
2.4 System memory
2.4.1 Overview
The motherboard comes with eight (four DIMM per CPU) Double Data Rate 3
(DDR3) Dual Inline Memory Modules (DIMM) sockets.
A DDR3 module has the same physical dimensions as a DDR2 DIMM but is
notched differently to prevent installation on a DDR2 DIMM socket. DDR3 modules
are developed for better performance with less power consumption.
The gure illustrates the location of the DDR3 DIMM sockets:
You may install 1GB, 2GB, 4GB, 8GB, 16GB and 32GB* RDIMMs or
1GB, 2GB,
4GB and 8GB* with ECC/Non-ECC UDIMMs or
8GB, 16GB and 32GB* LR-DIMMs into
the DIMM sockets using the memory congurations in this section.

• Install the DIMMs starting from slot A1 (CPU1) and E1 (CPU2).

compatibility, it is recommended that you obtain memory modules from the
same vendor.
