2-14 Chapter 2: Hardware information
2.4 System memory
2.4.1 Overview
The motherboard comes with sixteen (16) 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 figure illustrates the location of the DDR3 DIMM sockets:
2.4.2 Memory Configurations
You may install 2GB, 4GB, 8GB, 16GB, and 32GB RDIMMs or 2GB, 4GB and
8GB* with ECC/Non-ECC UDIMMs or 8GB, 16GB and 32GB* LR-DIMMs into the
DIMM sockets using the memory configurations in this section.
• *Refer to ASUS Server AVL for the latest update.
• Start installing the DIMMs from slot A1 and E1 (light blue).
• Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules from the
same vendor.
