2.4 System memory
2.4.1 Overview
The motherboard comes with six (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 figure illustrates the location of the DDR3 DIMM sockets:
2.4.2 Memory Configurations
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 configurations in this section.
• *Refer to ASUS Server AVL for latest update.
• Start installing the DIMMs from slot A1 and B1 (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.
