Overview
The motherboard comes with four (for CPU1) and four (for CPU2) 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.
2.4.2
Memory Configurations
You may install 1GB, 2GB, 4GB, 8GB and 16GB* 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.
