4.5.3 DIMM Module Installation
4.5.3.1 Purchasing the Memory Module
WARNING:
When purchasing the DIMM modules, make sure the modules are
compatible with the DIMM slot specified in Section 2.6 Memory
Support.
WARNING:
The board supports DDR2 DIMM modules only. DDR1 and DDR2 are
not compatible. If a DDR1 DIMM module is installed, the system may
be damaged and become inaccessible. Please only use DDR2 DIMM
modules.
When you purchase your DIMM modules, the following considerations should be taken
into account:
Each DIMM socket can support DIMM modules with a maximum size of 1GB
Only use DDR2 memory chips in the DIMM slots
It is recommended that you use memory modules of identical brand, size,
chips, and speed.
DIMMs must use the same density memory chips
Both DIMMs must use the same DRAM bus width
Both DIMMs must be either single-sided or dual-sided
