Installing a DIMM
The system motherboard comes with two Double Data Rate 2 (DDR2) Dual Inline
Memory Module (DIMM) sockets.
The following figure illustrates the location of the sockets:
• Installing DDR2 DIMMS other than the recommended configurations
may cause memory sizing error or system boot failure. Use any of the
recommended configurations in the table on the next page.
• Install only
identical
(the same type and size) DDR2 DIMMs in DIMM_A1
and DIMM_B1.
• Always install DIMMs with the same CAS latency. For optimum
compatibility, we recommend that you obtain memory modules from the
same vendor.
• Due to chipset resource allocation, the system may detect less than 2 GB
system memory when you installed two 1 GB DDR2 memory.
• This motherboard does not support memory modules made up of 128 Mb
chips or double-sided x16 memory modules.
