1.11 System Memory
1.11.1 DIMM Sockets Location
The motherboard comes with two 240-pin Double Data Rate 2 (DDR2) Dual Inline
Memory Modules (DIMM) sockets.
A DDR2 module has the same physical dimensions as a DDR DIMM but has a 240-
pin footprint compared to the 240-pin DDR DIMM. DDR2 DIMMs are notched differ-
ently to prevent installation on a DDR DIMM socket. The following figure illustrates
the location of the sockets:
1.11.2 Memory Configurations
You can install 128 MB, 256 MB, 512 MB, 1GB and 2GB DDR2 SDRAM DIMMs into
the SODIMM sockets using the memory configurations in this section.
Note!
„
Installing DDR2 DIMM other than the recommended configurations
may cause memory sizing error or system boot failure. Use any of
the recommended configurations.
„
Always install DIMMs with the same CAS latency. For optimum
compatibility, it is recommended that you obtain memory modules
from the same vendor.
„
Due to chipset resource allocation, the system may detect less
than 1 GB system memory when you installed one 1 GB DDR2
memory modules.
„
This motherboard does not support memory modules made up of
128 MB chips or double-sided x16 memory modules.
„
Make sure that the memory frequency matches the CPU FSB
(Front Side Bus). Refer to the Memory frequency/CPU FSB
synchronization table.
