2.5 System Memory
2.5.1 DIMM Sockets Location
The motherboard comes with one 204-pin Double Data Rate 3 (DDR3) SODIMM
sockets.
A DDR3 module has the same physical dimensions as a DDR DIMM but has a 204-
pin footprint. DDR3 DIMMs are notched differently to prevent installation on a DDR
DIMM socket. The following figure illustrates the location of the sockets:
2.5.2 Memory Configurations
You can install 1GB, 2GB and 4GB DDR3 DIMMs into the SODIMM sockets using
the memory configurations in this section.
Important!  Installing DDR3 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.
 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 syn-
chronization table.
