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:

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!
GMB-910 User Manual
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.
