Installing System Memory
Your system has four 240-pin non-ECC DDR2 DIMM (Double Data Rate 2 Dual
In-line Memory Module) sockets to support a maximum of 4 GB.
Dual Channel Mode, instead of the default Single Channel Mode, can be enabled to
allow you to maximize the DIMMs performance. The installed DIMMs must meet the
following conditions:
z
Matched DIMM configuration
(channel A comprises DIMM1 and DIMM2 while channel B comprises DIMM3 and
DIMM4) :
– same density and DRAM technology in each channel
(e.g., 128 MB, 256 MB, 512 MB, 1 GB, etc.)
– same DRAM bus width (e.g., ×8 or ×16) in each channel
– both DIMM should be either single-sided or double-sided
NOTE:
z
The following conditions do not need to be met: same timing specifications and same
DDR2 speed.
z
Memory interface speed will be set to the slowest speed of DIMM populated.
z
Always install DIMMs with the same CAS latency. For optimum compatibility, it is
recommended that you obtain memory modules from the same vendor.
z
DIMM installed into any one slot will function in Single Channel Mode.
z
When the total DIMMs installed is over
4GB, only 4
GB
may be available for system
use due to chipset limitation.
z
Installing DIMMs other than the recommended configurations may cause memory
sizing error or system boot failure. Use any of the recommended configurations in the
next table.

Follow this procedure to install a DIMM:
1.
Open the cabinet cover (see previous section).
