DDR2-SDRAM DIMMs
The memory sockets on the system board can be populated with up to four industry-standard
DIMMs. These memory module slots are populated with at least one preinstalled memory
module. To achieve the maximum memory support, you can populate the system board with up
to 4GB of memory configured in a high-performing dual channel mode.
For proper system operation, if the computer supports DDR2-SDRAM DIMMs, the DIMMs
must be:
■
industry-standard 240-pin
■
unbuffered PC 4200 533 MHz-compliant
■
1.8volt DDR2-SDRAM DIMMs
The DDR-SDRAM DIMMs must also:
■
support CAS latency 2.5 or 3 (CL = 2.5 or CL=3)
■
contain the mandatory JEDEC SPD information
In addition, the computer supports:
■
256Mbit, 512Mbit, AND 1 Gbit non-ECC memory technologies
■
single-sided and double-sided DIMMS
■
DIMMs constructed with x8 and x16 DDR devices; DIMMs constructed with x4 SDRAM
are not supported
DIMM Sockets
There are four DIMM sockets on the system board, with two sockets per channel. The sockets
are labeled XMM1, XMM2, XMM3, and XMM4. Sockets XMM1 and XMM2 operate in
memory channel A. Sockets XMM3 and XMM4 operate in memory channel B.
