Intel Desktop Board D2550DC2 Technical Product Specification

1.4 System Memory
The board has two 204-pin DDR3 SO-DIMM sockets and supports the following
memory features:
• DDR3 SDRAM SO-DIMMs with gold-plated contacts
• Unbuffered, single-sided or double-sided DIMMs
• 4 GB maximum total system memory
• Minimum total system memory: 256 MB
• Non-ECC DIMMs
• Serial Presence Detect
• DDR3 1066 MHz, DDR3 1333 MHz, DDR3 1600 MHz SO-DIMMs
(DDR3 1333 MHz and DDR3 1600 MHz memory will run at 1066 MHz)
NOTES
• Due to passively-cooled thermal constraints, system memory must have an
operating temperature rating of 85
o
C.
The board is designed to be passively cooled in a properly ventilated
chassis. Chassis venting locations are recommended above the system
memory area for maximum heat dissipation effectiveness.
• If you are installing only one SO-DIMM, it must be installed in the bottom
socket (SO-DIMM 1).
• To be fully compliant with all applicable DDR3 SDRAM memory
specifications, the board should be populated with SO-DIMMs that support
the Serial Presence Detect (SPD) data structure. This allows the BIOS to
read the SPD data and program the chipset to accurately configure memory
settings for optimum performance. If non-SPD memory is installed,
performance and reliability may be impacted or the SO-DIMMs may not
function under the determined frequency.
Table 3 lists the supported SO-DIMM configurations.
