System Memory; Supported Memory Configurations - Intel BLKD945GCCR Specification

Intel Desktop Board D945GCCR Technical Product Specification
1.4

System Memory

The board has two DIMM sockets and supports the following memory features:
• 1.8 V (only) DDR2 SDRAM DIMMs with gold-plated contacts
• Unbuffered, single-sided or double-sided DIMMs with the following restriction:
Double-sided DIMMS with x16 organization are not supported.
• 2 GB maximum total system memory. Refer to Section 2.1.1 on page 41 for
information on the total amount of addressable memory.
• Minimum total system memory: 128 MB
• Non-ECC DIMMs
• Serial Presence Detect
• DDR2 533 or DDR2 400 MHz SDRAM DIMMs
NOTES
• Remove the PCI Express x16 video card before installing or upgrading memory to
avoid interference with the memory retention mechanism.
• To be fully compliant with all applicable DDR SDRAM memory specifications, the
board should be populated with 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, the BIOS will attempt to correctly configure the memory
settings, but performance and reliability may be impacted or the DIMMs may not
function under the determined frequency.
Table 3 lists the supported DIMM configurations.
