Intel® Desktop Board D945PLNM
System Memory

Updated: April 13, 2006

System memory features
The board has two DIMM sockets and support 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.
  • 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.

Supported DIMM configurations
The following table lists the supported DIMM configurations.

DIMM Capacity Configuration (Note) SDRAM Density SDRAM Organization Front-side/Back-side Number of SDRAM Devices
128 MB SS 256 Mbit 16 M x 16/empty 4
256 MB SS 256 Mbit 32 M x 8/empty 8
256 MB SS 512 Mbit 32 M x 16/empty 4
512 MB DS 256 Mbit 32 M x 8/32 M x 8 16
512 MB SS 512 Mbit 64 M x 8/empty 8
512 MB SS 1 Gbit 64 M x 16/empty 4
1024 MB DS 512 Mbit 64 M x 8/64 M x 8 16
1024 MB SS 1 Gbit 128 M x 8/empty 8

Note:
In the second column, "DS" refers to double-sided memory modules (containing two rows of SDRAM) and "SS" refers to single-sided memory modules (containing one row of SDRAM).
