Intel® Desktop Board D945GCNL
System memory

System memory features
The board has two DIMM sockets and supports the following memory features:

  • 1.8V (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 667, 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.
  • Regardless of the DIMM type used, the memory frequency is either equal to or less than the processor system Bus frequency. For example, if DDR2 533 memory is used with an 800 MHz system Bus frequency processor, the memory works at 533 MHz.
  • To be fully compliant with applicable Intel® SDRAM specifications, the board should have DIMMs supporting the Serial Presence Detect (SPD) data structure. If your memory modules do not support SPD, a notification displays on the screen at power up. The BIOS tries to configure the memory controller for normal operation.

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

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

Note In the second column, “DS” stands for double-sided memory modules (two rows of SDRAM). “SS” stands for single-sided memory modules (one row of SDRAM).

Tested memory

3rd Party Tested Memory*
3rd party tested memory occurs as requested by the memory vendors and is tested at an independent memory house that is not a part of Intel - Computer Memory Test Labs (CMTL).

Vendor self tested memory
Intel supplies the memory vendors that participate in this program with a common memory test plan to use as a basic checkout of the memory stability. Memory listed here completed testing by the memory vendor or by Intel using this test plan. These part numbers might not be readily available throughout the product life cycle.

The table below lists parts which passed testing conducted using the Intel Self Test program for the Intel® Desktop Board D945GCNL.
