System Memory



System memory features

The board has four DIMM sockets and support the following memory features:

  • 1.8 V (only) DDR2 SDRAM DIMMs with gold-plated contacts
  • Unbuffered, non-registered single 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: 512 MB
  • Non-ECC DIMMs
  • Serial Presence Detect
  • DDR2 800, DDR2 667, or DDR2 533 MHz SDRAM DIMMs

Note:
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 SDRAM Density SDRAM Organization Front-side/Back-side Number of SDRAM Devices
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 SS 1 Gbit 128 M x 8/empty 8
1024 MB DS 512 Mbit 64 M x 8/64 M x 8 16
2048 MB DS 1 Gbit 128 M x 8/128 M x 8 16

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).
Note:
Regardless of the DIMM type used, the memory frequency will either be equal to or less than the processor system bus frequency. For example, if DDR2 667 memory is used with a 533 MHz system bus frequency processor, the memory will operate at 533 MHz. The table below lists the resulting operating memory frequencies based on the combination of DIMMs and processors.

DIMM Type Processor system bus frequency Resulting memory frequency
DDR2 533 533 MHz 533 MHz
DDR2 533 800 MHz 533 MHz
DDR2 533 1066 MHz 533 MHz
DDR2 667 533 MHz 533 MHz
DDR2 667 800 MHz 667 MHz
DDR2 667 1066 MHz 667 MHz
DDR2 800 533 MHz 533 MHz
DDR2 800 800 MHz 800 MHz
DDR2 800 1066 MHz 800 MHz


Tested memory

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 was either tested by the memory vendor or by Intel using this test plan. These part numbers may not be readily available throughout the product life cycle.

The table below lists parts which passed testing conducted using Intel's Self Test program for the Intel® Desktop Board D945PDK.
