System Memory Features

The boards have four DIMM sockets and support the following memory features:

  • 1.8 V and 1.9 V DDR2 SDRAM DIMMs
  • Unbuffered, single-sided, or double-sided DIMMs with the following restriction: Double-sided DIMMs with x16 organization not supported
  • 8 GB maximum total system memory
  • Minimum total system memory: 128 MB
  • ECC DIMMs and non-ECC DIMMs
  • Serial Presence Detect
  • DDR2 667 and 533 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 comply with applicable DDR SDRAM memory specifications, populate the board 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 attempts to correctly configure the memory settings. However, 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

256 MB SS 256 Mbit 32 M x 8/empty 8 [9]
256 MB SS 512 Mbit 32 M x 16/empty 4 [5]
512 MB DS 256 Mbit 32 M x 8/32 M x 8 16 [18]
512 MB SS 512 Mbit 64 M x 8/empty 8 [9]
512 MB SS 1 Gbit 64 M x 16/empty 4 [5]
1024 MB DS 512 Mbit 64 M x 8/64 M x 8 16 [18]
1024 MB SS 1 Gbit 128 M x 8/empty 8 [9]
2048 MB DS 1 Gbit 128 M x 8/128 M x 8 16 [18]
Notes
  1. 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).
  2. In the fifth column, the number in brackets specifies the number of SDRAM devices on an ECC DIMM.

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). In the fifth column, the number in brackets specifies the number of SDRAM devices on an ECC DIMM.

Tested Memory

Third-party tested memory*
Third-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. The test plan checks the memory stability. The memory vendor or Intel tested memory listed here, 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 Intel® Desktop Board D975XBX.
