Intel® Desktop Board D975XBX2
System memory

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

  • 1.8V and 1.9 V DDR2 SDRAM DIMMs
  • Unbuffered, single-sided, or double-sided DIMMs with the following restriction: Double-sided DIMMs with x16 organization are not supported.
  • 8 GB maximum total system memory
  • Minimum total system memory: 128 MB
  • ECC DIMMs and Non-ECC DIMMs
  • Serial Presence Detect
  • DDR2 800, DDR2 667, and DDR2 533 MHz SDRAM DIMMs
Note

Remove the Primary PCI Express* x16 (electrical x16 or x8) video card before installing or upgrading memory to avoid interference with the memory retention mechanism.

To be fully compliant with applicable DDR SDRAM memory specifications, the board should have DIMMs supporting the Serial Presence Detect (SPD) data structure. This structure 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 tries to correctly configure the memory settings. Performance and reliability can be impacted or the DIMMs might not function under the designated frequency.

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

Note
  1. In the second column, "DS" stands for double-sided memory modules (two rows of SDRAM) and "SS" stands for single-sided memory modules (one row of SDRAM).
  2. In the fifth column, the number in brackets specifies the number of SDRAM devices on an ECC DIMM.
Note 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 800 memory is used with a 533 MHz system Bus frequency processor, the memory works at 533 MHz. The table below lists the resulting working memory frequencies based on the combination of DIMMs and processors.
DIMM Type Processor system bus frequency Resulting memory frequency
DDR2 533 800 MHz 533 MHz
DDR2 533 1066 MHz 533 MHz
DDR2 667 800 MHz 667 MHz
DDR2 667 1066 MHz 667 MHz
DDR2 800 800 MHz 800 MHz
DDR2 800 1066 MHz 800 MHz

Tested memory

Third-party tested memory*
Third-party tested memory occurs as requested by the memory vendors and is tested at an independent memory location 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 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 that passed testing conducted using the Intel® Self Test program for Intel® Desktop Board D975XBX2.
