Intel® Desktop Board DG965PZ
System Memory

Updated: December 19, 2006

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, 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 using DDR2 667 or DDR2 533 DIMMs.
  • 4 GB maximum total system memory using DDR2 800 DIMMs.
  • Minimum total system memory: 512 MB.
  • Non-ECC DIMMs.
  • Serial Presence Detect.
  • DDR2 800, DDR2 667, or DDR2 533 MHz SDRAM DIMMs.
  • DDR2 800 DIMMs with SPD timings of only 5-5-5 or 6-6-6 (tCL-tRCD-tRP).
Note A minimum of 512 MB of system memory is required to fully enable both the onboard graphics and the manageability engine.
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 enables 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 Type SDRAM Technology Smallest usable DIMM (one x16 Single-sided DIMM) Largest usable DIMM (one x8 Double-sided DIMM) Maximum capacity with four identical x8 Double-sided DIMMs
DDR2 533 256 Mbit 128 MB 512 MB 2 GB
DDR2 533 512 Mbit 256 MB 1 GB 4 GB
DDR2 533 1 Gbit 512 MB 2 GB 8 GB
DDR2 667 256 Mbit 128 MB 512 MB 2 GB
DDR2 667 512 Mbit 256 MB 1 GB 4 GB
DDR2 667 1 Gbit 512 MB 2 GB 8 GB
DDR2 800 256 Mbit 128 MB 512 MB 2 GB
DDR2 800 512 Mbit 256 MB 1 GB 4 GB

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 800 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

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 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 Intel® Desktop Board DG965PZ.
