Intel® Desktop Board D865PCD
System Memory

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

  • 2.5 V (only) 184-pin DDR 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: 64 MB.
  • Non-ECC DIMMs.
  • Serial Presence Detect.
  • DDR333 and DDR266 SDRAM DIMMs.

Notes

  • Remove the AGP video card before installing or upgrading memory to avoid interference with the memory retention mechanism.
  • 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 system bus frequency and memory speed combinations

To use this type of DIMM... The processor's system bus frequency must be...
DDR333(Note) 533 MHz
DDR266 533 or 400 MHz

Note:
When using an 800 MHz system bus frequency processor, DDR333 memory is clocked at 320 MHz. This minimizes system latencies to optimize system throughput.

1024 MB DS 512 Mbit 64 M x 8/64 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).
