System Memory Features

The Desktop Board D845PECE has two DIMM sockets and support the following memory features:

  • 2.5 V (only) 184-pin DDR SDRAM DIMMs with gold-plated contacts
  • Unbuffered, unregistered single-sided or double-sided DIMMs
  • Maximum total system memory: 2 GB; minimum total system memory: 64 MB
  • DDR333/266 MHz SDRAM DIMMs only
  • Serial Presence Detect (SPD)
  • Suspend to RAM

Caution
Do not use ECC DIMMs with these Desktop Boards. Using ECC DIMMs could damage the Desktop Board.

Integrator's Notes

  • Registered DIMMs are not supported.
  • Double-sided x16 DIMMs are not supported.
  • Remove the AGP video card before installing or upgrading memory to avoid interference with the memory retention mechanism.
  • The Desktop Board D845PECE has been designed to support DIMMs based on 512 Mbit technology for a maximum onboard capacity of up to 2 GB, but this technology has not been validated (currently validated up to 1.0 GB) on this board. Please refer to the latest lists of tested memory.

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.

The following table lists the supported DIMM configurations.

DIMM Capacity Configuration (Note 1) DDR SDRAM Density DDR SDRAM Organization Front-side/Back-side Number of DDR SDRAM Devices
32 MB SS 64 Mbit 4 M x 16/empty 4
64 MB SS 64 Mbit 8 M x 8/empty 8
64 MB SS 128 Mbit 8 M x 16/empty 4
128 MB DS 64 Mbit 8 M x 8/8 M x 8 16
128 MB SS 128 Mbit 16 M x 8/empty 8
128 MB SS 256 Mbit 16 M x 16/empty 4
256 MB DS 128 Mbit 16 M x 8/16 M x 8 16
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 8
1024 MB (Note 2) DS 512 Mbit 64 M x 8/64 M x 8 16

NOTES:

    1. In this column, "DS" refers to double-sided memory modules (containing DDR SDRAM devices on both sides) and "SS" refers to single-sided memory modules (containing DDR SDRAM devices on only one side).
    2. DDR333 1 GB (1024 MB) DIMMs have not been validated with this desktop board.
