System Memory Features

The Desktop Board D845PEBT2 has two DIMM sockets and supports 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 with the following restriction:
    Double-sided DIMMsS with x16 organization are not supported
  • 2 GB maximum total system memory with the following clarification:
    The Desktop Board 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 on this Desktop Board. Please refer to the latest lists of tested memory.
  • Minimum total system memory: 64 MB
  • Non-ECC DIMMs
  • Serial Presence Detect
  • Suspend to RAM
  • 333/266 MHz DDR 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 Desktop 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.

The following table lists the supported DIMM configurations.

DIMM Capacity Configuration DDR SDRAM Density DDR SDRAM Organization Front-side/Back-side Number of DDR SDRAM Devices
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/empty 8
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 DDR SDRAM) and "SS" refers to single-sided memory modules (containing one row of DDR SDRAM).
