Intel® Desktop Board D915GMH
System memory

System Memory Features
The board has four DIMM sockets and support the following memory features:

  • 2.6 V (only) 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.
  • 4 GB Maximum total system memory
  • Minimum total system memory: 128 MB
  • Non-ECC DIMMs
  • Serial Presence Detect
  • DDR 400 MHz and DDR 333 MHz SDRAM DIMMs

Notes:

  • Remove the PCI Express* x16 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.

Integrator's Note
It is possible to install four 2048 MB (2 GB) modules for a total of 8 GB of system memory, however, only 4 GB of address space is available.


Supported system bus frequency and memory speed combinations

To use this type of DIMM. . . The processor's system bus frequency must be. . .
DDR 400 800 MHZ
DDR 333 (Note) 800 or 533 MHz

Note:
When using an 800 MHz system bus frequency processor, DDR 333 memory is clocked at 320 MHz. This minimizes system latencies to optimize system thoughput.

In this 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).


Tested Memory


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 D915GMH.
