Intel Desktop Board D915GLVG Technical Product Specification

1.4 System Memory

The boards have four DIMM sockets and support the following memory features:
• 2.5 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. Refer to Section 2.2.1 on page 39 for information on the

total amount of addressable memory.

•  Minimum total system memory: 128 MB
•  Non-ECC DIMMs
•  Serial Presence Detect
•  DDR 400 MHz and DDR 333 MHz SDRAM DIMMs

Table 3 lists the supported system bus frequency and memory speed combinations.

Table 3.

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 throughput.

NOTES

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.
