Intel Desktop Board D915GMH Technical Product Specification 1.6 System Memory The board has 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 53 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 4 lists the supported system bus frequency and memory speed combinations.

1.6
System Memory
The board has 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 53 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 4 lists the supported system bus frequency and memory speed combinations.
Table 4.
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
•
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.
