Intel Desktop Board D975XBX2 Technical Product Specification
18
1.4 System Memory
The board has four DIMM sockets and supports the following memory features:
• 1.8 V and 1.9 V DDR2 SDRAM DIMMs
• Unbuffered, single-sided or double-sided DIMMs with the following restriction:
Double-sided DIMMS with x16 organization are not supported.
• 8 GB maximum total system memory. Refer to Section 2.1.1 on page 49 for
information on the total amount of addressable memory.
• Minimum total system memory: 128 MB
• ECC DIMMs and non-ECC DIMMs
• Serial Presence Detect
• DDR2 800, DDR2 667, and DDR2 533 MHz SDRAM DIMMs
NOTES
• Remove the Primary PCI Express x16 (electrical x16 or x8) 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.
Table 4 lists the supported DIMM configurations.

Notes:
1.
In the second 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).
2. In the fifth column, the number in brackets specifies the number of SDRAM devices on an ECC DIMM.
