Intel Desktop Boards D925XECV2/D925XEBC2 Technical Product Specification 1.6 System Memory The boards have four DIMM sockets and support the following memory features: • 1.8 V and 1.9 V DDR2 SDRAM DIMMs • 3-3-3 memory timing with 1.9 V DIMMs • 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 55 for information on the total amount of addressable memory. • Minimum total system memory: 128 MB • Non-ECC DIMMs • Serial Presence Detect • DDR2 533 MHz or DDR2 400 MHz SDRAM DIMMs NOTES • The BIOS will recognize 1.9 V DIMMs (via the SPD data structure) and reconfigure the memory voltage regulator circuit for 1.9 V, 3-3-3 memory timing operation. • 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. Table 6 lists the supported DIMM configurations. Table 6.
