System Memory; Supported Memory Configurations - Intel BOXD945GBOLKR Technical Product Specification

Intel Desktop Board D945GBO Technical Product Specification

1.5 System Memory

The board has four DIMM sockets and support the following memory features:
•
1.8 V (only) DDR2 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 2.1.1 on page 45 for information on the
total amount of addressable memory.
•
Minimum total system memory: 128 MB
•
Non-ECC DIMMs
•
Serial Presence Detect
•
DDR2 667 or DDR2 533 MHz SDRAM DIMMs
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.
Table 4 lists the supported DIMM configurations.
