Intel Desktop Board D946GZIS Technical Product Specification
16
1.4
System Memory
The board has two 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 43 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
NOTE
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 3 lists the supported DIMM configurations.
