Intel Desktop Board D865GSA Technical Product Specification
1.4 System Memory
The board has two DIMM sockets and supports the following memory features:
• 2.6 V (only) 184-pin 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.
• 2 GB maximum total system memory.
• Minimum total system memory: 64 MB
• Non-ECC DIMMs
• Serial Presence Detect
• DDR400, DDR333, and DDR266 SDRAM DIMMs
Table 3 lists the supported system bus frequency and memory speed combinations.
Table 3. Supported System Bus Frequency and Memory Speed Combinations
To use this type of DIMM… The processor's system bus frequency must be…
DDR400
DDR333 (Note)
DDR266
800 MHz
800 or 533 MHz
800, 533, or 400 MHz
Note: When using an 800 MHz system bus frequency processor, DDR333 memory is clocked at 320 MHz.
This minimizes system latencies to optimize system throughput.
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 enables 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.
