Intel Desktop Board D865GBF/D865GLC Technical Product Specification 1.7 System Memory The Desktop Boards D865GBF and D865GLC have four DIMM sockets and support the following memory features: • 2.5 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. • 4 GB maximum total system memory. Refer to Section 2.2.1 on page 59 for information on the total amount of addressable memory. • Minimum total system memory: 64 MB • Non-ECC DIMMs • Serial Presence Detect • DDR400, DDR333, and DDR266 SDRAM DIMMs Table 5 lists the supported system bus frequency and memory speed combinations. Table 5. Supported System Bus Frequency and Memory Speed Combinations To use this type of DIMM... DDR400 The processor's system bus frequency must be... 800 MHz DDR333 (Note) 800 or 533 MHz DDR266 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. ✏ NOTES • Remove the AGP 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.

1.7 System Memory
The Desktop Boards D865GBF and D865GLC have four DIMM sockets and support the following
memory features:
•
2.5 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.
•
4 GB maximum total system memory.
Refer to Section 2.2.1 on page 59 for information on
the total amount of addressable memory.
•
Minimum total system memory:
64 MB
•
Non-ECC DIMMs
•
Serial Presence Detect
•
DDR400, DDR333, and DDR266 SDRAM DIMMs
Table 5 lists the supported system bus frequency and memory speed combinations.
Table 5.
Supported System Bus Frequency and Memory Speed Combinations
To use this type of DIMM…
The processor's system bus frequency must be…
DDR400
800 MHz
DDR333 (Note)
800 or 533 MHz
DDR266
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.
NOTES
•
Remove the AGP 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.
