Product Description

1.6 System Memory

The Desktop Board D865GVHZ 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 4 lists the supported system bus frequency and memory speed combinations.

Table 4. 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

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.
