System Memory

System memory features
The Intel® Desktop Board D865GVHZ has two DIMM sockets and support 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.
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.

Supported system bus frequency and memory speed combinations

DIMM Required Processor System Bus Frequency
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.

System bus & memory speeds
The Intel® Desktop Board D865GVHZ supports three system bus speeds and three memory speeds. It is important to understand that not all system memory speeds are supported at all system bus speeds. In the table below, is a list of available system bus speeds and memory speeds capable.

System Bus Speed

PC2100
266 MHz DDR SDRAM

PC2700
333 MHz DDR SDRAM

PC3200
400 MHz DDR SDRAM

800 MHz x x1 x
533 MHz x x x2
400 MHz x x3 x4

1 To minimize system latencies and optimize system performance 333 MHz DDR memory is clocked at 320 MHz when using an Intel® Processor with an 800 MHz system bus speed.

2 To minimize system latencies and optimize system performance 400 MHz DDR memory is clocked at 333 MHz when using an Intel Processor with a 533 MHz system bus speed. Some memory modules may not work properly in this configuration.

3 To minimize system latencies and optimize system performance 333 MHz DDR memory is clocked at 266 MHz when using an Intel Processor with a 400 MHz system bus speed. Some memory modules may not work properly in this configuration.

4 To minimize system latencies and optimize system performance 400 MHz DDR memory is clocked at 266 MHz when using an Intel Processor with a 400 MHz system bus speed. Some memory modules may not work properly in this configuration.

Tested memory
