System memory

System memory features
The Intel® Desktop Board D865PERL has four DIMM sockets and supports the following memory features:

  • 2.5V and 2.6V 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
  • Minimum total system memory: 64 MB
  • Non-ECC DIMMs
  • Serial presence detect
  • DDR400, DDR333, and DDR266 SDRAM DIMMs
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 DDR SDRAM memory specifications, the board should have DIMMs supporting the serial presence detect (SPD) data structure. This board 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 tries to correctly configure the memory settings. But, performance and reliability can be impacted or the DIMMs might not function under the designated frequency.


Supported system bus frequency and memory speed combinations

DIMM Required Processor System Bus Frequency
DDR400 800 MHz
DDR333 800 or 533 MHz (Note)
DDR266 800, 533, or 400 MHz
Note When using an 800 MHz system bus frequency processor, DDR333 memory is clocked at 320 MHz minimizing system latencies for optimum system throughput.

System bus and memory speeds
The Intel® Desktop Board D865PERL 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 1
533 MHz 2
400 MHz 3 4

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.

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.

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.


Tested memory

Third-party tested memory*
Intel offers the advanced environmental test procedures, test software, and necessary hardware to an independent test lab to perform advanced testing as requested by the memory vendors.
Memory is tested by Computer Memory Test Labs (CMTL*).

Internal tested memory
Intel has a limited amount of memory tested for the desktop board. These part numbers might not be readily available throughout the product life cycle.
