Tested Memory

Tested Memory
Memory testing has been performed under the following category:

Advanced Tested Memory †
Intel provides 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 tested by Computer Memory Test Labs (CMTL).

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

System Memory Features
Caution: Before installing or removing memory, make sure that AC power is disconnected by unplugging the power cord from the computer. Failure to do so could damage the memory and the board.

Note: To be fully compliant with all applicable Intel® SDRAM memory specifications, the board should be populated with DIMMs that support the Serial Presence Detect (SPD) data structure. If your memory modules do not support SPD, you will see a notification to this effect on the screen at power-up. The BIOS will attempt to configure the memory controller for normal operation. However, DIMMs may not function at the determined frequency.

Note: Because the main system memory is also used as video memory, the board requires 100 MHz SDRAM DIMM even though the host bus frequency is 66 MHz. It is highly recommended that an SPD DIMM be used, since 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.

The Intel® Desktop Board D815EGEW has two DIMM sockets and supports the following memory features:
  • 3.3 V (only) 168-pin SDRAM DIMMs with gold-plated contacts
  • Unbuffered Single- or double-sided DIMMs
  • Capacity:
    • Maximum system memory: 512 MB
    • Minimum system memory: 64 MB
  • 133 MHz SDRAM or 100 MHz SDRAM
  • Serial Presence Detect (SPD) and non-SPD memory
  • Non-ECC and ECC DIMMs (ECC DIMMs will operate in non-ECC mode only)
  • Suspend to RAM

When installing memory, note the following:
  • Non-SPD DIMMs will always revert to a 100 MHz with 3-3-3 timing SDRAM bus.
  • Mixing Non-SPD DIMMs with SPD DIMMs will always revert to a 100 MHz with 3-3-3 timing SDRAM bus.
  • The BIOS will not initialize installed memory above 512 MB. At boot, the BIOS displays a message indicating that any installed memory above 512 MB has not been initialized.
  • Mixed memory speed configurations (133 and 100 MHz) will default to 100 MHz.
  • 133 MHz SDRAM operation requires a 133 MHz system bus frequency processor.
  • 100 MHz SDRAM may be populated with six rows of SDRAM (three double-sided DIMMs).

    1 "DS" refers to double-sided memory modules (containing two rows of SDRAM) and "SS" refers to single-sided memory modules (containing one row of SDRAM).

    2 If the number of SDRAM devices is greater than nine, the DIMM will be double sided.

    3 Front side population / back side population indicated for SDRAM density and SDRAM organization.

All memory components and DIMMs used with the D815EGEW desktop board must comply with the PC SDRAM Unbuffered DIMM Specification. You can access this document through the Internet at: http://www.intel.com/technology/memory/index.htm
