System Memory for the Intel® Desktop Board DG35EC





System memory features
The board has four DIMM sockets and supports the following memory features:

  • Four 240-pin Double Data Rate 2 (DDR2) SDRAM dual inline memory module
    (DIMM) connectors with gold-plated contacts
  • Non-ECC DDR2 800/667 1.8 V
  • Serial Presence Detect (SPD) memory only
  • Unbuffered, non-registered, single or double-sided DIMMs
  • Up to 2.0 GB utilizing 256 Mb technology
  • Up to 4.0 GB utilizing 512 Mb or 1 Gb technology
  • Up to 8.0 GB utilizing 1 Gb technology
Notes To be fully compliant with applicable Intel SDRAM memory specifications, the board requires DIMMs supporting the Serial Presence Detect (SPD) data structure. Desktop board DG35EC has four 240-pin DDR2 DIMM sockets arranged as DIMM 0 and DIMM 1 in both Channel A and Channel B.


Regardless of the memory configuration used (dual or single channel), Channel A, DIMM 0 must always be populated. This is a requirement of the ICH9DH Manageability Engine feature.

Supported DIMM configurations
The following table lists the supported DIMM configurations:

DIMM Type SDRAM Technology Smallest usable DIMM (one x16 Single-sided DIMM) Largest usable DIMM (one x8 Double-sided DIMM) Maximum capacity with two identical x8 Double-sided DIMMs
DDR2 667 512 Mbit 256 MB 1 GB 2 GB
DDR2 667 1 Gbit 512 MB 2 GB 4 GB
DDR2 800 512 Mbit 256 MB 1 GB 2 GB
DDR2 800 1 Gbit 512 MB 2 GB 4 GB


Tested memory

3rd party tested memory occurs as requested by the memory vendors. Memory is tested at an independent memory house that is not a part of Intel - Computer Memory Test Labs (CMTL).

Vendor self tested memory
Intel supplies the memory vendors that participate in this program with a common memory test plan to use as a basic checkout of the memory stability. Memory listed here was either tested by the memory vendor or by Intel using this test plan. These part numbers might not be readily available throughout the product life cycle.

The table below lists parts that passed testing conducted using the Intel Self Test program for Intel® Desktop Board DG35EC.
