Intel Desktop Board DG35EC Technical Product Specification # INTEGRATOR'S NOTE Use only ATX12V-compliant power supplies. For information about Power supply connectors Refer to Section 2.2.2.4, page 46 1.5 System Memory The board has four DIMM sockets and supports the following memory features: • 1.8 V (only) DDR2 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. • 8 GB maximum total system memory. Refer to Section 2.1.1 on page 37 for information on the total amount of addressable memory. • Minimum total system memory: 512 MB • Non-ECC DIMMs • Serial Presence Detect • DDR2 667 or DDR2 800 MHz SDRAM DIMMs • DDR2 667 DIMMs with SPD timings of only 5-5-5 (tCL-tRCD-tRP) • DDR2 800 DIMMs with SPD timings of only 5-5-5 or 6-6-6 (tCL-tRCD-tRP) 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 enables 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.

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 enables 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.
