Product Description # INTEGRATOR'S NOTE Use only ATX12V-compliant power supplies. For information about Power supply connectors Refer to Section 2.2.2.4, page 49 1.5 System Memory The board has two DIMM sockets and supports the following memory features: • 1.8 V DDR2 SDRAM DIMMs with gold plated contacts, with the option to raise the voltage to support higher performance DDR2 SDRAM DIMMs • Dual channel interleaved mode support • 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. Refer to Section 2.1.1 on page 39 for information on the total amount of addressable memory. • Minimum total system memory: 512 MB • Non-ECC DIMMs • Serial Presence Detect • DDR2 667 MHz or DDR2 800 MHz SDRAM DIMMs • DDR2 667 MHz DIMMs with SPD timings of only 5-5-5 (tCL-tRCD-tRP) • DDR2 800 MHz 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. Table 3 lists the supported DIMM configurations. Table 3.
