Intel Desktop Board DG41RQ Product Guide Main Memory 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. The Desktop Board has two DIMM sockets that support the memory features listed below: • 1.8 V DDR2 SDRAM DIMMs with the option in the BIOS setup to raise the voltage to support higher performance DDR2 SDRAM DIMMs • Support for: ⎯ Non-ECC DDR2 800/667 MHz memory ⎯ Serial Presence Detect (SPD) memory only ⎯ Unbuffered, non-registered single- or double-sided DIMMs ⎯ Memory configurations listed below: • Up to 2.0 GB utilizing 256 Mb technology • Up to 8.0 GB utilizing 512 Mb or 1 Gb technology • A minimum of 512 MB of total memory is required NOTE System resources and hardware (such as PCI Express) require physical memory address locations that can reduce available addressable system memory. This could result in a reduction of as much as 1 GB or more of physical addressable memory being available to the operating system and applications, depending on the system configuration and operating system.
