Intel DG41AN Product Specification - Page 16

Intel Desktop Board DG41AN Technical Product Specification The Desktop Board supports multiple processor and memory speeds. It is important to understand that not all memory speeds are supported with all processor speeds. Memory speed cannot exceed the Front Side Bus (FSB) speed of the processor. Table 3 lists the supported processor FSB and memory speeds. Table 3. Processor and Memory Speeds Processor FSB DDR3-800 Memory DDR3-1066 Memory DDR3-1066 Memory 800 MHz Memory runs at 800 MHz Memory runs at 800 MHz; cannot be overclocked Memory runs at 800 MHz; cannot be overclocked 1066 MHz Memory runs at 800 MHz; cannot be overclocked Memory runs at 1066 MHz Memory runs at 1066 MHz; cannot be overclocked 1333 MHz Memory runs at 800 MHz; cannot be overclocked Memory runs at 1066 MHz; cannot be overclocked Memory may be overclocked to 1333 MHz; memory runs at 1066 MHz 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 4 lists the supported DIMM configurations. Table 4.
