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 supports the dual or single channel memory configurations defined below: • Four 240-pin Double Data Rate 3 (DDR3) SDRAM Dual Inline Memory Module (DIMM) connectors with gold-plated contacts. • 1333/1066/800 MHz DDR3 SDRAM interface • Unbuffered, non-registered single- or double-sided DIMMs • Non-ECC DDR3 memory • Serial Presence Detect (SPD) memory only • Up to 4 GB utilizing 512 Mb or 1 Gb technology • Up to 8 GB utilizing 1 Gb or 2 Gb technology NOTE System resources and hardware (such as PCI and 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. 13
