Main Memory
The board supports 168-pin SDRAM DIMMs as defined below:
• 168-pin SDRAM Dual Inline Memory Modules (DIMMs) with gold-plated contacts
• Three DIMM slots are provided for flexible memory configurations
• 133 MHz SDRAM up to two double-sided DIMMs, or one double-sided DIMM and two
single-sided DIMMs
• 100 MHz SDRAM up to three double-sided DIMMs
• Minimum system memory: 32 MB
• Maximum system memory: 512 MB
✏
NOTE
The BIOS cannot determine DIMM size or type when not initialized. If more than 512 MB system
memory is installed, the BIOS displays a message at boot indicating some memory above 512 MB
has not been initialized. The message indicates additional information is available in Setup. The
first time BIOS detects this condition, a pause follows the message with the option to enter Setup or
to <ESC> and continue to boot. The message continues to be displayed at boot time as long as the
condition exists, however, the BIOS will not pause on subsequent detection. Setup displays the
installed memory configuration and shows memory above 512 MB as “not initialized.”
