The motherboard has three Dual Inline Memory Module (DIMM) sockets. Minimum memory size is 8 megabytes (MB); maximum size is 384 MB. The basic input/output system (BIOS) automatically detects memory type, size, and speed.

Memory can be installed in one, two or three sockets. Memory type, size and speed can vary between sockets. Bank 0 is toward the back of the board, next is bank 1, then bank 2.

The motherboard supports the following memory features:

• 168-pin DIMMs with gold-plated contacts
  
• Unbuffered synchronous DRAM (SDRAM)
  
  • Synchronous DRAM improves memory performance through memory access that is synchronous with the memory clock. This simplifies the timing design and increases memory speed because all timing is dependent on the number of memory clock cycles. The SDRAM should also meet the PC SDRAM Unbuffered DIMM Specification for either 64-bit or 72-bit SDRAM.
    
  • Memory Error Checking and Correction (ECC) is a powerful feature designed to detect memory errors as they occur without interrupting computer operation.
    
    • ECC memory detects multiple-bit errors when two or more bits have failed and corrects single-bit errors when a single bit has failed.
      
    • When ECC memory is installed, the BIOS supports both ECC and non-ECC mode. ECC mode is enabled in the BIOS Setup Utility.
      
    • The BIOS automatically detects if ECC memory is installed and provides the setup option for selecting ECC mode.
      
• 66- or 100-megahertz (MHz) SDRAM only
  • Processors with a 100-MHz front side bus (FSB) should only be used with 100-MHz random access memory (RAM).
  • Processors with a 66-MHz FSB can be used with 100- or 66-MHz RAM.
• Non-ECC, 64-bit, and ECC, 72-bit, memory
  
• 3.3V memory only
  
• Single or double-sided DIMMs in the following sizes:
