      Important Notes System Memory Combinations
      The Intel® Desktop Board CC820 has two, dual inline memory module (DIMM) sockets. Minimum memory size is 32 MB; maximum memory size is 512 MB. The BIOS automatically detects memory type, size, and speed. A Memory Translator Hub (MTH) is used to translate the Rambus* channel of the Intel® 820 chipset to SDRAM memory.

      The motherboard supports the following memory features:
      • 168-pin SDRAM DIMMs with gold-plated contacts
      • 100 MHz SDRAM (only)
      • Non-ECC (64-bit) memory
      • 64 Mbit and 128 Mbit SDRAM component density (see table below)
      • 3.3 V memory (only)
      • Serial Presence Detect (SPD) memory (only)
      • Non-ECC and ECC DIMMs (ECC DIMMs will operate in non-ECC mode only)
      • Unbuffered Single- or double-sided DIMMs in the following sizes:

      Supported DIMM Sizes and Configurations (non-ECC specified)
      DIMM Size Total Number of SDRAM Components on DIMM Non-ECC DIMM Organization SDRAM Component Density SDRAM Component Organization
      32 MB 4 4M x 64 64 Mbit 4M x 16
      64 MB 8 8M x 64 64 Mbit 8M x 8
      64 MB 8 (double sided) 8M x 64 64 Mbit 4M x 16
      64 MB 4 8M x 64 128 Mbit 8M x 16
      128 MB 16 (double sided) 16M x 64 64 Mbit 8M x 8
      128 MB 8 16M x 64 128 Mbit 16M x 8
      128 MB 8 (double sided) 16M x 64 128 Mbit 16M x 8
      256 MB 16 (double sided) 32M x 64 128 Mbit 16M x 8
      Important Note: The Intel Desktop Board CC820 will not accept all DIMM configurations. DIMMs must be installed using the DIMM configuration guidelines. When installing DIMMs in the Intel Desktop Board CC820, you must use the memory installation guidelines as described in the following table.

      Due to the demands of today's software applications, a minimum of 64 MB of system memory is recommended.

      DIMM Installation Guidelines
      Types of DIMMs to be installed Bank 0 Bank 1
      One DIMM DIMM Empty
      Two DIMMs - Same size, same number of sides (both single or both double sided) Either DIMM Either DIMM
      Two DIMMs - Different sizes Larger DIMM Smaller DIMM
      Two DIMMs - Same size, one is single-sided and one is double-sided Single-sided DIMM Double-sided DIMM


      All memory components and DIMMs used with the Intel Desktop Board CC820 must comply with the PC SDRAM Unbuffered DIMM Specification. You can access this document through the Internet at:

      DIMM Vendors - SDRAM Non-ECC DIMMs
      The table below lists parts which passed either BASIC or FULL testing conducted by third-party memory vendors for the Intel Desktop Board CC820. These part numbers will be removed and replaced by Intel FULL tested part numbers approximately one week after the Intel® Desktop Board CC820 is released. After the part numbers are removed, parts tested by third-party DIMM vendors can be found under the list of "DIMM Vendors - Web Sites" section above. For a complete explanation of FULL and BASIC testing see the Desktop Board Component Functional Testing Levels page.
