Main Memory; Ecc Memory; Supported Dimm Sizes And Configurations For Cc820 (Non-Ecc Specified) - Intel cc820 Product Manual

Main Memory

The CC820 desktop board has two DIMM sockets supporting 168-pin SDRAM DIMMs as defined
below. Also note that when installing memory in the CC820 desktop board, proper memory
installation guidelines must be followed as defined on Page 26.
The CC820 desktop board supports the following memory features:
•
168-pin SDRAM DIMMs with gold-plated contacts
•
100 MHz SDRAM (only)
•
64 Mbit and 128 Mbit SDRAM component density (see Table 4 below)
•
Minimum system memory: 32 MB
•
Maximum system memory: 512 MB
•
Unbuffered single or double-sided DIMMs
•
Serial Presence Detect (SPD) memory (only)
•
Non-ECC and ECC DIMMs (ECC DIMMs will operate in non-ECC mode only)
•
3.3 V memory (only)
•
Suspend to RAM
CAUTION
To be fully compliant with all applicable Intel
requires DIMMs that support the Serial Presence Detect (SPD) data structure. If non-SPD
DIMMs are installed, the system will not boot properly.

component for each side of DIMM

ECC Memory

The CC820 board supports both ECC and non-ECC DIMMs (ECC DIMMs will operate in non-
ECC mode only).
