2.3.3 Support Components

Input/output functions not provided by the chipset are handled by other support components.
Some of these components also provide "housekeeping" and various other functions as well.
Table 2-3 shows the functions provided by the support components.
Component Name
SCH5327 SIO Controller
Broadcom BMC5754
Network Interface Controller
AD1884A HD Audio Codec
NOTE:
[1] COM2 requires optional bracket/cable assembly.
[2] LPTn support requires optional bracket/cable assembly.

2.3.4 System Memory

These systems implement a dual-channel non-ECC Double Data Rate (DDR2) memory
architecture. All models support DDR2 800- and 667-MHz DIMMs, and are shipped with DDR2
800-MHz (PC2-6400) DIMMs. These systems provide four DIMM sockets and support a total of
8 gigabytes of memory.
✎
DDR and DDR2 DIMMs are NOT interchangeable.
