System Overview
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.
NOTE:
[1] COM2 requires external bracket/cable assembly.
[2] Requires external bracket/cable assembly.
2.3.4 System Memory
These systems implement a dual-channel Double Data Rate (DDR3) memory architecture. All
models support DDR3 1333-, 1066, and 800-MHz memory modules and provide four UDIMM
sockets and support a total of 16 gigabytes of memory.
