Note 2: DDR2 FBD 800 MHz memory is supported by the processors with FSB
1333 MHz and 1066 MHz; however, it will run @667 MHz.
Note 3: Due to the OS limitations, some operating systems may not show more
than 4 GB of memory.
Note 4: Due to memory allocation to system devices, memory remaining avail-
able for operational use will be reduced when 4 GB of RAM is used. The reduction
in memory availability is disproportional. Refer to the Memory Availability Table
below for details.
