System Board Features

The following subsections describe the system board major components.
Processor
The processor board accommodates one to four 64-bit Intel® Xeon™ MP processors with 1 MB cache in an FC-PGA2
package.
DIMM Memory
To install or replace a DIMM, remove the memory board first.
One memory board is factory-installed in the server. Up to four memory boards (32 GB maximum) can be installed in
the server.
Install the DIMM (Dual Inline Memory Module) into the DIMM socket on the memory board of the server. DIMMs are
installed in the ascending order of DIMM socket numbers in the unit of two modules.
The controller automatically detects, sizes, and initializes the memory array, depending on the type, size, and speed of
the installed DIMMs, and reports memory size and allocation to the server via configuration registers.
NOTE:
Use DIMMs that have been provided by us. Contact your service representative or
dealer for a current list of approved memory modules.
