System Board Features
The following subsections describe the system board major components.
Processor
The processor board accommodates one to four 64 bit Intel Xeon processor MP or Dualcore Intel
Xeon processor in the FC-PGA2 package.
DIMM Memory
To install or replace the DIMM, remove the memory board first.
One memory board is factory-installed in the server. Up to four memory boards (64GB at the
maximum) can be installed in the server.
Install the DIMM (Dual Inline Memory Module) to the DIMM socket on the memory board in 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 NEC. Contact your
service representative or dealer for a current list of approved memory
modules.
Onboard Video
The I/O board incorporates an ATI RADEON7000M graphics accelerator with 16 MB of video
SDRAM that supports all standard IBM VGA modes. The embedded SVGA video subsystem
supports:
Pixel resolutions up to 1024 × 768
CRT and LCD monitors up to 100 Hz vertical refresh rate
The I/O board supports disabling of the onboard video through BIOS Setup or when a plug-in video
card is installed in any of the PCI slots.
