Memory
The system board has six 168-pin DIMM slots each supporting 72-bit ECC registered DDR
DIMMs (DDR266 compatible). Memory is partitioned in three banks. A minimum of 256 MB
(128 MB x 2) and as much as 12 GB may be installed. Memory must be installed in pairs, starting
with bank 1 (slots 1B and 1A).
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 tested for compatibility with the server board.
Contact your sales representative or dealer for a current list of approved
memory modules.
PCI Riser Slots
The server board has two PCI riser slots. The Segment B PCI adapter subsystem provides the
following features:
•
184-pin, 5-volt keyed, 64-bit expansion slot connector
•
Support for a 3-slot PCI riser card
•
Support for both 5-volt and 3.3-volt PCI riser cards
The Segment C PCI adapter subsystem provides the following features:
•
184-pin, 5-volt keyed, 64-bit expansion slot connector
•
Support for a 3-slot PCI riser card
•
Support for only low-profile 3.3-volt PCI riser cards
•
RADIOS enabled for use with zero channel RAID cards (SCSI version only)
Video
The server board uses an ATI* RAGE XL PCI graphics accelerator with 8 MB of video SDRAM.
The embedded SVGA video subsystem supports:
•
Resolutions up to 1600 x 1200 under 2D and 1024 x 768 under 3D
•
CRT and LCD monitors up to 100-Hz vertical refresh rate
The server board supports disabling of the onboard video through the BIOS setup menu or when a
plug-in video card is installed in any of the PCI slots.
SCSI Controller
The SCSI version of the server board includes an embedded Adaptec* AIC-7902W controller
providing dual Ultra-320 Low Voltage Differential (LVD) SCSI channels.
The SCSI bus is terminated on the server board with active terminators that cannot be disabled.
The onboard device must always be at one end of the bus. The device at the other end of the cable
must also be terminated. LVD devices generally do not have termination built-in and need to have
a termination source provided. Non-LVD devices generally are terminated through a jumper or
resistor pack on the device itself.
