Architecture
ROBO-8120VG2R adopts Intel
®
single or dual Dual-Core™/Quad-Core™ Xeon
®
C5500/C3500 series processors in LGA1366 package and 3420 server chipset. Intel
®
Xeon
®
processors support ECC & registered DDR3 1333/1066/800 system memory
up to 32GB on four DIMM sockets, and two configurable PCI Express x8 links. The
PCI Express link was configured as four PCI Express x4 and one PCI Express x16 thru
BIOS and jumper setting. Two PCI Express x1 links were used to equip Intel
®
82574L
Gigabit Ethernet Controller which takes advantage of short route to processor and
memory to increase it performance. The other three PCI Express x4 and PCI Express
x8 links are routed to gold finger for external expansion.
3420 supports one PCI bus which was designed to support external PCI devices and
PCI-E x1 bus was for on-board display controller – XGI Z11. XGI Z11 default
equipped with 32MB DDR2 memory on-board and scalable to expand to 64MB for
higher memory resolution and frequency support. Default configuration of display
interface is one VGA connector on bracket, and it can be extended to have 2
nd
VGA or
DVI-D extension. The chipset also features SATA, USB and LPC (Low Pin Count)
interface for storage devices and Super I/O connections.
Super I/O – Winbond W83627DHG on LPC provides I/O interfaces such as PS/2
keyboard/mouse, dual serial ports, one parallel port, one FDD channel and functions
like WatchDog timer and Hardware Monitoring.
