System Installation
ROBO-8714VG2A User’s Manual
3-2
3) Push down the lever to lock processor chip into the socket once CPU fits.
4) Follow the installation guide of cooling fan or heat sink to mount it on CPU
surface and lock it on the socket 478.
Removing CPU
1) Unlock the cooling fan first.
2) Lift the lever of CPU socket outwards and upwards to the other end.
3) Carefully lifts up the existing CPU to remove it from the socket.
4) Follow the steps of installing a CPU to change to another one or place handling
bar to close the opened socket.
Configuring System Bus
ROBO-8714VG2A will automatically detect the CPU used. CPU speed of Intel P4 can
be detected automatically.
3.2 Main
Memory
ROBO-8714VG2A provides ECC function for data sensitive application. Two 184-pin
DIMM sockets support DDR-SDRAM as main memory. The maximum memory size
can be Up to 2GB DDR 400/333/266 SDRAM. Auto detecting memory clock
according to BIOS CMOS settings.
For system compatibility and stability, don’t use memory module without brand.
You can also use only one double-sided DIMM in either one DIMM socket or two
single-sided DIMM in both sockets.
Watch out the contact and lock integrity of memory module with socket, it will
impact on the system reliability. Follow normal procedures to install your DRAM
module into memory socket. Before locking, make sure that all modules have been
fully inserted into the card slots.
Dual Channel DDR DIMMs
Dual Channel DDR memory technology doubles the bandwidth of memory bus.
Adequate or higher bandwidth of memory than processor would increase system
performance. To enable Dual Channel DDR memory technology, you have to
install dual identical memory modules in both memory sockets. Following tables
show bandwidth information of different processor and memory configurations.
CPU FSB
Bandwidth
800MHz 6.4GB/s
533MHz 4.2GB/s
400MHz 3.2GB/s
