System Installation
ROBO-8773VG User’s Manual
3-3
Precaution! (See fig.3-3) Don’t touch directly by your hand or impacts internal align
balls of CPU socket to avoid motherboard destruction, it is a precise actuator.
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 LGA 775.
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-8773VG will automatically detect the CPU used. CPU speed of Intel P4 can be
detected automatically.
3.2 Main
Memory
ROBO-8773VG provides two DDR-SDRAM DIMM sockets to support 333/400 DDR-
SDRAM as main memory, Non-ECC, non-buffered DIMMS only. The maximum
memory size can be up to 2GB. Auto detecting memory clock in according to BIOS
CMOS settings.
For system compatibility and stability, do not use memory module without brand.
Memory configuration can be either 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 memory
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, install two
identical memory modules in both memory sockets is required. Following tables
show bandwidth information of different processor and memory configurations.
