3.3 Socket 370 Processor
3.3.1 Installing Pentium III / Celeron CPU
Lift the handling lever of CPU socket outwards and upwards to the other end.
Align the processor pins with pin holes on the socket. Make sure that the notched
corner or dot mark (pin 1) of the CPU corresponds to the socket’s bevel end.
Then press the CPU gently until it fits into place. If this operation is not easy or
smooth, don’t do it forcibly. You need to check and rebuild the CPU pin uniformly.
Push down the lever to lock processor chip into the socket.
Follow the installation guide of cooling fan or heat sink to mount it on CPU
surface and lock it on the socket 370.
Make sure to follow particular CPU speed and voltage type to adjust the jumper
settings properly.
3.3.2 Removing CPU
Unlock the cooling fan first.
Lift the lever of CPU socket outwards and upwards to the other end.
Carefully lift up the existing CPU to remove it from the socket.
Follow the steps of installing a CPU to change to another one or place handling
bar back to close the opened socket.
3.4 Main Memory
ECB-862 provides two SDRAM socket (168-pin Dual In-line Memory Module) to support
3.3V SDRAM. The maximum memory size is 512MB. If 133MHz FSB CPU is adopted, you
have to use PC-133 compliant SDRAM. For system compatibility and stability, please do
not use memory module without brand.
Watch out the contact and lock integrity of memory module with socket, it will influence the
system’s reliability. Follow the normal procedure to install your SDRAM module into the
DIMM socket. Before locking the DIMM module, make sure that the memory module has
been completely inserted into the DIMM socket.
Note:
Please do not change any SDRAM parameter in BIOS setup to increase your
system’s performance without acquiring technical information in advance.
