3.3 Socket 478 Processor
3.3.1 Installing Pentium 4 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 478.
Be 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 to
close the opened socket.
3.4 Main Memory
ECB-870 provides 3 DIMM sockets (168-pin Dual In-line Memory Module) to support 3.3V
SDRAM. The maximum memory size is 3GB (registered type of SDRAM). If 100MHz FSB
CPU is adopt, you have to use PC-100 SDRAM. For system compatibility and stability,
please do not use memory module without brand.
Both single and double-side DIMM module with ECC feature can be used on ECB-870.
And, it is not necessary to install the DIMM module in order. You can install different size
of SDRAM module on DIMM1, DIMM2, DIMM3 or all.
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.
