3. On the Socket-370, identify the Pin-1 corner. The Pin-1 corner
is at the end of the locking lever when it is locked.
4. Match the Pin-1 corners and insert the processor into the
socket. No force is required and the processor should drop into
place freely.
5. Swing the locking lever down and hook it under the catch on
the side of the socket. This secures the CPU in the socket.
6. All processors should be installed with a combination heatsink/
cooling fan, connect the cable from the fan to the CPU fan
power connector FAN1.
Install Memory
The mainboard has two DIMM sockets for system memory
modules. You must install at least one memory module in order to
use the mainboard.
You must install the first memory module in
the DIMM1 socket to provide shared memory to the onboard
VGA display circuitry.
For this mainboard, you must use 168-pin, 3.3V unbuffered
SDRAM memory modules. If the installed CPU uses a 100MHz
system bus, you must use PC100 or PC133 memory. If the
installed CPU uses a 66MHz system bus, you must use PC66
memory. You can install any size memory module from 16 MB to
512MB, so the maximum memory size is 2 x 512MB = 1GB.
The edge connectors on the memory modules have cut outs, which
coincide with spacers in the DIMM sockets so that memory
modules can only be installed in the correct orientation.
