3) Insert the DIMM into the DIMM socket at a 90 degree angle. If pin 1 of the DIMM does
not line up with pin 1 of the socket, the DIMM will not insert into the socket. After
inserting the DIMM completely into the socket, push up on the socket latches securing
the DIMM into place.
4) To release the memory modules, push both latches down and carefully rock the module
forward
Important: Do not use DIMM which use an extra TTL to convert the memory module from
asymmetric to symmetric.
3.3 Installation of the CPU
The SQ575 comes with a 321-pin ZIF socket 7 for installing the CPU. The Socket 7 will also
support future Pentium up-grade processors. It is strongly recommended that a heatsink and
CPU cooling fan be used to prevent the CPU from overheating. (Tip) Applying a thermal jelly
between the CPU and the heatsink/fan will cool the CPU.
To install a CPU, remember to take the following precautions against static electric discharge.
The basic procedure is as follows:
NOTICE: When installing the CPU into the CPU socket, be sure that PIN 1 of the CPU is in
the same corner as PIN 1 of socket. The CPU is an extremely sensitive electrical component
and can be easily damaged by static electricity.

IMPORTANT: you must set jumpers JP6, JP7, JP13, JP14, JP15 and JP16 to correct
CPU Voltage.
1) Turn off your system and disconnect the power source.
2) Remove the existing CPU from the ZIF socket by pulling the ZIF lever upwards at a 90
degree angle.
3) Insert the CPU with the correct orientation as shown below. Use the notched (white dot)
corner of the CPU as your guide. The notch in the corner of the CPU should correspond
with PIN 1 of the ZIF socket (Notice: Pin 1 is the blank corner of the ZIF socket with
one hole missing).
4) Once the CPU is inserted close the socket’s lever.
WARNING: Without a fan, the CPU can overheat and will cause damage to both the CPU
and the SQ575 mainboard.
