Installation Of The Cpu - Pentium SQ578 User Manual

Important: Do not use DIMM which use an extra TTL to convert the memory module from
asymmetric to symmetric.

Installation of the CPU

3.3
The SQ578 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 help 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 JP10,JP11,JP12,JP13,JP14,JP15,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 SQ578 mainboard.
