2-1.2 Pentium 4 CPU Installation with Socket 478

This series is built with CPU Socket
478B (478-pin) supporting the Intel
Pentium 4 CPU:
• Follow the steps described in this
section to install the 478-pin Pentium
4 CPU into the on board Socket 478.
• After installation of Pentium 4 CPU,
you must also install the specific Pen-
tium 4 CPU fan designed in tandem
with this CPU. This CPU Fan instal-
lation is described in next section.
• This series supports Hyper-thread-
ing dual-in-one CPU, the function of
which can be enabled by Windows
XP. (See illustration on the right.)
1. First pull sideways the lever of
Socket 478, and then turn it up
0
90 so as to raise the upper layer
of the socket from the lower
platform.
2. Configure Pin 1 of CPU to Pin 1
of the Socket, just as the way
shown in the diagram on the right.
Adjust the position of CPU until
you can feel all CPU pins get into
the socket with ease.
3. Make sure that all CPU pins have
completely entered the socket
and then lower down the lever to
lock up CPU to socket.
( If Hyper-threading CPU is
installed successfully with O/S
Win XP, the O/S will enable the
dual-in-one CPU function.)
