Installing The Processor
Installing a Pentium 4 processor in the mPGA478 Socket
is the simplest part of the procedure. It is very important,
however, to carefully handle the processor by the side
edges and always fully observe precautions against elec-
trostatic discharge. We assume here that you are install-
ing an Intel Pentium 4 boxed processor that comes with
a heatsink and Thermal Interface Material applicator. The
illustrations show these. If you are installing a non-boxed
processor, the procedure is the same, but the accessory
items may have a different appearance.
Please follow the installation procedure as illustrated on
the next two pages. The illustrations are generic and do
not specifically represent this motherboard.
The processor installation procedure is as follows:
1.Raise the locking lever of the processor locking
mechanism to a perpendicular position.
Raise the socket lever to the
vertical position
Step 1:
Raise the retaining lever
2. Align the processor to the socket by matching the
Pin 1 corner of the socket to the Pin 1 corner on the
socket, which is located at the corner where the
locking arm attaches to the socket.
Match the Pin 1 positions on
the socket and the processor
Step 2:
Align the Pin 1 corners
