Install A CPU

This mainboard has a Socket-478 that supports Intel Pentium 4
series processors.
To ensure reliability, ensure that your processor has a
heatsink/cooling fan assembly.
Do neither try to install a Socket 370 processor nor a Socket 423 in
the Socket-478. A Socket 370 processor such as the Pentium III, or
Celeron, does not fit in the Socket 478.
The following processor is currently supported by this mainboard.
Intel P4 478: 1.4GHz ~ 2.8GHz and up, FSB: 533MHz
Installing a Socket-478 Processor
A processor installs into the ZIF (Zero Insertion Force) Socket-478
on the mainboard.
1. Locate the Socket-478 and CPUFAN FAN1. Pull the locking
lever out slightly from the socket and raise it to the upright
position.
2. On the processor, identify the Pin-1 corner by its beveled edge.
3. On the Socket-478, identify the Pin-1 corner. The Pin-1 corner
is at the top of the locking lever when it 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.
