Pentium™4 Socket 423 to Pentium™4/P4-Celeron™Socket 478 Upgrade Adapter
The PL-P4/N™ is a unique Socket 423 to Socket 478 CPU upgrade adapter; it will automatically set the appropriate core voltage
and multiplier for your new Socket 478 Pentium™ 4 or P4-Celeron CPU.
The PL-P4/N™supports the “Northwood” core-based Socket 478 Pentium™4 (512KB L2 cache) CPUs, the “Willamette”
core-based Socket 478 Intel Pentium™ 4 (256KB L2 cache) and the P4-Celeron™(128KB L2 cache, 1.7GHz and up) CPUs.
To insert a new Socket 478 Pentium™ 4 or P4-Celeron CPU into the PL-P4/N™:
1. Place your new Intel Pentium™ 4/Celeron CPU into the 478-pin ZIF (Zero Insertion Force) socket on the PL-P4/N™
adapter. You need to lift the arm of the ZIF socket up to accommodate the CPU, and then put the arm down to lock it.
2. Verify that the pin 1 alignment is correct. Important: If the CPU does not easily fit into the socket, do not force it.
Inserting a new Socket-478 CPU into the
PL-P4/N onboard CPU socket. Removing the original heatsink/fan and
CPU, then insert the PL-P4/N into the ZIF
Socket-423.
Locking the arm of the ZIF Socket down,
thus the PL-P4/N will seat firmly.
Inserting the supplied power cable to the
PL-P4/N power connector. Putting the Powerleap heatsink/fan on top
of the new PL-P4/N CPU. Hooking the clip of the PL-P4/N customized
heatsink/fan.
To install the PL-P4/N™ in a 423-pin Pentium™ 4 ZIF socket:
1. Unplug the computer and remove the computer cover.
2. Lift the arm of the computer’s ZIF socket and remove the original Socket 423 Pentium™ 4 CPU and its heatsink/fan.
3. Install the PL-P4/N™ into your computer’s ZIF socket. Lock the PL-P4/N™ into the ZIF socket by pressing the socket
arm down, then attach the supplied power cable to the PL-P4/N’s power connector. Note that you need to connect the
other end to the power connector of the main power-supply unit.
4. The photo shows using the Powerleap® customized HSF (heatsink/fan). If you want to use the original Socket-423
HSF, please refer to the “Appendix” (Using our screw tool to raise the height of the retention mechanism).
