Hardware Installation
This section will assist you in quickly installing your system hardware. Wear a wrist ground strap
before handling components. Electrostatic discharge may damage your system components.
CPU Processor Installation
This mainboard supports Intel®Pentium®4 processors using a Socket 478. Before building your
system, we suggest you visit the Intel website and review the processor installation procedures.
http://www.intel.com
CPU Socket 478 Configuration Steps:
1. Locate the CPU socket on your mainboard and nudge the lever away from the socket. Then lift
the lever to a 90-degree angle.
2. On the socket, locate the corner that has the pin-1 receptor. This corner will be near to the end of
the lever. Match the dot on the CPU with the pin-1 receptor on the socket and lower the CPU onto the
socket. The bottom of the CPU should be flush with the face of the socket.
3. Lower the lever until it snaps back into position. This will lock down the CPU.
4. Smear thermal grease on top of the CPU. Lower the CPU fan onto the CPU and use the clasps on
the fan to attach it to the socket. Finally, extend the power cable from the fan and insert it onto the
CPUFAN adapter.
Pin1 Receptor
Dot
Attention: Before starting the system
Please check the installation completely before starting the
system. Verify that the heatsink is properly installed and make
sure the CPU fan is working. Overheating can damage the CPU
and other sensitive components.

PX865PE/ PX865P Series

FAN Headers
Three power headers are available for cooling fans, which play an important role in maintaining the
ambient temperature in your system.
Memory Installation
The series contains 4 memory slots which use 184 pin DDR SDRAM with a total memory capacity
of up to 4 GB. You can install unbuffered & non-ECC DDR DIMMs. It supports DDR266 when
installed with CPUs that have clock speeds of 100 MHz. It supports DDR266/333 when installed
with CPUs that have clock speeds of 133 MHz. And the PX865PE series supports also
DDR266/320/400 when installed with CPUs that have CPU clock speeds of 200 MHz.
The series provides Dual-Channel functionality for its DIMM slots. DIMM1 and DIMM2 share one
channel, while DIMM3 and DIMM4 share the other channel. Enabling dual channels can increase
your data access rates.
Attention
We strongly recommend that you use a CPU fan sink with you
r
CPU. You can attach the CPU fan sink to the CPUFAN Header.

RAM Module Installation:
1. Pull the white plastic tabs on each side of the slot away from the slot.
2. Match the notch on the button of the RAM module with the corresponding pattern in the DIMM
slot. This ensures that the module is inserted properly.
3. Lower the RAM module into the DIMM Slot and press firmly using both thumbs until the module
snaps into place.
4. Repeat steps 1 & 2 for the remaining RAM modules.
