P4X MAINBOARD SERIES

2.4.1. Installation of the CPU
To install your processor, please complete the following set of instructions
1. Locate a small dot marked on the top of the CPU. This mark indicates
Pin 1 of the CPU.
2. Locate Pin 1 for the Socket on the mainboard.
3.
There is a lever on the side of the socket. First push this lever sideways
and then lift it to a 90-degree angle.
4.
Insert the CPU into the Socket. Please make sure that Pin 1 for the CPU
is inserted into Pin 1 of the Socket.
5. When the CPU is installed correctly push the lever back into place.
6. Install a proper heat sink with cooling fan for proper heat dissipa-
tion. Failing to install a heat sink with cooling fan may cause overheat-
ing which will burnout your CPU and damage your mainboard. The heat
sink with cooling fan should be installed on the retention mechanism
that is provided. This retention mechanism is designed to hold the big-
ger Heat Sink that is required for the Pentium 4 CPU.
2.4.2. Memory Modules
These mainboards all have three 184-pin DDR SDRAM slots. If registered DDR
SDRAM modules are used then they can support a maximum of 3 GB DRAM. If
unbuffered DDR SDRAM modules are used they can support a maximum of 1.5
GB DRAM
The DDR SDRAM slots are located on the right hand side of the board. To install
the DIMM’s into these slots, make sure the white lever at each side of the slot
has been pulled down to an angle of approximately 45°. Make sure that the
DIMM is in the correct orientation. Place the DIMM on the slot and push down
firmly.The white levers will come back up and lock the module in place.
Heat Sink and Retention Mechanism
You must use an Intel approved Heat Sink. This CPU operates at a very
high frequency and therefore heats up very quickly. (A normal heat sink
will not be adequate to cool the CPU and the CPU will burn-out.) These
heat sinks are very heavy. A retention mechanism for the Heat Sink has
been provided with the mainboard.
