2.3.1. 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.
4. When the CPU is installed correctly push the lever back into place.
5.
Install a proper heat sink with cooling fan
for proper heat dissipation. Failing
to install a heat sink with cooling fan may cause overheating 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 bigger Heat Sink that is required for the Pentium 4 CPU.
2.3.2. Memory Modules
These mainboards all have three 184-pin DDR SDRAM slots. If registered DDR SDRAM mod-
ules 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 fre-
quency and therefore heats up very quickly. (A normal heat sink will not be ade-
quate 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 main-
board.
