Hardware Installation
The AZZA P4X MAINBOARD SERIES
Page 14
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.
2.4. CPU, Memory and Expansion Slots
52 pins40 pins
Top View of a 184-pin DIMM Slot
Hardware Installation
The AZZA P4X MAINBOARD SERIES Page 15
Important: The DIMM’s can only be fitted into the slots in one orientation. Make
sure that the DIMM’s are in the correct orientation and the pins are correctly
aligned before you insert them.
2.4.3. PCI Slots
These boards come with six PCI slots. They are located on the left hand side of
the board. Both PCI and PCI expansion cards may require IRQ’s. This mainboard
complies with Plug and Play (PnP) specifications. Whenever a PnP compliant card
is added the system will automatically be configured and the IRQ’s will be as-
signed automatically.
When you are inserting your PCI card make sure that the pins are correctly
aligned. When the pins are properly aligned with the hole’s in the slot, push
down gently.
2.4.4. AGP (Accelerated Graphics Port) Slot
AGP is a dedicated bus slot. It operates at 66 MHz and transfers data at a rate
up to 1066 MB/s. This allows 3D applications to run more smoothly. The P4X2-A
mainboards each come with one AGP slot. This slot is able to support 1x, 2x and
4x AGP cards.
NOTE: “Out Of Memory” Error Message
If you have installed more than 512 MB of RAM and are running Microsoft Windows Millennium Edition, Win-
dows 98 Second Edition, Windows 98 or Windows 95 you may experience memory problems. Two symptoms
of these problems are beingunable to run anMS-DOS session while you are running Windowsor the computer
may stop respondingwhile Windows is starting.
Thereare three possible solutionsto thisproblem:
1) Reduce the amount of memory Vcache uses to 512 MB or less by altering the MaxFileCache setting in
the System.ini file.
2) Use the System Configuration Utility to reduce the amountof memoryWindows uses to 512MB or less.
3) Reduce the memory installed on your computer to 512 MB or less.
This problem can also occur if youare using an Advanced Graphic Port (AGP)video adapter.
