This chapter provides step-by-step
instructions on how to install
components in the system.
Basic installation
* Only some of the T4 models have the
Time and IR LED display.
2-2 Chapter 2: Basic installation
2.1 Preparation
Before you proceed, ensure that you have all the components you plan to install in
the system.
Basic components to install
1. Central Processing Unit (CPU)
2. DDR2 Dual Inline Memory Module (DIMM)
3. Expansion card(s)
4. Hard disk drive
5. Optical drive
Tool
Philips (cross) screw driver
The motherboard comes with an onboard standby power LED. This LED lights
up to indicate that the system is ON, in sleep mode or in soft-off mode, and not
powered OFF. Unplug the power cable from the power outlet and ensure that the
standby power LED is OFF before installing any system component.
•
Use a grounded wrist strap or touch a safely grounded object or a metal
object, such as the power supply case, before handling components to
avoid damaging them due to static electricity.
•
Hold components by the edges to avoid touching the ICs on them.
•
Whenever you uninstall any component, place it on a grounded antistatic
pad or in the bag that came with the component.
2.2 Before you proceed
Take note of the following precautions before you install components into the
system.

2.4 Power supply unit
You need to turn over the power supply unit (PSU) section on the side before you
can install a central processing unit (CPU) and other system components.
To turn over the PSU:
1. Lay the system chassis on
its side on a at and stable
surface.
2. Locate and remove the two
screws that secures the PSU to
the chassis.
3. Lift the PSU in the direction of
the arrow to a 90º angle.
When removing the PSU, ensure to hold or support it rmly. The unit may
accidentally drop and damage other system components.
2-5ASUS T-P5G31
2.5 CPU installation
• Your boxed Intel® Pentium® 4 LGA775 processor package should
come with installation instructions for the CPU, heatsink, and the
retention mechanism. If the instructions in this section do not match
the CPU documentation, follow the latter.
•
Check your motherboard to ensure that the PnP cap is on the CPU socket
and the socket contacts are not bent. Contact your retailer immediately if
the PnP cap is missing, or if you see any damage to the PnP cap/socket
contacts/motherboard components. ASUS will shoulder the cost of repair
only if the damage is shipment/transit-related.
•
Keep the cap after installing the motherboard. ASUS will process Return
Merchandise Authorization (RMA) requests only if the motherboard comes
with the cap on the LGA775 socket.
• The product warranty does not cover damage to the socket contacts
resulting from incorrect CPU installation/removal, or misplacement/loss/
incorrect removal of the PnP cap.
2.5.1 Installing the CPU
Before installing the CPU, ensure that the socket box is facing towards you and
the load lever is on your left.
To install a CPU:
1. Locate the CPU socket on the motherboard.
To prevent damage to the
socket pins, do not remove
the PnP cap unless you are
installing a CPU.
2. Press the load lever with your thumb
(A), then move it to the left (B) until it
is released from the retention tab.

then push the PnP cap from the
load plate window to remove (4B).

2.5.2 Installing CPU fan and heatsink assembly
The Intel® Pentium® 4 LGA775 processor requires a specially designed heatsink
and fan assembly to ensure optimum thermal condition and performance.
• When you buy a boxed Intel® Pentium® 4 processor, the package
includes the CPU fan and heatsink assembly. If you buy a CPU separately,
ensure that you use only Intel®-certied multi-directional heatsink and fan.
• Your Intel
®
Pentium® 4 LGA775 heatsink and fan assembly comes in a
push-pin design and requires no tool to install.
If you purchased a separate CPU heatsink and fan assembly, ensure that the
Thermal Interface Material is properly applied to the CPU heatsink or CPU
before you install the heatsink and fan assembly.
To install the CPU heatsink and fan:
1. Place the heatsink on top of the
installed CPU, ensuring that the four
fasteners match the holes on the
motherboard.
2. Push down two fasteners at a time in
a diagonal sequence to secure the
heatsink and fan assembly in place.

2.6 Installing a DIMM
The system motherboard comes with two Double Data Rate 2 (DDR2) Dual Inline
Memory Module (DIMM) sockets.
The following gure illustrates the location of the sockets:
• Installing DDR2 DIMMS other than the recommended congurations
may cause memory sizing error or system boot failure. Use any of the
recommended congurations in the table on the next page.
• Install only
identical (the same type and size) DDR2 DIMMs in DIMM_A1
and DIMM_B1.
• Always install DIMMs with the same CAS latency. For optimum
compatibility, we recommend that you obtain memory modules from the
same vendor.
• Due to chipset resource allocation, the system may detect less than 4 GB
system memory when you installed two 2 GB DDR2 memory.
• This motherboard does not support memory modules made up of 128 Mb
chips or double-sided x16 memory modules.
2.6.1 Memorycongurations
You may install up to 4 GB system memory using 256 MB, 512 MB, 1 GB, and
2 GB DDR2 DIMMs.
