Installling the CPUInstallling the CPU

Installling the CPU

To install a CPU:

1. Locate the CPU socket on the motherboard.

1.6 Central Processing Unit (CPU)

The motherboard comes with a surface mount LGA775 socket designed for

the Intel

®

Pentium

®

4 processor in the 775-land package.

•

Your boxed Intel

®

Pentium

®

4 LGA775 processor package should

come with installation instructions for the CPU, fan and heatsink

assembly. If the instructions in this section do not match the CPU

documentation, follow the latter.

• Upon purchase of the motherboard, make sure that the PnP cap is

on the socket and the socket pins are not bent. Contact your

retailer immediately if the PnP cap is missing, or if you see any

damage to the PnP cap/socket pins/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 pins

resulting from incorrect CPU installation/removal, or misplacement/

loss/incorrect removal of the PnP cap.

Before installing the CPU, make sure that the socket box is facing

towards you and the load lever is on your left.

3. Lift the load lever in the direction

of the arrow to a 135º angle.

4. Lift the load plate with your

thumb and forefinger to a 100º

angle (A), then push the PnP cap

from the load plate window to

remove (B).

To prevent damage to the socket pins, do not remove the PnP cap

unless you are installing a CPU.

5. Position the CPU over the

socket, making sure that

the gold triangle is on

the bottom-left corner of

the socket. The socket

alignment key should fit

into the CPU notch.

2. Press the load lever with your thumb (A) and move it to the left (B)

until it is released from the retention tab.

OverviewOverview

Overview

The motherboard comes with four Double Data Rate 2 (DDR2) Dual Inline

Memory Modules (DIMM) sockets.

A DDR2 module has the same physical dimensions as a DDR DIMM but has a

240-pin footprint compared to the 184-pin DDR DIMM. DDR2 DIMMs are

notched differently to prevent installation on a DDR DIMM socket.

The figure illustrates the location of the DDR2 DIMM sockets:

1.7.21.7.2

1.7.2

Memory configurationsMemory configurations

Memory configurations

You may install 256 MB, 512 MB and 1 GB unbuffered non-ECC DDR2

DIMMs into the DIMM sockets.

• For dual-channel configuration, the total size of memory module(s)

installed per channel must be the same (DIMM_A1 + DIMM_A2 =

DIMM_B1 + DIMM_B2).

• Always install DIMMs with the same CAS latency. For optimum

compatibility, it is recommended that you obtain memory modules

from the same vendor. Refer to the DDR2 Qualified Vendors List on

the next page for details.

• Due to chipset resource allocation, the system may detect less than

4 GB system memory when you installed four 1 GB DDR2 memory

modules.

• This motherboard does not support memory modules made up of

128 Mb chips or double sided x16 memory modules.
