1.4Before you proceed
Take note of the following precautions before you install motherboard components or change any motherboard settings.
•Unplug the power cord from the wall socket before touching any component.
•Use a grounded wrist strap or touch a safely grounded object or to 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.
•Before you install or remove any component, ensure that the ATX power supply is switched off or the power cord is detached from the power supply. Failure to do so may cause severe damage to the motherboard, peripherals, and/or components.

1.6Central Processing Unit (CPU)
The motherboard comes with a surface mount LGA775 socket designed for the Core™2 Duo/Pentium® D/Pentium® 4 and Celeron® D processors.
• Your boxed Intel® Core™2 Duo/Pentium® D/Pentium® 4 or Celeron® D
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
MerchandiseAuthorization (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.
1.6.1Installling the CPU
To install a CPU:
1.Locate the CPU socket on the motherboard.

1.6.2Installling the CPU heatsink and fan
The Intel® Core™2 Duo/Pentium® D/Pentium® 4 and Celeron® D processors require a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance.
•Install the motherboard to the chassis before you install the CPU fan and heatsink assembly
•When you buy a boxed Intel® Core™2 Duo/Pentium® D/Pentium® 4 or Celeron® D LGA775 processor, the package includes the CPU fan and heatsink assembly. If you buy a CPU separately, make sure that you use only Intel® certified multi directional heatsink and fan.
•Your I Intel® Core™2 Duo/Pentium® D/Pentium® 4 or Celeron® D 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, make sure that a 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, making sure that the four fasteners match the holes on the motherboard.

1.7System memory
1.7.1Overview
The motherboard comes with two Double Data Rate 2 (DDR2) Dual Inline Memory
Modules (DIMM) sockets.
ADDR2 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:

ChannelA |
DIMM_A1 and DIMM_A2 |
Channel B |
DIMM_B1 and DIMM_B2 |
|
|
1.7.2Memory configurations
You may install 256 MB, 512 MB, 1 GB and 2 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_B1).
•When installing two or three DDR2 DIMM modules for single-channel configuration, this motherboard only supports single-sided memory modules.
•When installing four DDR2 DIMM modules, install the single-sided memory modules.
•When installing four single-sided DDR2 DIMM modules, the transfer rate reduces to 533 MHz.
•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 next page for details.
