CPU Socket 775
The motherboard comes with a surface mount LGA775 socket designed for
the Intel® Pentium® D, Pentium® 4 and Celeron® processor in the 775-land
package.
•
Upon purchase of the motherboard, make sure that the PnP cap is
on the 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 shoulders the repair cost 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.
2.3 .1 Ins ta ll ing t he CP U

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.
•
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, make
sure that you have properly applied Thermal Interface Material to
the CPU heatsink or CPU before you install the heatsink and fan
assembly.
•
If you buy a CPU separately, make sure that you use only
Intel®‑certied multi‑directional heatsink and fan.
•
Make sure that you have installed the motherboard to the chassis
before you install the CPU fan and heatsink 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.
Orient the heatsink and fan
assembly such that the CPU
fan cable is closest to the
CPU fan connector.
