Central Processing Unit (CPU)
2.4.1 Overview
The motherboard comes with a surface mount LGA775 socket supports
the Intel
®
Core™2 Extreme / Core™2 Duo / Pentium
®
D / Pentium
®
4 /
Celeron
®
D processors in the 775-land package.
• 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 make sure 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.
2.4.2 Installing CPU
To install a CPU:
1. Locate the CPU socket on the motherboard.
Before installing the CPU, make sure that the socket box is facing
towards you and the load lever is on your left.
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.
