2.3 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
•
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 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.
2.3.1 Installing the CPU
To install a CPU:
1. Locate the CPU socket on the motherboard.
