the Intel ® Core™2/Pentium ® D/Pentium ® 4/Pentium ® Extreme and Celeron ® D
processors.
• 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.
• Make sure that all power cables are unplugged before installing the CPU.
• If installing a dual-core CPU, connect the chassis fan cable to the
CHA_FAN1 connector to ensure system stability.
