processors.

• Ensure that all power cables are unplugged before installing the CPU.
• Connect the chassis fan cable to the CHA_FAN connector to ensure system stability.

• 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.
