•
Install a chassis fan with at least a speed of 2400 rpm and 8 CFM
turnrate when using a dual-core CPU to ensure system stability.
Overheating can permanently damage the system and/or CPU.
• Install an additional chassis fan to ensure better air flow when
overclocking.
• 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.
