1.3Central Processing Unit (CPU)

This motherboard comes with a surface mount LGA1155 socket designed for the Intel® Second Generation Core™i5/ Core™i3 processors.

•Upon purchase of the motherboard, ensure 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

LGA1155 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.

Ensure that all power cables are unplugged before installing the CPU.

1.4System memory

1.4.1Overview

This motherboard comes with four Double Data Rate 3 (DDR3) Dual Inline Memory Modules (DIMM) sockets. A DDR3 module has the same physical dimensions as a DDR2 DIMM but is notched differently to prevent installation on a DDR2 DIMM socket. DDR3 modules are developed for better performance with less power consumption. The figure illustrates the location of the DDR3 DIMM sockets:
