Asus P7H55-M SI - Manual (Page 13)

1.3 Central Processing Unit (CPU)
This motherboard comes with a surface mount LGA1156 socket designed for the
Intel ® Core™ i7 / Core™ i5 processors.
1.4 System memory
1.4.1 Overview
This motherboard comes with four Double Data Rate 3 (DDR3) Dual Inline Memory Module
(DIMM) sockets.
A DDR3 module has the same physical dimensions as a DDR3 DIMM but is notched
differently to prevent installation on a DDR3 DIMM socket. DDR3 modules are developed
for better performance with less power consumption. The figure illustrates the location of the
DDR3 DIMM sockets:

Ensure that all power cables are unplugged before installing the CPU.
• 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
LGA1156 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.
