Chapter 1 Product introduction Thank you for buying an ASUS® P7P55D LE motherboard! Before you start installing the motherboard, and hardware devices on it, check the items in your motherboard package. Refer to page ix for the list of accessories. If any of the items is damaged or missing, contact your retailer. 1.1 Before you proceed Take note of the following precautions before you install motherboard components or change any motherboard settings.
1.2 Motherboard overview 1.2.1 Motherboard layout Ensure that you install the motherboard into the chassis in the correct orientation. The edge with external ports goes to the rear part of the chassis. Place this side towards the rear of the chassis. Place six screws into the holes indicated by circles to secure the motherboard to the chassis. DO NOT overtighten the screws! Doing so can damage the motherboard. 1.2.2 Layout contents Connectors/Jumpers/Slots/LED Page 1.
1.3 Central Processing Unit (CPU) The motherboard comes with a surface mount LGA1156 socket designed for the Intel® Core™ i7 / Core™ i5 Processors. Ensure that all power cables are unplugged before installing the CPU. 1.3.1 • 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.
3. Lift the load lever in the direction of the arrow until the load plate is completely lifted. Load plate 4. Remove the PnP cap from the CPU socket. PnP cap 5. Position the CPU over the socket, ensuring that the gold triangle is on the bottom‑left corner of the socket, and then fit the socket alignment keys into the CPU notches. The CPU fits in only one correct orientation.
6. Apply some Thermal Interface Material to the exposed area of the CPU that the heatsink will be in contact with, ensuring that it is spread in an even thin layer. Some heatsinks come with pre-applied thermal paste. If so, skip this step. The Thermal Interface Material is toxic and inedible. DO NOT eat it. If it gets into your eyes or touches your skin, wash it off immediately, and seek professional medical help. 7.
1.3.2 Installing the CPU heatsink and fan The Intel® LGA1156 processor requires a specially designed heatsink and fan assembly to ensure optimum thermal condition and performance. • When you buy a boxed Intel® processor, the package includes the CPU fan and heatsink assembly. If you buy a CPU separately, ensure that you use only Intel®‑certified multi‑directional heatsink and fan. • Your Intel® LGA1156 heatsink and fan assembly comes in a push-pin design and requires no tool to install.
3. Connect the CPU fan cable to the connector on the motherboard labeled CPU_FAN. DO NOT forget to connect the CPU fan connector! Hardware monitoring errors can occur if you fail to plug this connector. 1.3.3 Uninstalling the CPU heatsink and fan To uninstall the CPU heatsink and fan: 1. Disconnect the CPU fan cable from the connector on the motherboard. 2. Rotate each fastener counterclockwise. 3.
1.4 System memory 1.4.1 Overview The 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.
1.4.2 Memory configurations You may install 1GB, 2GB and 4GB unbuffered and non‑ECC DDR3 DIMMs into the DIMM sockets. • You may install varying memory sizes in Channel A and Channel B. The system maps the total size of the lower-sized channel for the dual-channel configuration. Any excess memory from the higher-sized channel is then mapped for single-channel operation. • Due to Intel spec definition, X.M.P. DIMMs are supported for one DIMM per channel only.

6. USB connectors (10-1 pin USB910; USB1112; USB1314) These connectors are for USB 2.0 ports. Connect the USB module cable to any of these connectors, then install the module to a slot opening at the back of the system chassis. These USB connectors comply with USB 2.0 specification that supports up to 480 Mbps connection speed. Never connect a 1394 cable to the USB connectors.
8. Digital audio connector (4-1 pin SPDIF_OUT) This connector is for an additional Sony/Philips Digital Interface (S/PDIF) port(s). Connect the S/PDIF Out module cable to this connector, then install the module to a slot opening at the back of the system chassis. The S/PDIF module is purchased separately. 9. Optical drive audio connector (4-pin CD) This connector allows you to receive stereo audio input from sound sources such as a CD-ROM, TV tuner, or MPEG card.
10. JMicron® JMB361 IDE Connector (40-1 pin PRI_IDE [Blue]) The onboard IDE connector is for the Ultra DMA 133/100/66 signal cable. There are three connectors on each Ultra DMA 133/100/66 signal cable: blue, black, and gray. Connect the blue connector to the motherboard’s IDE connector, then select one of the following modes to configure your device.
1.9 Installing an operating system This motherboard supports Windows® XP/ 64-bit XP/ Vista™/ 64-bit Vista™/ 7/ 64-bit 7 operating systems (OS). Always install the latest OS version and corresponding updates to maximize the features of your hardware. 1.10 • Motherboard settings and hardware options vary.
