Chapter 1 Product introduction Thank you for buying an ASUS® P7H55/USB3 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 1-2 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® 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.
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 by lifting the tab only. PnP cap Cap tab 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 preapplied 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. • According to Intel spec definition, DDR3-1600 is supported for one DIMM per channel only.

1.4.3 Installing a DIMM Ensure to unplug the power supply before adding or removing DIMMs or other system components. Failure to do so may cause severe damage to both the motherboard and the components. 1. Unlock a DIMM socket by pressing the retaining clips outward. 2. Align a DIMM on the socket such that the notch on the DIMM matches the DIMM slot key on the socket. DIMM notch 1 2 1 DIMM slot key Unlocked retaining clip A DIMM is keyed with a notch so that it fits in only one direction.
1.5 Expansion slot In the future, you may need to install expansion cards. The following sub‑sections describe the slot and the expansion cards that it supports. Unplug the power cord before adding or removing expansion cards. Failure to do so may cause you physical injury and damage motherboard components. 1.5.1 Installing an expansion card To install an expansion card: 1.
1.6 Jumpers Clear RTC RAM (3-pin CLRTC) This jumper allows you to clear the Real Time Clock (RTC) RAM in CMOS. You can clear the CMOS memory of date, time, and system setup parameters by erasing the CMOS RTC RAM data. The onboard button cell battery powers the RAM data in CMOS, which include system setup information such as system passwords. To erase the RTC RAM: 1. Turn OFF the computer and unplug the power cord. 2. Move the jumper cap from pins 1-2 (default) to pins 2-3.
1.7 Onboard switches Onboard switch allows you to fine-tune performance when working on a bare or opencase system. This is ideal for overclockers and gamers who continually change settings to enhance system performance. 1. MemOK! switch Installing DIMMs that are incompatible with the motherboard may cause system boot failure, and the DRAM_LED near the MemOK! switch lights continuously.
2. Turbo Key II switch This switch allows you to auto-tune your CPU to enhance the system performance. For ensuring the system performance, turn the switch setting to Enable when the system is powered off. • The LED near the Turbo Key II switch lights when the switch setting is turned to Enable. • If you clear the CMOS or load the BIOS setup defaults, the related overclocking items in the BIOS menu follow the current setting of the Turbo Key II switch.
