ASUS O.C. Profile The motherboard features the ASUS O.C. Profile that allows you to conveniently store or load multiple BIOS settings. The BIOS settings can be stored in the CMOS or a separate file, giving you the freedom to share and distribute your favorite settings. ASUS MyLogo2™ This feature allows you to convert your favorite photo into a 256-color boot logo for a more colorful and vivid image on your screen.
1.4 Before you proceed Take note of the following precautions before you install motherboard components or change any motherboard settings. • Unplug the power cord from the wall socket before touching any component. • Before handling components, use a grounded wrist strap or touch a safely grounded object or a metal object, such as the power supply case, to avoid damaging them due to static electricity. • Hold components by the edges to avoid touching the ICs on them.
1.5 Motherboard overview Before you install the motherboard, study the configuration of your chassis to ensure that the motherboard fits into it. Ensure that you unplug the power cord before installing or removing the motherboard. Failure to do so can cause you physical injury and damage motherboard components. 1.5.1 Placement direction 1.5.2 Screw holes When installing the motherboard, ensure that you place it into the chassis in the correct orientation.

1.6 Central Processing Unit (CPU) The motherboard comes with a surface mount LGA1156 socket designed for the Intel® Core™ i7 / Core™ i5 / Core™ i3 / Pentium® processors. Unplug all power cables 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.
1.6.2 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. CPU FAN PWM CPU FAN IN CPU FAN PWR GND CPU_FAN P7H55-M CPU fan connector Do not forget to connect the CPU fan connector! Hardware monitoring errors can occur if you fail to plug this connector. 1.6.3 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.
4. Carefully remove the heatsink and fan assembly from the motherboard. 5. Rotate each fastener clockwise to ensure correct orientation when reinstalling. 1.7 System memory 1.7.1 Overview DIMM_B2 DIMM_B1 DIMM_A2 DIMM_A1 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.
1.7.2 Memory configurations You may install 512MB, 1GB, 2GB, and 4GB unbuffered 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.
