Chapter 1 Product introduction 1.1 Welcome! Thank you for buying an ASUS® P8H61-M EVO motherboard! The motherboard delivers a host of new features and latest technologies, making it another standout in the long line of ASUS quality motherboards! Before you start installing the motherboard, and hardware devices on it, check the items in your package with the list below. 1.2 Package contents Check your motherboard package for the following items.
Intel® H61 Express Chipset The Intel® H61 Express Chipset is the latest single-chipset design to support the new 1155 socket Intel® Core™ i7 / Core™ i5 / Core™ i3 2nd generation processors. It provides improved performance by utilizing serial point-to-point links, allowing increased bandwidth and stability.
100% All High-quality Conductive Polymer Capacitors This motherboard uses all high-quality conductive polymer capacitors for durability, improved lifespan, and enhanced thermal capacity. 1.3.2 Innovative ASUS features ASUS EFI BIOS (EZ Mode) ASUS brand new EFI BIOS offers a user-friendly interface that goes beyond traditional keyboard BIOS input to enable more flexible and convenient mouse controls.
Fan Xpert ASUS Fan Xpert intelligently allows you to adjust the CPU and chassis fan speeds according to different ambient temperatures caused by different climate conditions in different geographic regions and your PC’s loading. The built-in variety of useful profiles offer flexible controls of fan speed to achieve a quiet and cool environment. AI Suite II With its user-friendly interface, ASUS AI Suite II consolidates ASUS features into one simple to use software package.
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.
1.5.3 Motherboard layout 1 2 3 2 4 5 6 24.4cm(9.
1.6 Central Processing Unit (CPU) The motherboard comes with a surface mount LGA1155 socket designed for the Intel® 2nd Generation Core™ i7 / Core™ i5 / Core™ i3 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 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® LGA1155 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® LGA1155 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 P8H61-M EVO P8H61-M EVO 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_B1 DIMM_B2 DIMM_A1 DIMM_A2 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.
Recommended memory configurations One DIMM: We recommend you install one memory module in the blue slots (DIMM_A2 or DIMM_B2) to get better performance. Two DIMMs (dual-channel operation): Four DIMMs (dual-channel operation, single-sided DIMMs only): Due to Intel H61 regulation, when install four DIMMs to form a dual-channel operation, only DIMMs of single-sided are supported.
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. • Always install DIMMs with the same CAS latency.
