Chapter 2 Chapter 2: 2.1 Before you proceed Hardware information 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.
2.2 Motherboard overview 2.2.1 Motherboard layout Chapter 2 Refer to 2.7 Connectors for more information about rear panel connectors and internal connectors.
Layout contents Connectors/Jumpers/Slots Page 1. ATX power connectors (24-pin EATXPWR, 8-pin EATX12V) 2-33 2. LGA1156 CPU Socket 2-5 3. CPU, chassis, and power fan connectors (4-pin CPU_FAN, 4-pin CHA_FAN1, 3-pin PWR_FAN) 2-31 4. DDR3 DIMM slots 2-10 5. Intel H55 Serial ATA connectors (7-pin SATA 1-6) 2-29 6. IDE connector (40-1 pin PRI_EIDE) 2-28 7. System panel connector (20-8 pin PANEL) 2-34 8. Serial port connector (10-1 pin COM1) 2-30 9.
2.2.3 Placement direction When installing the motherboard, ensure that you place it into the chassis in the correct orientation. The edge with external ports goes to the rear part of the chassis as indicated in the image below. 2.2.4 Screw holes Place eight 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.
2.3 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. 2.3.1 • 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 Chapter 2 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. 7. Close the load plate (A), and then push down the load lever (B), ensuring that the front edge of the load plate slides under the retention lock (C). Chapter 2 The Thermal Interface Material is toxic and inedible. DO NOT eat it.
2.3.2 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.
Connect the CPU fan cable to the connector on the motherboard labeled CPU_FAN. Chapter 2 3. DO NOT forget to connect the CPU fan connector! Hardware monitoring errors can occur if you fail to plug this connector. 2.3.3 Uninstalling the CPU heatsink and fan To uninstall the CPU heatsink and fan: 1. 2. 3. 4. Disconnect the CPU fan cable from the connector on the motherboard. Rotate each fastener counterclockwise.
2.4 System memory 2.4.1 Overview The motherboard comes with four Double Data Rate 3 (DDR3) Dual In-line 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.
2.4.2 Memory configurations • 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 and DDR3-1600 are supported for one DIMM per channel only. • According to Intel CPU spec, DIMM voltage below 1.65V is recommended to protect the CPU.
