1.6 Central Processing Unit (CPU) The motherboard comes with an AM3 socket designed for AMD® Phenom™ II / Athlon™ II / Sempron™ 100 Series Processors. The CPU socket is not compatible with AMD® Opteron™ processors. Do not install an Opteron™ processor on this motherboard. 1.6.1 Installing the CPU To install a CPU: 1. Locate the CPU socket on the motherboard. 2. Press the lever sideways to unlock the socket, then lift it up to a 90°–100° angle.
5. When the CPU is in place, push down the socket lever to secure the CPU. The lever clicks on the side tab to indicate that it is locked. 6. Install a CPU heatsink and fan following the instructions that came with the heatsink package. You can also refer to section 1.6.2 Installing the heatsink and fan for instructions. 7. Connect the CPU fan cable to the CPU_FAN connector on the motherboard.
Your boxed CPU heatsink and fan assembly should come with installation instructions for the CPU, heatsink, and the retention mechanism. If the instructions in this section do not match the CPU documentation, follow the latter. 2. Attach one end of the retention bracket to the retention module base. 1 2 3 3. 4 5 Align the other end of the retention bracket to the retention module base. A clicking sound denotes that the retention bracket is in place.
1.7.2 Channel Sockets Channel A DIMM_A1 and DIMM_B1 Channel B DIMM_A2 and DIMM_B2 Memory configurations You may install 512MB, 1GB, 2GB and 4GB unbuffered ECC 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.

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.
1.8 Expansion slots In the future, you may need to install expansion cards. The following sub‑sections describe the slots and the expansion cards that they support. Unplug the power cord before adding or removing expansion cards. Failure to do so may cause you physical injury and damage motherboard components. 1.8.1 Installing an expansion card To install an expansion card: 1.
1.9 Jumper Clear RTC RAM (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.
1.10 Onboard switch Onboard switches allow 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. Core Unlocker switch This switch allows you to unlock the extra cores of your CPU. • The UNCLOCKER_LED near the Core Unlocker switch lights when the switch setting is turned to Enable. Refer to section 1.11 Onboard LEDs for the exact location of the UNLOCKER_LED. • You may also press <4> during the Power-On-Self-Test (POST) to activate the Core Unlocker function. • The system will use the last setting you have made.
2. Core Unlocker LED The Core Unlocker LED lights when the Core Unclocker switch is turned to Enable.

Status Left LED Right LED OFF OFF OFF 10 Mbps connection Green (blinking during data activity) OFF 100 Mbps connection OFF Green (blinking during data activity) 1 Gbps connection OFF Green (blinking during data activity) Left LED Right LED LAN port 3.
Refer to the audio configuration table below for the function of the audio ports in 2, 4, 6, or 8-channel configuration.
2. ATX power connectors (24-pin EATXPWR, 4-pin ATX12V) These connectors are for an ATX power supply. The plugs from the power supply are designed to fit these connectors in only one orientation. Find the proper orientation and push down firmly until the connectors completely fit. • For a fully configured system, we recommend that you use a power supply unit (PSU) that complies with ATX 12 V Specification 2.0 (or later version) and provides a minimum power of 600 W.
3. AMD® SB850 Serial ATA Serial ATA 6.0 Gb/s connectors (7-pin SATA 1-6) These connectors are for the Serial ATA 6.0 Gb/s signal cables for Serial ATA hard disk drives and optical disc drives. If you installed Serial ATA hard disk drives, you can create a RAID 0, RAID 1, RAID 5, or RAID 10 configuration through the onboard AMD® SB850 controller. • These connectors are set to IDE mode by default. In IDE mode, you can connect Serial ATA boot/data hard disk drives to these connectors.
4. CPU, Chassis and Power Fan connectors (4-pin CPU_FAN, 3-pin CHA_FAN1, 3-pin PWR_FAN) Connect the fan cables to the fan connectors on the motherboard, ensuring that the black wire of each cable matches the ground pin of the connector. Do not forget to connect the fan cables to the fan connectors. Insufficient air flow inside the system may damage the motherboard components. These are not jumpers! DO NOT place jumper caps on the fan connectors.
5. System panel connector (20-8 pin PANEL) This connector supports several chassis-mounted functions. • System power LED (2-pin PLED) This 2-pin connector is for the system power LED. Connect the chassis power LED cable to this connector. The system power LED lights up when you turn on the system power, and blinks when the system is in sleep mode. • Hard disk drive activity LED (2-pin IDE_LED) This 2-pin connector is for the HDD Activity LED. Connect the HDD Activity LED cable to this connector.
6. USB connectors (10-1 pin USB78, USB910, USB1112) 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. Doing so will damage the motherboard! The USB 2.0 module is purchased separately. 7.
8. Front panel audio connector (10-1 pin AAFP) This connector is for a chassis-mounted front panel audio I/O module that supports either High Definition Audio or AC`97 audio standard. Connect one end of the front panel audio I/O module cable to this connector. • We recommend that you connect a high-definition front panel audio module to this connector to avail of the motherboard high-definition audio capability.
