1.6 Central Processing Unit (CPU) This motherboard comes with an AM3+ socket designed for FX™ / Phenom™ II / Athlon™ II / Sempron™ 100 series processors. The AM3+ socket has a different pinout from the AM2+/AM2 socket. Ensure that you use a CPU designed for the AM3+ socket. The CPU fits in only one correct orientation. DO NOT force the CPU into the socket to prevent bending the pins and damaging the CPU! 1.6.1 Installing the CPU To install a CPU: 1. Locate the CPU socket on the motherboard.
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 comes with the heatsink package. You can also refer to section 1.6.2 Installing heatsink and fan for instructions. 7. Connect the CPU fan cable to the CPU_FAN connector on the motherboard.
1.6.2 Installing the heatsink and fan Ensure that you use only AMD-certified heatsink and fan assembly. To install the CPU heatsink and fan: 1. Place the heatsink on top of the installed CPU, ensuring that the heatsink fits properly on the retention module base. • The retention module base is already installed on the motherboard upon purchase. • You do not have to remove the retention module base when installing the CPU or installing other motherboard components.
3. Align the other end of the retention bracket to the retention module base. A clicking sound denotes that the retention bracket is in place. Ensure that the fan and heatsink assembly perfectly fits the retention mechanism module base, otherwise you cannot snap the retention bracket in place. 4. Push down the retention bracket lock on the retention mechanism to secure the heatsink and fan to the module base. 5.
1.7.2 Memory configurations You may install 1GB, 2GB, 4GB and 8GB 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. • Always install DIMMs with the same CAS latency.
