System Overview

2.3.1 AMD Processor Support

The models covered in this guide are designed to support the following processor types:

■AMD Phenom X4 Quad-Core with HyperTransport Technology

■AMD Phenom X3 Triple-Core with HyperTransport Technology

■AMD Athlon X2 Dual-Core with HyperTransport Technology

■AMD Athlon 64 Single-Core with HyperTransport Technology

■AMD Sempron with HyperTransport Technology

All processors include an integrated DDR2 memory controller and support up to eight gigabytes of memory. AMD processors are backward-compatible with software written for earlier x86 microprocessors. The processor mounts in a zero-insertion-force (ZIF) AMD AM2+ socket.

CAUTION: These systems can support a processor rated up to 95 watts. Exceeding this limit can result in system damage and loss of data.

✎Installation of the processor heatsink is critical in these systems. Refer to the applicable Service Reference Guide for detailed removal and replacement procedures of the heatsink/fan assembly and the processor
