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
