2-4 Chapter 2: Hardware information
2.4.1 Overview
The motherboard comes with a surface mount 754-pin Zero Insertion
Force (ZIF) socket. The socket is designed for the new AMD Athlon™ 64
Processor in the 754-pin lidded ceramic micro PGA package. The AMD
Athlon™ 64 processor is a 64-bit desktop processor based on the
industry-standard x86 instruction set architecture that can run x86-based
32 and 64-bit applications. Integrated with the processor is a low-latency
high-bandwidth memory controller and a highly scalable HyperTransport™
technology-based system bus. Also, the processor includes Error
Correcting Code (ECC) protection for L1 and L2 cache data and DRAM
ECC protection with chipkill.
Additionally, the 128-bit-wide data paths of the AMD Athlon™ 64 processor
run applications faster than traditional processors with only 32 or 64-bit
wide data paths. Current 32-bit processors have a 4 gigabyte memory
addressing cap; the AMD Athlon™ 64 has a 40-bit physical and 48-bit
virtual addressing cap that enable systems to address up to 1 terabyte of
physical memory space and 256 terabytes of virtual memory.
Note in the illustration that the CPU
has a gold triangle in one corner. This
mark indicates the processor Pin A1
that should match a specific corner of
the CPU socket.
