2-4 Chapter 2: Hardware information
2.4 Central Processing Unit (CPU)
2.4.1 Overview
The motherboard comes with dual surface mount 604-pin Zero Insertion
Force (ZIF) sockets. The sockets are designed for the Intel
® Xeon™
Processor in the 603/604-pin package. The processor includes the Intel
NetBurst™ micro-architecture that features the hyper-pipelined
technology, rapid execution engine, 533MHz/400MHz system bus, and
execution trace cache. Together, these attributes improve system
performance by allowing higher core frequencies, faster execution of
integer instructions, and data transfer rate of up to 4.2GB/s.
Note in the illustration that the CPU has a gold triangular mark on one
corner. This mark indicates the processor Pin 1 that should match a
specific corner of the CPU socket.
Incorrect installation of the CPU into the socket may bend the pins and
severely damage the CPU!
The motherboard supports either one or two CPUs. If you are installing
only one CPU, you MUST install it in CPU socket 1.
