1-8 System Overview
Pentium III Processor
Depending on system configuration, each system includes one or two Pentium III
processors. Each Pentium III processor is packaged in a Single Edge Contact Cartridge
Version 2 (SECC2). The cartridge includes the processor core with an integrated 16 KB
primary (L1) cache, a secondary (L2) cache, and a back cover. The processor
implements the MMX
™
technology and the processor’s numeric coprocessor
significantly increases the speed of floating-point operations.
The processor external interface operates at a maximum of 133 MHz. The second-level
cache is located on the substrate of the processor cartridge. The cache includes burst
pipelined synchronous static RAM (BSRAM).
System Memory
The system board contains four 168-pin DIMM sockets. Memory is partitioned as four
banks of SDRAM registered DIMMs (PC133 compatible), each providing 72 bits of
noninterleaved memory (64-bit main memory plus ECC). Your system may include
from 64 MB to 4 GB of memory, using up to four DIMMs.
System memory begins at address 0 and is continuous (flat addressing) up to the
maximum amount of DRAM installed (exception: system memory is noncontiguous in
the ranges defined as memory holes using configuration registers). The system
supports both base (conventional) and extended memory.
