Intel Pentium III microprocessor with MMX technology

PC 300 GL personal computer types 6563, 6564, and 6574 and PC 300 PL personal computer type 6565 come with an Intel Pentium III microprocessor. The microprocessor has an attached heat sink which plugs directly into a connector on the system board.

More information on this microprocessor is available at http://www.intel.com on the World Wide Web.

Features

The features of the Pentium III microprocessor are as follows:

•Optimization for 32-bit software

•Operation at a low voltage level

•Intel microprocessor serial number

•64-bit microprocessor data bus

•100-133 MHz front-side bus (FSB)

•Math coprocessor

•Internet Streaming SIMD extensions

•MMX technology, which boosts the processing of graphic, video, and audio data

L2 Cache

The Pentium III microprocessor provides up to 512 KB L2 cache. The L2 cache error corrected code (ECC) function is automatically enabled if ECC memory is installed. If nonparity memory is installed, the L2 cache is non-ECC.

Chip set control

The chip set design is the interface between the microprocessor and the following:

•Memory subsystem

•PCI bus

•IDE bus master connection

•High performance, PCI-to-ISA bridge

•USB ports

•SMBus

•Enhanced DMA controller

•Real-time clock (RTC)

System memory

The maximum amount of system memory the computer can physically accommodate is 1 GB total. The amount of system memory factory-preinstalled varies by model.
