1.5 Microprocessor
The motherboard operates with 2.1 V to 3.5 V Pentium Pro processors. The onboard voltage
regulator is automatically programmed and controlled by the VID pins of the processor to provide
the required voltage. The motherboard supports Pentium Pro processors that run internally from
150 MHz up to 200 MHz.
The motherboard supports Pentium Pro processors with either 256 KB or 512 KB of second-level
cache.
The processor maintains full backward compatibility with the 8086, 80286, Intel386
TM
, Intel486
TM
,
and Pentium processors. Its numeric coprocessor maintains backward compatibility with math
coprocessors and that comply with ANSI/IEEE standard 754-1985.
1.5.1 Microprocessor Heatsink and Clips
CAUTION
Do not use the older style of bail-wire clips for securing the heat sink assembly. These clips have
been known to damage the motherboard when installed or removed incorrectly.
An approved Pentium Pro processor heat sink is necessary for proper thermal dissipation. The
processor/heat sink assembly must be securely fastened to the ZIF socket by two clips. These clips
fit over the heat sink assembly and attach to tabs on the socket.
1.5.2 Microprocessor Upgrade
The motherboard has a Socket 8 processor socket. Socket 8 is a 387-pin modified staggered pin
grid array (SPGA) ZIF socket with a voltage regulator for the processor core. The socket supports
upgrades to future Pentium Pro OverDrive
®
processors.
