Microprocessor
The motherboard supports a single Pentium 4 or Celeron processor. The processor’s
VID pins automatically program the voltage regulator on the motherboard to the
required processor voltage. In addition, the front side bus speed (400 & 533MHz) is
automatically selected. The motherboard currently supports processors that run
internally up to 2.8GHz + and have a 512KB second-level cache (128KB on Celeron)
running at full CPU Speed.
The processor implements MMX ™ technology and maintains full backward
compatibility with the 8086, 80286, Intel386 ™, Intel486 ™, Pentium, Pentium Pro &
Pentium II processors. The processor’s numeric coprocessor significantly increases
the speed of floating-point operations and complies with ANSI/IEEE standard 754-
1985.
Microprocessor Packaging
The Pentium 4 & Celeron processors come in a Micro-PGA package that connects to
the motherboard through a socket 478 connector. The package consists of:
•
Processor card including the processor core and the second-level cache
burst pipelined synchronous static RAM (BSRAM) and tag RAM.
•
Thermal plate.
•
Back cover.
Second Level Cache
The second-level cache is located on the die of the CPU itself. The cache includes burst
pipelined synchronous static RAM (BSRAM) and tag RAM. All supported onboard memory
can be cached.
