Processor Zif Socket The motherboard has a 423-pin zero insertion force (ZIF) socket that supports a single 423-pin Intel® Pentium® IV processor. The standard host bus speed of the motherboard is 100 megahertz (MHz). However, the Pentium IV processor uses a dual-clock, un-pipelined processing method that achieves host bus speeds up to 400 MHz.

Cache speeds: L1 and L2 cache both run at the full speed of the processor.

L1 cache features:

  • 8KB L1 data cache
  • Execution Trace Cache that stores up to 12-K decoded micro-ops in the order of program execution.
  • 4-way set associative
  • 64-byte cache lines
  • 256-bit data bus to the level 1 cache
  • Data clocked into and out of the cache every clock cycle

L2 Advanced Transfer Cache features:

  • Non-Blocking, full speed, on-die level 2 cache
  • 8-way set associativity
  • 256-bit data bus to the level 2 cache
  • Data clocked into and out of the cache every clock cycle

The heat sink does not connect to the ZIF socket, but attaches via pegs that attach to a heat sink stabilizer plate on the bottom of the motherboard.

The processor's voltage identification (VID) pins automatically program the motherboard's voltage regulator to the required processor voltage.
