Differences between Socket 5 and Socket 7

Symptom(s):

  • Socket 5
  • Socket 7
  • Upgrade
  • Upgrading

Solution:
Socket 7 is a 321-pin ZIF (Zero Insertion Force) processor socket and is a superset of the previous 320-pin Socket 5. Socket 7 provides the option and capability to support both unified-plane processors and split-plane, dual voltage processors. Socket 7 requires that the CLK and PICCLK signals be driven at 3.3 volts.

All Intel® Pentium® processors that are compatible with Socket 5 are compatible with Socket 7, but Intel Pentium Processors with MMX™ technology are designed for Socket 7 and are not compatible with Socket 5.

The presence of a particular socket on a motherboard does not necessarily indicate that motherboard will support all speeds of a particular processor. Contact the system or motherboard manufacturer for information on which processor speeds are supported.

For more information on Socket 7, refer to Chapter 17 of the Intel® Pentium® Processor Family Developer's Manual, 1997.

This applies to:
Intel® Pentium® Processor
Intel® Pentium® Processor with MMX™ Technology
Mobile Intel® Pentium® Processors
