What You Need to Know About the AMD Socket 7 Motherboard

The term Socket 7 refers to a set of electrical and physical specifications for an x86-type central processing unit on a computer motherboard. Processors that use X7 are manufactured by AMD (K5 (75 to 133 MHz), K6 (166 to 300 MHz)), as well as Intel (P5 Pentium, MMX), and others. Socket 7 uses a 19x19 pin (321-pin) SPGA ZIF socket or an extremely unusual 37x37 pin (296-pin) SPGA LIF socket.

What do the acronyms SPGA, ZIF, and LIF mean?

SPGA stands for staggered pin grid array. Also known as intersecting squares, this means that the metal pins on the circuit board are arranged in concentric squares, with each row of pins staggered with respect to the adjacent rows, much like the way you would lay floor tiles. ZIF stands for zero insertion force, meaning there is a slider that separates the sprung contacts so the socket can be inserted into the surrounding chip set without using force. An LIF (low insertion force) socket is one that inserts easily into place.

Which AMD products use the Socket 7 motherboard?

You will find the Socket 7 motherboard in the following AMD processors: Athlon (Slot A), Athlon (Socket A), Duron, Athlon MP, Mobile Athlon 4, Athlon XP, Mobile Athlon XP, Mobile Duron, Sempron, and Mobile Sempron. In terms of end products, it is mainly found in laptops and notebooks, and it is a good choice if you are building a retro gaming rig.

Which laptop uses an Athlon CPU with the Socket 7?

Mobile Athlon XP processors are used in the Fujitsu Siemens Amilo A. The Amilo A series of notebook computers is aimed at mobile computer users who are looking for high performance and reliability. The Amilo A features PowerNow! energy-saving technology. NEC uses the Athlon 4 mobile CPU in its notebook PCs, while Sony has been known to put the Duron in its 15.1-inch VAIO PCG-973L.

Can you use the Socket 7 on a desktop computer?

This is not a good idea for a number of reasons:

  • Notebook CPUs tend to be weaker than the ones used in desktop computers.
  • Provided you are even able to winkle the CPU out of the laptop without causing permanent damage to either it or the laptop, you are going to need a Socket P motherboard that has a PCIe x16. For the same price, you could get a desktop motherboard, more memory, and a faster CPU.
  • The cost of a desktop hard drive is more than offset by the cost of a mobile heatsink.
