Socket 939 Motherboard

The history of the motherboard is filled with various socket designs. Some were short-lived and quickly forgotten, while others lasted for years and became well known to computer enthusiasts. One of the more famous sockets to appear in recent years is Socket 939, which was used for many AMD Athlon processors released between 2004 and 2006. Even today, there are many computers available that have a Socket 939 motherboard with one of these processors installed. They sell for bargain basement prices on auction websites, but they are more than capable of running everything from word processors to video games.

A motherboard is a large circuit board that holds most of the essential parts of a computer. It is usually located inside the computer case that sits next to the monitor, but it may also be inside the monitor itself when there is no case. A typical motherboard used in a personal computer has one processor socket and several slots for the memory sticks. There are also slots for the video graphics card and other expansion cards, and sockets for the data cables from the various drives. Motherboards are group according to the type of processor socket they have, so a Socket 939 motherboard can be used with any Socket 939 processor.

Socket 939 gets its name because it has 939 holes arranged in a grid pattern on its surface. It belongs to a class of sockets called PGA-ZIF, which stands for pin grid array (PGA) and zero insertion force (ZIF). The pins on the base of a Socket 939 processor fit into the holes and are locked in place with spring contacts, which all move at the same time when the small lever on the side is lowered. This mechanism avoids the need to press down hard to get the pins into the holes, reducing the risk of damaging the fragile processor. It also reduces the time it takes to install a processor onto a Socket 939 motherboard.

The introduction of Socket 939 finally brought to a close the long run of Socket 754, which was the first Athlon64 socket and was used for many AMD processors released between 2003 and 2006. There are many reasons why it needed to be replaced, including its lower bandwidth limit and lack of support for dual-channel memory. Socket 939 was itself succeeded by socket AM2, which was introduced in 2006. During the years that Socket 939 was the leading AMD socket, its closest equivalent on the Intel side was LGA775, which was used for many Intel processors released between 2004 and 2006.

Installing a processor onto a Socket 939 motherboard is a simple task but it needs to be done carefully. The processor is placed on top of the socket and gently moved around until all the pins find their holes. Four key pins are used to ensure that the processor is correctly installed. These are missing pins and holes that are arranged in a unique pattern. After heat transfer paste has been applied to the base of the cooling fan, it is placed on the processor and secured with a spring clip. Two tabs on the sides of the socket are used to hold the ends of the spring clip, keeping it contact with the processor to maximize heat transfer.

With so many different motherboards and sockets around today, it is all too easy to pick up the wrong one, especially at computer fairs where the boxes tend to go missing. They all look very similar at a distance, but there are a couple of ways to spot a Socket 939 motherboard. The most obvious way is to look on the top of the socket for the words “Socket 939″, but it can be very difficult to spot them if the motherboard has a processor and fan attached to it. The other way is to look for a model number and check it on the internet. The model number is usually printed in white ink somewhere on the front of the front of the board.
