Socket A / socket 462


Socket A (also known as Socket 462) is the CPU socket used for AMD processors ranging from the Athlon Thunderbird to the Athlon XP/MP 3200+, and AMD budget processors including the Duron and Sempron. Socket A also supports the recent AMD Geode NX embedded processors (derived from the Mobile Athlon XP). The socket is a zero insertion force pin grid array type with 453 pins (nine pins are blocked in the socket to prevent accidental insertion of Socket 370 CPUs, hence the number 462). The front side bus frequencies supported for the AMD Athlon XP and Sempron are 133 MHz, 166 MHz, and 200 MHz.
AMD recommends that the mass of a Socket A CPU cooler not exceed 300
grams (10.6 ounces). Heavier coolers may result in damage to the die when the system is not properly handled.
Socket A has been discontinued in favor of
Socket 754, Socket 939, and recently Socket AM2, except for its use with Geode NX processors. However, microprocessors and motherboards from many vendors are still available
