Socket 462 socket: CPUs, chipsets and cooler fit

Socket 462 is the AMD zero insertion force pin grid array socket that carried Athlon Thunderbird through Athlon XP and Sempron processors from June 2000. It holds 462 contacts for ceramic and organic pin grid array packages measuring 49.53 × 49.53 mm, with about nine pins blocked to stop accidental insertion of Socket 370 parts. AMD printed the name Socket 462 on the socket body, while manuals and boards commonly call the same interface Socket A. The socket uses the Alpha EV6 bus at 200 MT/s, 266 MT/s, 333 MT/s and 400 MT/s with voltages from 1.0 V to 2.05 V for 32-bit CPUs only.

Overview

The socket matters for this batch because Thoroughbred Sempron parts such as the 1500 MHz Sempron 2200+ with 256 KB of L2 cache at 62 W and the 1583 MHz Sempron 2300+ at 62 W from July 2004 use Socket 462 boards with DDR slots. Thorton Sempron parts reuse the same 1500 MHz and 1667 MHz ratings with different part numbers from July to August 2004. Barton Athlon XP parts such as the 1917 MHz 2600+ with 512 KB at 68.3 W from September 2003 and the 2083 MHz 2800+ at 68.3 W from February 2003 use the same socket with a 333 MT/s front side bus. Mobile Barton DTR parts such as the 1917 MHz Athlon XP 2600+ DTR at 55 W from November 2004 and the 2083 MHz 2800+ DTR at 55 W from December 2004 also fit Socket 462 desktop-replacement notebooks with DDR memory.

Memory is DDR through the board chipset. Official AMD chipsets include the AMD 750 with the AMD 751 northbridge for 200 MT/s operation with SDRAM and AGP 2x, and the AMD 760 with the AMD 761 northbridge for 266 MT/s operation with DDR SDRAM and AGP 4x. Third party chipsets from VIA and NVIDIA carried most boards, including nForce and nForce2 and the VIA K series, with stability dependent on board makers following the chipset maker guidelines. Cooling clips to the socket lug, with some boards adding four holes in a 35 mm by 65 mm rectangle for larger heatsinks. AMD warns that cooler mass above 300 grams and load above 133 N static on the die surface can crack the exposed die.

Who Socket 462 serves

Socket 462 fits budget DDR towers that pair a Thoroughbred, Thorton or Barton single core with a board that lists the exact model. A Sempron 2200+ at 1500 MHz suits office towers at 62 W with a 333 MT/s bus and a 9x multiplier at 1.60 V. An Athlon XP 2600+ at 1917 MHz with 512 KB suits faster Socket 462 builds at 68.3 W with an 11.5x multiplier at 1.65 V. A DTR mobile part such as the Athlon XP 2600+ DTR at 1917 MHz suits desktop-replacement notebooks at 55 W where battery life matters less than socket compatibility. Every installation needs the board maker CPU list because late Barton support depends on clock, timing, BIOS and voltage handling, even though pin compatibility runs through the lifetime of the socket.

Older Palomino boards with 266 MT/s limits need a BIOS and voltage check before fitting a 333 MT/s or 400 MT/s Barton part. Boards wired for 200 MT/s operation with SDRAM cannot carry later DDR parts at full speed.

Memory and cooling

Memory on Socket 462 is DDR through the board chipset in a single channel. Common boards carry two or three DIMM sockets for modules matched to the front side bus, from PC1600 on early 200 MT/s boards to PC3200 on 400 MT/s Barton boards. The CPU carries 64 KB of L1 instruction and 64 KB of L1 data cache plus 256 KB or 512 KB of L2, with no on-chip memory controller. Expansion hangs off the board chipset because these CPUs provide no PCIe lanes. AGP 4x serves graphics on AMD 760 and later third party boards, with PCI slots for other cards. Cooling uses the socket lug clip centered on the die with a 46 mm by 46 mm minimum flat surface. Paste or pad application, room temperature and case airflow decide stability, since improper application on-hot room operation can overheat and crash exposed-die parts.

Frequently asked questions

Which processors fit Socket 462?

Thoroughbred Athlon XP and Sempron single cores such as the 1500 MHz Sempron 2200+ with 256 KB at 62 W from July 2004, Thorton Athlon XP parts such as the 1667 MHz 2000+ with 256 KB, and Barton parts such as the 1917 MHz Athlon XP 2600+ with 512 KB at 68.3 W and the 2133 MHz Athlon XP-M 2800+ DTR mobile parts covered here, plus Palomino Athlon XP parts from 1333 MHz to 1733 MHz from 2001 to 2002.

Is Socket 462 the same as Socket 754?

No. Socket 462 has 462 contacts with an EV6 front side bus and DDR memory through the board chipset, while Socket 754 has 754 contacts with an on-chip single channel DDR controller and an 800 MHz HyperTransport link. Forcing a chip can damage the board. The move from Socket 462 to Socket 754 needs a new board and DDR modules matched to the new chipset.

What memory does Socket 462 use?

DDR memory through the board chipset in a single channel. Boards commonly carry two or three DIMM sockets for PC1600 to PC3200 modules, with the exact speed set by the front side bus and the chipset. A move to DDR2 means a move to Socket AM2 with a new board.

How many PCIe lanes does Socket 462 provide?

No lanes come from these CPUs in the PCIe sense. A front side bus at 200 MT/s to 400 MT/s ties the CPU to the board chipset, while AGP 4x and PCI slots hang off the chipset for graphics and expansion. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
