AMD Athlon XP 2200+ socket: Socket 462

What the Athlon XP 2200+ is

The AMD Athlon XP 2200+ is a 1800 MHz single-core desktop processor from September 2003. It runs one K7 Thorton core at 1800 MHz with no turbo, so 1 core gives 1 thread. Cache is 256 KB of L2 on a 130 nm process. Power is rated at 62.8 W in a Socket 462 package with part numbers AXDC2200DLV3C and AXDC2200DUV3C. A duplicate cpu_list row repeats the same spec, so one page covers both entries.

The 2200+ Thorton uses a 266 MT/s front side bus with a 13.5x multiplier at 1.50 V or 1.60 V. It shares clocks with Thoroughbred 2200+ parts at 1800 MHz, yet the Model 10 stepping needs Thorton-aware BIOS tables. AMD placed it between the 1667 MHz 2000+ and the 2000 MHz 2400+ in the September 2003 Thorton stack. The chip supports MMX, SSE and Enhanced 3DNow.

Thorton naming confuses buyers because Thoroughbred, Thorton and Barton all sold a 2200+ at 1800 MHz with 256 KB on different steppings. The rating alone does not identify the die, so part numbers with AXDC mark Thorton against AXDA for Thoroughbred. Board lists that name Thorton explicitly are the safe match.

Socket and motherboard compatibility

The Athlon XP 2200+ Thorton fits Socket 462 DDR boards with a 266 MT/s bus and Thorton support. It needs Model 10 microcode, not just Thoroughbred firmware. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Value DDR towers are the natural match. Boards listing Thorton 2200+ accept the chip with a 62.8 W cooler. Older boards need a BIOS update for Model 10 operation.

Memory, PCIe and cooling

Memory is DDR through the board chipset in a single channel, matched to the 266 MT/s bus. The CPU has no controller.

A 266 MT/s bus ties the CPU to the chipset, while AGP and PCI hang off the chipset. No PCIe lanes originate on the die. Cooling uses the socket lug clip with a 62.8 W heatsink. Centered pressure and fresh paste protect the exposed die.

Upgrade paths

On Socket 462 the steps are the Athlon XP 2400+ Thorton at 2000 MHz and the 2600+ at 2133 MHz. Barton 2500+ parts at 1833 MHz offer 512 KB as a cache alternative. Beyond Socket 462 a move to Socket 754 needs a new board. The 2200+ lifts with the lever, so swaps need no solder work.
