AMD Athlon XP 3200+ (400FSB) socket: Socket 462

What the Athlon XP 3200+ (400FSB) is

The AMD Athlon XP 3200+ (400FSB) is a 2200 MHz single-core desktop processor from May 2003. It runs one K7 Barton core at 2200 MHz with no turbo, so 1 core gives 1 thread. Cache is 512 KB of L2 on a 130 nm process. Power is rated at 76.8 W in a Socket 462 package with part number AXDA3200DKV4E on a 400 MT/s front side bus with an 11x multiplier at 1.65 V. The cpu_list 77 W value matches the table 76.8 W after rounding, and the table value is used here.

The 400FSB 3200+ tops the retail Barton line with the fastest bus and full 512 KB cache, above the 3000+ (400FSB) at 2100 MHz. AMD placed it in May 2003 as the flagship Socket A desktop before Socket 754 Athlon 64 parts took the high end. The chip supports MMX, Extended MMX, SSE, 3DNow and Enhanced 3DNow. A 333FSB 3200+ at 2333 MHz shares the rating on a slower bus with higher clocks as an HP-only part, so retail buyers received the 400FSB version covered here.

Flagship Socket A status made the part the final DDR upgrade for many towers. The 400 MT/s bus with 512 KB kept office and gaming tasks quick without a platform move. That is why the 3200+ (400FSB) remained a common used-market target for Socket 462 boards.

Socket and motherboard compatibility

The 3200+ (400FSB) fits Socket 462 DDR desktops with a 400 MT/s bus and Barton support. It needs DDR slots with 400 MT/s chipset paths. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Late retail DDR towers are the natural match. Boards listing the 400FSB 3200+ accept the chip with a 76.8 W cooler. Older 333 MT/s boards need a full chipset check for 400 MT/s operation.

Memory, PCIe and cooling

Memory is DDR through the board chipset, matched to the 400 MT/s bus for full speed. The CPU has no controller.

A 400 MT/s bus ties the CPU to the chipset, while AGP 8x and PCI hang off the chipset. No PCIe lanes originate on the die. Cooling uses the socket lug clip with a 76.8 W heatsink.

Upgrade paths

On Socket 462 the 3200+ (400FSB) tops retail Barton, so same socket upgrades stop here apart from OEM 333FSB bins. The 3000+ (400FSB) at 2100 MHz offers a slower clock where listed. Beyond Socket 462 a move to Socket 754 needs a new board. The chip lifts with the lever, so swaps need no solder work.
