AMD Athlon XP 3000+ (333FSB) socket: Socket 462

What the Athlon XP 3000+ (333FSB) is

The AMD Athlon XP 3000+ (333FSB) is a 2167 MHz single-core desktop processor from February 2003. It runs one K7 Barton core at 2167 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 74.3 W in a Socket 462 package with part number AXDA3000DKV4D on a 333 MT/s front side bus with a 13x multiplier at 1.65 V. The cpu_list 68 W value differs from the table 74.3 W, and the table value is used here.

The 333FSB version predates the 400FSB 3000+ at 2100 MHz from May 2003, trading a faster bus for 67 MHz more clocks at higher power. Both share the 3000+ rating with 512 KB, so bus and power separate the bins. AMD placed the 333FSB version in February 2003 with the 2800+ and 2500+ Barton parts. The chip supports MMX, Extended MMX, SSE, 3DNow and Enhanced 3DNow. Suffixes are part of the model here, giving each bus its own slug.

Higher power with a slower bus marks the older bin. The 74.3 W rating against 68.3 W on the 400FSB sibling reflects early stepping current at higher clocks. That is why the 333FSB version needs a stronger heatsink despite sharing the rating.

Socket and motherboard compatibility

The 3000+ (333FSB) fits Socket 462 DDR boards with a 333 MT/s bus and Barton support. It needs 333 MT/s chipset paths. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Mainstream DDR towers are the natural match. Boards listing the 333FSB 3000+ accept the chip with a 74.3 W cooler. The 400FSB sibling needs 400 MT/s paths instead.

Memory, PCIe and cooling

Memory is DDR through the board chipset, matched to the 333 MT/s bus. The CPU has no controller.

A 333 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 74.3 W heatsink.

Upgrade paths

On Socket 462 the steps are Barton 3200+ parts with the same cache on faster buses. The 400FSB 3000+ offers the same rating with a faster bus at lower power. Beyond Socket 462 a move to Socket 754 needs a new board. The chip lifts with the lever, so swaps need no solder work.
