AMD Athlon 64 3400+ socket: Socket 754

What the Athlon 64 3400+ is

The AMD Athlon 64 3400+ is a 2.4 GHz single-core desktop processor from 2006. It runs one K8 core at 2.4 GHz with no turbo, so 1 core gives 1 thread. Cache is 512 KB of L2 on a 90 nm process. Power is rated at 67 W on Socket 754.

The 3400+ topped the late Venice 754 line on the 800 MT/s HyperTransport link with a 12x multiplier. It exists because buyers wanted the fastest Venice single core on Socket 754 without moving to dual channel Socket 939.

Socket and motherboard compatibility

The 3400+ drops into Socket 754 boards with DDR memory and a BIOS that lists late Venice single cores. It pairs with mainstream chipsets contemporary with Venice. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Memory, PCIe and cooling

Memory is DDR in a single channel through the on-chip controller.

HyperTransport at 800 MT/s links the CPU to the chipset. PCIe or AGP slots hang off the chipset.

Cooling is any 67 W rated Socket 754 heatsink on the 90 mm two-hole mount, with CoolnQuiet trimming draw at idle.

Upgrade paths

On Socket 754 the upgrade stays within Venice single cores, as the 3400+ tops the common 512 KB line. The AMD Athlon 64 3000+ (1.35v) at 2 GHz drops to 51 W for a lower cost. Beyond Socket 754 a move to Socket 939 or AM2 needs a new board and memory.
