What the Athlon 64 X2 5400+ is
The AMD Athlon 64 X2 5400+ is a fast 2.8 GHz Brisbane dual core from January 2008. It runs two K8 cores at 2.8 GHz with no turbo, so 2 cores give 2 threads. Cache is 512 KB of L2 per core on a 65 nm process. Power is rated at 65 W on Socket AM2.
It exists because AMD pushed efficient Brisbane bins up the rating ladder, giving buyers near-flagship K8 dual-core speed without the 89 W-plus heat of older Windsor parts. The 5400+ runs a 14x multiplier on the standard 200 MHz reference clock.
Socket and motherboard compatibility
The 5400+ drops into Socket AM2 boards with DDR2 memory and needs no special chipset or BIOS beyond standard Brisbane support. It pairs with 700 series DDR2 boards contemporary with Brisbane parts. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Memory, PCIe and cooling
Memory is DDR2-667 and DDR2-800 in two channels.
HyperTransport at 1000 MHz links the CPU to the chipset. PCIe slots hang off the chipset.
Cooling is any 65 W rated heatsink on the 48 x 96 mm mount, with Cool'n'Quiet trimming clocks and voltage at idle.
Upgrade paths
On Socket AM2 the upgrade is the AMD Athlon 64 X2 5600+ at 2.9 GHz for a small step up, or the AMD Athlon 64 X2 5400+ BE Black Edition for overclocking headroom. Beyond AM2 a move to AM2+ or AM3 needs a new board for Phenom class parts.
