What the Athlon 64 X2 5800+ is
The AMD Athlon 64 X2 5800+ is the fastest stock Brisbane dual core, a 3.0 GHz part from April 2008. It runs two K8 cores at 3.0 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 89 W on Socket AM2.
It exists because AMD crowned the efficient Brisbane line with a 3.0 GHz flagship, giving K8 buyers top dual-core speed without the 125 W heat of older Windsor flagships. The 5800+ runs a 15x multiplier at around 1.40 V.
Socket and motherboard compatibility
The 5800+ 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 should be rated for 89 W on the 48 x 96 mm mount, a step above the 65 W Brisbane parts, with Cool'n'Quiet trimming clocks and voltage at idle.
Upgrade paths
On Socket AM2 the 5800+ is the stock clock ceiling, so the moves are sideways to the AMD Athlon 64 X2 5600+ at 65 W or the AMD Athlon 64 X2 5400+ BE Black Edition for overclocking. Beyond AM2 a move to AM2+ or AM3 needs a new board for Phenom class parts.
