What the Athlon 64 4000+ is
The AMD Athlon 64 4000+ is a 2.6 GHz single core from February 2007. It runs one K8 core at 2.6 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 62 W on Socket AM2.
The Windsor stepping mirrors the Orleans F3 part at the same 2.6 GHz rating on a 1000 MHz HyperTransport link. The task list carries Windsor-stepping rows for the same single-core ratings, which these pages cover as their own SKUs. It supports DDR2 memory in two channels with AMD-V virtualization.
Socket and motherboard compatibility
The 4000+ drops into Socket AM2 boards with DDR2 memory and needs no special chipset or BIOS beyond standard K8 support. It pairs with 700 series DDR2 boards contemporary with AM2 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 62 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 4000+ is the 512 KB single-core ceiling on this stepping, so the moves are the AMD Athlon 64 4000+ (F3) at 2.6 GHz on the Orleans stepping, or the AMD Athlon 64 LE-1640 with 1 MB of cache. Beyond AM2 a move to AM2+ or AM3 needs a new board for Phenom class parts.
