AMD Sempron 2500+ socket: Socket 754

What the Sempron 2500+ is

The AMD Sempron 2500+ is a 1.4 GHz single-core desktop processor from July 2005. It runs one K8 core at 1.4 GHz with no turbo, so 1 core gives 1 thread. Cache is 256 KB of L2 on a 90 nm process. Power is rated at 62 W on Socket 754.

The Palermo 2500+ served budget Socket 754 towers on an 800 MT/s HyperTransport link with a 7x multiplier. It exists because buyers wanted the lowest cost entry to 90 nm Sempron desktops with 256 KB of cache.

Socket and motherboard compatibility

The 2500+ drops into Socket 754 boards with DDR memory and a BIOS that lists Palermo Sempron parts. It pairs with budget 754 chipsets contemporary with the July 2005 launch. 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 62 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 is the Sempron 2800+ at 1.6 GHz with 256 KB in the same 62 W class, or the AMD Sempron 3100+ at 1.8 GHz where the board lists low-power Sonora parts. Beyond Socket 754 a move to Socket AM2 needs a new board and DDR2 memory.
