AMD Sempron 3800+ socket: Socket AM2

What the Sempron 3800+ is

The AMD Sempron 3800+ is a 2.2 GHz single-core desktop processor from October 2006. It runs one K8 core at 2.2 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 AM2.

The Manila 3800+ topped the standard Manila line on an 800 MT/s HyperTransport link with an 11x multiplier. It exists because buyers wanted the fastest Manila Sempron with the larger 256 KB cache at the standard 62 W.

Socket and motherboard compatibility

The 3800+ drops into Socket AM2 boards with DDR2 memory and a BIOS that lists late 2006 Manila Sempron parts. It pairs with budget AM2 chipsets contemporary with the launch. 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 through the on-chip controller.

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

Cooling is any 62 W rated AM2 heatsink on the 48 × 96 mm mount, with CoolnQuiet trimming draw at idle.

Upgrade paths

On Socket AM2 the upgrade is an Athlon 64 single core such as Orleans at 2.2 GHz with 512 KB, or the AMD Sempron 3500+ at 2 GHz for a lower cost Sempron. Beyond AM2 a move to AM2+ or AM3 needs a new board for Phenom class parts.
