What the Xeon X5482 is

The Intel Xeon X5482 is a 3.2 GHz top performance server quad core from November 2007. It runs four Core cores at 3.2 GHz with no turbo, so 4 cores give 4 threads. Cache is 12 MB of L2 as two 6 MB dies on a 45 nm process. Power is rated at 150 W on Socket 771.

The X5482 closed the Harpertown 5400 line on a 1600 MT/s bus with an 8x multiplier at about 1279 dollars launch price. It exists because flagship servers wanted the fastest 45 nm quad with the full 12 MB cache at the top 150 W envelope.

Socket and motherboard compatibility

The X5482 fits dual-socket Socket 771 server boards with a BIOS that lists 1600 MT/s flagship Harpertown quads. It suits flagship racks qualified for 150 W quads. Check the server maker CPU list for the exact board and stepping. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.

Memory, PCIe and cooling

Memory is DDR2 FB-DIMMs through the server board chipset.

A 1600 MT/s front side bus ties the CPU to the server chipset. PCIe slots hang off the chipset.

Cooling uses vendor qualified server heatsinks for the 150 W envelope in flagship chassis with directed airflow.

Upgrade paths

On Socket 771 the upgrade stays within flagship Harpertown, as the X5482 tops the 1600 MT/s line. The Intel Xeon X5472 at 3 GHz drops to 120 W with the same cache, or the Intel Xeon E5472 at 3 GHz drops to 80 W. Beyond Socket 771 a move to a newer Xeon platform needs new boards and memory.
