What the Xeon X5460 is
The Intel Xeon X5460 is a 3.167 GHz performance server quad core from November 2007. It runs four Core cores at 3.167 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 120 W on Socket 771.
The X5460 led the 1333 MT/s performance line with a 9.5x multiplier at about 1172 dollars launch price. It exists because compute servers wanted clocks past 3 GHz with the full 12 MB cache where the chassis cools 120 W.
Socket and motherboard compatibility
The X5460 fits dual-socket Socket 771 server boards with a BIOS that lists performance Harpertown quads. It suits performance racks qualified for 120 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 1333 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 120 W envelope in performance chassis with directed airflow.
Upgrade paths
On Socket 771 the upgrade is the Intel Xeon X5470 at 3.333 GHz where listed at 120 W, or the Intel Xeon E5450 at 3 GHz for the same cache at 80 W. Beyond Socket 771 a move to a newer Xeon platform needs new boards and memory.
