What the Xeon X3460 is
The Intel Xeon X3460 is a quad core Lynnfield server processor from September 2009. It runs four Nehalem cores at 2.8 GHz base with Turbo Boost to 3.467 GHz, with Hyper-Threading for eight threads. Each core carries 256 KB of L2 cache with 8 MB of shared L3 cache. Power is rated at 95 W on a 45 nm process.
The X3460 matches the desktop i7-860 on clocks with ECC support for single socket servers. Benchmark comparisons track it near the i7-860 class. Against the X3450 it adds base and turbo speed.
Memory is DDR3-1333 ECC in two channels.
Socket and motherboard compatibility
The Xeon X3460 fits LGA 1156 with 1156 lands. Server boards with 3400 series firmware boot it directly.
The socket table covers Lynnfield natively. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules, and the Intel Xeon X3480 page shows the top Xeon 3400 quad.
Memory, PCIe and cooling
Memory is DDR3-1333 ECC UDIMMs in two channels up to 16 GB on server boards.
PCIe 2.0 x16 comes from the CPU package.
Cooling is a server tower rated for 95 W on the 75 × 75 mm pattern.
Upgrade paths
On LGA 1156 the server upgrade is the X3470 or X3480 on the same board. Beyond LGA 1156 a move to Sandy Bridge Xeon E3 needs a new board.
