What the Xeon L5630 is
The Intel Xeon L5630 is a quad core Westmere-EP server processor from March 2010. It runs four Westmere cores at 2.133 GHz base with Turbo Boost to 2.4 GHz, with Hyper-Threading for eight threads. Cache is 12 MB of shared L3 on a 32 nm process. Power is rated at 40 W.
The L5630 pairs four threaded cores with a 40 W envelope for dense efficient nodes. IBM system options confirm 4C at 2.13 GHz with 12 MB and 40 W. Against the L5618 it adds base speed at the same 40 W.
Memory is DDR3 ECC triple channel per socket.
Socket and motherboard compatibility
The Xeon L5630 fits LGA 1366 with 1366 lands. Intel 5500 and 5520 chipset boards boot it with BIOS 45 or later.
The socket table covers Westmere-EP natively. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Memory, PCIe and cooling
Memory is DDR3 ECC triple channel per socket.
QPI links scale to dual socket nodes, with PCIe Gen 2 from the chipset.
Cooling uses server heatsinks rated for 40 W.
Upgrade paths
On LGA 1366 the server upgrade is a 60 W six core such as the L5640 on the same board. Beyond LGA 1366 a move to Sandy Bridge E5 needs a new board.
