What the Xeon E5630 is

The Intel Xeon E5630 is a quad core Westmere-EP server processor from March 2010. It runs four Westmere cores at 2.533 GHz base with Turbo Boost to 2.8 GHz, with Hyper-Threading for eight threads. Cache is 12 MB of shared L3 on a 32 nm process. Power is rated at 80 W.

The E5630 sits between the E5620 and E5640 at the same 80 W. IBM system options confirm 4C at 2.53 GHz with 12 MB. Against the E5640 it trails on turbo for bursty virtualization hosts.

Memory is DDR3 ECC triple channel per socket.

Socket and motherboard compatibility

The Xeon E5630 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 80 W.

Upgrade paths

On LGA 1366 the server upgrade is the E5640 or a six core on the same board. Beyond LGA 1366 a move to Sandy Bridge E5 needs a new board.
