What the Xeon E7520 is
The Intel Xeon E7520 is a quad core Nehalem-EX part from March 2010. It runs four Beckton cores at 1866 MHz with Hyper-Threading for eight threads and no turbo range listed. Cache is 18 MB of shared L3 on a 45 nm process. Power is rated at 95 W on LGA 1567.
The E7520 covers entry multiprocessor nodes where four cores with large cache suffice. Against the E6510 it adds cache at lower power. QPI links scale to eight sockets on Boxboro boards.
Memory is DDR3 ECC in four channels per socket.
Socket and motherboard compatibility
The Xeon E7520 fits LGA 1567 with 1567 lands. Boxboro 7500 boards boot it natively.

Memory, PCIe and cooling
Memory is DDR3 ECC in four channels per socket.
QPI links scale to eight sockets, with PCIe Gen 2 from the chipset.
Cooling uses server heatsinks rated for 95 W.
Upgrade paths
On LGA 1567 the upgrade is a six core such as the E7540 on the same board. Beyond LGA 1567 a move to Sandy Bridge E7 needs a new platform.
