What the Xeon L7545 is

The Intel Xeon L7545 is a six core Nehalem-EX part from March 2010. It runs six Beckton cores at 1.866 GHz base with Turbo Boost to 2.533 GHz, with Hyper-Threading for twelve threads. Cache is 18 MB of shared L3 on a 45 nm process. Power is rated at 95 W.

The L prefix marks low voltage with turbo headroom for efficient virtualization hosts. Against the 105 W E7540 it matches cache with lower power and similar turbo.

Memory is DDR3 ECC in four channels per socket.

Socket and motherboard compatibility

The Xeon L7545 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 an eight core such as the X7550 on the same board. Beyond LGA 1567 a move to Sandy Bridge E7 needs a new platform.

Frequently asked questions
