What the Xeon LC5518 is
The Intel Xeon LC5518 is a quad core Jasper Forest storage processor from February 2010. It runs four Nehalem class cores at 1733 MHz base with Turbo Boost to 2133 MHz, with Hyper-Threading for eight threads. Cache is 8 MB on a 45 nm process. Power is rated at 48 W on LGA 1366.
The LC prefix marks low voltage with turbo headroom for storage bursts. Against the EC5539 it doubles cache at lower power with lower base clocks. Per-SKU details beyond the task list survive in few open sources, so this page stays close to the listed values.
There is no graphics on this die. I/O comes from the storage board chipset.
Socket and motherboard compatibility
The Xeon LC5518 fits LGA 1366 with 1366 lands. Storage boards with Jasper Forest firmware boot it directly.
The socket table carries no per-codename claim for Jasper Forest, so the page shows the neutral sentence. The Socket vs chipset: what decides whether a CPU works guide covers pairing rules.
Memory, PCIe and cooling
Memory is DDR3 ECC through the board design.
PCIe comes from the board chipset for storage controllers.
Cooling uses a server heatsink rated for 48 W on the 80 × 80 mm pattern.
Upgrade paths
On LGA 1366 the storage upgrade is a faster Jasper Forest such as the EC5549 class on the same board. Beyond the storage platform a move to Xeon 5600 series needs a standard server board.
