What the Xeon EC5539 is
The Intel Xeon EC5539 is a quad core Jasper Forest storage processor from February 2010. It runs four Nehalem class cores at 2.266 GHz with Hyper-Threading for eight threads. Cache is 4 MB on a 45 nm process. Power is rated at 65 W on LGA 1366.
The EC prefix marks the embedded storage line for control plane work at fixed clocks. Against the LC5518 it trades cache for clocks at higher power. 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 EC5539 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 65 W on the 80 × 80 mm pattern.
Upgrade paths
On LGA 1366 the storage upgrade is an 8 MB Jasper Forest such as the LC5518 on the same board. Beyond the storage platform a move to Xeon 5600 series needs a standard server board.
