What the Xeon EC5509 is
The Intel Xeon EC5509 is a quad core Jasper Forest storage processor from February 2010. It runs four Nehalem class cores at 2.0 GHz with no turbo range listed. Cache is 4 MB on a 45 nm process. Power is rated at 85 W on LGA 1366.
The task list shows four cores with no thread count, so this page uses four threads without assuming Hyper-Threading, matching the EC3529 pattern in the same family. Against the EC5539 it trails on clocks and cache at the same power. Per-SKU details beyond the task list survive in few open sources.
There is no graphics on this die. I/O comes from the storage board chipset.
Socket and motherboard compatibility
The Xeon EC5509 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 85 W on the 80 × 80 mm pattern.
Upgrade paths
On LGA 1366 the storage upgrade is a turbo Jasper Forest such as the EC5549 on the same board. Beyond the storage platform a move to Xeon 5600 series needs a standard server board.
Frequently asked questions
What socket does the Xeon EC5509 use?
LGA 1366, the 1366-land package on storage boards with Jasper Forest firmware.
How many cores does the Xeon EC5509 have?
Four cores at 2.0 GHz with 4 MB of cache. The list shows no thread count, so no Hyper-Threading is assumed.
What memory works with the Xeon EC5509?
DDR3 ECC through the board design.
