What the Xeon LC3528 is

The Intel Xeon LC3528 is a dual core Jasper Forest storage processor from February 2010. It runs two Nehalem class cores at 1733 MHz base with Turbo Boost to 1866 MHz, with Hyper-Threading for four threads. Cache is 4 MB on a 45 nm process. Power is rated at 35 W on LGA 1366.

The LC prefix marks low voltage in the embedded storage line at 35 W. Against the single core P1053 it doubles cores for storage control threads. 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 LC3528 fits LGA 1366 with 1366 lands. Storage boards with Jasper Forest firmware boot it directly. Retail X58 boards rarely list it.

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 35 W on the 80 × 80 mm pattern.

Upgrade paths

On LGA 1366 the storage upgrade is a quad 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.

Frequently asked questions
