What the Xeon E5606 is
Intel Xeon E5606 is a quad core Westmere-EP server processor that Intel released in February 2011 for single and dual socket boards. It runs at a fixed 2.13 GHz with no turbo and no Hyper-Threading, so 4 cores give 4 threads. Cache is 8 MB Intel Smart Cache. Power is 80 W on a 32 nm process.
The fixed clock suits entry nodes with predictable per-core speed. Dual socket boards hold 8 threads with this chip. The lack of turbo keeps power draw flat under load.
There is no integrated graphics on this die. Memory runs in three DDR3 channels at 1066 MT/s with ECC. System builders shipped it as a boxed and tray part.
Socket and motherboard compatibility
The Xeon E5606 fits LGA 1366 in FCLGA1366 form. Single and dual socket server boards with 5500 and 5520 chipsets carry it. The board BIOS must list the exact E5606 string.
QuickPath links run at 4.8 GT/s between sockets. A board that lists Xeon 56xx strings is the safe choice for dual socket builds.
Memory, PCIe and cooling
Memory support is DDR3-1066, three channels, with ECC for mission critical work. Three matched modules per socket give the rated bandwidth. Capacity follows the board design.
QPI links run at 2 by 4.8 GT/s. PCIe comes from the server chipset rather than the processor.
Cooling uses 80 W server heatsinks on the 80 by 80 mm pattern. Front to back airflow suits sustained loads.
Upgrade paths
On LGA 1366 the E5606 can move to the E5607 for higher fixed clocks on the same board. Memory and storage carry over where the board lists both strings. A threaded alternative on the same socket is the E5620 class with Hyper-Threading.
A platform move to LGA 2011 servers needs new boards and memory in fours. Keep the E5606 board for entry duty.
Frequently asked questions
What socket does the Intel Xeon E5606 use?
It uses LGA 1366 on single and dual socket server boards.
