What the Xeon E5-2609 is

Intel Xeon E5-2609 is a quad core Sandy Bridge-EP server processor that Intel released in March 2012 for entry dual socket servers. It runs at a fixed 2.4 GHz with no turbo and no Hyper-Threading, so 4 cores give 4 threads. Cache is 10 MB. Power is rated at 80 W on a 32 nm process. The 600 MHz step over the 2603 is the only change in kind.

No integrated graphics are present. Memory stays at DDR3-800 and 1066 over four channels with ECC. The chip gives 40 PCIe 3.0 lanes plus two 6.4 GT/s QPI links for socket pairs.

Higher fixed clocks suit single threaded infrastructure services that never use turbo. Boards pair it with registered DIMMs and basic RAID. The LGA, PGA and BGA: CPU package types explained guide contrasts this socketed server part with soldered designs.

Socket and motherboard compatibility

The Xeon E5-2609 fits LGA 2011 in FCLGA2011 form. Dual socket Romley boards with the C600 series controller carry it. The vendor list must show the exact E5-2609 string.

At 80 W standard server heatsinks apply. The Socket vs chipset: what decides whether a CPU works guide covers server pairing.

Memory, PCIe and cooling

Memory support is DDR3-800 and 1066, four channels, with ECC and registered DIMMs. Four populated channels feed four cores adequately.

PCI Express is 40 lanes of PCIe 3.0 per socket. The 6.4 GT/s QPI links join pairs. I/O stays near its socket on NUMA systems.

Cooling is vendor qualified for 80 W with chassis airflow. No retail mount exists.

Upgrade paths

Within LGA 2011 the Xeon E5-2609 can move to threaded or turbo equipped E5-2600 parts on the same board, adding Hyper-Threading first. Memory may step to faster DIMMs with the new SKU. A plain core comparison below is Intel Xeon E5-2603.

A platform move means a DDR4 generation. Keep the node for steady infrastructure duty.

Frequently asked questions

What socket does the Intel Xeon E5-2609 use?

It uses LGA 2011. C600 series dual socket boards carry it.

How is the Xeon E5-2609 different from the E5-2603?

Base is 2.4 GHz instead of 1.8 GHz. Both lack Hyper-Threading and turbo at 80 W.

What memory does the Xeon E5-2609 use?

DDR3-800 and 1066, four channels, with ECC and registered DIMMs.

Is the Xeon E5-2609 for dual socket boards?

Yes. The 2600 numbering allows two sockets.
