What the Xeon E5-2667 is

Intel Xeon E5-2667 is a six core Sandy Bridge-EP server processor that Intel released in March 2012 for frequency sensitive dual socket servers. It runs at 2.9 GHz base with turbo to 3.5 GHz, with 15 MB cache and Hyper-Threading for 12 threads. Power is rated at 130 W on a 32 nm process. Very high clocks with six cores suit per thread licensed databases and latency sensitive tiers.

No integrated graphics are present. Memory spans DDR3-800 to 1600 over four channels with ECC, and the chip gives 40 PCIe 3.0 lanes plus two 8.0 GT/s QPI links. Twelve fast threads keep response direct where licenses cap sockets.

Boards pair it with registered DIMMs and fast storage in 1U and 2U chassis. All core work near 2.9 GHz behaves like a fast workstation with server I/O. The LGA, PGA and BGA: CPU package types explained guide contrasts this large socketed server part with soldered designs.

Socket and motherboard compatibility

The Xeon E5-2667 fits LGA 2011 in FCLGA2011 form. Dual socket Romley boards with the C600 series controller carry it. The vendor CPU list must include the exact E5-2667 string with Sandy Bridge-EP microcode.

At 130 W full size server heatsinks with directed airflow apply. The Socket vs chipset: what decides whether a CPU works guide covers server pairing.

Memory, PCIe and cooling

Memory support is DDR3 at 800, 1066, 1333 or 1600 MT/s, four channels, with ECC and registered DIMMs. Four populated channels per socket feed twelve threads.

PCI Express is 40 lanes of PCIe 3.0 per socket. Two QPI links at 8.0 GT/s join pairs. NUMA placement matters on dual boards.

Cooling is vendor qualified for 130 W. No retail mount exists.

Upgrade paths

Within LGA 2011 the Xeon E5-2667 can move to eight core Sandy Bridge-EP or Ivy Bridge-EP parts on the same board, trading clocks for threads. Memory and storage carry over. A v2 comparison is Intel Xeon E5-2667 v2 on the same socket.

A platform move means a DDR4 generation. Keep the node for licensed per core duty where fast Sandy cores still matter.

Frequently asked questions

What socket does the Intel Xeon E5-2667 use?

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

Does the Xeon E5-2667 have Hyper-Threading?

Yes. Six cores give 12 threads with turbo to 3.5 GHz.

What memory does the Xeon E5-2667 use?

DDR3 at 800, 1066, 1333 or 1600 MT/s, four channels, with ECC and registered DIMMs.

Is the Xeon E5-2667 for dual socket boards?

Yes. The 2600 numbering allows two sockets.
