Intel Xeon E5-2667 v3 socket: LGA 2011-v3

What the Xeon E5-2667 v3 is

The Xeon E5-2667 v3 is a frequency tuned Haswell-EP eight core for fast dual socket servers on LGA 2011-v3. Intel set eight cores and 16 threads at 3.2 GHz base with turbo to 3.6 GHz. Twenty megabytes of Smart Cache serve latency sensitive guests. Power is 135 W on 22 nm from September 2014. Very high base clocks suit databases where response beats width.

A 3.2 GHz base is the fastest of the eight core v3 line and keeps all core work direct. Turbo to 3.6 GHz covers single thread bursts. Sixteen threads handle services beside guests with ECC memory. Large cache trims data waits. Fast fabric and NVMe matter more than core count here. It is a server socket for operators who pay for speed per core at 135 W.

No integrated graphics exist. DDR4 ECC over four channels feeds each socket with two QPI links between dual nodes. The mix suits transactional workloads where eight fast threads per socket decide hardware.

Socket and motherboard compatibility

The E5-2667 v3 fits LGA 2011-v3 on C612 Grantley boards for single and dual socket use. Check the vendor matrix for v3 stepping support. X99 desktop boards never suit this server chip.

ECC RDIMMs over four channels carry memory. The Socket vs chipset: what decides whether a CPU works guide is desktop focused, so use server manuals for maps. Cooling is vendor 135 W heatsinks with rack airflow.

A ten core on the same socket adds threads where parallel guests grow. Confirm thermal headroom before swapping frequency eight cores for wider parts.

Memory, PCIe and cooling

DDR4 ECC quad channel per socket suits fast guests. Balance DIMMs for bandwidth. Registered modules reach large counts. Speed follows population per manual.

Forty PCIe lanes per socket feed low latency NICs and NVMe for logs. NUMA placement across QPI links matters in dual nodes. Board manuals detail slot wiring.

Vendor 135 W cooling holds 3.2 GHz sustained loads with cool inlets. No retail cooler exists. Turbo residency tracks per core states.

Upgrade paths

On the same socket the Intel Xeon E5-2640 v3 with eight slower threads trims power on similar boards. The Intel Xeon E5-2630 v3 with eight cores is a lower clock retail step. Both share C612 mounting.

Newer server sockets replace Grantley. The E5-2667 v3 covers hosts where eight fast threads at 135 W are the design point.
