What the Xeon E5-4667 v3 is
The Xeon E5-4667 v3 is a dense 16 core Haswell-EP part on LGA 2011-v3 for 4S virtualization. Intel set 16 cores and 32 threads at 2.0 GHz base with turbo to 2.9 GHz. Forty megabytes of Smart Cache feed many guests. Power is 135 W on 22 nm from the second quarter of 2015.
Sixteen cores maximize threads per socket for consolidation. Lower base clocks trade latency for density. Two QPI links at 9.6 GT/s connect four sockets with NUMA effects. Hyper-Threading doubles threads for oversubscribed hosts.
No integrated graphics exist. DDR4 ECC over four channels to 768 GB per socket feeds dense VMs. Buyers pick the 4667 v3 where thread count per rack outweighs per core speed.
Socket and motherboard compatibility
The 4667 v3 fits LGA 2011-v3 on C612 4S boards with E5-4600 v3 firmware. HEDT firmware lacks 4S support. Check vendor lists for the 16 core stepping before ordering spares.
Registered ECC DIMMs are mandatory. The Socket vs chipset: what decides whether a CPU works guide covers concepts, vendor manuals decide maps. LGA 2011 without v3 never boots.
Memory, PCIe and cooling
DDR4 ECC over four channels to 768 GB per socket with 2133 MHz support suits dense hosts. Full populations feed 32 threads. Balance memory per socket for NUMA fairness.
PCIe 3.0 with 40 lanes per socket serves networking and storage. Dense nodes need fabric bandwidth. VM placement should respect NUMA boundaries.
Cooling uses 135 W server heatsinks with strong airflow. Sixteen cores run hot under all core loads. Data center cooling decides sustained base.
Upgrade paths
On the same socket the Intel Xeon E5-4660 v3 at 14 cores saves power nearby, while the Intel Xeon E5-4669 v3 lifts to 18 cores for top density. All share LGA 2011-v3 where listed.
A v4 refresh needs new firmware. The 4667 v3 holds 16 core density in Haswell-EP 4S.
