What the Xeon E5-2697 v3 is
The Xeon E5-2697 v3 is a flagship retail Haswell-EP fourteen core for dual socket servers on LGA 2011-v3. Intel set fourteen cores and 28 threads at 2.6 GHz base with turbo to 3.6 GHz. Thirty five megabytes of Smart Cache cover very large tenants. Power is 145 W on 22 nm from September 2014. Retail distribution brings broad C612 board support for clouds that need top fourteen core speed.
Fourteen cores with wide turbo to 3.6 GHz serve both parallel guests and single thread steps. Base clocks hold all core work while bursts lift control tasks. Huge cache trims memory waits. ECC DDR4 guards data. No integrated graphics exist. Fabric and NVMe storage shape node throughput. Buyers pick the 2697 v3 where fourteen cores must stay fast without moving to eighteen core thermals.
DDR4 ECC over four channels feeds each socket with two QPI links between dual nodes. The mix is a server socket for flagship hosts with protection at 145 W.
Socket and motherboard compatibility
The E5-2697 v3 fits LGA 2011-v3 on C612 Grantley boards for single and dual socket use. Retail stepping validates across vendors. Check the matrix for the minimum BIOS. X99 desktop boards never suit this server flagship.
ECC RDIMMs over four channels carry memory. The Socket vs chipset: what decides whether a CPU works guide is desktop focused, so use server NUMA maps. Cooling is vendor 145 W heatsinks with strong rack airflow.
No larger fourteen core exists here. Density growth means sixteen and eighteen core E5 v3 on the same boards.
Memory, PCIe and cooling
DDR4 ECC quad channel per socket suits massive guests. Even populations protect NUMA fairness. Large RDIMMs reach high counts. Speed follows DIMM count per manual.
Forty PCIe lanes per socket feed fabric HBAs and NVMe. NUMA aware placement across QPI links matters at fourteen cores. Board manuals guide choices.
Vendor 145 W cooling sustains loads with cool inlets. No retail cooler exists. Turbo to 3.6 GHz needs per core headroom.
Upgrade paths
Within the socket the Intel Xeon E5-2695 v3 with fourteen OEM threads suits vendor systems. The Intel Xeon E5-2698 v3 with sixteen retail threads is a higher density step. Both share C612 mounting.
Newer sockets replace Grantley. The E5-2697 v3 covers flagship fourteen core hosts where retail speed at 145 W is wanted.
