Intel Xeon E5-2699 v3 socket: LGA 2011-v3

What the Xeon E5-2699 v3 is

The Xeon E5-2699 v3 is the retail Haswell-EP flagship with eighteen cores for dense servers on LGA 2011-v3. Intel set eighteen cores and 36 threads at 2.3 GHz base with turbo to 3.6 GHz. Forty five megabytes of Smart Cache cover the largest guest counts. Power is 145 W on 22 nm from September 2014. Retail distribution brings broad C612 board support unlike OEM eighteen core parts.

Eighteen cores top the v3 line for consolidation per socket in private clouds. Low base clocks hold power while wide turbo to 3.6 GHz lifts single thread steps. Huge cache trims memory waits across dozens of tenants. ECC DDR4 guards data. No integrated graphics exist. Fabric and NVMe storage shape node throughput. Buyers pick the 2699 v3 where maximum retail threads per socket decide schedules.

DDR4 ECC over four channels feeds each socket with two QPI links between dual nodes. The mix is a server socket for operators who want the flagship retail density with protection at 145 W.

Socket and motherboard compatibility

The E5-2699 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 to large counts. The Socket vs chipset: what decides whether a CPU works guide is desktop focused, so follow server NUMA maps. Cooling is vendor 145 W heatsinks with strong rack airflow.

No larger core count exists on this socket. Density growth means newer server sockets with fresh boards and memory.

Memory, PCIe and cooling

DDR4 ECC quad channel per socket suits massive virtualization. Even populations protect NUMA fairness. Large RDIMMs reach high guest counts. Speed follows DIMM count per manual.

Forty PCIe lanes per socket feed fabric HBAs and NVMe for cloud storage. NUMA aware placement across QPI links matters at eighteen cores. Board manuals guide controller choices.

Vendor 145 W cooling handles sustained all core work with cool inlets. No retail cooler exists. Turbo to 3.6 GHz needs per core headroom and inlet air.

Upgrade paths

On the same socket the Intel Xeon E5-2698 v3 with sixteen cores is a slightly smaller retail flagship on similar boards. The Intel Xeon E5-2680 v3 with twelve cores trims density for lower power. Both share C612 mounting.

Newer sockets replace Grantley. The E5-2699 v3 covers flagship hosts where eighteen retail cores at 145 W are wanted.
