Intel Xeon E5-2650 v3 socket: LGA 2011-v3

What the Xeon E5-2650 v3 is

The Xeon E5-2650 v3 is a mainstream Haswell-EP ten core for dual socket clouds on LGA 2011-v3. Intel set ten cores and 20 threads at 2.3 GHz base with turbo to 3.0 GHz. Twenty five megabytes of Smart Cache serve virtual guests. Power is 105 W on 22 nm from September 2014. Retail distribution brings broad C612 board support for private virtualization.

Ten cores consolidate guests per socket at modest power. Base clocks hold all core work while turbo covers control tasks. Large cache trims memory waits. ECC DDR4 guards data. No integrated graphics exist. Fabric and storage shape node throughput. Buyers pick the 2650 v3 where ten threads per socket meet the brief without reaching for 135 W flagships.

DDR4 ECC over four channels feeds each socket with two QPI links between dual nodes. The mix is a server socket for mainstream clouds with protection at 105 W.

Socket and motherboard compatibility

The E5-2650 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 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 NUMA maps. Cooling is vendor 105 W heatsinks with rack airflow.

A twelve core on the same socket adds threads where density grows. Confirm power ceilings before moving upward.

Memory, PCIe and cooling

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

Forty PCIe lanes per socket feed NICs, HBAs and NVMe. NUMA aware placement across QPI links matters at ten cores. Board manuals guide choices.

Vendor 105 W cooling sustains loads with front to back air. No retail cooler exists. Inlet temperature decides turbo residency.

Upgrade paths

On the same socket the Intel Xeon E5-2660 v3 with ten faster threads is a clock step on similar boards. The Intel Xeon E5-2640 v3 with eight cores trims density where threads matter less. Both share C612 mounting.

Newer server sockets replace Grantley. The E5-2650 v3 covers mainstream clouds where ten cores at 105 W are the target.
