Intel Xeon E5-2663 v3 socket: LGA 2011-v3

What the Xeon E5-2663 v3 is

The Xeon E5-2663 v3 is an OEM Haswell-EP ten core without Hyper-Threading for vendor clouds on LGA 2011-v3. Intel set ten cores and ten threads at 2.8 GHz base with turbo to 3.5 GHz. Twenty five megabytes of Smart Cache serve parallel services. Power is 105 W on 22 nm from September 2014. Disabled Hyper-Threading keeps per core behavior fixed for licensed or latency sensitive vendor workloads.

Ten fast threads at high clocks suit services that scale by cores rather than threads. Base clocks near 3 GHz keep response direct while turbo covers bursts. Large cache trims memory trips across services. ECC DDR4 guards data through long runs. No integrated graphics exist. Vendor firmware gates this OEM stepping to specific systems, so generic boards may reject it. Used buyers meet it in system pulls.

DDR4 ECC over four channels feeds each socket with two QPI links between dual nodes. The mix is a server socket for vendor clouds where per core licenses or deterministic behavior outweigh thread doubling.

Socket and motherboard compatibility

The E5-2663 v3 fits LGA 2011-v3 on vendor C612 Grantley systems. OEM validation ties stepping to the vendor matrix, so cross vendor moves may fail. Confirm the exact system support before sourcing used parts. Desktop X99 never accepts this OEM server chip.

Memory is ECC RDIMMs over four channels. The Socket vs chipset: what decides whether a CPU works guide is desktop focused, so use vendor manuals. Cooling follows vendor 105 W heatsinks with rack airflow.

Retail ten core E5 v3 with Hyper-Threading suit broader boards where vendor locks bind. Check microcode before any swap.

Memory, PCIe and cooling

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

Forty PCIe 3.0 lanes per socket feed fabric and storage for scale out nodes. NUMA aware placement across QPI links matters at ten cores. Vendor slot maps guide HBA choices.

Vendor 105 W cooling handles sustained loads with cool inlets. No retail cooler exists. Turbo to 3.5 GHz tracks per core power states.

Upgrade paths

Within the socket retail ten core parts with 20 threads fit generic C612 boards where OEM locks block use. The Intel Xeon E5-2640 v3 with eight cores offers retail availability for mixed loads. Both need platform checks.

Newer sockets replace Grantley. The E5-2663 v3 covers OEM clouds where ten threads without Hyper-Threading are the design point.
