What the Xeon E5-2683 v3 is
The Xeon E5-2683 v3 is an OEM Haswell-EP fourteen core for vendor clouds on LGA 2011-v3. Intel set fourteen cores and 28 threads at 2.0 GHz base with turbo to 3.0 GHz. Thirty five megabytes of Smart Cache cover dense tenants. Power is 120 W on 22 nm from September 2014. OEM distribution ties support to vendor system matrices.
Fourteen cores pack virtual machines per socket for large deployments. Modest clocks hold power while turbo covers single thread bursts. Huge cache trims memory waits. ECC DDR4 guards data. No integrated graphics exist. Fabric and storage shape throughput alongside cores. Used buyers meet this SKU in vendor pulls.
DDR4 ECC over four channels feeds each socket with two QPI links between dual nodes. The mix is a server socket for clouds where fourteen OEM threads at 120 W are the density point.
Socket and motherboard compatibility
The E5-2683 v3 fits LGA 2011-v3 on vendor C612 Grantley systems. OEM stepping may fail on generic boards, so confirm the matrix first. Desktop X99 never takes this OEM 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 vendor rules. Cooling is vendor 120 W heatsinks with rack airflow.
Retail fourteen core E5 v3 offer wider support where OEM locks bind. Check microcode before cross vendor use.
Memory, PCIe and cooling
DDR4 ECC quad channel per socket suits dense guests. Even maps protect NUMA fairness. Large RDIMMs reach high counts. Speed steps per manual.
Forty PCIe lanes per socket feed NICs and NVMe for fabric. NUMA placement across QPI links matters at fourteen cores. Vendor manuals detail slots.
Vendor 120 W cooling sustains loads with cool inlets. No retail cooler exists. Turbo follows per core states.
Upgrade paths
On the same socket the Intel Xeon E5-2695 v3 with fourteen cores offers similar density on vendor systems. The Intel Xeon E5-2680 v3 with twelve cores is a retail step for broader boards. Both need platform checks.
Newer sockets replace Grantley. The E5-2683 v3 covers OEM clouds where fourteen cores at 120 W are specified.
