Intel Xeon E5-2697 v3 14-Core Haswell Server CPU LGA2011-v3, 2.6GHz 35MB (Refurbished)

Intel Xeon E5-2697 v3 is a 14-core Haswell server processor offering robust multi-threaded performance at 2.6GHz with 35MB cache, delivered as a certified refurbished LGA 2011-v3 CPU.

This renewed Intel processor is aimed at servers and workstations that need many physical cores and dependable throughput without the new-unit price. It’s a Haswell-generation Xeon with 14 physical cores, a large shared cache, and QuickPath Interconnect bandwidth tuned for multi-socket systems. The unit you receive is refurbished, inspected, and backed by a minimum 90-day warranty, making it suitable for upgrades, system rebuilds, or spares in enterprise and lab environments.

How does this CPU improve multi-threaded workloads?

The E5-2697 v3 provides 14 physical cores and high cache capacity to keep many simultaneous threads fed with data, which benefits virtualization, batch processing, and compute clusters. Its Haswell microarchitecture also improves instruction throughput compared with older generations, yielding better efficiency under parallel loads.

• 14 physical cores for broad parallelism across applications
• 35MB shared cache to reduce memory latency for threads
• 9.6 GT/s QPI for fast inter-socket communication in multi-CPU systems

Is this processor compatible with my motherboard and system?

The CPU fits motherboards with the LGA 2011-v3 socket and firmware that supports the E5-2600 v3 family. Confirm your board’s socket and BIOS revision before installation; many server and workstation boards list supported CPUs in their documentation.

• Socket: LGA 2011-v3 — ensure exact socket match
• BIOS: firmware must enumerate Haswell-EP family CPUs
• Power and cooling: design TDP is 145W — verify your cooler and PSU

What should I expect from a certified refurbished unit?

Certified refurbished means the processor has been tested for full functionality and cosmetically inspected. It’s cleaned, repackaged, and shipped with any necessary accessories; this listing includes a minimum 90-day warranty for basic coverage against defects discovered after purchase.

• Functionality testing to confirm operation under load
• Basic cleaning and inspection for usable condition
• Repackaging and included accessories where applicable
• Minimum 90-day warranty for buyer protection

How does power and thermal behavior affect deployment choices?

With a 145W TDP, cooling and power delivery should be planned for continuous heavy use. Proper heatsinking and airflow in a chassis are important to maintain stable performance, particularly in dense rack or multi-socket configurations.

• TDP: 145W — select an appropriate cooler and thermal solution
• Server chassis: ensure adequate airflow or active cooling per socket
• Power supply: account for total system draw including multiple CPUs and GPUs

Who is this for? System builders, IT professionals, and lab engineers who need a high-core-count Xeon at a lower price point will find this refurbished E5-2697 v3 attractive. It’s well-suited to virtualization hosts, rendering or compile farms, database nodes, and any environment that benefits from many physical cores and large cache, provided the target motherboard supports LGA 2011-v3 and adequate cooling is in place.
