How many cores does the E5-2665 have?

The E5-2665 features 8 cores and 16 threads, making it suitable for parallel workloads and multi-threaded applications.

What is the power consumption?

The processor has a TDP (Thermal Design Power) of 115W, typical for high-performance Xeon processors of this generation.

What socket type does it use?

The E5-2665 uses the LGA2011 socket, designed for dual-socket server and workstation platforms.

Is this CPU still relevant for modern use?

The E5-2665 is EOL and considered legacy. While functional, modern processors offer significantly better performance per watt and compatibility with current software and virtualization technologies.

Does it support ECC memory?

Yes, the Xeon E5-2665 fully supports ECC (Error-Correcting Code) memory for improved data integrity in enterprise environments.

What are typical use cases?

Originally designed for high-performance workstations, technical computing, database servers, and virtualized data center environments requiring robust multi-core processing.

What is the maximum turbo frequency?

The E5-2665 can dynamically boost to approximately 3.1GHz under favorable thermal and power conditions.

Can this processor be used in a single-socket system?

While technically possible on some LGA2011 single-socket boards, the E5-2665 was optimized for dual-socket configurations.
