Intel Xeon E5 2643

High-Performance Dual-Socket Server CPU enabling Broadwell-EP refresh and maintenance with Intel Xeon E5-2643V4

The Intel Xeon E5-2643V4 (SKU CM8066002041500) is a Broadwell-EP, 14nm server processor designed for LGA2011-3 platforms where predictable per-core performance and lifecycle continuity are required. With 6 cores and 12 threads, it supports enterprise consolidation scenarios that depend on consistent clock behavior, ECC memory integrity, and stable platform firmware validation across legacy Xeon E5 v4 deployments.

Intel Xeon E5-2643V4 integrates DDR4 ECC support up to 2400MT/s using RDIMM/LRDIMM, enabling capacity scaling up to 1.5TB (platform dependent) for virtualization hosts and in-memory services on dual-socket boards. The CPU exposes 40 PCIe 3.0 lanes to maintain balanced I/O for NICs, HBAs, and NVMe backplanes via PCIe switching, while keeping latency and bandwidth characteristics aligned with established E5 v4 server architectures. This makes Intel Xeon E5-2643V4 well-suited for maintenance refresh cycles that must preserve existing storage and expansion topologies without redesigning the rack footprint.

Why Choose the Intel Xeon E5-2643V4?

Intel Xeon E5-2643V4 delivers a practical density-to-performance profile for dual-socket systems that prioritize high single-thread throughput and deterministic platform behavior over disruptive migrations. It supports scalable two-socket designs, enterprise RAS expectations, and a controlled upgrade path for mixed fleets where compatibility with LGA2011-3 components, DDR4 ECC memory, and PCIe 3.0 adapters is a deployment requirement.

Intel engineering focuses on validated server silicon with long-lived platform alignment, ensuring Intel Xeon E5-2643V4 integrates cleanly into established datacentre standards for manageability, ECC reliability, and hardware-assisted virtualization and security features on compatible systems.

Key Applications:

Dual-socket server refresh and maintenance
Virtualization hosts with ECC memory
Database and transactional services
Infrastructure security workloads
PCIe expansion for storage and networking

At Happyware - Server Hardware you benefit from non-binding offers tailored to your upgrade and maintenance schedules, and you can extend the warranty up to 6 years to secure long-term operation of Intel Xeon E5-2643V4-based systems in enterprise environments.
