Intel Xeon E-2456 Server Processor (E-2456) – 6-Core, 12-Thread, Up to 5.1GHz, LGA 1700, 18MB cache

The Intel Xeon E-2456 (E-2456) is an LGA 1700 server processor with 6 cores, 12 threads and boost clocks up to 5.1GHz. Built on Xeon E-2400 (Raptor Lake-E), with 18MB cache, it is aimed at small businesses running entry servers, NAS builds and workstations.

Reliable entry-server performance with ECC memory support.

Right-Sizing Server Compute Without Replacing the Platform

When a server runs out of CPU headroom, replacing the whole platform is rarely the cheapest option. Many teams can extend the life of existing hosts by upgrading to a higher-core processor that fits the same socket, or by adding a second matched CPU.

The Intel Xeon E-2456 delivers 6 cores and 12 threads on the LGA 1700 platform with 18MB cache and DDR5-4800 ECC, dual-channel memory support. That makes it a practical choice for virtualization, databases, file and web services, and homelab clusters built on Xeon E-2400 (Raptor Lake-E).

Cores, Clocks and Cache in Practice

With 6 cores, 12 threads, up to 5.1GHz and 18MB cache, the Intel Xeon E-2456 handles file serving, small databases and light virtualization with headroom. Power is rated at 80W TDP.

Platform and Connectivity

The LGA 1700 socket supports DDR5-4800 ECC, dual-channel and 20 PCIe lanes (PCIe 5.0 and 4.0). A discrete graphics card is required for display output.

Setup Instructions

How to Install the Intel Xeon E-2456

1. Confirm your server motherboard supports the Xeon E-2456 on the LGA 1700 socket and update BIOS/firmware first.
2. Power down, discharge static and remove the existing heatsink and processor carefully.
3. Align the CPU with the socket key, install it, apply fresh thermal paste and refit the heatsink to the specified torque.
4. Boot to BIOS, confirm cores and memory are detected, then load your hypervisor or OS and verify performance.
