Intel Xeon Gold 6438N Server Processor (Gold 6438N) – 32-Core, 64-Thread, Up to 3.6GHz, LGA 4677, 60MB L3 (Refurbished)

The Intel Xeon Gold 6438N (Gold 6438N) is an LGA 4677 server processor with 32 cores, 64 threads and boost clocks up to 3.6GHz. Built on 4th Gen Xeon Scalable (Sapphire Rapids, network-optimized), with 60MB L3, it is aimed at IT teams, MSPs and homelab builders upgrading or populating servers.

Proven server compute for upgrades, rebuilds and homelabs.

Getting More Out of Existing Server Platforms

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 Gold 6438N delivers 32 cores and 64 threads on the LGA 4677 platform with 60MB L3 and DDR5-4800 ECC, 8-channel memory support. That makes it a practical choice for virtualization, databases, file and web services, and homelab clusters built on 4th Gen Xeon Scalable (Sapphire Rapids, network-optimized).

Cores, Clocks and Cache in Practice

With 32 cores, 64 threads, up to 3.6GHz and 60MB L3, the Intel Xeon Gold 6438N handles virtual machines, containers and database workloads with headroom. Power is rated at 205W TDP.

Platform and Connectivity

The LGA 4677 socket supports DDR5-4800 ECC, 8-channel and 80 PCIe 5.0 lanes. A discrete graphics card is required for display output.

Setup Instructions

How to Install the Intel Xeon Gold 6438N

1. Confirm your server motherboard supports the Xeon Gold 6438N on the LGA 4677 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.
