## Summary description

The HPE Intel Xeon Silver 4214R processor operates at 2.4 GHz and features 16 cores with a 16.5 MB L3 cache. It supports a maximum internal memory of 1.02 TB and utilizes DDR4-SDRAM across six memory channels. Designed for server environments, this processor offers scalability for 2S configurations, ensuring robust performance for demanding applications.

## Long description

The HPE Intel Xeon Silver 4214R is a server processor operating at a base frequency of 2.4 GHz with a stated boost up to 3.5 GHz and a 16.5 MB L3 cache. Built on the Cascade Lake microarchitecture and designed for LGA 3647 (Socket P) platforms, it supports DDR4-SDRAM across six memory channels and a maximum supported internal memory of 1.02 TB. Intended for use in server and workstation environments, this CPU is compatible with scalable 2-socket (2S) configurations and integrates into HP Enterprise systems.
Advantages
The processor combines multiple cores with a moderate base clock and higher boost frequency to balance parallel throughput and single-thread responsiveness. Support for six-channel DDR4 memory and a high maximum memory capacity enables large in-memory datasets and virtualization density. Its Cascade Lake design offers enterprise-class reliability and compatibility with server motherboards that use the LGA 3647 socket.
Suitable for
Virtualized server hosts and hypervisor platforms
Database workloads with large memory footprints
Compute-dense applications in 2-socket server systems
Application and web servers requiring consistent multi-core performance
Key specifications
Base frequency: 2.4 GHz; boost frequency: up to 3.5 GHz
Cores: 16 physical cores for parallel processing
Cache: 16.5 MB L3 cache
Memory support: DDR4-SDRAM across six memory channels
Maximum internal memory support: 1.02 TB
Socket: LGA 3647 (Socket P)
Processor family: Intel Xeon Silver (Cascade Lake)
How to use
Install the processor into a compatible LGA 3647 motherboard following the server or workstation manufacturer’s installation instructions, using appropriate thermal interface material and a cooling solution rated for server CPUs. Configure the system BIOS/UEFI to recognize the processor and set memory parameters in accordance with the six-channel DDR4 topology. For multi-socket deployments, ensure platform firmware and chassis are validated for 2-socket operation and that power and cooling meet the server specifications.
Usage recommendations
For stable operation, pair the CPU with ECC DDR4 memory modules matched to the motherboard’s supported speed and populate memory channels symmetrically. Use enterprise-class cooling and power delivery in rack or tower servers, and apply the vendor-recommended firmware and microcode updates to maintain compatibility and security.
