Why Choose This Product?

• Designed for DL380 Gen9: HPE explicitly lists 817951-B21 as the DL380 Gen9 E5-2680 v4 Processor Kit, giving buyers a platform-specific upgrade option. 
• 14-core compute capacity: Fourteen physical cores provide meaningful parallel-processing capability for multi-threaded server applications.
• 28-thread execution: Hyper-Threading increases the number of logical processors available to supported workloads, particularly useful in virtualization environments. 
• Balanced clock and core design: A 2.40 GHz base frequency combined with up to 3.30 GHz Turbo provides a practical balance between sustained throughput and burst performance. 
• 35 MB cache: The large Smart Cache helps support data-intensive processing by keeping frequently used information closer to the CPU. 
• Dual-CPU scalability: The DL380 Gen9 supports up to two processors, allowing buyers to build a dual E5-2680 v4 configuration where the platform and workload justify additional CPU capacity. 
• Simplified deployment: The HPE kit includes a High Performance Heatsink, reducing the number of cooling components that need to be sourced separately for the processor installation. 
• Infrastructure lifecycle value: For organizations already operating DL380 Gen9 systems, upgrading or replacing a compatible processor can extend the productive life of existing server hardware and avoid an unnecessary full-platform replacement.
