The HP 662254-B21 CPU Kit is tailored for HP ProLiant DL380 Gen8 servers, incorporating the Intel Xeon E5-2603 processor. This processor kit is designed for environments that require reliable server performance without the necessity for high-frequency multi-threading capabilities. With a base frequency of 1.80GHz across its four cores and a thermal design power (TDP) of 80W, it offers an optimal balance between processing power and energy efficiency. The E5-2603 supports 1066MHz memory, which aligns well with applications that do not demand high memory bandwidth but still benefit from the quick access to essential data, facilitated by a 10MB cache. This kit provides a solid foundation for running day-to-day server tasks, including file serving and running basic applications while maintaining a lower power consumption profile. It includes a processor, heatsink optimized for the DL380 Gen8 servers, and thermal paste, constituting a complete solution for upgrading or replacing the server's current CPU with a focus on operational efficiency and reliability.
