HP 600742-L21 Xeon L5630 2.13GHz Processor Kit

The HP 600742-L21 is a processor kit built around the Intel Xeon L5630, a quad-core chip from the Westmere-EP family clocked at 2.13GHz. Designed as a validated upgrade path for HP ProLiant DL320 G6 rack servers, it offers a straightforward way to boost server capability without overhauling the entire system. The "L" designation in the Xeon L5630 signifies its low-voltage design, drawing just 40W of power — roughly half that of standard-voltage Xeon 5600 series processors — which translates directly into lower electricity bills and reduced cooling overhead in dense data center environments.

With four cores, hyper-threading support for eight simultaneous threads, and 12MB of shared L3 cache, the L5630 handles typical server workloads such as virtualization, file serving, and web hosting with reliable efficiency. While it won't match the raw throughput of higher-clocked Xeon models, its strength lies in delivering consistent performance per watt. For organizations maintaining DL320 G6 servers and seeking an economical processor refresh that prioritizes energy efficiency, this kit provides a well-matched solution backed by HP's server validation and compatibility testing.
