The HP 572140-B21 is a six-core AMD Opteron 2425 HE processor for Socket F (LGA-1207) servers. Running at 2.1 GHz with a 4800 MHz HT front-side bus, it delivers balanced performance with 3 MB L2 cache and 6 MB L3 cache per core. The HE (High Efficiency) designation targets power-constrained environments where thermal and electrical output matter. Compatible with HP ProLiant DL165, DL385, and other Socket F-based systems from that generation, this processor suits multi-socket server configurations in virtualization, database, and moderate-load compute workloads.
