HP Xeon DP E5640 2.66 GHz Processor Upgrade - Socket B LGA-1366

Intel Xeon processor 5600 series automatically regulates power consumption and intelligently adjusts server performance according to application demand, maximizing both energy cost savings and performance.

The secret to this surprising combination is Intel's new 32nm microarchitecture. Featuring Intel Intelligent Power Technology, it reduces energy cost over single core servers by automatically shifting the CPU and memory into the lowest available power state, while Intel Turbo Boost Technology intelligently adjusts performance to application needs.

In addition, built-in hardware-assisted virtualization technology with Intel Virtualization Technology FlexMigration (Intel VT FlexMigration) gives you the power and flexibility to virtualize different generations of Intel Xeon processor-based servers within the same virtualization pool, giving you the ability to migrate workloads to fewer servers at night to save energy.
