AT80573KJ1006M - Intel Xeon X5270 Dual Core 3.50GHz 1333MHz FSB 6MB L2 Cache Socket LGA771 Processor

Enhanced Intel SpeedStep?? TechnologyEnhanced Intel SpeedStep?? Technology is an advanced means of enabling high performance while meeting the power-conservation needs of mobile systems. Conventional Intel SpeedStep?? Technology switches both voltage and frequency in tandem between high and low levels in response to processor load. Enhanced Intel SpeedStep?? Technology builds upon that architecture using design strategies such as Separation between Voltage and Frequency Changes, and Clock Partitioning and Recovery.Intel?? Demand Based SwitchingIntel?? Demand Based Switching is a power-management technology in which the applied voltage and clock speed of a microprocessor are kept at the minimum necessary levels until more processing power is required. This technology was introduced as Intel SpeedStep?? Technology in the server marketplace.Execute Disable BitExecute Disable Bit is a hardware-based security feature that can reduce exposure to viruses and malicious-code attacks and prevent harmful software from executing and propagating on the server or network.
