80552PG0962M2M - Intel Pentium 4 651 3.40GHz 800MHz FSB 2MB L2 Cache Socket LGA775 Processor

Intel?? Hyper-Threading TechnologyIntel?? Hyper-Threading Technology (Intel?? HT Technology) delivers two processing threads per physical core. Highly threaded applications can get more work done in parallel, completing tasks sooner.Intel?? 64Intel?? 64 architecture delivers 64-bit computing on server, workstation, desktop and mobile platforms when combined with supporting software.?? Intel 64 architecture improves performance by allowing systems to address more than 4 GB of both virtual and physical memory.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.Thermal Monitoring TechnologiesThermal Monitoring Technologies protect the processor package and the system from thermal failure through several thermal management features. An on-die Digital Thermal Sensor (DTS) detects the core's temperature, and the thermal management features reduce package power consumption and thereby temperature when required in order to remain within normal operating limits
