erall total cost of ownership by reducing potential down time and increasing productive throughput by better utilization of the data center resources. Intel® 64 Architecture Intel® 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® Technology Enhanced Intel SpeedStep® Technology is an advanced means of enabling very high performance while also 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. Demand Based Switching (DBS) DBS is a power-management technology developed by Intel, in which the applied voltage and clock speed of a microprocessor are kept at the minimum necessary levels for optimal performance of required operations. A microprocessor equipped with DBS operates at a reduced voltage and clock speed until more processing power is required. This is achieved by monitoring the processor’s use by application-level workloads, reducing the CPU speed when it is running idle while increasing it as the load increases. This technology was introduced as Intel SpeedStep® Technology in the server marketplace. Intel® Flex Memory Technology Facilitates easier upgrades by allowing different memory sizes to be populated and remain in dual-channel mode. Execute Disable Bit Execute 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. Help protect your customers' business assets and reduce the need for costly virus-related repairs by building systems with built-in Intel Execute Disable Bit.
