Intel Xeon E5503 Nehalem-EP 2.0 GHz 2 x 256KB L2 Cache 4MB L3 Cache LGA 1366 80W BX80602E5503 Server Processor

The Intel dual-core Xeon processor E5503, with advanced technologies like Intel QuickPath Technology, Intel Virtualization Technology and Enhanced Intel SpeedStep Technology, helps you improve efficiency in your IT infrastructure with intelligent performance, automated energy efficiency, and flexible virtualization.

• ECC Memory SupportWith the integrated DDR3 memory controller, the Intel Xeon 5503 processor enables three channels of ECC DDR3 memory, resulting in up to 19.2 GB/sec memory bandwidth. Error Correction Code Memory uses additional bits to check data integrity and help to improve the quality of memory functions.
• Intel Virtualization Technology (VT-x)Increasing manageability, security, and flexibility in IT environments, virtualization technologies like hardware-assisted Intel Virtualization Technology (Intel VT) combined with software-based virtualization solutions provide maximum system utilization by consolidating multiple environments into a single server or PC. By abstracting the software away from the underlying hardware, a world of new usage models opens up that reduce costs, increase management efficiency, strengthen security, while making your computing infrastructure more resilient in the event of a disaster.
• 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.
• Execute Disable Bit (EDB)Intel’s Execute Disable Bit function can prevent certain classes of malicious “buffer overflow” attacks when combined with a supporting operating system. Execute Disable Bit allows the processor to classify areas of the memory where application code can execute and where it cannot. When a malicious worm attempts to insert code into the buffer, the processor disables code execution, preventing damage or worm propagation.
• Enhanced Intel SpeedStep TechnologyEnhanced 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.
