Microsoft Windows Server 2003 R2 Standard Edition x64 w/SP2 (DE) 10 Clients

Windows Server 2003 R2 Standard Edition x64 w/SP2 (DE) 10 Clients Windows Server 2003 x64 provides high performance for both 32-bit and 64-bit applications on the same system. The underlying architecture is based on 64-bit extensions to the industry-standard x86 instruction set, allowing today's 32-bit applications to run natively on x64 processors. At the same time, new 64-bit applications are executed in 64-bit mode, which processes more data per clock cycle, allows greater access to memory, and speeds numeric calculations. The end result is a platform that leverages the existing wealth of 32-bit applications while also providing a smooth migration path to 64-bit computing.

Windows Server 2003 R2 Standard x64 Edition, is well-suited for high-performance computing (HPC) clusters, Terminal Services, Active Directory data stores larger than 2 GB, databases, business applications, Internet Information Services (IIS) 6.0, and memory-bound applications that do not require more than four processors.

Windows Server 2003 R2 Standard x64 Edition, supports up to 32 GB of RAM on 1- to 4-way servers. Supported processors include:
- AMD Opteron
- AMD Athlon 64
- Intel Xeon with Intel EM64T
