I have a Dell PowerEdge 2600 server. &nbsp;Although it's 6 years old, it is very reliable and carries only a light load. &nbsp;<br />
It currently runs 32 bit Server 2003 R2. &nbsp;The processor is in the Intel Xeon x86 family.<br />

My question is, can I re-install Windows Server but instead use Server 2008 R2. &nbsp;I realize this is 64 bit and my processor is x86, so I wanted to ask the Experts before going forward.<br />

Thanks.

Can Dell Poweredge 2600 with x86 processor run Windows Server 2008 R2 x64?

Windows Server 2008 and Windows Server 2008 R2, based on the Microsoft Vista codebase, is the last 32-bit server operating system released by Microsoft. It has a number of versions, including including Foundation, Standard, Enterprise, Datacenter, Web, HPC Server, Itanium and Storage; new features included server core installation and Hyper-V.

Windows Server 2008

Servers are computing devices that are similar to desktop computers in that they have the same basic components, but are significantly different in size, configuration and purpose. Servers are usually accessed over a network, and many run unattended, without a computer monitor, input device, audio hardware or USB interfaces. Many servers do not have a graphical user interface (GUI), and are configured and managed remotely. Servers typically include hardware redundancy such as dual power supplies, RAID disk systems, and ECC memory, along with extensive pre-boot memory testing and verification. Critical components might be hot swappable, and to guard against overheating, servers might have more powerful fans or use water cooling.
