Windows Memory Limits

The table below describes the psychical memory limits supported by each Windows version. We want make sure our clients are aware of these limits as we begin to offer increased amounts of RAM across our server platforms.

Version32bit Limit64bit Limit
Windows 2003 Standard R2 4GB 32GB
Windows 2003 Enterprise R2 64GB (PAE) 1TB
Windows 2008 Web 4GB 32GB
Windows 2008 Standard 4GB 32GB
Windows 2008 Enterprise 64GB (PAE) 1TB
Windows 2008 Datacenter 64GB (PAE) 1TB
Windows 2008 Web R2 n/a 32GB
Windows 2008 Standard R2 n/a 32GB
Windows 2008 Enterprise R2 n/a 2TB
Windows 2008 Datacenter R2 n/a 2TB

We recommend that servers using more than 4GB of RAM install a 64bit operating system over a 32bit operating system with PAE support.
