Different Windows editions support different amounts of RAM, for example:
Windows Server 2008 R2 Standard: 32GB
Windows Server 2008 R2 Enterprise: 2TB
I'm curious about the impact, if any, of having more than 32GB of RAM on a Server 2008 R2 Standard box. Will performance suffer due to Windows having to manage more memory, despite not being able to utilise it?
This question assumes that no physical or architecture limits are being hit. I.e., Windows is well aware that the machine has >32GB RAM, but only 32GB is usable.
