Theoretical limits:
32-bit Windows: 4GB of system memory (including graphics)
64-bit Windows: 8TB

Real-world limits of each OS version:

Version Windows 7 Ultimate x64
192 GB
Windows 7 Enterprise x64
192 GB
Windows 7 Professional x64
192 GB
Windows 7 Home Premium x64
16 GB
Windows 7 Home Basic x64
8 GB
Windows 7 Starter
2 GB

For many users running Home Premium x64 and also Rampage motherboards with very large memory: 24GB/32GB/64GB - you will need to run Professional or Ultimate to make full use of the memory space.

What if you have W7 Ultimate 64bit on a Rampage 3 extreme and you install 24Gb of ram but only shows 16GB?
