Today we were finally able to get our hands on the “preliminary” information about the maximum use of random access memory (RAM) with the new versions of Windows 8 and Windows Server 2012 for our operating system data base.

Generally it remains the case that the 32Bit (x86) versions of Windows 8 are able to address 4 GB memory maximum only. With older hardware, just around 3,2 GB RAM can be used by the operating system.
The Windows 8 PRO and ENTERPRISE editions now have been upgraded to a maximum of 512 GB usable memory.
The Standard Edition supports up to 192 GB.
