This article describes how system manufacturers can take advantage of hot-add memory support in the following Windows Server editions:

  • Windows Server 2008 R2, Enterprise Edition and Datacenter Edition
  • Windows Server 2008, Enterprise Edition and Datacenter Edition
  • Windows Server 2003, Enterprise Edition and Datacenter Edition

Physical Address Extension - PAE Design

Physical Address Extension (PAE) is an Intel-provided memory address extension that enables processors to expand the number of bits that can be used to address physical memory from 32 bits to 36 bits, through support in the host operating system for applications using the Address Windowing Extensions (AWE) API.
