Hot-add memory support in Windows Server
On x86-based and x64-based platforms, some Windows Server editions support hot-add memory, which allows ranges of physical memory to be added to a running operating system without requiring a system reboot. 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

Hot-add memory minimizes a common source of server downtime: requiring the server to be powered off and subsequently rebooted during memory upgrades. Hot-add memory allows ranges of physical memory to be added to a running operating system without requiring the system to be shut down. This allows an administrator to add memory to a running system to address existing or future needs for memory without incurring downtime for the system or applications.
Starting with Windows Server 2003 with Service Pack 1 (SP1), Enterprise Edition and Datacenter Edition supports hot-add memory on both x64-based and Intel Itanium-based 64-bit platforms.
Windows Server 2003, Enterprise Edition and Datacenter Edition support hot-add memory on x86-based ACPI platforms only.
