<div class="content wysiwyg-content">
I am installing software on the server which requires a lot of RAM. The specs recommend 8 GB of RAM and Server 2003 Std. That is obviously wrong because Server 2003 Std only supports 4 GB maximum. Do I have to go with a x64 system (like Enterprise)? I am really reluctant about that because of the nightmare with drivers related to 64 bit. Thank you!

How can I have 8 GB of RAM

The Microsoft Legacy Operating System topic includes legacy versions of Microsoft operating systems prior to Windows 2000: All versions of MS-DOS and other versions developed for specific manufacturers and Windows 3/3.1, Windows 95 and Windows 98, plus any other Windows-related versions, and Windows Mobile.

Microsoft Legacy OS

The Microsoft Server topic includes all of the legacy versions of the operating system, including the Windows NT 3.1, NT 3.5, NT 4.0 and Windows 2000 and Windows Home Server versions.

Microsoft Server OS

Windows Server 2003 was based on Windows XP and was released in four editions: Web, Standard, Enterprise and Datacenter. It also had derivative versions for clusters, storage and Microsoft’s Small Business Server. Important upgrades included integrating Internet Information Services (IIS), improvements to Active Directory (AD) and Group Policy (GP), and the migration to Automated System Recovery (ASR).
