Kb 2885 __exclusive__ Page

KB2885 is a classic Microsoft Knowledge Base article that addresses a critical server configuration issue: enabling Microsoft SQL Server to address and utilize more than 2 GB of physical RAM on 32-bit versions of Windows Server. Important note: This KB is largely obsolete for modern 64-bit systems (x64) and SQL Server 2005 and later. However, it remains an informative historical reference and can still apply to legacy 32-bit SQL Server instances (SQL Server 2000, 7.0, or early 2005 on 32-bit OS). The Problem KB2885 Solves By default, 32-bit Windows imposes a 2 GB virtual address space limit per process (e.g., for sqlservr.exe ). Even if the physical server has 4 GB, 8 GB, or more RAM, SQL Server cannot directly use beyond ~2 GB without special configuration.
