The was a distinct animal. While the standard 32-bit Developer Edition could run on 64-bit Windows via the WOW64 (Windows-on-Windows 64) emulation layer, the true "64-bit Developer Edition" was a native IA-64 build. Key Characteristics of the 64-bit Edition: | Feature | 32-bit Developer | 64-bit (IA-64) Developer | | --- | --- | --- | | Max Memory per instance | 2 GB (3 GB with /3GB switch) | 4 GB to 512 GB (theoretical) | | Processor Architecture | x86 | Itanium 2 (IA-64) | | Buffer Pool | Limited to 1.6-2.0 GB | Expanded to near physical RAM | | Plan Cache | 64 MB default | Up to 64 GB | | Compatibility | Backward with Win32 apps | Required recompiled 64-bit apps |
Introduction: A Glimpse into Database History In the ever-evolving landscape of data management, few releases have been as pivotal—or as polarizing—as Microsoft SQL Server 2000. Released to manufacturing in late 2000 and hitting general availability in early 2001, this version marked a turning point for Microsoft’s database ambitions.

However, if you are one of the rare souls maintaining a critical application tied to this specific IA-64 build, you have our respect—and our condolences. Your best strategy is to treat this edition as a temporary testbench, not a permanent environment. Begin migration planning immediately, and document every quirk of your code that depends on 64-bit SQL 2000’s unique behavior. The was a distinct animal
