Intel Pentium 4, Xeon, or AMD Athlon/Opteron minimum.

To exceed the 32-bit limit, Oracle implemented support for AWE, a Windows API that allowed 32-bit processes to map physical memory beyond 4GB into a window. However, AWE memory could only be used for the database buffer cache, not for shared pool, large pool, or Java pool. This fragmented memory management meant DBAs had to carefully partition SGA between AWE-eligible and non-AWE regions. Performance suffered because AWE memory required direct OS paging, and context switching between windowed mappings was slower than native 64-bit flat addressing.
