The 2 GB limit refers to a physical memory barrier for a process running on a 32-bit operating system, which can only use a maximum of 2 GB of memory. [1] The problem mainly affects 32-bit versions of operating systems like Microsoft Windows and Linux, although some variants of the latter can overcome this barrier. [2]
Physical address limits. Many 32-bit computers have 32 physical address bits and are thus limited to 4 GiB (2 32 words) of memory. x86 processors prior to the Pentium Pro have 32 or fewer physical address bits; however, most x86 processors since the Pentium Pro, which was first sold in 1995, have the Physical Address Extension (PAE) mechanism,: 445 which allows addressing up to 64 GiB (2 36 ...
However, "client" versions of 32-bit Windows (Windows XP SP2 and later, Windows Vista, Windows 7) limit physical address space to the first 4 GB for driver compatibility even though these versions do run in PAE mode if NX support is enabled. Windows 8 and later releases will only run on processors which support PAE, in addition to NX and SSE2.

Using a supported operating system and web browser is key to having the best experience with AOL products and services. While Internet Explorer may still work with AOL Mail, it's no longer supported by Microsoft and can't be updated. For a more reliable and secure experience with AOL products, we recommend you download a supported web browser.
v. t. e. In computer architecture, 32-bit computing refers to computer systems with a processor, memory, and other major system components that operate on data in 32- bit units. [1] [2] Compared to smaller bit widths, 32-bit computers can perform large calculations more efficiently and process more data per clock cycle.
Limits on physical memory for 32-bit platforms also depend on the presence and use of Physical Address Extension (PAE), which allows 32-bit systems to use more than 4 GB of physical memory. PAE and 64-bit systems may be able to address up to the full address space of the x86 processor. See also. DOS memory management; Motherboard; References
On 32-bit systems, AWE depends on Physical Address Extension support when reserving memory above 4 GB. AWE was first introduced in Windows 2000 as a new API superseding the PSE36 method (from the Windows NT 4.0 Enterprise Edition) of accessing more than 4 GB of memory, which was no longer supported in Windows 2000.
