  2. 3 GB barrier - Wikipedia

    en.wikipedia.org/wiki/3_GB_barrier

    Many 32-bit computers have 32 physical address bits and are thus limited to 4 GiB (2 32 words) of memory. [3] [4] 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, [5]: 445 which allows addressing up to 64 GiB (2 36 words) of memory.

  3. 2 GB limit - Wikipedia

    en.wikipedia.org/wiki/2_GB_limit

    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]

  4. RAM limit - Wikipedia

    en.wikipedia.org/wiki/RAM_limit

    The 386DX had 32-bit addressing, allowing it to address up to 4 gigabytes (4096 megabytes) of memory. The Motorola 68020, released in 1984, had a 32-bit address space, giving it a maximum addressable memory limit of 4 GB.

  5. Physical Address Extension - Wikipedia

    en.wikipedia.org/wiki/Physical_Address_Extension

    32-bit versions of Microsoft Windows support PAE if booted with the appropriate option. According to Microsoft Technical Fellow Mark Russinovich, some drivers were found to be unstable when encountering physical addresses above 4GB. [16] The following table shows the memory limits for 32-bit versions of Microsoft Windows:

  6. 32-bit computing - Wikipedia

    en.wikipedia.org/wiki/32-bit_computing

    A 32-bit register can store 2 32 different values. The range of integer values that can be stored in 32 bits depends on the integer representation used. With the two most common representations, the range is 0 through 4,294,967,295 (2 32 − 1) for representation as an binary number, and −2,147,483,648 (−2 31) through 2,147,483,647 (2 31 − 1) for representation as two's complement.

  7. Windows NT 4.0 - Wikipedia

    en.wikipedia.org/wiki/Windows_NT_4.0

    The maximum amount of supported physical random-access memory (RAM) in Windows NT 4.0 is 4 GB, [34] which is the maximum possible for a 32-bit operating system that does not support PAE. [35] By comparison, Windows 95 fails to boot on computers with more than approximately 480 MB of memory. [36]

  9. Windows XP Professional x64 Edition - Wikipedia

    en.wikipedia.org/wiki/Windows_XP_Professional_x...

    The primary benefit of moving to 64-bit is the increase in the maximum allocatable random-access memory (RAM). 32-bit editions of Windows XP are limited to a total of 4 gigabytes. Although the theoretical memory limit of a 64-bit computer is about 16 exabytes (17.1 billion gigabytes), Windows XP x64 is limited to 128 GB of physical memory and ...
