Should i use pae

If the computer does not support hardware-enabled DEP or is not configured for hot-add memory devices in memory ranges beyond 4 GB, PAE must be explicitly enabled. When neither 4GT nor AWE are being used, the amount of physical memory that a single bit process can use is limited by the size of its address space 2 GB. In this case, a PAE-enabled system can still make use of more than 4 GB of RAM to run multiple processes at the same time or to cache file data in memory.

However, some versions of Windows limit the maximum amount of physical memory that can be supported when 4GT is used. On such systems, booting with 4GT enabled causes the operating system to ignore any memory in excess of the limit.

The PAE will now be fully enabled on your computer. How do I enable PAE? First check if PAE is enabled. To do this, right-click My Computer, and select Properties. Look under the Computer Processor information, and if Physical Address Extension is listed there, then it is enabled.

Does Windows 10 support PAE? The short answer is that yes, Windows 10 requires that your processor supports PAE. While the maximum RAM limit for bit Windows 7 editions is 4GB, when it comes to bit editions, the amount of memory that the OS can address depends on which edition you are running. Home Basic: 8GB. In PAE mode, MMU tables map bit virtual addresses to bit physical addresses, with a three-level table unlike non-PAE mode where the MMU tables map bit virtual addresses to bit physical addresses with a two-level table.

No-eXecute NX is a processor feature that allows memory pages to be marked as non-executable. The maximum amount of memory that can be supported on Windows Server is 4 GB. From the sound of it, you have a bit machine that has bit libraries for backwards compatibility. Category: technology and computing operating systems.

Save the file and then restart your computer. Server Fault is a question and answer site for system and network administrators. It only takes a minute to sign up.

Connect and share knowledge within a single location that is structured and easy to search. I'm having a relatively new hardware i5 CPU x64 with a legacy 32 bit Windows 10 install. It is running older company software so the upgrade to 64 bit is not practical for several reasons. I know that for longer time the 32 bit Windows had the option in some cases to enable PAE Physical Address Extension to increase the 32 bit address limit to 36 bits. See this:. I need more memory.

This is the desktop version of the OS. However the memory limit stays 4 GB after reboot. Msconfig and disabling max memory option does not help either.

So the 8 GB memory can be seen by the hardware and the OS. The official Microsoft document about client OS limitations is here. If the memory is remapped, X64 Windows can use this memory. Sign up to join this community. The best answers are voted up and rise to the top.
