How to Increase the Memory Limit for 32-bit Applications in Windows 64-bit OS

If you are using a 32bits Windows, you are stuck with 32 bit applications and the amount of RAM that it can utilize. The only way is to upgrade the OS to 64 bit.

How much RAM can a 32-bit application use?

One bit in the register can reference an individual byte in memory, so a 32-bit system can address a maximum of 4 gigabytes (4,294,967,296 bytes) of RAM. The actual limit is often less – around 3.5 gigabytes – since part of the registry is used to store other temporary values besides memory addresses.

How can I use more than 4GB RAM on a 32-bit system?

To support more than 4 GB memory Windows uses Physical Address Extension (PAE). It uses paging tables to map the memory greater than 4 GB. By doing this the physical address size is increased to 36 bits, or 64 GB. PAE is used in 64-bit OS'es as well; in this case the maximum size is doubled to 128 GB.

Do 64-bit applications use more memory?

However, a common question is, does the 64-bit version actually use more memory than the 32-bit counterpart? The answer is yes, but it's generally only a small difference, maybe 100MB of extra memory space. ... Additionally we use 64-bit memory addresses instead of 32-bit memory addresses.

How much RAM can a 64-bit program use?

Remember that 64-bit Windows 10 Pro, Enterprise, and Education will support up to 2TB of RAM, while the 64-bit version of Windows 10 Home is limited to only 128GB.

Does 32 bit run faster?

Short answer, yes. In general any 32 bit program runs slightly faster than a 64 bit program on a 64 bit platform, given the same CPU. ... Yes there may be some opcodes that are only for 64 bit, but in general the substitution for 32 bit will not be much of a penalty. You will have less utility, but that may not bother you.

How much RAM can a 32 bit Windows 10 use?

Operating SystemMaximum Memory (RAM)
Windows 10 Home 32-Bit4GB
Windows 10 Home 64-Bit128GB
Windows 10 Pro 32-Bit4GB
Windows 10 Pro 64-Bit2TB

Why can't 32-bit use more than 4GB?

Natively, a 32-bit processor can only handle 4 GiB of RAM, since there are only 2 ^ 32 = 4,294,967,296 different numbers that can be represented using 32 bits. Whenever you store something in the memory, you need to save the address to be able to read or manipulate it.

Does 32-bit Windows use less RAM?

32-Bit Operating System is more lean and demands less system resources to run. As the 32-bit OS is only to run 32-bit software, It only has to load 32-bit libraries, services etc. And 3 GB Ram is utilized. ... And did you know that most of the software you run on 64-bit, is 32-bit code in fact.

Can you install more RAM than maximum?

One of two things generally happens. The memory works, but is limited to the maximum amount supported by the motherboard, or the memory doesn't work at all. ... So when memory is installed with more addressable bytes than the controller understands, the best outcome is that only the lower portion of the RAM is used.

Do 64 bit applications run faster?

² Performing a 64-bit operation on a 64-bit operating system is faster than performing it on a 32-bit operating system - it would take at least 2 32-bit operations to perform the same thing. Stability wise there should be no difference between 64-bit and 32-bit applications.

Why are 64 bit programs bigger?

There are several reasons for the size discrepancy: 64-bit Windows contains a translation layer (Windows 32-bit on Windows 64-bit, or "WoW64") that allows it to run 32-bit software. 64-bit Windows also contains 32-bit versions of various programs (Internet Explorer) and libraries (in the WinSxS folder).

Why is 64 bit better?

Simply put, a 64-bit processor is more capable than a 32-bit processor because it can handle more data at once. A 64-bit processor can store more computational values, including memory addresses, which means it can access over 4 billion times the physical memory of a 32-bit processor. That's just as big as it sounds.
