What is the maximum amount of RAM a 32-bit installation of Windows will support?

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

What is the maximum amount of virtual memory a process can take up?

On 32-bit versions of Windows, a single process can map and address no more than 3GB of virtual memory at time. In 64-bit versions of Windows, a 32-bit process can map and address no more than 4GB of virtual memory at a time.

What limits virtual memory?

You can address more virtual memory than is available in your pointer-based address space using paging. Virtual memory upper limits are set by the OS: for example, on 32-bit Windows the limit is 16TB, and on 64-bit Windows the limit is 256TB. Virtual memory is also physically limited by the available disc space.

How much RAM can a 32-bit application use?

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.

What is the 32-bit limit?

A signed integer is a 32-bit datum that encodes an integer in the range [-2147483648 to 2147483647]. An unsigned integer is a 32-bit datum that encodes a nonnegative integer in the range [0 to 4294967295].

What is the minimum and maximum size of virtual memory?

This process is technically called Paging. Because the Pagefile works as a secondary RAM, many times it is also referred to as Virtual Memory. The minimum and maximum size of the Pagefile can be up to 1.5 times and 4 times of the physical memory that your computer has, respectively.

What should my virtual memory be set at 32GB RAM?

Microsoft recommends that you set virtual memory to be no less than 1.5 times and no more than 3 times the amount of RAM on your computer.

Can a 32-bit system use more than 4GB of RAM?

A 32 bits can address up to 4gb so a 32 bit os can not use more than 4gb of ram. Past that, a 32 bit os must reserve some ram for fixed buffers below the 32 bit line so you effective ram available will be less than 4gb. Likely something in the 3.5gb range, depending on the hardware installed.
