For many programs the 32 bit version is fine. 4 GB and below it's the same. But if you run nearly all 32 bit programs the 32 bit system will be faster than using the 32 bit emulator. The difference would be if you might add ram or want to run 64 bit programs.4GB RAM
What are the RAM limits of a 32-bit operating system All 32-bit operating systems have a 4GB RAM limit.32-bit architectures are not limited to 4GB of physical RAM. The limitation is 32-bits (or 4GB) of VIRTUAL address space in a single process. It is quite possible for a 32-bit processor and operating system to support more than 4GB of PHYSICAL memory.

Can 4GB RAM run 64-bit : 4GB RAM. If you're running a 32-bit operating system with 4GB of RAM installed, you'll only be able to access around 3.2GB due to memory addressing limitations. However, with a 64-bit operating system, you'll have full access to the whole 4GB.

Is 32-bit or 64-bit better for 4GB RAM

As its name suggests, the 32 bit OS can store and handle lesser data than the 64 bit OS. More specifically, it addresses a maximum of 4,294,967,296 bytes (4 GB) of RAM. The 64 bit OS, on the other hand, can handle more data than the 32 bit OS.

Is 32-bit better for low RAM : 64-bit programs require more memory to run than their 32-bit versions. So on older 64 bit machines, with less RAM onboard – it makes more sense to run a 32 bit OS. That situation can easily be mitigated by installing more RAM. But if you don't have that luxury – then sticking with a 32 bit OS is your best recourse.

I would not run 64-bit Windows on a PC with 2GB of RAM and 32-bit Windows will have more room to work because it is smaller. Microsoft recommends a minimum of 1GB of RAM for 32-bit Windows 10 and 2GB for 64-bit.

Many 32-bit computers have 32 physical address bits and are thus limited to 4 GiB (232 words) of memory.

Should I use 32bit or 64bit for 4GB RAM

To fully use your 4GB, you want a 64-bit OS. A 32-bit OS can map 4GB, but much of that last GB will be “reserved” addresses, used for things like video RAM… Leaving you with access to only about 3GB of usable RAM. Go 64-bit.32-bit operating systems cannot address more than 4GB of RAM unless they have a feature like “Physical Address Extension” in Windows that allows the system to address a larger amount of RAM. A 32-bit OS without such a kludge will support 4GB at a maximum.The amount of RAM memory you need for your computer depends on the type of tasks you plan to perform. For basic everyday use such as web browsing and document creation, 4GB or 8GB is usually sufficient. For more intensive tasks such as gaming or video editing 16GB or even 32GB of RAM is better.

32-bit operating systems cannot address more than 4GB of RAM unless they have a feature like “Physical Address Extension” in Windows that allows the system to address a larger amount of RAM. A 32-bit OS without such a kludge will support 4GB at a maximum.

Why is 32-bit only 4GB RAM : By definition, a 32-bit processor uses 32 bits to refer to the location of each byte of memory. 2^32 = 4.2 billion, which means a memory address that's 32 bits long can only refer to 4.2 billion unique locations (i.e. 4 GB). In the 32-bit Windows world, each application has its own “virtual” 4GB memory space.

Does 3GB RAM exist : However, the average amount of RAM in devices grew quickly. In 2014, many premium devices had 3GB of RAM and 4GB became the de facto standard a couple of years later.

What is the max RAM for 32-bit Windows 10

4GB

Operating System	Maximum Memory (RAM)
Windows 10 Home 32-Bit	4GB
Windows 10 Home 64-Bit	128GB
Windows 10 Pro 32-Bit	4GB
Windows 10 Pro 64-Bit	2TB

Can too much RAM be bad Having too much RAM won't necessarily hurt your computer. But it is generally considered to be a bad purchasing decision, because having much more RAM than you actually use won't speed up your computer. Having too much RAM is more of a waste of money, because the excess RAM isn't being used.Who would use 128GB RAM in a laptop 128GB of RAM is definitely overkill for the overwhelming majority of users; there's simply no need for that amount of memory in a business laptop. However, there is a section of laptop users that will benefit from it.
