The main disadvantage of 64-bit architectures is that, relative to 32-bit architectures, the same data occupies more space in memory (due to longer pointers and possibly other types, and alignment padding).It is commonly believed that native 64-bit applications are faster than 32-bit applications, but that's not always the case. In fact, some 64-bit applications are slower because data structures tend to be larger in 64-bit applications (again, due to the larger pointers) and moving them around can slow things down.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.

Can I use 64-bit in 2 GB RAM : As you can see, 2GB is the minimum RAM for a 64-bit installation. So the short answer is yes, you can run it.

Can 64-bit run 32gb RAM

The OS support doesn't change about supported RAM size. Your laptop can have up to 32 GB (2 block of 16 GB) RAM. If you have Windows 10 64 bit, all the RAM has to be read.

How much RAM can 64-bit use : A 64-bit register can theoretically reference 18,446,744,073,709,551,616 bytes, or 17,179,869,184 GB (16 exabytes) of memory.

Most importantly, 32-bit systems are slow in computing calculations due to the amount of memory available. Due to this, they render graphics slower and at a much lower quality as compared to their 64-bit counterparts.

A 64-bit processor is faster than 32 bit, in terms of superior performance or experience. But the other compatible applications/systems should also be configured on 64 bit.

Can 32-bit run 8 GB RAM

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.Running short of RAM causes increased disk activity, which slows down the PC. 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.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. Bear in mind that how much RAM your system supports, along with the type and speed, will depend on your motherboard.

4Gb should be more than enough for 64bit. 64 bit. With 32 bit, you can't use all of your 4GB. (you will only get about 3.2GB).

Is 64-bit good for gaming : A 64-bit system can have a positive impact on gaming, especially for modern and resource-intensive games. With a 64-bit operating system, games can access and utilize more memory, allowing for smoother gameplay and reducing the likelihood of performance issues caused by insufficient random-access memory (RAM).

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.

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.

The OS support doesn't change about supported RAM size. Your laptop can have up to 32 GB (2 block of 16 GB) RAM. If you have Windows 10 64 bit, all the RAM has to be read.16 exabytes

A 64-bit register can theoretically reference 18,446,744,073,709,551,616 bytes, or 17,179,869,184 GB (16 exabytes) of memory.

Is 64-bit good for 4GB RAM : Yes, but because the main advantage of using a 64-bit edition of Windows is the ability to use more than 4 GB of RAM, there isn't much point to installing a 64-bit OS if your system can only have 4 GB of RAM.
