How can I make my 4GB RAM usable?

The best possible for this is that maybe you are using a 32-bit version of your Operating system, switch to 64-bit and the problem would be fixed. But still, atleast 500 MB by default is used by the OS itself so you won't be using full of your RAM, If you have 4 GB, even on 64 bit it would show as 3.95 GB usable or so.

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

4GB. If you're running a 32-bit operating system then with 4GB of RAM installed you'll only be able to access around 3.2GB (this is because of memory addressing limitations). However, with a 64-bit operating system then you'll have full access to the whole 4GB.

What happens if you use 100% of RAM?

If the memory usage is close to 100%, this can slow things down a lot. This is because the computer will then try to use your hard disk as a temporary memory store, called swap memory. Hard disks are much slower than the system memory. You can try to free up some system memory by closing some programs.

Can I run 32gb on 4GB RAM?

Why is 4GB limited 32-bit?

Every byte of RAM requires its own address, and the processor limits the length of those addresses. A 32-bit processor uses addresses that are 32 bits long. There are only 4,294,967,296, or 4GB, possible 32-bit addresses. There are workarounds to these limitations, but they don't really apply to most PCs.

Is 4GB enough for Windows 10 64-bit?

How much RAM you need for decent performance depends on what programs you are running, but for almost everyone 4GB is the absolute minimum for 32-bit and 8G the absolute minimum for 64-bit.
