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.
Can 32-bit use more than 4GB RAM?
An application on a 32 bit OS can access of 4GB of address space. But this is virtual address space and has absolutely nothing to with the size of physical RAM. Most modern 32 bit processors have sufficient address lines to address 64GB of RAM.
Can 32-bit run 8gb RAM?
You can install 8 GBs on 32-bit system, but you won’t be able to use it. You need a 64-bit system to do that.

What is the highest amount of RAM you can have?
If a computer is running a 32-bit processor, the maximum amount of RAM it can address is 4GB. Computers running 64-bit processors can hypothetically handle hundreds of terabytes of RAM.
Is 64bit faster than 32-bit?
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.
How can I change 32-bit to 64-bit?
Step 1: Press Windows key + I from the keyboard. Step 2: Click on System. Step 3: Click on About. Step 4: Check the system type, if it says: 32-bit operating system, x64-based processor then your PC is running a 32-bit version of Windows 10 on a 64-bit processor.
