While the maximum RAM limit for 32-bit Windows 7 editions is 4GB, when it comes to the 64-bit editions, the amount of memory that the OS can address depends on which edition you are running.
Can Windows 7 32-bit use more than 4GB of RAM?
While the motherboard can support 8GB or RAM, 32bit Windows can only support 4GB. You would have to go to 64bit Windows to have support for more than 4GB RAM.
How much RAM can 32bit Windows use?
Yes, on a 32bit machine the maximum amount of memory usable is around 4GB. Actually, depending on the OS it might be less due to parts of the address space being reserved: On Windows you can only use 3.5GB for example. On 64bit you can indeed address 2^64 bytes of memory.
How much memory can 32-bit support?
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 around 3.5 GB since part of the register is used to store other temporary values besides memory addresses.
Can Windows 7 32-bit run 8GB of RAM?
While the maximum RAM limit for 32-bit Windows 7 editions is 4GB, when it comes to 64-bit editions, the amount of memory that the OS can address depends on which edition you are running. … Here are the upper RAM limits for the different editions of Windows 7: Starter: 8GB. Home Basic: 8GB.
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.
Why can’t 32-bit use more than 4GB?
Natively, a 32-bit processor can only handle 4 GiB of RAM, since there are only 2 ^ 32 = 4,294,967,296 different numbers that can be represented using 32 bits. Whenever you store something in the memory, you need to save the address to be able to read or manipulate it.
How can I use more than 4GB RAM on a 32-bit system?
To support more than 4 GB memory Windows uses Physical Address Extension (PAE). It uses paging tables to map the memory greater than 4 GB. By doing this the physical address size is increased to 36 bits, or 64 GB. PAE is used in 64-bit OS’es as well; in this case the maximum size is doubled to 128 GB.
How do I make all my RAM usable Windows 7 32-bit?

What is the maximum usable memory by 32-bit operating system * 16 GB 8 GB 4 GB 2 GB?
In any 32-bit operating system, you are limited to 4096 MB of RAM simply because the size of a 32-bit value will not allow any more. On a 32-bit system, each process is given 4 GB of virtual memory to play with, which is separated into 2 GB of user space that the application can actually use at a time.
Is 4GB RAM 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. So there’s a good chance that your problem is caused by not having enough RAM.
