A 32Bit operation system supports up to 4GB of memory, however not all of it may be available for use by applications. If you only have 4GB of memory and do not plan to install any additional memory then I would install the 32Bit version as there is nothing to be gained by installing the 64Bit version.
How much RAM can Windows 7 32Bit recognize?
|Operating System||Maximum Memory (RAM)|
|Windows 7 Starter 32-Bit||2GB|
|Windows 7 Home Basic 32-Bit||4GB|
|Windows 7 Home Basic 64-Bit||8GB|
|Windows 7 Home Premium 32-Bit||4GB|
Can I use more than 4GB RAM in Windows 7 32 bit?
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. … It is PAE that allows access to more than 4GB of RAM.
Is 4GB RAM enough for Windows 7?
The most significant advantage of a 64-bit system is that it can use more than 4GB of RAM. Thus, if you install Windows 7 64-bit on a 4 GB machine you won’t waste 1 GB of RAM like you would with Windows 7 32-bit. … Moreover, it is only a matter of time until 3GB will no longer be enough for modern applications.
How much RAM can a 32 bit system 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 can I use 4GB RAM on Windows 7?

How much RAM does Windows 7 require?
If you want to run Windows 7 on your PC, here’s what it takes: 1 gigahertz (GHz) or faster 32-bit (x86) or 64-bit (x64) processor* 1 gigabyte (GB) RAM (32-bit) or 2 GB RAM (64-bit) 16 GB available hard disk space (32-bit) or 20 GB (64-bit)
Why can’t 32-bit use more than 4GB?
Because each byte of memory has to have an address. In a 32-bit operating system, an address is 32 bits long; thus, there are 2^32 possible addresses, which means there are 2^32 bytes = 4 GB.
How do I make all my RAM usable Windows 7 32-bit?
To fix this, follow these steps:
- Click Start , type msconfig in the Search programs and files box, and then click msconfig in the Programs list.
- In the System Configuration window, click Advanced options on the Boot tab.
- Click to clear the Maximum memory check box, and then click OK.
- Restart the computer.
How much RAM can 64 bit use?
64 bit computing
Modern 64-bit processors such as designs from ARM, Intel or AMD are typically limited to supporting fewer than 64 bits for RAM addresses. They commonly implement from 40 to 52 physical address bits (supporting from 1 TB to 4 PB of RAM).
Is 4GB RAM enough for desktop?
For anyone looking for the bare computing essentials, 4GB of laptop RAM should be sufficient. If you want your PC to be able to flawlessly accomplish more demanding tasks at once, such as gaming, graphic design, and programming, you should have at least 8GB of laptop RAM.
Does Windows 10 require more RAM than Windows 7?
Windows 10 uses RAM more efficiently than 7. Technically Windows 10 uses more RAM, but it is using it to cache things and speed up things in general.
Is 4GB RAM slow?
4GB of RAM is not nearly enough by today’s standards. It’s enough to get you by, but not enough to open multiple Google Chrome tabs or multiple applications. A mechanical hard drive is also very slow. You will see a significant speed boost when you upgrade to an SSD.
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.
What is 32-bit operating system?
32-bit is a type of CPU architecture which is capable of transferring 32 bits of data. It is the amount of information which can be processed by your CPU whenever it performs an operation.
How can I change 32-bit to 64-bit?
Determine 64-bit compatibility using Settings
- Open Settings.
- Click on System.
- Click on About.
- Check the Installed RAM details.
- Confirm the information reads 2GB or higher.
- Under the “Device specifications” section, check the System type details.
- Confirm the information reads 32-bit operating system, x64-based processor.
