Why is Windows using page file when RAM is available?

The Pagefile allows the computer to perform smoothly by reducing the workload of the physical memory, or RAM. Simply put, every time you open more applications than the RAM on your PC can accommodate, the programs already present in the RAM are automatically transferred to the Pagefile.

What is the best paging file size in Windows 7?

Ideally, your paging file size should be 1.5 times your physical memory at a minimum and up to 4 times the physical memory at most to ensure system stability.

Do you need a pagefile with 32GB of RAM?

The fact that the page file is full simply means that hard page faults are occurring. It is not necessarily good or bad, other than excessive page faulting will impact performance.

Does 64gb RAM need virtual memory?

64gb is just a waste of money (unless you’re also doing game streaming, photo/video editing or running multiple virtual machines). As for page file – set it to 500MB initial, 8GB max. With such amount of ram it will not be used anyway. It just needs to exist.

What if you have no paging file?

This can also cause problems when running software that requires a large amount of memory, such as virtual machines. Some programs may even refuse to run.

Why can’t I move the page file to a RAM disk?

As you probably realized after reading the last couple of paragraphs, moving the page file to a RAM Disk is counter-productive because the RAM Disk itself gobbles up some of the available system RAM.

What is a page file and what does it do?

The page file comes into play when Windows doesn’t have enough available RAM to load new data that it needs into RAM. When the system RAM is maxed out, the operating system will move data that isn’t being used at the moment into the page file on the hard drive.

What is the use of RAMDisk?
