Windows 7: Pagefile.sys

Pagefile.sys

I'm running Windows 7 Ultimate 64bit with 8GB of RAM. Is it necessary to set a specific number for the pagefile.sys? Right now I have it set to "No paging file".

Please advise.

Thanks all.

Welcome to SF!

Many people advise that the paging file should be the same size as your memory. In your case, they would recommend making the paging file 8GB.

It's not mandatory to have a pagefile...for most applications. Although rare, there are some apps which might refuse to run without any virtual memory defined. But like I said, rare these days.

I don't usually run my boxes without a paging file. I figure that drive space is cheap (unless it's SSD space)...so why not just have a page file in case you ever do need it.

Most people recommend 2x your physical RAM when you have less than 1GB of RAM. Since you have 8GB, you likely won't want more than about 1x your RAM or 8GB for your pagefile.

Over 4GB = you don't need a pagefile under 2GB = You need a pagefile and it should be set to double your RAM.

The pagefile needs to be set according to your needs. Theoretically you could use an entire hard drive as your page file but do you really need that much ram?

With 8GB of ram the pagefile will be more just a place for windows to store some less used stuff from the kernel and if your ram fills up it will start swaping stuff to the pagefile from your RAM. So do you really need it to be 8-16GB in size? I dont think so but hey... disc space is cheap.

I prefer to turn it off. Who want's anything being put to a slow hard drive over fast RAM?

Well the truth is that Windows 7 will only put the inactive things on the Page File, so you should never see performance decrease.

I guess the possible exception is if the page file is so large it makes the drive tight on space.

I like to keep a pagefile, but to keep if from interfering with defrag, I like to make a small dedicated partition for it all to itself.

You should set it to "System Managed" and leave it alone.

I have been doing the same for years.

Until you go to access said inactive things... bam instant slow computer. No thanks.
