Memory management stress testing: Lol, I love 7

@DisplayName:

That being said, what's the optimal amount to allocate for virtual memory? Is "system managed" just fine or a custom size is better?

Haha I love the first picture... how many programs is that in total?

Good explaination on the PageFile, i have the same question as Djnx, i always thought that it was supposed to be 1.5x-2x your ram, probably less if you have a ton of ram..

i've got 2 gigs and mine is set to 2048-4096, too much?

I have 2 gb and I've set mine to 1000 mb. Been running like that for a month now with no problems. Before deciding I ran Pagefile Usage Monitor for a while and ran my computer under heavy load. The pagefile never went over about 600 mb.

I just checked how W7 set up virtual memory on my 4 GB x64 system and it automatically set the page file at 4030 (the same as my system ram).

Also would like to add my thanks to the poster earlier in this thread who gave the best explanation I have seen on the function of the page file and why it should be kept enabled in Vista and 7.

Just use the page file monitor as mentioned before to decide an optimum size. Although, usually the default is just fine.

In my case, I just leave it at 2GB or at 1x RAM if higher. But, I keep minimum and maximum the same to avoid it getting fragmented.

I read in the engineering blog that the W7 rc default PF size is automatically set at 100% of system ram. It's working fine for me. My machine has never been faster or more stable. I see no reason to change anything.

Very good dialogue. One question

I have Windows 7 build 7100 with 2 gigs of memory . I disabled the Page File adn rebooted but task manager still shows substantial cached memory. Were is the OS caching this data?

It shows you where in system control panel. This isnt memory, its hard disk space set aside for when you need it. With inly 2 gigs of ram you need it.

Sorry but I did not quite understand your response. I have shut down virtual memory by setting the page file to zero. This is what shows in control panel


But when I look at task manager it continues to show cached memory

the page file is not (or related to) cache memory...

Disable SuperFetch and/or ReadyBoost to adjust this - highly NOT recommended.

What is the aim - what would you like to accomplish?

As an aside, pagefiles are not synonymous with "virtual memory". You can run without pagefiles, though it's a misguided idea in the vast majority of cases, but you can never get rid of virtual memory. Those two concepts operate on different levels.

"Cached" in this context means physical memory used by the OS to predictively preload what it thinks you're likely to use next (superfetch).
