Solved Question about setting custom pagefile size in Win 7

Specs: Windows 7 64 bit Ultimate, i7 4790 \ 32 GB's GSKILL 1600 DDR3
I'm running Win 7 64 bit Ultimate on a 120GB 850 EVO SSD. I have an i7 4790, and 32GB RAM on a Gigabyte GA H97 D3H mobo.

I was trying to set my pagefile size to 16GB. I go to Sys Properties > Advanced > Performance Settings > Advanced > Change and set Custom size at Initial 800 MB and Max at 16384 MB. I click Set and OK and it holds the Initial and Max values when I close out. (I re-check them and it holds those entries) But if you look below that under Total paging file size for all drives it shows
Minimum allowed: 16 MB and Currently allocated: 800 MB

So I'm not sure if it's actually utilizing 16 MB if needed, as it shows the currently allocated at 800 MB. Also, after making the changes, then saving and exiting out, when I re-check under Performance Options > Advance it shows Total paging file size for all drives as 800 MB

Before you say how I don't need a 16Gb pagefile with 32GB RAM, it's overkill, unnecessary, etc, etc, my machine is used for vid editing. I am constantly on the verge of maxing 32Gb and sometimes go over. I have 32GB to use 32Gb (and regret I can't go 64Gb) I use Sony Vegas and intentionally set DRP high (6 to 8 GB) as I constantly do Dynamic RAM previews. If I open a couple or several instances of Vegas to swap between projects, which I often do, then I can watch the RAM usage climb quickly. If I don't pay attention to it, it maxes and my system crashes. It's often just when it goes over the 32 GB mark, so that's why I'm questioning whether it's actually accessing the max amount set for pagefile. I'd expect it to start crawling first, but it just seems to crash instead. (Black screen, everything freezes, requiring a reboot)

So from what I'm seeing here, is the pagefile actually set correctly to use 16Gb if necessary?

It's set to use 16GB if necessary. But it is not efficiently set. Extending the swapfile, which it will do dynamically, is an expensive (in terms of time) operation that will lead to a fragmented swapfile (bad news).

If you are sure that you need a 16GB swapfile then why are you setting the initial size to 800MB? Set it to 16GB.

I wasn't aware that I should make the min and max the same. I guess it's my misunderstanding of how the pagefiel works. I thought if I set min to a lower value it would only first use whatever smaller amount it needs, then up to the max 16GB. But it sounds like it doesn't work that way. And I guess it doesn't have to be exactly 16, but in that larger size range for sure. Based on what you're saying then, I'll set the min also to match the max size I want.

Why do you still need a pagefile with this amount of memory installed. Are you apps using more than 32GB all together?

I have set pagefile to minimum (20mb or so) and it improves performance greatly. If many apps loaded I just watch the task manager performance memory monitor.

"did you even read the op?"

A little tact goes a long way - even "see original post" would have seemed a little less like beating the slaves.

Always pop back and let us know the outcome - thanks
