System Paging File

[boeingaviation]

Hi There,

I was wondering if someone with more knowledge than me can assist.

I have 16GB DDR3 1600 Ram installed on Windows 7 SP1 64 Bit.

Here is a screenshot of my Paging file tab showing what's allocated:

C Drive = System Managed
X Drive (FSX) = System Managed
P Driver (Prepar3D) = System managed.

Can someone please clarify why I have 48GB of paging file enabled. My computer is running as it should and gaming is fine, however I don't have 48GB of RAM installed (if that's where Paging generates from), so why is that number so.....and should I manually set a custom amount.

Thanks in advance.

Look at it again. 48 MB not GB.

On my systems I just let Windows 7 manage pagefile and all memory process.

 

[boeingaviation]

Isnt 48977mb 48GB as 1000mb=1GB

 

[derekimo]

look at it again. 48 mb not gb.

 

[boeingaviation]

So is that normal to have that much on paging file or should i set a custom size?

boeing, as the description states, that is the combined (meaning as it is accounted for across all drives), system managed paging file system allocated. That allocation is managed by the system and is not relative to physical memory ,but virtual space available for paging use. And yes 48XXX MB is 48 GB. LaybackBear may not have had that 2nd cup of coffee yet.

Making a fresh pot as I post. I need some help getting my 3 brain cells working again.

A 48GB paging file does seem excessive. If you are running a SSD you can reduce the page file to 1GB or 2GB. You also have 16GB of RAM, so try a smaller page file size & see how you go.

Use the method that you have in first post & select Custom Size & remember that the setting requires MB so to get say 2GB you need to type in 2000MB.

So would I set all 3 of those drives in my screenshot which are currently "system managed" to 2GB each.

My Windows drive is on an SSD.

Not sure how it would ever get to 48 GB with only 16 GB of memory, the page file is usually the same as the amount of memory installed.

With 16 GB of memory or higher, I don`t even use a page file. (just my personal choice)

Never seen another drive other then C even use a page file.

But I have no clue what your P and X partitions are either.

Set each to 4 GB max.

The Windows drive is the most important, so try setting that at 2GB & see how you go.

Alternatively, if you don't want to reduce it that much you can type in the Recommended Setting or you could use that for the other drives.

My P partition is for prepar3d. X is for flight sim X.

So I would be quite safe to just turn the paging file off or set a custom size of 2GB for OS drive?

Paging file wasn't enabled on the X & P drives so I enabled it and set to "system managed".

Few things have been funny like this after doing my repair install a couple months ago using the COEM win 7 pro 64 bit download from Microsoft.

Everything however is running normally, and after the repair install I don't use a lot of ram compared to before where I was using almost 12GB sometimes whilst playing flight sim. Now max I've seen used is 5.5gb.

Hi Roy,

Thanks for that link. I've had a quick look at it so correct me if I'm wrong but I should have 1.5x the amount of installed RAM as the page file on C drive?

So for 16GB I could set a custom size of 24GB, or have I got that completely wrong?

There's nothing wrong with the pc at all working perfectly fine just a large page file.

 

[AddRAM]

If you enabled the page file on those partitions, then I would turn it back off, you don`t need it on those partitions.

24 GB is wayyyy tooooo much, set it to 8 GB on C, that is more then enough.

 

[chrysalis]

My OS has never set system managed anywhere near that high (and I also have 16 gig ram), my best guess is your system has at some point been under heavy memory pressure and the pagefile got enlarged as a result.

Also the 1.5x ram rule I dont follow anymore more, at least on desktops. Dont disable the pagefile but I suggest maybe a min of 2 and max of 8 gig dynamic size (or if on a hdd to avoid fragmentation set min/max both to 8gig).

...however I don't have 48GB of RAM installed (if that's where Paging generates from)..

The large size of your page file did not come from your amount of installed RAM; but, the recommended amount (24GB) is determined by the amount of RAM installed.

The large size of your page file DID come from somewhere. There are tools that you can use to try and find out why the file is that large. Process Monitor can show you what apps write to that page file. The default filters exclude the page file. Just change that filter to include the page file. Let us know if you need help doing that.

On my desktop (16GB RAM), the page file is managed by the OS.
It just sits at 1GB...
...unless I'm doing weird testing
(like 4000 tabs in Pale Moon)
...then I've seen the page file grow go to 60GB.

I do it simple and understand it simple.

I let Windows 7 manage memory and page file. The system will adjust the page file as needed.
If you have it set to system manage and you get a memory pop up means one thing.
What ever you are doing on your system needs more physical ram because the system is unable to correctly manage memory
according to the demand of the system. Do less at one time with your system or just add more physical ram. Done.

boeingaviation has 16 gigs of physical ram. He/she would have to be doing some serious things like CAD to worry about page filling.

If Windows 7 can't figure out how to use memory I sure as hell can't.
Yes I tried to out smart Windows 7 memory management, just like we did in XP. All I did is no improvements or I made it worse.
Maybe I'm just to dumb to out smart system manage memory.

It's most likely related to some heavy flightsim activity, looking at the name on that drive,

Lockheed Martin - Prepar3D

I can see something like that growing pretty large.

You hit the nail on the head Derek

I`m sure those 2 programs use a lot of memory, but 48 GB seems excessive, who knows for sure.
