Why it is bad to store the page file on a RAM disk? - Page 26

post #251 of 320
Hi All,

I think the "Yes, putting the pagefile on a RAM disk is ridiculous." is not 100% failproof as statement.

Let's suppose the PC is running Windows XP Pro x86, 32 bit with 4 Gb RAM installed. Usually only 3/3.2 Gb of that RAM is actually available.

However using some utilities such as Gavotte Ramdisk is possible to make available the 'hidden' ram as Ramdisk.
Now we have a system with 3.2 Gb of regular RAM and 800 MB of Ramdisk.
We did not deduce any Ram to the OS.

Why then, even following the first page explanation we should choose to put the ramdisk in a regular hard disk/ SSD supposing to customize the paging file as fixed at 700/800 Mb?

Setting the paging file to the ramdisk seems more logical in this scenario and leaving - let's say 50 Mb - as physical paging file in C:\..D:\.. just for reliability measure.

These edge cases have already been discussed in the thread (and I agree with them) smile.gif

Although I would highly encourage to upgrade to a more modern, 64-bit operating system as soon as possible.

If I may ask a question here. Lets say I have 32 GB of ram.
Lets also say I'm handling some sensitive information and I don't want that to end up in a page file, Like encryption keys and whatnot.
I've also heard that the page file is somehow required for some applications to start. Is this true?
I've seen recommendations to disable the page file when security is required. But if you were to place the page file in volatile memory, would that not solve the leakage of sensitive data to the page file?

Does it not make sense to place it in ram in this case?

No. The page file is not a security flaw in itself. It would be the fault of the application to store sensitive data plain in memory. there is also no guarantee that the data will exist or not in the page file. Additionally the only time you can see what is in the page file is by either pwning the machine or have direct offline access to it.

Furthermore, anything in RAM can be read by anyone who has pwned the machine, in this case they are already on the other side of the airtight hatchway and could do a whole lot worse.

If you are still worried, you can have Windows empty the page file at shutdown but there is not much point because the system has exclusive locks on all configured page files, requiring aforementioned pwnage to access by non Windows components.

Hello, I played Anno 1404 Venice online in local network, after a while I started getting warning, that I am running out of memory and I have to restart my Anno because it can't save my game properly. And then after some time the game just crashes to the desktop.If I quit and then load it again, after some time I get same message and the story begins again.
How to fix this?
I know that this is related with page file, I'm running windows 8 x64, I5 2,6ghz, 4gb RAM (LAPTOP).
My 8 years old cpu don't have this problem by the way, so it is strange thing.
Thank you for answers.

What is the size of your hard drive and how much free space does it have?

500 GB, 40 Gb free on C disk and 200 free on D disk
post #259 of 320
I should of asked this earlier, do you have a screenshot of the out of memory message?

Is that 200MB or 200GB on the D disk?

200gb free space, I don't have a picture I will try to make it if I can.
But it says that : Warning! Not enough memory to securely save your game, please save and restart your game .
Something like that, I read in some forums few people had same problem, but I don't know, no one said that they solved it.
Forgot to mention, I play online at local network.
Edit: I don't get that message now for a while, firs day it took 2 hours to get it, last day only 15 minutes, now after some time it doesn't appear.
But I think it would after some time and then i will take a pic.
