Windows 10 uses only 75% or 3/4 RAM
My PC has 4.00 GB RAM installed and since I am using windows 10, I have noticed in the Performance tab of Task Manager, that the allocated Memory is not more than 3.0 GB out of 4.0 GB. Why windows 10 restricts? It doesn't use 1 GB available for it and I must use this 1 GB. Most of the times (or even always) My allocated Memory is in range of (2.5 of 3.0). Frequently I get the message: "Your computer is low on memory" and this restriction is causing many open applications to crash and even entire system crash and reboot/restart. I must solve this problem in any cost and if not then I must uninstall windows 10 and go back to windows 7. I need your help.
Hi, you can't force Windows to use a specific amount of memory, and usually it will be using only part of your installed RAM.
I expect you know that where RAM demand exceeds available RAM, the paging file is used.
Can you check its settings and post a screenshot similar to this?
Do you have a video card that uses shared RAM? That will make less RAM available to you.
Assuming you are using 64 bit Windows, adding RAM is relatively cheap.
Good morning, @Erez
In addition to what dalchina requested, would you please post 3 additional screenshots, all from Task Manager. They will give us a good idea what is running and your memory picture.
The Performance Tab with Memory highlighted:
The Startup Tab. If you don't have all the columns I show, just right click any column header and check off the necessary columns.
The Details Tab. Again, if you don't have the columns I show, add them the same way. On this one, click the Working Set column so it will sort descending most used memory to least. Post just the first page.
I just opened Nvidia Control Panel and then System Information. In there I found Shared System Memory: 2029 MB. It's almost two complete gigabytes! As you said, this may restricts my RAM to be used not more than 75%.
I also have to tell you that I have only 3 partitions: C, D and E.
How did you open the three windows: System Properties, Performance Options and Virtual Memory?
EDIT: I succeed to open these three windows. In Virtual Memory window I see the column: Paging File Size (MB) shows "None" in all three rows for C, D and E under "Drive [Volume Label]" column. Also the "No paging file" radio button is checked and the others "Custom size" and "System managed size" are not checked.
Total paging file size for all drives:
Minimum allowed: 16 MB
Recommended: 1403 MB
Currently allocated: 0 MB
Hope this is enough information for you right now.
Erez, I don't have a Nvidia graphics card, but that sounds high. It;s not hogging all of it, but it will battle with the OS doing graphics work, like videos, movies, etc. Is there a way to reduce the shared? Say to 1GB (1048MB)? Somebody @dalchina who knows these cards should answer.
This reply was for Dalchina actually see my edited post.
That says you're not using a paging file, so Windows gets short of memory, can't page RAM to disk, and your system crashes. (Looking at it very simplistically). That's not the default setting- so I'm wondering why you disabled paging?
You should enable it.
You are NOT using the paging file. The memory is thrashing and crashing. Turn the System Managed size ON, and re-start the PC. Then check the memory displays in your first post.
As to the shared RAM- my Nvidia card has 2Gb dedicated and 4Gb shared.
That it shares RAM doesn't mean Windows can't use that RAM. Normally the video card won't be using that RAM.
Unless your card has no dedicated RAM and is an integrated video card, it's somewhat unlikely it will impinge on Windows at all.
This is something Windows manages. That's my very limited understanding, and I'm very happy for someone to add more or correct this.
