I have a laptop with Windows 10 Pro x32, built 18362.535.
CPU-Z shows that there is 4 GB RAM, confirmed by Resource Monitor.
Resource Monitor
But Resource Monitor shows 2129 Mb hardware reserved.
Task manager shows 4 GB Ram of which 1.9 GB is usable.
Task ManagerHow can we make the whole RAM capacity usable?

Hi,

type msconfig in RUN, and check Advanced options in Boot. Maybe there is something that is eating memory.

1) First make sure that RAM modules are in good condition
make a RAM stress test
2) See the settings of BIOS
3) If nothing from above works see the below link

Look at the properties of ćomputer. See what it reports about memory.
It might be that you are over allocating, reserving memory for graphics.

32bit limits you to 4GB.

Going to 64 bit could make it possible to upgrade with more memory.

What GPU do you use?

Googling for "2129 MB" RAM gives
Intel HD Graphics 630, Dedicated 128 MB, Shared 2001 MB, Up to 2129 MB

Not saying that is the video chip they have of course.

Just checked the GPU info.
It seems that GPU is using 1967 MB of RAM
An no strange thing in MSConfig.

Well, this GPU has not own RAM, thus it must use RAM from the normal memory. Thus you have only 1.9 GB usable, as those  2129 Mb are reserved for the GPU.

Understood Ste5an, where can we decrease the RAM amount for the GPU ?

It should be under the Properties button.

Seen, so if I have it right, the RAM for GPU can't be adjusted?

You may be able to adjust it in the bios however this could cause problems if not stability issues

Generally, increasing memory would be the advisable route

Your only option is to backup your data.
Buy more memory
install windows 10 x64
and reinstall your applications
restore your data
16Gb with 2GB dedicated to the graphics.

Most of the listed apps on the desktop are ......


you could reduce the aero, and color bit from 32 to 24/16
......

in short your are limited by the OS and available memory.

But you can't usefully add any more memory to a 32bit system, 4GB is the physical limit. So more memory alone won't fix this.

What you could do is try to use the 4GB you have smarter (Using PAE or /3GB) but TINSTAAFL, allowing the software to access higher memory addresses, if it's not designed to, can make everything less stable.  If you want more memory available then you have to allow Windows some freedom with hardware memory allocation and the best way of doing that is to switch to a 64bit version of Windows

Look into your BIOS/UEFI. Maybe you can set it there.

Thanks MASQ, I totally missed that this was a 32-bit system

Since it has Windows 10 32 bit it's probably a notebook rather than a laptop so unlikely you can physically add RAM anyway.

From https://www.intel.com/content/www/us/en/support/articles/000020962/graphics-drivers.html
The amount of graphics memory in use is dynamically allocated to balance the needs of the operating system and all running applications.

So you now have to look at the apps you are running or have been running since startup and find out which one needs so much video RAM.
