recently i faced some problem with my graphics card and had to remove it and switch to my motherboard's inbuilt one.since then i am seeing that my usable ram has changed from 4gb to 3.5 gb.the inbuilt graphics card has a memory of 1gb.
also my laptop has 2gb nvidia 720m in it.it has 64 bit windows 8 and face the same problem.i only get 3.73 gb usable out of 4 gb.
please help

Dear some portion of the RAM is reserved for the Windows OS that is why technically though we've 4GB of RAM but the available RAM will be less than the 4GB. So pl don't worry.

Your graphics card has very little to do with the System RAM in your computer. I have (Right Now) 32GB of RAM in my machine and 29GB of it is usable. This is in part due to how bytes are counted by the OS and reservations made by the OS. EasyLover is quite correct.

Take a look in your Taskmanager. Under Hardware Reserved you will most likely see 512 MB.
It has a lot to do with your GPU.
When you dont have a GPU installed you still need Ram for your Graphics, VRAM.
In your case most likely your onboard GPU uses system Ram, I guess.
In most cases you can set the amount it uses in the BIOS settings.
However, I guess you should also be fine with 3,5 GB of system RAM.
Vram is something not to neglect

An excellent point. Since most on-board GPU solutions rely on utilising your system RAM you can loose up to a GB of RAM or more as the system Reserve's it for the on-board GPU.

It is well known thing that RAM is shared with the GPU. What we are talking about it here

No it isn't, not in all cases. It is shared when you are using an onboard GPU and not a discreet video card. Since a Video card has its own RAM it does not need to rely on the system reserving portions of system RAM for the GPU's use.

Yes this is true and still it is known.

Well, maybe the thread starter wasnt aware of it.

All persons have very precisely answered the question of the initiator. I hope his query is satisfied.
