Windows 7: Not able to use all 4GB of ram

Not able to use all 4GB of ram

I have 4GB of ram installed on my pc but after installing my Nvidia PNY Geforce 9500GT 1GB GPU my pc now says I have 3GB of ram usable instead of the full 4GB it use to have, and my GPU now says it has 2GB physical memory to use instead of its 1GB its meant to have. I am running Windows 7 32bit and wanted to know how to stop it ram shearing with my GPU as I really want it to have the full 4GB back usable is there a way to fix this?

hi supernova, and welcome to sevenforums,

unfortunately you are never going to get to use your full 4 gigs ram with 32 bit windows. it just isn't possible.

You should have Gone for x64 if you wanted to use that much memory, there is no other way around it and as far as your Graphics card goes with sharing memory, it's not dedicated so it will only use it if it needs to and as you have 1Gig of dedicated graphics memory it would be highly unlikely that it would need to share any of your system memory.

The fact that it says you only have 3GB usable has nothing to do with your Graphics card using the other Gig, in fact the memory your Graphics card is sharing from is the remaining usable 3GB of system memory the fact is the extra 1GB is not usable at all and that is because of the limitations of running 32bit, the maximum total amount of RAM it can handle is 4 Gigs and that includes Graphics Memory.

If you're sharing system RAM with video, it doesn't matter which version you install... a-b=c

What output does your machine produce from running BCDEDIT on an elevated (run as admin) command prompt?

Right-click the CMD.EXE (command prompt) short-cut.

Choose "run as admin". If you get a security prompt, click "Yes". You should now see a command prompt (white text on a black background).

Type "BCDEDIT" without the quotes. Look at the output.

I'm interested in whether the word "removememory" is mentioned anywhere. If so, that may be at least contributing to your problem, especially if the same condition was present during your machine's 64-bit days when you observed the same "missing RAM" symptom.
