I have 4 gigs of DDR2 Ram installed on my windows seven pc. It shows that it has 4 gigs installed yet only 2.5 usable. Please help?

It's not your onboard video - onboard video at the most will be reserving 128MB (if that) ... if you're using an nvidia card, chances are the onboard is disabled automatically anyway.  Have you tried taking out your nvidia card and using only the onboard video (looks like you may have, but unsure if you were answering the post that suggested that).

How are you determining what is usable?

Does your system have an integrated video card?  Some memory may be allocated to that.

Have you installed the newest drivers for your motherboard?

Do you have 64-bit windows 7?
In XP 32-Bit 3GB is all you see if you have 4GB, expect windows 7 32-bit is the same.

on 32bit windows you only get 3.5GB , deducting memory for VGA card ( sharing memory in BIOS )

no it does not.


I have a Gforce8800 graphics card.

It shows this under my computer, properties 4.00 GB (2.50GB usable)

I'm certain it's your video card taking sharing RAM.  If you run a DXDIAG, I think you'll see that in the results.

Its not the graphics card.

I have many different users in my office that do not have any added cards, yet it still shows 2.50GB usable.

Drivers then?

Kruno DžoićSystem EngineerCommented:
make sure when you boot the PC that it sees 4096MB installed and 4096MB usable - your motherboard has to have all 4 usable otherwise Windows will not. 2 - try running MSCONFIG - you can hit the Windows Key + R to bring up the Run box - type msconfig and click OK. Click on the Boot tab (2nd from left) - then click "Advanced Options" - make sure "installed memory is unchecked otherwise it may be limiting your total amount windows can "see".

@ Kazik0, all the latest drivers are installed.

@M3rc74, I have already tried those solutions and it still gives the same result.

I am using windows 7 Pro.

So this is happening on more than 1 machine? With a 32-bit os the ram on the video card(s) will be subtracted from the amount of usable ram. If the system also has an integrated video card that has not been disabled it will also subtract from  windows usable memory. What is the bios showing for usable ram?

Think about this ... Windows 7 32-bit will only allow you 3.25GB - 3.5GB of usable RAM for normal hardware overhead.  Put in a 750MB video card, 32-bit Windows still must manage that device ... 3.25 - .75 = 2.5GB.

Ok, i have disabled the onboard video card.

STILL, it says 2.50 usable. any other solutions i can try?
Im sure that it is not the Video cards...

Since there is an onboard card re-enable it and remove the 8800 and see how much is usable then. My bet is that the usable ram increases. I normally run 7 64-bit with 8gb of ram and 2 1gb video cards(sli), awhile back for test purposes i installed 32-bit xp, my system had 1.75Gb of usable ram. 32-bit oses have a 4Gb max memory capacity, that max includes all the memory in the system not just the ram, but the bios memory, cpu cache, video memory, etc.

How are you sure that it is not your video card?  This is a very common place for memory to disappear to.

Could be some memory remapping feature in the bios, whats the make and model of the system?

Hey Jarrod,
You said it "wasn't completely accurate" (but partially?) ... what did you find out?
