i've recently got new PC and added 4gb RAM to it But in WindowsXP/Vista it shows RAM size as 2.99gb

i've following Configuration

CPU: Intel Core2 Quad 2.40 GHz q6600
M/b: Intel DG33 FB
RAM: Transcent 2x2gb 667
GPU: XFX GeForce 8600 GT

i dont understand weather my ram is faulty or it is shared with graphics.

idont think it is shared with graphics because the graphics memory is same as it is on the GPU (512mb)
 
I think it is shared with graphics memory and 32 bit operating systems can only use up to 4 gigs of memory. so you have 4.5 total

do you have it in 1 gig sticks or 2 gig sticks?
 
thanks dude but it cant be 4.5gb the 512 is not RAM its Graphics Memory.

my question is do every 32-bit OS giv 2.99GB of ram instead of 4gb?

well like i said your graphics memory is part of your system and your os can only use up to 4 gigs including your graphics memory. if you had 1 gig sticks i would say on stick might be faulty but you dont so my guess is your system cant recognize all 4 gigs due to the extra 512 you have for graphics memory.
 
I was just reading in another post that the GPU memory is separate, and has nothing to do with the limitations of 32byte OS. So, with 4G installed and available, I would guess that about 1G is being used as sort of 'overhead' and only about 3G is available.
Estimates I've seen suggest VISTA uses up about 512M, but other considerations may have increased this.
 
Your hardware configuration will have an effect on the total RAM that will show up in 32-bit windows. 32-bit Vista automatically limits the total RAM to 3.25GB but sometimes more address beyond that are needed and you end up with less RAM than that. It's a common thing.

Also that board has onboard video, unless it's disabled (as you have an addin card) some RAM will be taking from the system RAM pool and used as video RAM.

Video RAM is separate, but it still needs to be mapped (I think that was the fancy term). a 32-bit OS can only address 4GBs of memory, including devices that need Memory-Mapped I/O (such as your GPU & graphics memory), so if you have 4GBs of RAM installed, your video card and many other devices will reduce the total amount of RAM available.
