pc is using a 32bit version of windows 7, but has Memory: 4096MB RAM installed, plus some of this is shared with the video card... Display Memory: 3518 MB Dedicated Memory: 1989 MB Shared Memory: 1529 MB a 32bit O/S can only use at max 4 GB, so you have installed up to 4 GB, and I will be able to use about 3.5 GB of it, minus the amount of card ram, as it's totally system ram with a 32bit O/S quote:
With a 256MB graphics card about 3.3-3.5GB of RAM can be addressed and used, assuming you have 4GB fitted. If you fit a graphics card with 1GB of memory only about 2.6-2.8GB of the RAM would be addressable and usable. using the PAE kernel you may get some more use, but that's only if the program and app, motherboard and bios and a mix or hardware is all fully compatible, best and easiest option is use a 64bit O/S, where you wouldn't have or get this issue https://en.wikipedia.org/wiki/3_GB_barrier
